Climate change increased heavy precipitation associated with impactful Storm Bettina over Black Sea

An attribution study by the World Weather Attribution initiative found that human-induced climate change doubled the likelihood of the heavy precipitation associated with Storm Bettina and increased its intensity by approximately 5 percent. In contrast, the study found no clear evidence that climate change influenced the wind speeds of the event, attributing observed decreases in wind speed to natural variability. The analysis notes that warming increases the proportion of precipitation falling as rain rather than snow, exacerbating flood damages, and that the ongoing Russia-Ukraine war increased the vulnerability of affected populations.

• Human-induced climate change, driven by the burning of fossil fuels, has increased the likelihood of the precipitation observed during Storm Bettina by approximately a factor of 2 and increased the intensity of such an event by about 5 percent.
• There is no evidence that human-induced climate change influenced the wind speeds associated with Storm Bettina; observation-based data showed a decrease in likelihood and intensity, while climate models showed mixed results, suggesting that observed decreases are due to natural variability.
• Climate warming is causing a higher proportion of precipitation during storms like Bettina to fall as rain instead of snow, which results in greater flood damages.
• The impacts of Storm Bettina were exacerbated by the Russia-Ukraine war, which increased vulnerabilities and limited the ability of communities to respond and recover.
• In the current climate, the return periods for the event's wind speeds are 1 in 3 years, while the return period for the associated precipitation is 1 in 20 years.
