The urban heat island effect is a phenomenon whereby cities experience higher air temperatures than the surrounding countryside, making them more vulnerable to a warming Earth.

Forests take in carbon from the air and store it in wood, plant matter, and under the soil. Restoring them is an important option for combating climate change.

Cities concentrate people into small areas for good reason, but this makes them major sources of greenhouse gases and uniquely vulnerable to climate risks.

Wildfires are becoming more frequent and severe as a result of climate change, as forests in arid parts of the world become hotter and drier.
