Deforestation is likely to warm the climate even more than originally thought, scientists warn.

Team - Scientists - University - Leeds - Way

An international team of scientists, led by the University of Leeds, studied the way that reactive gases emitted by trees and vegetation affect the climate.

Their research, published today in Nature Communications, found these reactive gases cool our climate, meaning deforestation would lead to higher temperatures than previously anticipated as less of the gases would be created.

Study - Author - Dr - Catherine - Scott

Study lead author Dr Catherine Scott, from the School of Earth and Environment said: "Most previous assessments on the climate impacts of deforestation have focused on the amount of carbon dioxide that would be emitted, or changes to the way the land-surface exchanges energy and water with the atmosphere.

"But as well as taking in carbon dioxide and giving out oxygen, trees emit other gases that take part in complicated chemical reactions in the atmosphere and there are implications for reducing these gases."

Team - Ways - Gases - Forests - Climate

The team assessed the complex ways in which reactive gases emitted by forests can impact our climate.

Once in the air, gases emitted by forests react with other atmospheric chemicals to form tiny particles. These particles can reflect sunlight back to space, cooling the climate.

Gases - Trees

But the reactive gases emitted by trees can also increase...
