The UK Met Office has announced that it’s launching an experiment that will measure the Amazon rainforest’s response to climate change. Speaking at an event at COP26, researchers explained they will pump controlled amounts of carbon into small areas of the rainforest in Brazil in a process called Free-Air Carbon Dioxide Enrichment (FACE). The experiment – named AmazonFACE – will then measure how this carbon affects the trees, and use this information to get more accurate predictions of how rainforests can help in the fight against climate change. …The Met Office thinks this experiment will allow us to see how trees will react when there’s even more carbon in our atmosphere in the future. They’ve said the AmazonFACE experiment will “work like a time machine” – they’ll replicate what the conditions are projected to be like in 2050, and measure how the forest copes.
