Climate change: effects and evidence

Key ideas1 of 3

Four possible effects

Increasing average global temperature can cause sea-level rise, changes in rainfall and drought/flood risk, more frequent or severe heatwaves, and changes in habitats and species distributions. Warming seawater expands; melting land ice also raises sea level.

Possible climate impacts: coastal flooding from sea-level rise, drought and flooding from rainfall changes, heatwaves affecting health and farming, and habitat changes shifting species distributions.
