How hot was it today in Europe? This hot:

Firefighters in Spain are battling a major wildfire that probably started after a heap of manure self-ignited amid the intense European heat wave. 

Around 10,000 acres of forest and other vegetation were affected by the blaze near Tarragona in the country's north-east, according to the Catalan regional government.

Authorities said the fire likely began when an "improperly managed" pile of manure self-combusted in the heat, causing sparks.

Tomorrow may also see the hottest temperature ever recorded in France. Fun times.
