Large areas of the Arctic are ablaze as incidents of wildfires reach unprecedented levels, satellite images show. According to the EU Copernicus Atmospheric Monitoring Service (CAMS), these Arctic wildfires have emitted as much carbon dioxide in June as produced by Sweden in an entire year! In Alaska, summer temperatures reached 32 degree Celsius against the average. In parts of Siberia, June temperatures were almost 10 degrees higher than the long-term average. Globally, past four years have been the hottest ever recorded, according to NASA.
