We don't have a substantial cushion between today's climate and dangerous warming. James E. Hanson

The head of NASA's Goddard Institute for Space Studies, James E. Hansen, announced the results of break through global warming research last week. The earth's temperature is rising at a much quicker pace than previously anticipated according to research by the nation's preeminent climate scientist. We have little time to reverse the trend.

An example of the dangerous pace of change is emerging on Russia's Eastern Siberian Arctic Shelf. Long-frozen permafrost is beginning to melt due to global warming. This threat was identified years ago due to the potential for highly toxic releases of heat-trapping methane gas.  Recent changes are both a surprise and a cause for alarm. There is more methane gas released from the Russian cauldron "than the CH4 emissions estimate for the entire world ocean." Methane is a "far more potent GHG [greenhouse gas] than CO2" with a greater potential to cause "abrupt climate change."

At the same time, researchers at the Institute for Atmospheric and Climate Science in Zurich developed a more efficient analysis of contributors to global warming. They found man-made causes can now be linked with at least 75% of global warming.

Hansen's warning is brought to life by the methane gas event starting in the Arctic. We are in the danger zone. By the time we know it's too late, it won't matter. Without prompt, concerted action through readily available technologies and programs, we face increasing calamities through midcentury. After that, the displacement, destruction, and death assume unthinkable proportions.

As these evidence-based warnings were issued, the military effort to seize effective control of oil and natural gas regions of the Middle East and Central Asia continued unabated. Ironically, as our rulers engage in endless military conflicts to secure access to oil, they are delivering a weapon of mass destruction, an oil-based economy that will create massive disasters and dislocations that plunge the world into chaos.
