A large group of climate scientists has made a bracing statement in the journal Nature Climate Change, arguing that we are mistaken if we think global warming is only a matter of the next 100 years or so — in fact, they say, we are locking in changes that will play out over as many as 10,000 years.
“The next few decades offer a brief window of opportunity to minimize large-scale and potentially catastrophic climate change that will extend longer than the entire history of human civilization thus far,” write the 22 climate researchers, led by Peter Clark, from Oregon State University.
The author names include not only a number of very influential climate scientists in general but several key leaders behind major reports from the United Nations’ Intergovernmental Panel on Climate Change, including MIT’s Susan Solomon and Thomas Stocker of the University of Bern in Switzerland.
The researchers’ key contention is that we have been thinking about climate change far too narrowly by only projecting outward to the year 2100, which the research says “was originally driven by past computational capabilities.” Rather, we should consider that the long-term consequences of human emissions for global temperatures and sea level will play out over many millennia.
“It’s a statement of worry,” said Raymond Pierrehumbert, a geoscientist at Oxford University and one of the study’s authors. “And actually, most of us who have worked both on paleoclimate and the future have been terrified by the idea of doubling or quadrupling CO2 right from the get-go.”
