@cnn: Europe's summer of extraordinary heat and drought has pushed some of its rivers to record lows, revealing long-submerged relics from ancient bones to century-old shipwrecks. The remains of what's believed to be an ancient mammoth were discovered on the newly exposed riverbed of the Danube in northern Bulgaria, after the river plunged to record lows. The Danube also runs through Croatia, where receding water has revealed the skeleton of a cargo ship called the Fulton, which was transporting coal down the river when it sank in 1937. And in Serbia, the shrunken river has exposed the remains of a sunken Nazi warship. This summer, Europe has been roiled by a succession of extreme, record-breaking heat waves, which scientists are clear have been made more intense by the human-driven climate crisis. Not only has the hot, dry weather primed the land for the destructive wildfires sweeping through the continent, but it's also putting immense pressure on its water sources. 📸: Djordje Kojadinovic/Reuters; Lyuboslav Yordanov/Slivo pole municipality/Reuters; Antonio Bronic/Reuters; Kuba Stezycki/Reuters
