Global warming will exceed the cap set in the 2015 Paris Agreement, though it is uncertain how far this will happen, according to scitechdaily.
According to new research by scientists at the Department of Energy’s Pacific Northwest National Laboratory, the University of Maryland, and the US Environmental Protection Agency, current climate pledges are insufficient to achieve the goals of the 2015 Paris Agreement, and global warming is likely to exceed the 1.5°C limit.
The research suggests that the only way to reduce the extent of this overshoot is for countries to make more ambitious climate pledges and decarbonize their economies at a faster pace, as this will help reduce the amount of time the planet spends in a warmer state.
While an overshoot of 1.5 degrees seems inevitable, the researchers chart several possible cycles in which the overshoot is shortened, in some cases by decades.
Every second saved from overshoot translates into less time to overcome the most damaging consequences of global warming, from extreme weather to rising sea levels, said lead author Gokul Iyer, a scientist along with McJeon at the Joint Global Change Research Institute, a partnership Between PNNL and the University of Maryland, abandoning or delaying more ambitious goals could lead to “negative and irreversible consequences for human and natural systems.”
