. Understanding climate tipping points
As the planet warms, many parts of the Earth system are undergoing large-scale changes. Ice sheets are shrinking, sea levels are rising and coral reefs are dying off.
While climate records are being continuously broken, the cumulative impact of these changes could also cause fundamental parts of the Earth system to change dramatically. These ‘tipping points’ of climate change are critical thresholds in that, if exceeded, can lead to irreversible consequences.
Minding the gap on tropical forest carbon
Tropical forests are clearly critical to Earth’s climate system, but understanding exactly how much carbon they absorb from the atmosphere, store and release is tricky to calculate, not least because measuring and reporting methods vary. With these measurements paramount for nations assessing the action they are taking to combat the climate crisis, new research shows how differences in estimates of carbon flux associated with human activity can be reconciled.
