Worst Global Warming Impacts Avoidable – If We Act Now

The worst effects of global warming are still avoidable according to a new study – if we act now. Researchers at the National Center for Atmospheric Research used a computer model to create two maps: one showing average surface temperature projections for the end of the century if emissions remain unchecked, and another showing temperature projections if emissions are cut by 70 percent.

From MSNBC:

“This research indicates that we can no longer avoid significant warming during this century,” Warren Washington, the study’s lead author, said in a statement. “But if the world were to implement this level of emission cuts, we could stabilize the threat of climate change and avoid catastrophe.”

The computer simulation by the National Center for Atmospheric Research in Boulder, Colo., projected that unchecked levels would mean an Earth 4 degrees warmer. But a 70 percent emissions cut would limit the increase to about 2 degrees, the study found.

“If we follow on the path that (President Barack) Obama has outlined of cutting emissions by 70 or 80 percent and the rest of the world does it, then we can make a big difference on the climate by the end of the century,” Washington told The Associated Press.

Among the projected effects of cutting emissions by 70 percent include slower sea rises, far less Arctic summer ice shrinkage, a reduction in Arctic warming, a reduction of extreme precipitation changes and a stabilized climate system.

We’ve been hearing all about the consequences of doing nothing – from coasts and entire nations getting swallowed up by the sea to extreme droughts that could lead to water wars and famine. If we’ve got a chance to stop these things from happening, we must do it.
