In 2015, a strong weather event called El Niño affected tropical areas. Scientists looked at how plants' ability to take in carbon changed in response. They found that forests in the tropics took in more carbon due to more sunlight from fewer clouds. But other types of land saw less carbon uptake because of less rain and higher temperatures, making it harder for plants to thrive. This shows that forests and other areas respond differently to climate changes. The study helps improve how we include these effects in models that predict how carbon and climate interact.
