tipping
If atmospheric CO2 levels exceed 1,200 parts per million (ppm), it could push the Earth’s climate over a “tipping point”, finds a new study. This would see clouds that shade large part of the oceans start to break up.
The IPCC report sets out the world’s current knowledge of the impacts of 1.5C of warming and clearly shows the dangers of breaching such a limit. However, many scientists are increasingly worried about factors about which we know much less. These “known unknowns” of climate change are tipping points, or feedback mechanisms within the climate system – thresholds that, if passed, could send the Earth into a spiral of runaway climate change.
