Even limiting human-made global climate warming to 2°C above preindustrial temperatures would subject young people, future generations and nature to irreparable harm, leading scientists said on Tuesday. The team led by pioneering climate researcher Jim Hansen, now at Columbia University in New York, calls aiming for this internationally-recognised threshold ‘foolhardy’. In a paper published in PLOS ONE, they outline a case for aiming for 1°C that supports efforts to sue the US government for not doing enough.
“Governments are blatantly failing to do their job,” Jim told me. “They know that human-caused climate change is beginning and poses a huge risk to young people and future generations, and they understand that we must phase out fossil fuel emissions. Yet they go right ahead encouraging companies to go after every fossil fuel that can be found!”
As one of the first climate modellers, Jim has long warned about the greenhouse effect caused by the CO2 we emit from burning fossil fuels. On a sweltering June 23, 1988, he famously testified to the Energy and Natural Resources Committee of the US Senate on the dangers of global warming. “It’s time to stop waffling so much and say that the evidence is pretty strong that the greenhouse effect is here,” he told reporters at the time.
Yet Jim remains frustrated at the slow pace of action, and regularly voices it. In 2006 Mary Wood from the University of Oregon Law School saw one of his articles in the New York Review of Books and contacted him. Her work inspired the formation of a team of lawyers who are suing the US federal government, highlighting the principle that US citizens, young and old, have ‘equal protection of the laws’. “I agreed specifically to write a paper that would provide the scientific basis for legal actions against governments for not doing their job of protecting the rights of young people,” Jim recalled.
