There are hundreds of fires all across the Arctic Circle, in Greenland, Siberia, Scandinavia and Alaska. Smoke is visible from space. The Arctic is warming twice as fast as anywhere on Earth. It is also having its worst wildfire season ever. In Alaska, there are 400 fires out of control. People say the fires are unheard of in history.
The fires could affect global warming. A scientist said: "Temperatures in the Arctic have been increasing at a much faster rate than the global average. Warmer conditions encourage fires to grow." Dry ground, lightning and strong winds are spreading the fires. The fires are releasing CO2 and killing animals.
