Climate change made Central Europe floods more likely: study
September 25, 2024
The recent deadly floods in Central Europe have shown "the devastating results" of burning fossil fuels, scientists say.

Climate change has doubled the likelihood of the heavy rainfall that led to catastrophic flooding in Central Europe, according to a study released Wednesday.
The flooding in mid-September left 24 people dead and caused damage to property and infrastructure worth billions.
What does the report say?
The report by World Weather Attribution, an international collective of scientists, said the four days of rainfall from Storm Boris was "by far" the heaviest ever recorded in Central Europe.
The scientists said the floods had been made twice as likely because of fossil-fuel induced climate change, which made such rainfall more intense.
Torrential rain, floods wreak havoc in Central Europe
Heavy rainfall has pounded Poland, the Czech Republic, Romania and Austria, forcing rivers from their banks and collapsing dams. Thousands of people have been evacuated, and entire villages remain isolated.

Central Europe under water
Heavy rainfall has led to severe floods in large parts of Central Europe, including southern Poland, the Czech Republic and Austria. At least 17 people have been reported dead, including seven fatalities in Romania. In Austria, authorities have declared the province which surrounds the capital, Vienna, a disaster area. More rainfall is expected. In eastern Germany, river levels are still rising.

Devastation after dam burst in Poland
The masses of water proved too much for a dam in the Glatzer Snow Mountains, near the Polish-Czech border. In the Polish town of Nysa, the Nysa Klodzka River broke its banks, and in Klodzka, some 40 kilometers (25 miles) away, a man was killed by the floods.

Emergency aid in Czech Republic
Entire regions in the Czech Republic are underwater, including the towns of Jesenik and Krnov, on the border with Poland. Tens of thousands of people have been evacuated, some by helicopter. So far, authorities have confirmed three deaths and at least seven missing persons. As many as 20,000 military personnel have been deployed to help deal with the catastrophic aftermath of the floods.

Buckets and boots in Romania
In Cuza Voda, eastern Romania, residents worked together to bail out their community. Armed with buckets and rubber boots, they cleared muddy water from flooded homes. A low-pressure system from northern Italy led to the record rainfall.

Learning from past disasters
In the Czech Republic, rescue workers used dinghies and helicopters to evacuate over 500 residents from Ostrava, a city where the Oder and Opava rivers meet. Across the country, tens of thousands have had to leave their homes. Prime Minister Petr Fiala told Czech public television on Sunday, the worst "is not behind us yet," but expressed hope that the country had learned from past disasters.

Disaster zone surrounding Vienna
This pedestrian bridge on the Danube River in Austria’s capital Vienna was nearly completely submerged on Monday. "The rain has stopped and in many regions, the water levels are receding," Lower Austria’s provincial governor Johanna Mikl-Leitner said. But authorities are still warning of landslides and burst dams. At least five people have been killed in Lower Austria’s catastrophe zone.

Vistula River full to bursting
Sluggish but full to bursting, the Vistula River is slowly flooding the promenade in Krakow, Poland. Following an emergency government meeting in Warsaw on Monday, Prime Minister Donald Tusk has announced a state of natural disaster in the flooded areas in the southwest, to facilitate evacuation and rescue operations.

Rising water in eastern Germany
Tension is rising in eastern Germany, along with the rivers. Authorities in Saxony have reported a water level of more than 5.5 meters in the Elbe River in Dresden. If the water level rises above 6 meters (19.7 feet), the second-highest alert level is declared and built-up areas risk being flooded.

A storm like Boris is likely to occur on average about once every 100 to 300 years in today's climate with 1.3 degrees Celsius (2.3 degrees Fahrenheit) of warming from pre-industrial levels.
However, if the Earth warms to 2 degrees Celsius (3.6 degrees Fahrenheit) above pre-industrial levels — as is expected to happen in the 2050s — such storms will occur 50% more frequently and bring at least 5% more rain, the report added.
What do scientists suggest?
Although the flash study has not been peer-reviewed, it was conducted using scientifically accepted techniques.
"Yet again, these floods highlight the devastating results of fossil fuel-driven warming," said Joyce Kimutai, the study's lead author and a climate researcher at Imperial College London.
"Until oil, gas and coal are replaced with renewable energy, storms like Boris will unleash even heavier rainfall, driving economy-crippling floods."
