The Amazon rainforest is of crucial importance to the Earth's ecosystem, given its capacity to store substantial amounts of carbon in its vegetation. In 2023, the region experienced unusually high temperatures, reaching 1.5°C above the 1991–2020 average, accompanied by unusual levels of atmospheric dryness from September to November. These conditions were caused by warmer water temperatures in the Atlantic and Pacific Oceans that resulted in diminished moisture transport from the Atlantic to South America, and led to drought in the second half of 2023. An international research team, led by Santiago Botia at the Max Planck Institute for Biogeochemistry, studied how these extreme conditions affected the Amazon rainforest's ability to absorb and store carbon.
