Trends in global fire occurrence and fire modelling

Global burned area by wildfires is declining, which mainly originates from Northern Africa. However, the satellite records of ~20 years are still too short and inaccurate to state if this decline in global fire occurrence is robust. Also for the future, we cannot robustely predict how fire occurrence will change. Although climate warming and drying will cause more fire-prone weather conditions, actual fire occurrence also depends on human activities and vegetation conditions. Current global fire models cannot well represent these effects on fire (Figure).

Warmer springs lead to reduced plant growth in summer and autumn

"Earlier, warmer springs — a consequence of climate change — have lengthened the northern growing season and have increased plant productivity earlier in the year. However, there is some evidence that there may be both beneficial and adverse lagged effects on plant growth later in the year. (We analysed) satellite measurements of vegetation greenness, and report regional differences in beneficial and adverse lagged effects on plant growth across the Northern Hemisphere. (...) The accumulation of seasonal water deficits may result in regional adverse lagged effects in plant growth in response to warmer springs" (Nature 562)
