Weather vs Climate Explained
- Weather is the short-term atmospheric condition, while climate is the long-term trend of weather over decades.
- Climate change alters the probability of extreme weather events like heatwaves.
UK Heatwave Definition & Pattern
- A heatwave is defined by the Met Office as three consecutive days above a heat threshold that varies by region.
- The UK has experienced three heatwaves this summer, an unusual and early pattern.
Attribution of Heatwaves to Climate Change
- Scientists now model human-induced climate change to assess how it increases the likelihood of specific events.
- The current heatwave temperatures are about five times more likely due to human-caused climate change.
