Study shows extreme rainfall made twice as likely by planet-heating pollution as EU promises €10bn in aid

• Global heating ‘doubled’ chance of heavy rain in Europe in September

Jarmila Šišmová did not know what to expect when rain began to pound the small town of Litovel in the Czech Republic, and she was not prepared for the nightmare that would await her once it stopped.

The authorities told Šišmová to leave her home, so she took her children to their grandmother to wait out the storm. As the water level rose, a neighbour – one of the few on her street who stayed behind – checked the front of the house and saw the sandbags holding firm. But from the back, Šišmová would soon find out, the flood had burst into the building, drenching her belongings in dirty brown water.
