When Risks Become Reality: Extreme Weather in 2024 is our annual report, published this year for the first time.

Hot, dry and windy conditions that drove devastating Pantanal wildfires 40% more intense due to climate change

So far this year, wildfires are believed to have burned more than 1.3 million hectares of the Pantanal, the world’s largest tropical wetland and a hotspot of biodiversity.

Climate change, El Niño and infrastructure failures behind massive floods in southern Brazil

Between 24 April and 4 May 2024 over 420 mm of rain fell in Brazil’s southernmost state Rio Grande do Sul, leading to more than 90% of the state being affected by flooding.

Despite known coastal cooling trend, risk of deadly wildfires in central Chile increasing with changing land management in a warming climate

Extreme wildfires in coastal-central Chile have been fuelled by intense and persistent fire-conducive weather conditions in the region since the beginning of the year favouring the spread of severe fires in Viña del Mar (33°S, 71°W) in early February.

Climate change, not El Niño, main driver of exceptional drought in highly vulnerable Amazon River Basin

Wildfires burn through forest in Bolivia emitting large amounts of smoke.

Since mid 2023 the Amazon River Basin (ARB) has been in a state of exceptional drought, driven by low rainfall and consistently high temperatures for the entire year 2023 across the basin.
