A recent study led by NASA, in collaboration with the Commonwealth Scientific and Industrial Research Organisation (CSIRO), highlights a concerning trend: rising temperatures are reducing the capacity of tropical forests to absorb carbon dioxide (CO2). This 50-year analysis, published in the *Proceedings of the National Academy of Sciences*, shows that a one-degree Celsius increase in tropical land surface temperature results in an additional 3.5 Petagrams of CO2 released into the atmosphere each year. Tropical forests, which play a crucial role as carbon sinks, are becoming less efficient as temperatures rise, according to co-author Pep Canadell. He stated, "As soon as you increase the temperature, they perform less well as carbon sinks." The study also sheds light on the carbon-climate feedback mechanism, suggesting that ongoing climate change will further accelerate carbon emissions from both vegetation and soils. Steve Sherwood, Director of the Climate Change Research Centre at the University of New South Wales, noted that these findings are vital for testing climate models and understanding natural variations in CO2 buildup. This research underscores the urgent need to address climate change, as the diminishing capacity of tropical forests to sequester carbon could worsen the impacts of human-induced emissions.
