Siberia is currently experiencing a record-breaking heatwave, with temperatures exceeding 38 degrees centigrade, the highest temperatures ever recorded north of the Arctic circle. It's something scientists say would have been almost impossible without human-caused climate change. The Russian region's temperatures were more than five degrees higher than average between January and June of this year. The Arctic is believed to be warming twice as fast as the global average.
