Scientists say warming is increasing faster than at any time in at least 3 million years. There is no guide for what comes next.
If you think of Earth’s climate system as a backyard swing that’s been gently swaying for millennia, then human-caused global warming is like a sudden shove strong enough to disrupt the usual arc and buckle the chains.
And if humans keep heating the planet with greenhouse gas pollution, the climate swing could lock Earth into a hothouse trajectory, as parts of the system feed on their own momentum, even if emissions are reduced later, an international team of scientists warned Wednesday in a new paper published in the journal One Earth.
Their analysis covers 16 key Earth systems, including oceans, ice sheets and forests, that are likely to destabilize if the planet continues to warm. If large parts of the Amazon rainforest and tropical coral reefs die, they absorb less carbon dioxide, triggering a dangerous chain reaction of warming.
If Earth’s climate starts on a hothouse trajectory, it would represent a “global tipping point” as the heating sustains itself even if greenhouse gas emissions drop, said lead author William Ripple, a distinguished professor of ecology at Oregon State University and a leading researcher on climate tipping points.
In the backyard, that’s the moment when the push is so hard that the swing hesitates at the top, just long enough to show that the ride may not be under control anymore and the chains are being tested.
