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 present, numerous environmental researchers are warning of future resource shortages. The list of them is large and includes water, oil, a variety of minerals and metals, as well as other materials.
Yet, most people carry on as if they do not hear the message at all. They refuse to cut back in their dreams of continuing economic growth.
In relation, part of the problem with them is perhaps an inability to make connections. For the most part, they seem to have little or no idea about the collective consequences of their individual behaviors.
