Good morning.

The human-caused climate crisis is undeniably to blame for the deadly heatwaves that have struck Europe and the US in recent weeks, scientists have shown.

How did the scientists analyse the data? The new analysis by the World Weather Attribution group used peer-reviewed methods to quantify the impact of the climate crisis on the recent heatwaves. They used weather data up to 18 July and computer models to compare today's climate, with 1.2C of global heating, with the cooler climate of the late 1800s.

What did the analysis show? The study found the heatwaves in Europe and the US were, as an absolute minimum, made 950 and 4,400 times more likely by global heating - making it virtually certain that they were the result of human-caused emissions. In China, the heatwave was made 50 times more likely.

Was anyone else hurt? No one else at the hospital was killed, but another staffer was wounded. Police later shot the intruder to death after he purportedly fled from the hospital, was found in the nearby city of Gresham and was about to be arrested, authorities said.
