BRAZIL, May 23 (Reuters) - Britain announced new funding on Tuesday for a major scientific experiment deep in Brazil’s Amazon rainforest that will measure the impact of rising carbon dioxide levels on trees, the British embassy said. Foreign Secretary James Cleverley visited the project north of the city of Manaus, where scientists are building dozens of towers that will inject carbon dioxide into the forest canopy and watch as plants absorb it. The experiment, called AmazonFACE, or Free-Air CO2 Enrichment, will help scientists better understand how the tropical forest might respond to more carbon dioxide in the atmosphere, a greenhouse gas that drives climate change. In addition to raising temperatures, the gas can also fertilize plants, which can affect the water cycle. This could determine how resilient the rainforest will be to climate change in the coming decades. The results obtained from 2024 will be made available to the scientific community worldwide and will improve understanding of how the world's largest tropical forest can help sequester some of the carbon, while also revealing the vulnerability of the Amazon to climate change, the embassy said in a statement..(Reuters)
