“But every time a hot episode wipes out part of the carbon sink, or in this case all of the sink, it adds credence to the idea that the sink can’t be sustained in the long term,” he says.
Projections of how the carbon cycle will respond to future warming with rising CO2 anticipate a weakening land carbon sink by the end of the century. But those models don’t capture the extreme events that now appear to be driving the carbon cycle, says David Schimel at NASA’s Jet Propulsion Laboratory in California. That may mean we can emit even less CO2 than previously thought. "
The net land carbon uptake 2023 was minimal. Soil and plants suffered so much from heat, drought and fire in South-East Asia, Europe and the Americas, that, even with Africa's CO2 uptake gain due to more rain, the "required" average annual uptake of 7.34 Gt CO2 was only about 1.47 Gt.
I see no reason why this should stay a once-in-a-100-years fluke. I see plenty reasons why this will become a 5 times-per-decade regularity – until the stressed biomes have acclimated.
It also doesn't bode well for ocean acidity when the land carbon sink stops taking up a quarter of our annual emissions. And with rising ocean acidity, the little creatures can't build their shells and die. A major food source – lost. Much, much sooner than previously thought.
