Earth s ability to absorb nearly a third of human-caused carbon emissions through plants could be halved within the next two decades at the current rate of warming, according to a new study in
Science Advances by researchers at Northern Arizona University, the Woodwell Climate Research Center and the University of Waikato, New Zealand. Using more than two decades of data from measurement towers in every major biome across the globe, the team identified a critical temperature tipping point beyond which plants ability to capture and store atmospheric carbon a cumulative effect referred to as the land carbon sink decreases as temperatures continue to rise.

The planet s ability to absorb carbon emissions through plants could be halved within the next two decades at the current rate of warming.
That s according to a new study by Kiwi and US scientists, who warn that crossing a newly identified tipping point could make it harder to slow climate change.
