✓According to a new study, the fire regimes in the Arctic are changing rapidly, with zombie fires becoming more frequent
✓Fires occurring in the once-frozen tundra are also becoming frequent.
✓The fires in the Arctic spreading to areas which were formerly fire-resistant is a more worrying feature.
✓The reason for this anomaly is that temperatures in winter and spring were warmer than usual during 2019-20.
✓The fires and record temperatures have the potential of turning the carbon sink into a carbon source and increasing global warming.
✓Peatlands do not regrow quickly after a fire, so the carbon released is permanently lost to the atmosphere.
✓As peatlands release more carbon, global warming will increase which will thaw more peat and cause more wildfires.
✓Arctic fires will affect the global climate over the long term.
