What makes exponential growth so deceptive is that, no matter the growth rate, things always starts out with a period of slow growth, but then quickly change over to a rapid buildup with a characteristic doubling time. Before you know it, you are overrun with rodents, overwhelmed by bacteria, and surrounded by urban sprawl. As Albert Bartlett exclaimed, “The greatest shortcoming of the human race is our inability to understand the exponential function.” And so it goes with the effects of anthropogenic climate change. Within a few generations we will find ourselves inundated by rising oceans at the same time that surging temperatures are making large swaths of the planet uninhabitable. Various positive feedbacks are amplifying the exponential rate of ice melt, rendering useless the IPCC’s linear-model forecasting of global sea level rise(SLR). Upwelling of warm ocean waters are melting both polar regions from the bottom up, and the resulting large freshwater pulses are already slowing down ocean currents. The oceans are losing oxygen. Reflective Arctic sea ice is fast disappearing and a blue ocean event is just around the corner. Melting polar and glacial ice and thermally expanding ocean water have accelerated SLR to the highest rate in at least 6000 years, and an estimated 69 feet SLR has already been set into motion.

From recent satellite data and scientific studies, SLR appears to be in the beginning phase of an exponential growth pattern that will decimate thousands of coastal cities by 2070. Last year we learned that the ice mass loss rate from both Greenland and Antarctica has more than doubled in the past 5 years. Ominously, the West Antarctic ice sheet has been found to be less stable than originally thought. Warming ocean waters are infiltrating beneath the ice shelves and irreversibly melting West Antarctica from below. And more recently we learned that the stability of East Antarctica is being undermined in the same insidious way. In fact, Antarctic ice shelves have been thinning up to 70% faster than average in some spots. These ice shelves extend out over the polar waters and are what hold back and support all the land-based glacial ice. Once the ice shelves are eroded, land ice will have an open path to slide down into the ocean and melt, greatly accelerating SLR. Congruent with these disturbing trends is the revelation that SLR has been increasing much faster than we thought in the last couple decades. The rate of change per year has been 3.2mm since 1990 versus 1 to 1.4mm for the previous nine decades. That is a 100% to 200% increase in just the last couple decades. Adding to SLR is the frenzied pumping of groundwater by drought-stricken farmers and municipalities. In a cruel twist, SLR will only worsen fresh water scarcity by causing inland salt water intrusion, raising the fresh water table, and altering freshwater streamflow. SLR will reshape geography, changing coastal estuaries, wetlands, and forests. Radically altering such natural topographical features will inevitably change rainfall patterns. Permanent and intermittent flooding will allow for the expansion of tropical diseases such as cholera and malaria, and more frequent and intense hurricanes and monsoons will increase the number of cases and duration of exposure to pathogens and diseases.

Dr. James Hansen has argued all along that 5 meters of sea level rise by the end of the century is possible, saying:

“…IPCC treats sea level change basically as a linear process. It is more realistic, I believe, that ice sheet disintegration will be non-linear, which is typical of a system that can collapse.”

Hansen had posited a doubling time of ten years for land ice melt rates, but satellite data has revealed a doubling time that is occurring twice as fast. This would put those measurements more in line with the projections of physicist/climatologist Paul Beckwith who calculates we may be on track for a 7 meter(23 feet) SLR by 2070 if the doubling period of ice cap melt from both Greenland and Antarctica hold up over this century. Paul tells me that the recent developments described above support his views. Interestingly, there was a study published in 2013 that stated an eventual 23 foot SLR would be locked-in by the end of the century under BAU emissions based on best estimates of global temperature sensitivity to pollution and the finding that every degree Fahrenheit of global warming results in a global average long-term SLR of 4.2 feet. That study, however, did not take into account the exponential rate of ice melt now occurring.

What will 23 feet SLR look like? For some fairly accurate visuals, take a look at Nickolay Lamm’s work. In the U.S. alone, 1500 communities would be underwater at high tide. With its porous limestone substrate, South Florida would be completely lost:

Most nuclear plants are located along waterways for easy access to water for coolant purposes, making them vulnerable to storm surge flooding in a world of expanding oceans. Since decommissioning a nuclear power station is a long, expensive, and dangerous process, I can’t imagine we will have the time, money, or forethought to safely get rid of all these time bombs before most of them are swallowed up by the ocean and go Fukushima on the world. In addition, melting ice sheets and SLR can set off the most destructive of earthquakes and volcanoes. The toxic wreckage left behind by capitalist industrial civilization will linger around for millennia to haunt anyone who does manage to survive in this hellish future.

The year is now 2015 and the human population is still shooting skyward as if there is some sort of bright techno-utopian future on the horizon, the high priests of capitalism are still praising endless growth, fossil fuels are still the predominant energy source on the planet, and the masses still can’t get enough of celebrity gossip. No need to worry about the future. I’m sure if there’s a buck to be made by holding back the rising tides, we can count on some capitalist lurking in the shadows to fix the problem. Sea walls will do the trick, right? Humans are looking more and more like ants on a floating turd: “When the log turns over we will all be dead…”

Update May 8, 2015:

A new study shows another ominous jump in the rate of growth in SLR. Robert Scribbler blogs about the staggering 30% increase here:

…new findings paint an even starker picture. For a recent study, headed by Shuang Yi and published on April 30 in Geophysical Research Letters provides evidence that, since 2010, annual rates of global sea level rise have shown a strong uptick. The study, entitled An Increase in the Rate of Global Mean Sea Level Rise Since 2010, notes:

The global mean sea level (GMSL) was reported to have dropped 5 mm due to the 2010/11 La Niña and have recovered in one year. With longer observations, it is shown that the GMSL went further up to a total amount of 11.6 mm by the end of 2012, excluding the 3.0 mm/yr background trend. A reconciled sea level budget, based on observations by Argo project, altimeter and gravity satellites, reveals that the true GMSL rise has been masked by ENSO-related fluctuations and its rate has increased since 2010. After extracting the influence of land water storage, it is shown that the GMSL have been rising at a rate of 4.4 ± 0.5 mm/yr for more than three years, due to an increase in the rate of both land ice loss and steric change.

In short, the study finds an average rate of sea level rise of 4.4 mm per year, or 30% faster than the annual rate from 1992 to 2009, during the period of 2010 to 2013. For these, more rapidly rising, sea levels the study identifies clear causes. The first is an increasing rate of land ice loss. The second is what is termed as ‘steric change’ — a scientific phrase that both identifies ocean thermal expansion due to warming combined with changes in ocean salinity, which also impacts sea surface height.

I emailed this recent finding to Paul Beckwith and here’s what he had to say:

SLR has risen 8cm since 1992 and jumped by 1cm just in the last year:

Looking back over the last century, we see what looks like the beginnings of an exponential rise in recent times:

We already have 20 to 75 feet of SLR locked in. It’s just a matter of how fast it will happen and you can bet that it won’t be a gradual, linear rise. If you follow the news, glaciologists always seem to be amazed that things are happening much faster than expected. Here are a couple recent headlines:

Greenland’s Undercut Glaciers Melting Faster than Thought

GREENLAND’S MELTING ICE IS RUNNING OFF FASTER THAN WE THOUGHT

Government estimates of SLR over this century do not take into account rapid melt of polar ice sheets:

…Most of the models projecting future sea level rise assume a gradual acceleration of sea level rise through this century and beyond as ice melt gradually accelerates. Our knowledge of how sea level rose out of the past ice age paints a very different picture of sea level response to climate change. At the depth of the last ice age, about 18,000 years ago, sea level was some 420 feet below present level as ice was taken up by large continental ice sheets. Subsequent ice melt was not a gradual acceleration and then deceleration process. Rather it was a series of very rapid pulses of sea level rise followed by pauses. These rapid pulses of rise, from three to thirty feet, were fast enough to leave drowned reefs, sandy barrier islands, tidal inlet deltas, and other coastal deposits abandoned across the continental shelf. That is what happens when climate change warms enough to destabilize some ice sheet sector. It rapidly disintegrates, resulting in a rapid rise.

We have significantly warmed atmospheric climate and that is resulting in an accelerated ice melt of the surface of the Greenland Ice Sheet. Much of the surface of the Ice Sheet is darkening as the dust and black carbon in the ice concentrates on the melting surface. This accelerates heat adsorption further accelerating surface ice melt.

More importantly, warmed ocean water is accelerating ice melt in both polar regions. The warming North Atlantic Ocean and Arctic Ocean have been accelerating ice melt all around Greenland since about 1995 as this dense, ‘warm’ ocean water enters the deep outlet glacial fjords that penetrate far in under the Ice Sheet. ‘Warm’ water from upwelling because of increased wind shear around Antarctica is also penetrating in under outlet glaciers to the West Antarctic and East Antarctic Ice Sheets. Each of these ‘warm’ waters are only 2-4 degrees Celsius, but are doing a powerful amount of warming, and we are creating a basically unlimited supply of warmth to the oceans.

The beginnings of polar Ice Sheet melt are showing positive reinforcing feedbacks which are rapidly accelerating the rate of melt far beyond anything originally anticipated. Water on the melting ice surface adsorbs more heat accelerating surface melt; melt water percolating down through the ice lubricates the base permitting faster motion, which results in more extensive fracturing. Water percolating through the fractured ice accelerates ice melt and warms the ice resulting in softening of the ice and further acceleration. And so on. With the rapid melting of the Arctic Ocean pack ice and warming of the Arctic Ocean, release of additional carbon dioxide and methane from decaying organics in the melted permafrost and melting of methane hydrates on the Arctic continental shelf, this melt is accelerating and seems irreversible. We are most certainly witnessing the onset of a rapid pulse of sea level rise…

Storm surges will become exponentially more damaging as sea levels rise. Global warming will amplify and increase the frequency of super El Niños and anomalies like the “Blob”. This year’s record storms will be the new normal in coming years. If you live in Florida(aka the new Atlantis), sell your home while you can.

That may not sound like a lot, but it’s enough to cause enormous economic and societal problems. What’s great about this paper is they also include a discussion on the limitations of their work. For instance, they state that their method cannot deal with processes that are independent of the warming rate (such as a sudden collapse of an ice sheet).

Unresponsive and Corrupt Governments

Another election cycle passes and the American people responded with the lowest voter turnout since WWII. The staged events of today’s political rallies will soon be composed solely of people paid off with corporate bribes to wave flags and chant slogans. As ever more corporate money floods into the faux democratic process, participation by the average citizenry has plummeted. Americans are now more disillusioned with the charade of “American democracy” than at any time in history:

Confidence in Congress as an institution is at 7%, the lowest measurement in history and lower than any other institution tested, including organized labor, banks and big business. Views of the honesty and ethics of members of Congress are at 8% on average, one percentage point above lobbyists, but one point below car salesmen… – link

We are also undoubtedly becoming more callous and insensitive to our fellow-man when a 90-year-old gentleman is arrested for feeding the homeless from a church kitchen. In fact, we’ve lost all our humanity and exchanged it for the almighty dollar. Neoliberal capitalism has permeated very aspect of social and civic life, creating a new epitaph for the demise of such a mean-spirited culture —‘death by dollars’.

You Are What You Eat

I just became aware of Dr. Suzanne de la Monte’s studies on the food industry’s use of sugar in all its products in order to fabricate a consumer “bliss point” for maximizing sales. Capitalist industrial civilization has bred a morbidly obese creature conditioned to overeat processed food spiked with sugar, fat, and salt. A high-fructose diet has undoubtedly turned the cognitive skills of many into mush. John Oliver recently used a clip from her work in his takedown of the sugar industry:

“De la Monte has done her research by feeding healthy rats the equivalent of a North American diet, complete with all the sugars and fat. All her rats ended up demented.” – from the documentary The Secrets of Sugar

The Dopamine Rush of Fossil Fuels

With the recent elections the lunatics have taken control of the asylum. Oklahoma Republican James Inhofe, recipient of 2012 Rubber Dodo Award, is in line to chair the Senate’s top environmental job, and incoming Senate Majority Leader Mitch McConnell says his first priority will be to “do whatever I can to get the EPA reined in.” At least a dozen newly-elected climate science deniers will be there to help Mitch compete with China and India in a race to global mass extinction.

The IPCC stated back in 2007 that emissions would have to peak in 2015 to avoid a rise of 2°C, but since that is not going to happen, they are putting their hopes in technology that could pull CO2 out of the atmosphere while conceding that such techniques are “uncertain” and “limited”. Mankind’s grave is already deep enough, yet we keep digging. Just as China’s coal consumption has registered a drop for the first time this century, India has announced it will pick up the slack by planning to double its coal production to meet the country’s soaring energy demand. Poland has rejected the IPCC target of zero emissions by 2100. In the U.S., new data has revealed that climate change has become the most politically divisive issue in the U.S.

According to energy expert Nate Hagens, modern-day carbon man’s metabolic energy consumption makes each of us a 30-ton primate. It appears the Pavlovian conditioning of modern man to energy dense fossil fuels and capitalist wealth have irrevocably hacked and rewired his brain’s reward system. The autopsy results for the age of the Anthropocene will read: “fossil fuel overdose” and “suicide by CO2”.

Hydropower is Not Green

Even overlooking the GHG emissions from a dam’s construction and maintenance, hydropower is seen by some as a “renewable energy source”, yet it is apparently a much larger source of methane emissions than once thought, perhaps releasing nearly as much as the methane emissions that accompany the burning of fossil fuels:

…In 2012 study, researchers in Singapore found that greenhouse gas emissions from hydropower reservoirs globally are likely greater than previously estimated, warning that “rapid hydropower development and increasing carbon emissions from hydroelectric reservoirs to the atmosphere should not be downplayed.”

Those researchers suggest all large reservoirs globally could emit up to 104 teragrams of methane annually. By comparison, NASA estimates that global methane emissions associated with burning fossil fuels totals between 80 and 120 teragrams annually…

Nonetheless, industrial civilization is currently damming up every large river on the planet:

The Unraveling Web of Life

The WWF(World Wildlife Fund) released its biennial ‘Living Planet Report’ which some on Twitter are calling the ‘Dead Planet Report’. The silence of mass extinction draws ever nearer…

The report writers, based on data kept by the Zoological Society of London, studied 10,380 populations of 3,038 species of amphibians, birds, fish, mammals and reptiles from 1970 to 2010. Over these four decades, the average decline of these vertebrate species was 52 per cent – all in less than two human generations.

Amongst freshwater species the population decline was a staggering 76 per cent, owing to habitat loss, land fragmentation, pollution and invasive species.

In the same period terrestrial species declined by 39 per cent through unsustainable land use and increased poaching, often spurred on by wildlife crime syndicates.

Marine species declined also by 39 per cent, to include large migratory seabirds, many shark species and also sea turtles.

A major contributory factor to marine loss of life was through by catching (accidentally catching, in certain fish net sizes, species which were of no market value and then casting these dead fish overboard), illegal fishing and overfishing of the same fishing grounds.

Currently we need a 50 per cent bigger Earth to allow the regeneration of the natural resources we consume…

…By 2050, we will have an extra 2.4 billion people in our world, with urban populations increasing from 3.6 billion in 2011 to 6.3 billion. In 1970, there were only two megacities (over 10 million people) – New York and Tokyo; in 2014 there are 28 such cities – 16 in Asia, three each in Europe and Africa, four in Latin America and two in North America, all totalling 12 per cent of the world’s urban population.

The United Nations (UN) predicts that in 2025, there will be 37 megacities with eight new ones in Asia. Also in the pipeline are meta-cities – conurbations of over 20 million people – through the amalgamation of megacities…

…The report interestingly mentions that the diversity of human languages in our world is strongly correlated to areas of high plant diversity. Some linguists have predicted that 90 per cent of the world’s languages will expire by the end of this century…

Here is an interesting graph created by Paul Chefurka which shows that the combined biomass of humans with their farm animals exceeds the natural carrying capacity of the earth sevenfold:

In the graphic, the “wild animal” biomass doesn’t include insects, bacteria, or marine organisms.

I used three data sources to develop the chart: a paper by world-respected ecological scientist Vaclav Smil, called “Harvesting the Biosphere”, linked below; world population estimates from the Wikipedia article of the same name; and the UN’s Medium Fertility variant for the human population in 2050 (9.6 billion).

The definition I used for Global Carrying Capacity is, “The biomass the planet can support without the assistance of human technology or fossil fuels.” The impact of human activity has gradually eroded the Earth’s carrying capacity over time, which is why I show the red dotted line sloping down to the right. The degree of erosion is very hard to estimate. My guess is that we may have lost around 25% by this point, some of which would of course be naturally regenerated over time in the absence of human activity. Any biomass above that dotted line has to be supported by human technology and energy supplies (which at this point are mostly from fossil fuels).

The conclusion is that we have been living in the midst of an accelerating Global Mass Extinction Event for over 100 years already. Unfortunately we’ve been too fixated on human issues like economics and politics to even notice, let alone realize what it means. Those who did realize the significance, both to wildlife and the human species, have been powerless to act in the face of economics and politics.

Paul gives the following further explanation for the graph:

The definition one uses for “carrying capacity” is so loose as to make it quite arbitrary. Here’s the definition I used: “The global carrying capacity is the total biomass of the organisms under consideration that the planet can support without the assistance of technology or fossil fuels.”

Accordingly, I estimated the carrying capacity in this case as being about the same as the world’s wild animal biomass in 10,000 BCE, with the assumption that the unassisted carrying capacity of the world would have been fully utilized at that point. I estimated the wild animal biomass in 10,000 BCE as being somewhat less than the combined wild and domestic animal biomass in 1900, per Smil. I made it lower in order to account for the technological intensification of farming already well under way by that time.

The slope of the carrying capacity line is arbitrary, because it’s impossible to determine how much we have actually eroded the world’s unassisted carrying capacity. We just know that we have. I chose the slope to correspond to my belief that we’ve eroded it by about 25% at this point. The actual slope is therefore somewhat editorial.

The Dalai Lama says, “Affection, a sense of community and a sense of concern for others are not some kind of luxury. They’re about the survival of humanity,” but the socio-economic system that rules the world is characterized by hyper-individualism and self-interest devoid of moral constraints. A system that enshrines greed and mocks equity and the public good will never be able to find a solution to the tragedy of privatizing the commons.

All lights are about to go out. No more electricity. All forms of transportation are about to stop, and the planet Earth will soon have a crust of skulls and bones and dead machinery. And nobody can do a thing about it. It’s too late in the game. Don’t spoil the party, but here’s the truth: We have squandered our planet’s resources, including air and water, as though there were no tomorrow, so now there isn’t going to be one.

Still on Track for the Collapse of Modern Civilization

6th Mass Extinction, Climate Change, CO2 Emissions and GDP, Collapse of Industrial Civilization, Economic Collapse, Economic Growth, IPCC, Mass Die Off, Methane Time Bomb, MIT's Climate and Energy Outlook 2014, Money = Energy, Ocean Acidification, Professor Jonathan Overpeck

Two recent pieces of scientific evidence really hammer home the predicament of modern industrial civilization, and they have to do with the fact that our globalized, just-in-time economic model is hopelessly wed to carbon-based energy. Once one understands this, then there can be no delusions about why we are on such a catastrophic trajectory of greenhouse gas emissions. As was explained in a previous post, GDP is fundamentally and directly linked to CO2 emissions. Below, two graphs(click to go to source) illustrate this fact:

It’s not really about evil fossil fuel companies, although they do certainly exert enormous political clout and do conspire to protect their business model by doing such things as spreading doubt on climate change science, but as with all corporations, externalizing social and environmental costs is endemic to the profit system and the coercive forces of competition in capitalist markets.

Firstly, there is the graph submitted by Professor Jonathan Overpeck, a climate scientist for the past 30 years, Professor of Geosciences and Atmospheric Sciences, and Co-Director Institute of the Environment, Univ. of Arizona:

This clearly shows we are firmly on track for hitting 3.2-5.4°C warming by the end of the century or sooner. This kind of rapid warming is incompatible with most life on Earth. To get an idea of what the world will be like at 3°C once lag time catches up to real time, we can look back 3 million years ago in the Pliocene Era when CO2 levels were similar to today and temperatures were 3°C warmer:

The northern hemisphere was free of glaciers and icesheets, beech trees grew in the Transantarctic mountains, sea levels were 25 metres higher [Climate Dynamics, 26, 249-365], and atmospheric carbon dioxide levels were 360-400 ppm, very similar to today. There are also strong indications that during the Pliocene, permanent El Nino conditions prevailed. Hansen says that rapid warming today is already heating up the western Pacific Ocean, a basis for a coming period of ‘super El Ninos’ [Proc. Nat. Acad. Sci., 103, 39, 14288-93]…

…The collapse of the Amazon is part of the reversal of the carbon cycle projected to happen around 3 degrees, a view confirmed by a range of researchers using carbon coupled climate models. Vast amounts of dead vegetation stored in the soil – more than double the entire carbon content of the atmosphere – will be broken down by bacteria as soil warms. The generally accepted estimate is that the soil carbon reservoir contains some 1600 gigatonnes, more than double the entire carbon content of the atmosphere…

…Three degrees would likely see increasing areas of the planet being rendered essentially uninhabitable by drought and heat. Rainfall in Mexico and central America is projected to fall 50 per central. Southern Africa would be exposed to perennial drought, a huge expanse centred on Botswana could see a remobilisation of old sand dunes [Nature, 435, 1218-21], much as is projected to happen earlier in the US west. The Rockies would be snowless and the Colorado river will fail half the time. Drought intensity in Australia could triple, according to the CSIRO, which also predicts days in NSW above 35 degrees will increase 2 to 7 times.

With extreme weather continuing to bite – hurricanes may increase in power by half a category above today’s top-level Category Five – world food supplies will be critically endangered. This could mean hundreds of millions – or even billions – of refugees moving out from areas of famine and drought in the sub-tropics towards the mid-latitudes. As the Himalayan ice sheet relentlessly melts with rising temperatures, the long-term water flows into Asia’s great rivers and breadbasket valleys — the Indus, Ganges and Brahmaputra, the Mekong, Yangtse and Yellow rivers — will fall dramatically. If global temperatures rise by three degrees, and that’s becoming the un-official target for western governments, water flow in the Indus is predicted to drop by 90 per cent by 2100. The lives of two billion people are at stake.

As the Arctic continue to warm, melting permafrost in the boreal forests and further north in the Arctic tundra is now starting to melt, triggering the release of methane, a greenhouse gas twenty times more powerful than CO2, from thick layers of thawing peat. The West Siberian bog is estimated to contain 70 billion tonnes of CO2. Prof. Sergei Kirpotin, a botanist at Russia’s Tomsk State University, says: “There’s a critical barrier… Once global warming pushes the melting process past that line, it begins to perpetuate itself.” The West Antarctic ice sheet would likely to irreversibly melt.

At 5-6°C:

Five degrees
• Five degrees of warming occurred during the Eocene, 55 million years ago: breadfruit trees grew on the coast of Greenland, while the Arctic Ocean saw water temperatures of 20C within 200km of the North Pole itself. There was no ice at either pole; forests were probably growing in central Antarctica.
• The Eocene greenhouse event was likely caused by methane hydrates (an ice-like combination of methane and water) bursting into the atmosphere from the seabed in an immense “ocean burp”, sparking a surge in global temperatures. Today vast amounts of these same methane hydrates still sit on subsea continental shelves.
• The early Eocene greenhouse took at least 10,000 years to come about. Today we could accomplish the same feat in less than a century.

Six degrees
• At the end of the Permian period, 251 million years ago, up to 95% of species were extinct as a result of a super-greenhouse event, resulting in a temperatures rise by six degrees, perhaps because of an even bigger methane belch than happened 200 million years later in the Eocene.
• One scientific paper investigating “kill mechanisms” during the end-Permian suggests that methane hydrate explosions “could destroy terrestrial life almost entirely”. Acting much like today’s fuel-air explosives (or “vacuum bombs”), major oceanic methane eruptions could release energy equivalent to 10,000 times the world’s stockpile of nuclear weapons.

Another valuable website worth reading describes, degree by degree, the changes that will happen to the Earth from anthropogenic global warming. Due to the unpredictable nature of the internet and web pages disappearing, I have saved that essay as an entire screenshot here.

Keep in mind that the IPCC, an institution that has consistently underestimated the effects of anthropogenic climate change, states that in order to stay below 2°C of warming, emissions will have to be 40-70% lower than they were in 2010 by 2050 and at zero by the end of the century, “or could possibly even require taking carbon dioxide out of the atmosphere, a controversial proposition.” As the Keeling Curve grows ever steeper year after year, the Hail Mary of a techno-fix inevitably becomes the only option left. However, concomitant with the CO2 problem is the acidification of the oceans which will require a miracle solution as well. As was explained in a previous post, if all emissions stopped yesterday, we would still be locked into a warming of 2.65°C.

The second important piece of information is a recent MIT study:

Above graph, from MIT’s Climate and Energy Outlook 2014, shows a drastic rise in global energy consumption by fuel type.

If CO2 levels were to double to 800ppm:

If carbon dioxide levels reach 800 ppm, ocean pH is projected to drop another .3 to .4 units (Today we have measured a decline of .1 pH units from 8.2 to 8.1 in the last century) – one of the scenarios projected by the Intergovernmental Panel on Climate Change by 2100 –raising levels of hydrogen ion, H +, 100 to 150 percent (Orr et al., 2005). As this happens and it will take “tens of thousands of years” for the chemistry of the oceans to return to pre-industrial levels, at least that is what the Royal Society of Britain proclaims. – link

We’re already seeing massive die-offs of oysters and scallops from an acidification (PH-decline) of 0.1PH, but what would happen at a drop of 0.3-0.4 units(150+% more acidic than at the beginning of the industrial revolution)?:

“…we found that reef development ceased below pH level 7.7… Ultimately, what we observed was that the diversity of reefs progressively declines with increasing CO2. At concentrations similar to those predicted for the end of this century at a ‘business as usual’ emissions scenario, the “coral reef” observed was depauperate and lacked the structural complexity of present healthy tropical coral reefs. These changes are simply due to ocean acidification, i.e., even without the projected +2°C warming of the oceans associated with rising greenhouse gases. The 0.5° warming we have already observed in the tropics in the last 50 years has already caused mass coral bleaching events and declining coral calcification.” – link

—————

Ocean acidification could trigger economic devastation

…The authors of the report, released today from the Third Symposium on the Ocean in a High-CO2 World, review the current science on the effects on marine organisms, and write that there is a “medium confidence” level that shellfish harvests will decline. There is also a medium confidence level that economic damage will result from impacts on coral reefs, with tourism, food and shoreline protection suffering. The size of this is unclear but one estimate is for $1 trillion in damage from coral loss alone.

How larger species will fare as oceans acidify is less clear. The report gives only a “low confidence” rating to the idea that top predators and fin fish catches will be reduced. But any losses in this area could hit hard the 540 million people whose livelihoods depend on such fisheries.

Scientists also have a “very high confidence” that the ocean’s capacity to take up carbon decreases as waters acidify. So even larger cuts in human greenhouse gas emissions than currently envisaged may be needed to meet targets set to limit global warming as a result, the authors write….

…The report authors also say that the acidity of the oceans could increase by 170% by the end of the century, corresponding to a drop in surface ocean pH by 0.32. This occurs under a pessimistic scenario of high human emissions. Since the industrial revolution, surface ocean pH has dropped from 8.2 to 8.1. As pH is a logarithmic scale, the increase in acidity since the industrial revolution could reach around 170% under this scenario.

Under lower-emissions scenarios, this decrease would be around 0.07. But current emissions show no sign of dropping to those necessary to achieve such a goal, cautions Riebesell.

“If you look at current trajectories we’re no way below the [high emissions scenario],” Riebesell says. “Of course we hope the human race is smart enough to learn at some point and turn the wheel round.” – link

As long as the shelves in the local grocery store are filled with relatively cheap food, the television is broadcasting the usual “bread and circus”, water is flowing from the faucet, and other creature comforts of industrial civilization are on tap, homo economicus will blithely ride into the dark future of mass extinction, tectonic shifts of the biosphere, and the collapse of an unsustainable lifestyle.

CNN is running a program of their newscasters’ family roots. Why do I feel like this is a slick PR campaign to put a main street face on the mainstream media? Sorry, but I still don’t trust them and we’re still on track for the collapse of modern civilization despite all their smug smiles.

This blog is cross-posted at The Spiral Staircase. Feel free to comment here or there.

To orient oneself in life, a person chooses from among myriad narratives, typically assembling a hodgepodge worldview out of diverse parts. According to Oswald Spengler, cultural artifacts (e.g., the arts, humanities, and sciences) arise “needing the guidance of inspiration and … developing under great conventions of form.” The very same can be said of our origin and orientation stories, ancient or contemporary. Narratives intertwine and need not necessarily be discrete, mutually exclusive, or competing, even though that’s what’s often implied by time-worn tensions underlying science vs. religion, sometimes understood more philosophically as logos vs. mythos. Indeed, they cohere despite conflicts of logic and their being ahistorical. The power of subscription and consensus overcomes all objections.

If a master narrative exists, it ought to be simply reality obtained, though that is probably visible to only a small percentage of people able to apprehend the world clearly. For the rest, scales not yet having fallen from the eyes, the considerable benefit of hindsight can help clarify the view, but only if one has sufficient nerve to behold it honestly. Instead, our dominant inspirational narratives promulgate a wide variety of incompletely fulfilled hopes and desires. Few such promises bear much resemblance to reality, those of economists, politicians, and clerics demonstrating the most striking discontinuities from the actuality experienced by ordinary folks. A Chris Hedges article at TruthDig.com called “The Folly of Empire” discusses this departure from reality in his characteristically erudite style (apologies for the long nested quote):

… absurd promises of hope and glory are endlessly served up by the entertainment industry, the political and economic elite, the class of courtiers who pose as journalists, self-help gurus like Oprah and religious belief systems that assure followers that God will always protect them. It is collective self-delusion, a retreat into magical thinking. “The American citizen thus lives in a world where fantasy is more real than reality, where the image has more dignity than the original,” Daniel J. Boorstin wrote in his book The Image: A Guide to Pseudo-Events in America. “We hardly dare face our bewilderment, because our ambiguous experience is so pleasantly iridescent, and the solace of belief in contrived reality is so thoroughly real. We have become eager accessories in the great hoaxes of the age. These are the hoaxes we play on ourselves.”

I don’t usually lump into the mix entertainers, sports figures, gurus hawking self-help books and programs, or media pundits offering half-baked analyses because only idiots expect truth from them, but perhaps I should include them considering their stranglehold on the public’s wasted attention. Most of today’s media-driven narratives rely on conventions, gestures, and rhetoric that are notoriously predigested and therefore immediately swallowed by the guffawing crowd, disinviting additional analysis or careful consideration. This bears a curious family resemblance with intellectual conditions that sparked the Reformation. Further, because such mediated (or should I say medieval?) content is composed largely of fiction, pageantry, and untethered conjecture, no time is needed for the narrative to actualize. Hope functions in the present tense and requires no closure.

Perhaps the quintessential inspirational narrative was trotted out by the Obama campaign back in 2008, which relied on promises (empty, we later found out) to fulfill everyone’s desire for a better life, calling on hope and change to achieve those promises. Another religious hope narrative promises to enhance one’s afterlife, earned in earthly realms through achievements in social justice and the judgment of posterity. Both adopt time-honored conventions and are part of what is described in Morris Berman’s book Wandering God as the ascent tradition. Significant among those conventions is orientation along a vertical axis as seen, for instance, in easy acceptance of the legitimacy of hierarchy (and therefore egregious power, wealth, and class stratification and imbalance) and a longing for transfiguration, transcendence, and communion with god (or the gods) above.

Looking back across history, evidence of “progress” and growth is legion. However, most of those achievements are demographic, material, and technological, each having their unique and unintended blowback. What’s notably lacking as we sally forth into the 21st century is the ability to transcend our own base nature, which is characterized by corruption, violence, stupidity, short-term gratification, and inability to achieve the utopian dreams that populate the minds of many despots. So that same history is marked by downturns and setbacks. One might even say that the overall upward trend of history is pockmarked by periodic scars. Still, nothing just yet has stalled the hubris of history rising (unless domestic peak oil in the 1970s and global peak oil a few years back prove to have been among the first of a series of turning points). And judging from blog traffic and commentary, the steady stream of negative assessments in scientific literature, and news reports telling of weather and ecological calamities with increasing frequency and severity, awareness is beginning to dawn on even the most congenital optimists (plus some fools and the average ignoramus) that what goes up must eventually come down. Since history has gone vertical, hard limits must eventually assert themselves.

The plethora of charts, tables, graphs, and infographics that evidence not just rising trends but verticality is frankly astonishing. Sometimes a gradually ascending slope is observable within a short timeframe, such as receding glacial ice documented in Chasing Ice. Other times it takes long traces of historical, evolutionary, or even geological time to observe. Even short timeframes often conceal effects that lie handily beyond normal perception, but we luckily have scientists trained to recognize short- and long-term trends. Too bad they’re uniformly ignored and/or pilloried by a public spoon fed the blandishments of corporate marketing and political propaganda. Typically, ascending curves (whether geometric, logarithmic, or exponential) don’t appear to be walls (limits) when viewed from the far left or from within a narrow time band, meaning microscopically close. Zoom out or to the right, however, and the trend pointed into the stratosphere is readily apparent, such as in the following video (animation) of CO2 concentrations in the atmosphere:

Similar x-y coordinate graphs showing, for instance, energy use per capita and human population growth demonstrate the same trajectory but at much briefer durations. Trendlines are mathematical abstractions, like fiat currency being printed into existence. At some point, gravity takes hold and drags everything back to earth (reality), though that eventuality can be forestalled for a surprisingly long time. The return trip down various vertical trends is approaching ever more quickly as lift skyward fizzles like an Icarus nightmare. Or in the case of atmospheric carbon, we can’t stop the rising trend we unwittingly initiated from blowing through the roof and rendering the earth uninhabitable.

It’s often said there is no such thing as an atheist in a foxhole. Presented with the likelihood or certainty of battlefield death, holdouts succumb and cash the eternal-life insurance card of a last-minute profession of faith. Same as death-bed conversions. Thousands of years of philosophy and religion might prepare us to face our inevitable demise if we bothered to learn anything worthwhile besides how to make money, and yet in all our frailty, many of us cannot accept that our final departure is merely a fact of life, not a gateway or journey to somewhere else. (Um, opinions vary on this, obviously.) The final departure of Homo sapiens sapiens is even harder to contemplate.

So what foxhole moment awaits us? Here’s one: the Intergovernmental Panel on Climate Change (IPCC) released in late September 2013 a publication by Working Group I of the Fifth Assessment Report, which presents the underlying physical science behind climate change (used to be called global warming). The IPCC website states that “The Fifth Assessment Report (AR5) is being released in four parts between September 2013 and November 2014. It will be the most comprehensive assessment of scientific knowledge on climate change since 2007 when Fourth Assessment Report (AR4) was released.” Preparation of these reports has been ongoing for decades already, and the difficulty of their assemblage assures that they’re already out of date at the time they’re released. Being the work of governments, AR5 is also reputed to be remarkably conservative in its conclusions, as contrasted with prophesying near-term human extinction (NTE or NTHE) as those of us unconstrained by geopolitics have begun to do (mostly taking our cues from Guy McPherson of Nature Bats Last). That’s not a gambit for attention, BTW. It’s about a soul-destroying a realization as there is, and no one comes to admit it easily.

The likelihood of anyone plunging into the 2216 pages of this first of four parts of AR5 is, well, dismal. One could easily level the accusation that the IPCC is burying its findings behind pages and pages (and pages) of prefatory material; acknowledgements; missing or incomplete figures, tables, and citations (to be inserted when?); technical and executive summaries; glossaries; references; and dry obfuscation. That’s not really the case, though; the data and discussion are abundant and available for anyone capable of deciphering it. Technical and scientific analysis and discussion is exactly what Working Group I delivers in these chapters:

Introduction
Observations: Atmosphere and Surface
Observations: Ocean
Observations: Cryosphere
Information from Paleoclimate Archives
Carbon and Other Biogeochemical Cycles
Clouds and Aerosols
Anthropogenic and Natural Radiative Forcing
Evaluation of Climate Models
Detection and Attribution of Climate Change: from Global to Regional
Near-term Climate Change: Projections and Predictability
Long-term Climate Change: Projections, Commitments and Irreversibility
Sea Level Change
Climate Phenomena and their Relevance for Future Regional Climate Change

I downloaded the report and sought something succinct to quote, such as an answer to the question “Just how fucked are we, anyway?” but the technical summaries proceed with this sort of dry, useless, blank, uninformative text:

The primary purpose of this Technical Summary is to provide the link between the complete assessment of the multiple lines of independent evidence presented in the 14 chapters of the main report and the highly condensed summary prepared as the WGI Summary for Policymakers. The Technical Summary thus serves as a starting point for those readers who seek the full information on more specific topics covered by this assessment. This purpose is facilitated by including pointers to the chapters and sections where the full assessment can be found. Policy-relevant topics, which cut across many chapters and involve many interlinked processes in the climate system, are presented here as Thematic Focus Elements, allowing rapid access of this information.

The WGI Summary for Policymakers is not contained within the larger report but both can be found at this link. It’s unclear how much of the report was used in preparation of this story at National Geographic, but the story provides five takeaways from WGI:

On the extreme weather front, the report concludes it is “very likely” that cold days and nights have decreased, while warm days and nights have increased, since 1950 …
The oceans have warmed with “virtual certainty,” the report concludes, at a rate of about 0.2 degrees Fahrenheit (0.11 Celsius) per decade since 1970 in the upper 246 feet (75 meters) of surface water …
What about those polar bears? Sea ice (as well as glaciers and ice sheets) has declined overall since 1970 …
Sea level rise has happened, and will happen in the future, as a result of global warming, the report finds …
More than half of the global warming observed since 1950 has a human cause, largely from the greenhouse gas effects of gases such as carbon dioxide emitted from burning fossil fuels ….

The ellipses indicate brief discussion behind each takeaway. The conclusions are hedged, of course, relying on observations of what’s happened so far and omitting extrapolation of trends that go vertical. Even the three levels of confidence communicate not certainty of our fate (exact details TBD) but hope that projections are subject to change or we can do something to reverse things or at least forestall the worst. Like IPCC, National Geographic is yet to have its foxhole moment even though the evidence is staring them ghoulishly in the face. If one is at all engaged in this subject, I suppose it makes sense to stay hunched in the hole chain-smoking cigarettes and making do with what meager rations and sleep are available. My sneaking suspicion is that the go order will come quickly enough to catch lots of shivering, quivering, wavering souls before they get to their last eternal hope. In the meantime, the fat lady is singing, the coal-mine canary has expired, pigs are flying, and hell has frozen over. We’re vertical against the wall, facing the firing squad, and what’s left to do, though no one knows just quite when, is to get horizontal.
