When #Climate Change alarmists think your new paper is too alarmist, you know you’ve got a problem. That’s what happened to Carolyn Snyder of the Environmental Protection Agency (EPA), who published a study in “Nature“ this week warning of a catastrophic 13-degree Fahrenheit rise in temperatures. Snyder reached her conclusions by doing an extensive, time-consuming reconstruction of past temperatures using two million years of global sea surface temperatures.
Snyder used ocean sediment cores to create the temperature timeline by cataloging 20,000 such reconstructions and then weighed each one to build a time series of average surface temperatures. After creating this climate record, she says capping all man-made greenhouse gas emissions today still won’t prevent future temperature increases. She calculated a 7-degree Celsius (13 degrees Fahrenheit) rise in a couple thousand years. Other studies have shown that only a complete power shutdown can avoid any future warming.
Climate scientists say the conclusions drawn from the research don’t have the data to back up such claims. Even chief climate guru Gavin Schmidt of NASA’s Goddard Institute for Space Studies (GISS) called the study’s conclusions “simply wrong,” saying there might be a 0.5 to 1.5 degree Celsius or even 2-degree rise if all man-made emissions are stopped now.
Jeffrey Severinghaus of the San Diego Scripps Institution of Oceanography said Snyder’s conclusions aren’t in sync with the data she collected and are based on one fundamental error: the sensitivity of CO2 on glaciations. He says the “problematic conclusion doesn’t flow from the main meat of the paper.”
