In the fight against climate change, trees are among our strongest allies. Not only do they absorb carbon dioxide from the atmosphere, but they also cool our planet through a process called transpiration. This cooling effect has recently been studied in the Eastern United States, where researchers found that reforestation has significantly cooled the land surface and air temperature, providing a natural solution to the warming climate.
The study, led by Mallory L. Barnes from Indiana University, investigated the impact of reforestation on the climate of the Eastern United States (EUS) during the 20th century. The research team found that forests cool the land surface by 1–2°C annually compared to nearby grasslands and croplands, with the strongest cooling effect during midday in the growing season, when cooling is 2–5°C. Young forests (20–40 years) have the strongest cooling effect on surface temperature. This cooling effect also extends to the near-surface air, with forests reducing midday air temperature by up to 1°C compared to nearby non-forests.
The study’s findings have important implications for climate change mitigation and adaptation. Reforestation in temperate regions, such as the EUS, could provide a complementary set of benefits: mitigating climate change by removing carbon dioxide from the atmosphere, while also helping with adaptation to rising temperatures by cooling surface and air temperatures over large areas.
This research has received widespread attention, including an article by The Guardian, which described the study’s findings as a “stunning feat” in curtailing the soaring temperatures caused by the climate crisis. The recovery of forests in the Eastern United States has helped stall the effects of global heating through transpiration, in which water is drawn up through the roots to the leaves and then released into the air as vapor, slightly cooling the surrounding area.
As we continue to face the impacts of climate change, the importance of trees in mitigating and adapting to these changes cannot be overstated. The Friends of the Saskatoon Afforestation Areas are dedicated to preserving and restoring our forests, recognizing the critical role they play in protecting our planet. Through our efforts, we aim to contribute to a more sustainable and resilient future for all.
