Climate change is driving 2022 extreme heat and flooding
The HinduExtreme weather events — from scorching heatwaves to unusually heavy downpours — have caused widespread upheaval across the globe this year, with thousands of people killed and millions more displaced. For heatwaves and extreme rainfall, "we find we have a much better understanding of how the intensity of these events is changing due to climate change," said study co-author Luke Harrington, a climate scientist at Victoria University of Wellington. For their review paper, scientists drew upon hundreds of "attribution" studies, or research that aims to calculate how climate change affected an extreme event using computer simulations and weather observations. "Pretty much all heatwaves across the world have been made more intense and more likely by climate change," said study co-author Ben Clarke, an environmental scientist at the University of Oxford. And while East African droughts have yet to be linked directly to climate change, scientists say the decline in the spring rainy season is tied to warmer waters in the Indian Ocean.
