Twelve months WWA without Geert Jan

World Weather Attribution (WWA) reports on its activities from October 2021 to October 2022, during which it published eight rapid analyses and several peer-reviewed papers. These studies examined the role of human-induced climate change in events such as heatwaves in India, Pakistan, and the UK, as well as flooding and droughts in various regions. The organization emphasizes that while climate change is a major driver for heatwaves, its role in other events like tropical cyclones can be less clear, often compounding with high levels of vulnerability to increase human impacts.

• Between October 2021 and October 2022, World Weather Attribution conducted eight rapid analyses of extreme weather events. These included a drought in Madagascar where climate change did not increase intensity but high vulnerability led to a food security crisis, and tropical cyclones affecting Madagascar, Malawi, and Mozambique where climate change played a role and impacts were high due to compounding events.
• WWA identified human-induced climate change as a major driver or significant factor in several extreme heat and rainfall events: a record-breaking heatwave in India and Pakistan, heavy rainfall in Brazil, a heatwave in the UK (which caused approximately 2,227 deaths), and extreme monsoon rainfall in Pakistan.
• Analysis of droughts in the northern hemisphere, specifically Western Central Europe, indicated that climate change played a major role in the lack of soil water.
• WWA found that human-induced climate change increases the risk of frost during the growing season in France. While cold nights and frost in March and April are becoming less frequent and less cold, the growing season starts earlier due to warmer days and nights, leaving young leaves more vulnerable.
• The organization notes that while the climate change signal is clear for heatwaves, it is less distinct for tropical cyclones; for example, a 2020 study on flooding in Vietnam caused by tropical cyclones found no climate change signal.
