In the USA, climate change under RCP8.5 could increase the burned area by 60-80% by 2049  and the number of fires with an area >50 km2 by 300-400% by 2070 . In montane forests, climate change under RCP8.5 increases the risk of fire-facilitated conversion of ~7% of forest to non-forest by 2050 . In California, climate change under a scenario of a 4℃ temperature increase could double fire frequency in some areas , but emission reductions that limit the temperature increase to ~2ºC could keep this from increasing .
