Extreme weather events attribution

This study is assessing the role of anthropogenic climate change in the occurrence of prolonged extreme climate conditions favourable for the development of summer 2022 Landes wildfires.

The World Weather Attribution (WWA) initiative was founded in 2014 aiming to study where climate change played a key role and where other factors were the main drivers of the events.

A new study used the 2023 heat wave in Texas and Louisiana as a test case for establishing processes that test out whether particular weather events are climate related.

Climate change is increasingly influencing fire behavior worldwide and intensifying fire smoke, endangering public health from air pollution caused by fires. These are the results of two new climate change impact attribution studies.

UFZ researchers estimate that climate change contributed to roughly one-third of the drought intensity.

The Climate Shift Index (CSI) shows human-caused climate change significantly increased the likelihood of extreme heat in Japan, with temperatures 5-8°C above normal. This highlights the growing impact of climate change on the region’s weather patterns.

In mid September 2024 a very large region in Central Europe, including Poland, Czechia, Austria, Romania, Hungary, Germany and Slovakia experienced very heavy rainfall, breaking local and national rainfall records over the period of four days.

A report by Climate Central finds that human-caused climate change increased heat-related health risks for billions, and made heat extreme events longer and more likely around the globe. Key findings include.

Sicily and Sardinia, important centres of agriculture and tourism have suffered from exceptionally low rainfall and very high temperatures over the last 12 months, culminating in extreme drought conditions from May 2024 onwards.

From August 27-30, 76.6 million people across 19 states will experience at least one day with a Climate Shift Index (CSI) level of 5. A CSI level of 5 indicates that human-caused climate change made this extreme heat at least five times more likely.
