Permafrost is ground that remains frozen for two or more years. The warming of the Arctic is thawing vast stretches of permafrost, creating a feedback loop that is accelerating climate change.

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.

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.

Aviation emissions are responsible for around 5% of climate warming, and this share is rising.
