Global Warming Disaster Closer Than Thought, Says NASA

The study conducted by NASA and the Columbia University Earth Institute appears in the journal Atmospheric Chemistry and Physics. Its lead author is James Hansen, director of NASA's Goddard Institute for Space Studies in New York.
The forecast effects include "increasingly rapid sea-level rise, increased frequency of droughts and floods, and increased stress on wildlife and plants due to rapidly shifting climate zones," according to the NASA announcement.
By heralding the new research paper, NASA is endorsing science that places considerably more urgency on the need to reduce emissions to avoid "disastrous effects" of global warming than was evident in the recent reports from the world's scientists coordinated by the Intergovernmental Panel on Climate Change.
As the tipping points pass, "there is an acceleration, potentially uncontrollable, of emissions of vast natural stores of greenhouse gas," according to Hansen, who reviewed the study for ABC News. Hansen explains that dangerous feedback loops are being tracked in various regions of the planet.
Many studies have reported feedback loops already observed in thawing tundra, sea beds and drying forests.
Hansen also points out that dark and therefore heat-absorbing forests are now expanding toward the Arctic, replacing lighter-colored areas such as tundra and snow cover.
