Firefighters across Europe are battling multiple wildfires as a record-breaking heat wave grips the continent. In France, the driest year on record has led to fires in the Landes region, forcing over 500 people to evacuate. Fires are also burning in Germany, where unexploded WWII munitions complicate efforts, and in Croatia, where 14 people are hospitalized. The UK experienced its hottest day of the year, with wildfires destroying homes in the West Midlands. Albania and Greece are also facing significant fires, with evacuations underway. The extreme heat is linked to climate change, affecting regions unprepared for such temperatures.

A new study calculates that human-caused climate change doubled the likelihood of the tinderbox weather conditions that sparked Canada’s massive summer wildfires. Thursday’s study by extreme weather research group World Weather Attribution says greenhouse gases make fire weather conditions such as heat, dry air and wind two times more common than they would be in a world without climate change. The fires spread smoke and raised the ire of U.S. President Donald Trump. He blames Canada for not managing its forest properly. Experts say Trump should look in the mirror. One Canadian fire scientist faulted the U.S. and Canada for not cutting back enough on fossil fuels and said the consequences could be deadly.
