Scientists run climate ‘time machine’ as Brazil prepares for COP30 summit
Financial Express Mumbai
|October 29, 2025
DEEP IN BRAZIL'S Amazon, scientists have built a “time machine” pumping carbon dioxide into the rainforest canopy to simulate atmospheric conditions predicted for the future to gauge how the biome adapts — an open question to be discussed at the COP30 United Nations climate summit hosted by the country next month.
At the AmazonFACE project near Manaus, the largest city in the Amazon, six rings of steel towers loom above the jungle canopy, each surrounding groups of 50 to 70 mature trees.
After baseline testing, scientists will fumigate trees in three of the rings with carbon dioxide at levels simulating climate forecasts for coming decades, while the rest serve as control samples.
