Rapid Climate Shift

From Wikipedia:
An abrupt climate change occurs when the climate system is forced to transition to a new state at a rate that is determined by the climate system itself, and which is more rapid than the rate of change of the external forcing.[1] Past events include the end of the Carboniferous Rainforest Collapse,[2] Younger Dryas,[3] Dansgaard-Oeschger events, and possibly also the Paleocene-Eocene thermal maximum.[4] The term is also used within the context of global warming to describe sudden climate change that is detectable over the time-scale of a human lifetime. One proposed reason for the observed abrupt climate change is that feedback loops within the climate system both enhance small perturbations and cause a variety of stable states.[5]
Timescales of events described as 'abrupt' may vary dramatically. Changes recorded in the climate of Greenland at the end of the Younger Dryas, as measured by ice-cores, imply a sudden warming of +10°C within a timescale of a few years.[6] Other abrupt changes are the +4 °C on Greenland 11,270 years ago[7] or the abrupt +6 °C warming 22 000 years ago on Antarctica.[8] By contrast, the Paleocene-Eocene Thermal Maximum may have initiated anywhere between a few decades and several thousand years.

RAPID CLIMATE CHANGE

The global warming debate, despite having vociferous proponents on each side, appears to have been decided. Global warming is very real, and it is the preeminent danger to human civilization today. The rising global temperature threatens to create catastrophic weather systems, crop failures, disease outbreaks, and water shortages worldwide.
Emissions of greenhouse gases like carbon dioxide and methane are trapping heat within the Earths’ atmosphere, slowly increasing the overall temperature.These emissions are the byproduct of our modern way of life, and to halt them would require a voluntary shift in the very structure of our society, a move unprecedented in human history.
To not take action, however, would be to alter the very chemical composition of our planet. Life on Earth evolved over hundreds of millions of years to survive within very specific conditions, and those conditions are changing

Post-Crash Fascism: Planning for the Apocalypse

STEVEN MEISEL / VOGUE ITALIA
Climate change is happening faster than initially predicted, and its impacts are already upon us in the form of more extreme weather events, desertification, ocean acidification, melting glaciers and incrementally rising sea levels.
The scientists who construct the computer models that analyze climate data believe that even if we stop dumping greenhouse gases into the atmosphere, CO2 levels are already so high that we are locked into a significant increase in global temperatures. Disruptive climate change is a certainty even if we make the economic shift away from fossil fuels.
Incipient climate change is already starting to express itself in the realm of politics.
Climate change arrives in a world primed for crisis. The current and impending dislocations of climate change intersect with the already-existing crises of poverty and violence. I call this collision of political, economic and environmental disasters the catastrophic convergence. By catastrophic convergence, I do not merely mean that several disasters happen simultaneously, one atop another. Rather, I argue that problems compound and amplify each other, one expressing itself through another.
Societies, like people, deal with new challenges in ways that are conditioned by the traumas of their past. Thus, damaged societies, like damaged people, often respond to new crises in ways that are irrational, shortsighted, and self-destructive. In the case of climate change, the prior traumas that set the stage for bad adaptation, the destructive social response, are Cold War–era militarism and the economic pathologies of neoliberal capitalism. Over the last 40 years, both of these forces have distorted the state’s relationship to society – removing and undermining the state’s collectivist, regulatory and redistributive functions, while overdeveloping its repressive and military capacities. This, I argue, inhibits society’s ability to avoid violent dislocations as climate change kicks in.

planning for apocalypse

A slew of government reports have discussed the social and military problems posed by climate change. In 2008. Congress mandated that the upcoming 2010 Quadrennial Defense Review – the policy document laying out the guiding principles of US military strategy and doctrine – consider the national-security impacts of climate change. The first of these investigations to make news, a 2004 Pentagon-commissioned study called “An Abrupt Climate Change Scenario and Its Implications for United States National Security,” was authored by Peter Schwartz, a CIA consultant and former head of planning at Royal Dutch/Shell, and Doug Randall of the California-based Global Business Network.The report was made at the behest of octogenarian military theorist cum imperial soothsayer Andrew Marshall. Known to his followers as Yoda, after the wrinkled, dwarflike puppet of Star Wars fame, Marshall got his start at the RAND Corporation in 1949 as a specialist on nuclear Armageddon and its alleged survivability. He moved from RAND to the Pentagon during Richard Nixon’s presidency and served every president since. (It is interesting to note the presence of atomic-era Cold Warrior physicists among both the climate-change denialists and the military adaptationists. In his book How to Cool the Planet, Jeff Goodell remarks on the same set’s infatuation with the high-tech solutions promised by geoengineering, in particular Lawrence Livermore Laboratory’s Lowell Wood, a tie-dye wearing disciple of Edward Teller.)
Schwartz and Randall’s report correctly treats global warming as a potentially nonlinear process. And they forecast a new Dark Ages:
Nations without the resources to do so may build virtual fortresses around their countries, preserving resources for themselves … As famine, disease, and weather-related disasters strike due to the abrupt climate change, many countries’ needs will exceed their carrying capacity. This will create a sense of desperation, which is likely to lead to offensive aggression in order to reclaim balance … Europe will be struggling internally, large numbers of refugees washing up on its shores and Asia in serious crisis over food and water. Disruption and conflict will be endemic features of life. Once again, warfare would define human life.
In 2007, there came more reports on climate and security. One, from the Pentagon-connected think tank CNA Corporation, convened an advisory board of high-ranking former military officers to examine the issues – among them General Gordon Sullivan, former chief of staff, US Army; Admiral Donald Pilling, former vice chief of naval operations; Admiral Joseph Prueher, former commander in chief of the US Pacific Command; and General Anthony Zinni, retired US Marine Corps and former commander in chief of US Central Command. That report envisioned permanent counterinsurgency on a global scale. Here is one salient excerpt:
Climate change acts as a threat multiplier for instability … Unlike most conventional security threats that involve a single entity acting in specific ways at different points in time, climate change has the potential to result in multiple chronic conditions, occurring globally within the same time frame. Economic and environmental conditions in these already fragile areas will further erode as food production declines, diseases increase, clean water becomes increasingly scarce, and populations migrate in search of resources. Weakened and failing governments, with an already thin margin for survival, foster the conditions for internal conflict, extremism, and movement toward increased authoritarianism and radical ideologies. The US may be drawn more frequently into these situations to help to provide relief, rescue, and logistics, or to stabilize conditions before conflicts arise.
Another section notes:
When a government can no longer deliver services to its people, ensure domestic order, and protect the nation’s borders from invasion, conditions are ripe for turmoil, extremism and terrorism to fill the vacuum … the greatest concern will be movement of asylum seekers and refugees who due to ecological devastation become settlers.
In closing the report notes, “Abrupt climate changes could make future adaptation extremely difficult, even for the most developed countries.”
Another report from 2007, the most scientifically literate of the lot, titled The Age of Consequences: The Foreign Policy National Security Implications of Global Climate Change, was produced by the Center for Strategic and International Studies and the Center for a New American Security. Its prominent authors included Kurt Campbell, former deputy assistant secretary of defense; Leon Fuerth, former national security advisor to Vice President Al Gore; John Podesta, former chief of staff for President Bill Clinton; and James Woolsey, former director of the Central Intelligence Agency.
Age of Consequences laid out three plausible scenarios for climate change, each pertaining to different global average-temperature changes. The authors relied on the Fourth Assessment Report of the Intergovernmental Panel on Climate Change but noted, “Recent observations indicate that projections from climate models have been too conservative; the effects of climate change are unfolding faster and more dramatically than expected.” The report conceives of future problems not in terms of interstate resource wars but as state collapse caused by “disease, uncontrolled migration, and crop failure, that … overwhelm the traditional instruments of national security (the military in particular) and other elements of state power and authority.” Green ex-spook James Woolsey authored the report’s final section laying out the worst-case scenario. He writes:
In a world that sees two meter sea level rise, with continued flooding ahead, it will take extraordinary effort for the United States, or indeed any country, to look beyond its own salvation. All of the ways in which human beings have dealt with natural disasters in the past … could come together in one conflagration: rage at government’s inability to deal with the abrupt and unpredictable crises; religious fervor, perhaps even a dramatic rise in millennial end-of-days cults; hostility and violence toward migrants and minority groups, at a time of demographic change and increased global migration; and intra- and interstate conflict over resources, particularly food and fresh water. Altruism and generosity would likely be blunted.
