LUBBOCK, Texas, July 19 (UPI) — Choices made today about greenhouse gas reduction could affect climate change for hundreds, even thousands of years, U.S. researchers say.
Climate scientists at Texas Tech University have issued a report of advice and recommendations for possible outcomes of choosing future emissions targets, a university release said Friday.
“Many of us have had the experience of going to the doctor and receiving advice on how to improve our health,” climate researcher Katherine Hayhoe said.
“Then, it’s up to us to decide how much we are willing to change,” Hayhoe said. “In a similar way, this report presents the probabilities of certain impacts at different levels of global temperature increase.”
The report estimates changes in precipitation, stream flow, wildfires, crop yields and sea level rise that can be expected with different degrees of greenhouse gas warming.
“We, the scientists, can’t make the decisions of how much risk is acceptable,” Hayhoe said. “That’s a political decision. Rather, we’re trying to give policymakers the information they need to make these decisions.”
