Plants’ Ability to Absorb CO2 is Declining
EcoTechNews
It's simple: plants are absorbing less carbon dioxide. The study by James and Sam Curran shows a 0.25% annual decline since 2008. This is happening because of climate change - wildfires, droughts, extreme temperatures. They're killing plants' ability to store carbon.
We've got a problem. Rising CO2 levels were supposed to fuel plant growth, increase natural sequestration. But that's not happening. The Curran team's data analysis says the Earth's natural sequestration mechanisms are shifting, with big implications for global warming. If this trend continues, we're looking at a 30% higher global CO2 concentration than if sequestration rates had kept increasing at the 1960s rate of 0.8% per year.
There's a lot at stake. CO2 emissions must decrease by at least 0.3% per year to maintain current atmospheric levels. That's a tough ask, given the historical annual increase of 1.2%. We need to restore sequestration capacity, and that means regenerative agriculture, reforestation, ecosystem restoration. But can we do it fast enough? Will we reverse the decline in carbon sequestration, or will the planet's natural carbon sinks keep weakening, making the climate crisis worse?
