One of the deadliest events took place in Colombia, where the June rain fell on saturated soils, leading to a massive landslide that hit Granizal, near Medellín, claiming 27 lives (Alcaldía Bello, 7 July, 2025). In Venezuela, the states of Mérida, Trujillo, and Táchira were among the worst impacted regions. Sustained rainfall in these parts led to the rivers Motatán and Burate to overflow, damaging infrastructure, flooding homes, and sweeping away buildings and vehicles (The Watchers, 25...| World Weather Attribution
The river basin contains the largest rainforest in the world, making it a global hotspot of biodiversity and a key part of the global hydrological and carbon cycle. The river levels are reported to be at lowest levels in 120 years, threatening the estimated 30 million people living in the Amazon basin across several nations including Brazil, Peru, Colombia, Venezuela, Ecuador and Bolivia, by disrupting transportation, isolating communities and killing wildlife. | World Weather Attribution
As the week progresses, southerly winds are drawing in warmer air, pushing temperatures in the South of England toward heatwave conditions by the weekend of the 21st and 22nd of June (Met Office, 2025). In the UK, a heatwave is officially declared when a location experiences temperatures at or above a specific threshold for at least three consecutive days. These thresholds vary by region based on the local climate. In cooler areas, such as much of northern and western Britain, the threshold i...| World Weather Attribution
Researchers from World Weather Attribution assessed the influence of human-caused climate change on dangerous heat waves over the past 12 months, in collaboration with Climate Central and the Red Cross Red Crescent Climate Centre.

More than a dozen fires broke out on March 22nd and 23rd and spread rapidly over the following days. More than 48,000 hectares burned – over 20,000 hectares more than the second most devastating wildfires, in April 2022, and more than ten times the annual average burnt area. | World Weather Attribution
In mid-February 2025, southern Botswana and eastern South Africa were hit by heavy rainfall, sparking severe flooding across the region. The floods claimed at least 31 lives, including 22 in KwaZulu-Natal (Mhlophe-Gumede, 2025), near Durban, and at least nine in Botswana’s capital, Gaborone, amongst them six children (Government of Botswana, 2025). At least 5,000 people have been displaced. The flooding across the border between Botswana and South Africa, caused by heavy rainfall from the 1...| World Weather Attribution
Extreme heat has affected a large region of continental Eastern Africa since mid-February. Extreme daytime temperatures have been recorded in South Sudan particularly affecting people in poor housing and outdoor workers, a very large part of the population. | World Weather Attribution
Every December, people ask us how severe the year’s extreme weather events were. To answer this question, we’ve partnered with Climate Central to produce a report that reviews some of the most significant events and highlights findings from our attribution studies. It also includes new analysis looking at the number of dangerous heat days added by climate change in 2024 and global resolutions for 2025 to work toward a safer, more sustainable world.| World Weather Attribution
Subsequent floods killed more than 200 people, displaced more than 400 people, and saw hundreds of thousands lose access to water and electricity (GDACS, 2024). The death toll is the highest in a flood event in Europe since 1967 and is expected to rise further in coming days (BBC, 2024). | World Weather Attribution
The influence of climate change on tropical cyclones is more complex compared to other types of extreme weather events as impacts are driven by both heavy rainfall and extreme winds. In addition, the surrounding conditions, in particular the sea surface temperatures in the Gulf of Mexico and wider basin, are crucial for the formation of hurricanes. Here, scientists from the United States, the United Kingdom, Sweden and the Netherlands, use several different approaches to investigate the inf...| World Weather Attribution
Although this is a relatively new branch of science that developed over the last 15 years, there are many groups that compute these connections. Our approach in the World Weather Attribution (WWA) collaboration is different in two ways: we attempt to have our results ready as soon as possible after the event, and we try to respond as much as possible to questions posed by the outside world. Both approaches aim to make the attribution studies more useful. Commissions to investigate a disaster ...| World Weather Attribution
Typhoon Gaemi (known in the Philippines as Super Typhoon Carina) strengthened into a tropical storm on July 20th while tracking northwest towards the Philippines. Gaemi did not make landfall in the Philippines but interacted with the ongoing southwest monsoon (known locally as Habagat), causing heavy winds and torrential rainfall from July 22-24 in the northern Philippines. In total, 48 people were killed, with around 6.5 million affected by the severe conditions. 45 landslides were triggered...| World Weather Attribution
Pakistan is reported to have received more than 3 times its usual rainfall in August, making it the wettest August since 1961. The two southern provinces, Sindh and Balochistan, each experienced their wettest August ever recorded, receiving 7 and 8 times their usual monthly totals. The Indus river, that runs the length of the country, burst its banks across thousands of square kilometres, while the intense rainfall also led to urban flash floods, landslides.| World Weather Attribution
