Plants Are Losing Their Ability to Absorb Carbon Dioxide

 EcoWatch - Our planet’s plants and soils reached the peak of their ability to absorb carbon dioxide in 2008, and their sequestration rate has been falling ever since, according to a new analysis by a father-and-son team in the United Kingdom.

At first, the added carbon led to warmer temperatures, vegetation growth and a longer growing season. Once a tipping point was reached, however, the combination of heat stress, wildfires, drought, flooding, storms and the spread of new diseases and pests led to a reduction in the amount of carbon plants can soak up.

“The rate of natural sequestration of CO2 from the atmosphere by the terrestrial biosphere peaked in 2008. Atmospheric concentrations will rise more rapidly than previously, in proportion to annual CO2 emissions, as natural sequestration is now declining by 0.25% per year,” the authors of the study wrote. “This effect will accelerate climate change and emphasises the close connection between the climate and nature emergencies. Effort is urgently required to rebuild global biodiversity and to recover its ecosystem services, including natural sequestration.”
