🔥 Our analysis of 25 years of fire data within Canada’s intact forests landscapes (vast, unbroken forests that play many critical roles) reveals that Canada’s annual summer season is becoming slightly longer.
Fire alert data on Global Nature Watch (formerly Global Forest Watch) shows that the average fire season over the past five years is starting one week earlier and ending one week later compared to the preceding 20 years.*
As fire seasons lengthen even just by 1-2 weeks, the risks to climate, nature and people grow as well.
