Tipping points: How do we know when we are tripping?

William P. Hall on March 28, 2022

The idea of a ‘tipping point’ is more than academic. Once you trip over it you are on a downhill slide towards Hell at the bottom of the hill

In 20 years of studying how ecosystems absorb carbon, here’s why we’re worried about a tipping point of collapse

From rainforests to savannas, ecosystems on land absorb almost 30% of the carbon dioxide human activities release into the atmosphere. These ecosystems are critical to stop the planet warming beyond 1.5℃ this century – but climate change may be weakening their capacity to offset global emissions.

This is a key issue that OzFlux, a research network from Australia and Aotearoa New Zealand, has been investigating for the past 20 years….

The biggest absorbers of atmospheric carbon dioxide in Australia are savannas and temperate forests…. as effects of climate change intensify, ecosystems such as these are at risk of reaching tipping points of collapse.
