[Untitled] U.S. Department of the Interior, U.S. Geological Survey news release: "The United States faces the potential for abrupt climate change in the 21st century that could pose clear risks to society in terms of our ability to adapt. "Abrupt" changes can occur over decades or less, persist for decades more, and cause substantial disruptions to human and natural systems.

But, despite the CCSP’s description of these synthesis reports as “decision support resources,” they are not really designed to meet the needs of decisionmakers at the national level and in states and local communities for planning and technical assistance in coming up with real-world resilience-building responses to the likely acceleration of harmful climate change impacts discussed in the report.

[Truthout - All Articles] t r u t h o u t | Faster Climate Change Feared: The climate change debate usually leaves out the ultimate causes of most earth destruction, which is capitalism enshrining human consumption and population growth as gods. Read the book The Enemy of Nature and see the absolute proof that unless we stop the borrow/spend/bulldozer mentality that charecterizes Liberals and Conservatives alike, that we will soon destroy the biosphere will also creating an enslaved world of humans who struggle for oxygen, water, food and freedom while being held down by the fascist police state elites and their political/government/corporate enablers who increasingly control our lives.

[Michael Moore - This Just In] MichaelMoore.com : Agencies' report warns of faster climate change: However, the assessment also suggests that some other feared effects of global warming are not likely to occur by the end of the century, such as an abrupt release of methane from the seabed and permafrost or a shutdown of the Atlantic Ocean circulation system that brings warm water north and colder water south. But the report projects an amount of potential sea level rise during that period that may be greater than what other researchers have anticipated, as well as a shift to a more arid climate pattern in the Southwest by midcentury.

[Untitled] Abrupt Climate Shifts May Come Sooner, Not Later: In the interior United States, a widespread drought that began in the Southwest about 6 years ago could be the leading edge of a new climate regime for a wider region. Cook, who heads Lamont's Tree Ring Lab, says that periodic droughts over the past 1,000 years have been driven by natural cycles in air circulation, and that these cycles appear to be made more intense and persistent by warming.

This will in turn increase the rate of warming' --Leemans and Eickhout (2004), 'Another reason for concern: regional and global impacts on ecosystems for different levels of climate change,' Global Environmental Change 14, 219-228

[Untitled] Abrupt climate shifts may move faster than thought - Care2 News ...: Climate can and does change rapidly and often the changes are brief and last only a decade or so before they head in the other direction. In the 1940’s, 50’s, 60’s and into the late 70’s the world was cooling and the temperatures in the late 70’s were some of the lowest recorded since the little ice age, but beginning in the 80’s we began witnessing an increase in temperatures that rivaled those of the 1930’s, temperatures that hadn’t been seen since the medieval warm period.

When it comes to abrupt climate shifts, he said, “We need to be prepared to deal with it in terms of policymaking, keeping in mind it’s a low-probability, high-risk scenario.
