Climate Impacts: Global extreme weather events this week

Let's explore the extreme weather events that have unfolded worldwide during the week from April 10-17, driven by the rise in global warming.

Brazil: Floods

A “waterfall-like flood” struck Petrópolis, Brazil, with some areas receiving nearly three times their monthly average rainfall. A federal emergency was declared as the rain caused widespread damage and displacement.

Congo and Namibia: Heavy rains

In Kinshasa, the capital of the Democratic Republic of Congo, heavy rains and flooding killed over 70 people and displaced more than 5,000. The Congolese president blamed climate change for making flooding worse in the country. In northern Namibia, weeks of heavy rain claimed at least 16 lives in the Oshana region.

India & Nepal: Heavy rains & Lightning

Over 100 people were killed following heavy rain across India and Nepal. Meteorological departments issued multi-hazard warnings, as thunderstorms battered some regions while others endured dangerous heatwaves. Delhi recorded 40.2°C in its first heatwave of the season and the hottest April day in 3 years, while Maharashtra reported 34 cases of heatstroke – 10 more than the same period last year.

Russia: Wildfires

Wildfires in Siberia, Russia, marked the start of the region’s wildfire season, killing one person, injuring 5, and destroying 65 buildings. Wind speeds up to 144 km/h and a snow drought contributed to the rapid spread.

Phoenix: Heatwave

In the US, Phoenix hit its first triple-digit temperature of 2025 – nearly a month earlier than usual. Forecasters had signalled the temperature at Phoenix Sky Harbor International Airport could hit 100, marking what would have been the earliest date on record for the city to hit triple digits.

United Kingdom: Forest Fires

In the UK, Scotland and Wales battled wildfires amid extreme risk warnings. According to climate scientists, prolonged dry spells have paved the way for these wildfires. A mild winter allowed for more foliage growth, followed by spring droughts, which made this year particularly bad for wildfires.
