A new report released by National Center for Atmospheric Research today reports that the worst effect of global warming could still be reversed if aggressive measures are implemented quickly to reduce greenhouse gas emissions.
Candace Lombardi at Greentech reports that:
“The computer simulation showed that if greenhouse gas emissions can be held at 450ppm–the target labeled as reasonably achievable by the U.S. Climate Change Science Program, if the world reduces emissions by 70 percent–the global temperature would rise by about .6 degrees Celsius (about 1 degree Fahrenheit) by the year 2100. If human-made emissions are left unchecked, the model predicted that greenhouse gas levels would rise to 750ppm by 2100, causing a global temperature increase of 2.2 Celsius (about 4 degrees Fahrenheit).” (my emphasis)
