Scientists Tell Senate Panel: Climate Change Is Here and Disaster Costs Will Be Huge
Climate scientists who appeared Wednesday morning before a Senate committee hearing on climate change and extreme weather impacts had stark warnings for the lawmakers: climate change is here, climate change is man-made, and climate change is going to cost us big time.
Dr. James McCarthy, professor at Harvard University and lead author of several climate impact studies by the Intergovernmental Panel on Climate Change (IPCC) and other international papers, told the committee that there is "widespread agreement among specialists who devote their careers" to monitoring key indicators of global warming.
He acknowledged that, of course, climates fluctuate on a yearly basis, but that the mounting evidence of a warming world was changing the baseline of those fluctuations.
"In the future," he said, as greenhouse gases continue to increase, natural events like El Nino cycles, "Will wreak even more havoc as they break old records for warm and wet conditions across much of the globe, because they will be occurring upon a higher baseline of warming."
