Dom Spracklen explores how the terrestrial biosphere and atmosphere interact—and how those interactions are being reshaped by human activity. He is author of over 200 scientific papers spanning air pollution, climate change, forest fires, deforestation, and ecosystem conservation. His research has shown how tropical forests help regulate local climate through cooling their surroundings, providing reliable rainfall and maintaining clean, unpolluted air. This work provides clear evidence of the vital benefits that standing tropical forests deliver for local communities. He works with environmental organisations, both in the UK and across the tropics, to help protect and restore nature.
