A new study highlights the significant role of reforestation in the eastern United States in mitigating climate crisis-induced temperature rises.
Oliver Milman reports for The Guardian.
In short:
- The eastern U.S. has experienced a "warming hole" where temperatures have stabilized or decreased, contrary to global trends.
- Reforestation in this region, covering an area larger than England, has been a key factor in this localized cooling effect.
- The cooling is primarily due to trees' transpiration process, which releases water vapor into the air, reducing surrounding temperatures.

"Nature-based climate solutions like tree planting won’t get us out of this climate change problem."

Why this matters:
This study underscores the power of reforestation in combating climate change, particularly in urban areas facing extreme heat. It's a vital reminder that alongside reducing emissions, nature-based solutions like tree planting play a crucial role in our overall climate strategy.
Researchers say "proforestation" policies are the fastest and most effective way to draw excess CO2 out of the atmosphere.
