The risk of wildfire increases along with an increase in global temperatures . With 4ºC GSAT warming by 2100, wildfire frequency is projected to have a net increase of ~30% . Increased wildfire, combined with soil erosion due to deforestation, could degrade water supplies . For ecosystems with an historically low frequency of fires, a projected 4℃ global temperature rise increases the risk of fires, with potential increases in tree mortality and the conversion of extensive parts of the Amazon rainforest to drier and lower-biomass vegetation .
