Europe is the world’s fastest-warming continent and 2024 was the warmest year on record, with record temperatures in the central, eastern and southeastern regions, according to the latest European State of the Climate 2024 report published jointly by the World Meteorological Organization (WMO) and Copernicus Climate Change Service (C3S).

Severe storms and flooding claimed 335 lives last year and affected around 413,000 people. Scientists also reported that the east was extremely dry, while the west witnessed warm and wet conditions.

“This report highlights that Europe is the fastest-warming continent and is experiencing serious impacts from extreme weather and climate change. Every additional fraction of a degree of temperature rise matters because it accentuates the risks to our lives, to economies and to the planet. Adaptation is a must,” WMO Secretary-General Celeste Saulo said in a press statement.

The report has a silver lining. The proportion of electricity generation by renewables in Europe reached a record high in 2024, and now stands at 45%.

This is the eighth annual report, released in April every year, and the second that has been published jointly with Copernicus, the European Union’s earth observation program.

Climate change hotspots

Europe experienced the most widespread flooding since 2013. Almost one-third of the continent’s river network experienced flooding that exceeded the ‘high’ flood threshold.

The continent saw both hot and cold extremes. The numbers of days with ‘strong’, ‘very strong’ and ‘extreme heat stress’ were all the second highest on record.

Nearly 60% of Europe saw more days than average with at least ‘strong heat stress’. But there was a record low number of days with at least ‘strong cold stress’ too.

“These extreme events led to an estimated 18 billion euros of damages, 85% of which is attributed to flooding,” said Samantha Burgess, deputy Director of C3S during a press conference to discuss the report’s key findings.

All European regions saw a loss of ice due to record temperatures. Glaciers in Scandinavia and Svalbard saw their highest rates of mass loss on record. In September, fires in Portugal burned around 110,000 ha (1100 km2) in one week, representing around a quarter of Europe’s total annual burnt area. An estimated 42,000 people were affected by wildfires in Europe.

“We observed the longest heatwave in southeastern Europe and record glacier mass loss in Scandinavia and Svalbard, an archipelago between Norway and the North Pole. But 2024 was also a year of marked climate contrasts between eastern and western Europe,” Carlo Buontempo, C3S director said during the press conference.

While the entire continent is not a climate change hotspot, experts said that some areas within Europe do fit those criteria.

“A good example of this is the Mediterranean region, which is widely recognized as a climate change hotspot with above average warming, a projected decrease in precipitation, rising drought, risk wildfires and strong socio economic and ecological vulnerabilities. Similarly, the alpine region in Europe is also experiencing above average warming and sensitive changes in the cryosphere,” Burgess said.

Impact of funding cuts to NOAA now visible

In recent months the United States government has cut funding to the country’s climate monitoring system, the National Oceanic and Atmospheric Administration (NOAA).

This has affected scientists who have been laid off from their jobs and has also limited the number of observations NOAA makes around the world. Scientists acknowledged that this has affected the quality of the report that uses data from multiple data sources.

“Observations are absolutely fundamental to monitor what we’re doing, and NOAA is providing a lot of observations. What we’ve seen since March is that there has been a drop in the number of observations delivered by NOAA due to funding cuts,” said Florence Rabier, Director-General of European Centre for Medium-Range Weather Forecasts or ECMWF.

“Any observation loss is a loss for climate monitoring, for calibration of satellite, for verification of forecasts. So, in terms of both science and observations for weather and climate, I think it would indeed have an impact on the whole community,” she told the press conference.

Progress on some fronts

The report spotlighted some progress that was made by cities and countries. In 2024, Europe generated 45% of its electricity needs from renewables, up from 43% in 2023.

The number of EU countries where renewables generate more electricity than fossil fuels has nearly doubled since 2019, rising from 12 to 20, according to reports.

In addition, around 51% of European cities have adopted climate adaptation plans, which is almost double the 26% in 2018. Urban areas are responsible for 70% of all carbon emissions globally and the United Nations has pushed for cities to take action as they can play a big role in our response to the climate crisis.

Around 100 scientists in Europe and around the world worked on this report, and WMO head Saulo emphasized the need for continued action: “Every fraction of a degree matters. Climate adaptation is not the future option. It’s a very real necessity now, today, not tomorrow.”
