Explainers

Sea levels around the world are rising because of climate change, as warming ocean waters and melting ice cause the oceans to encroach on the world's coasts.

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

Hurricanes are intense tropical cyclones. These storms are becoming stronger as climate change warms the oceans.

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