The risk of catastrophic wildfires is growing around the world as climate change fuels sizzling, tinder-dry conditions, increasing the need for fire-prone countries to adopt preventative measures, scientists warned Wednesday.
Smart, proactive policies - such as setting fires at the end of rainy periods to reduce blazes during hot, dry spells - could help reduce the danger, they said inHere's why wildfires are a growing threat - and how the world can better adapt to changing risks:Why are wildfire threats growing so significantly?
Australia, the U.S. West Coast, Canada and parts of southern Europe, among other places, have long been known for their seasonal wildfires. But fire risk is now surging as well in places from Syria to Siberia and India, scientists say. That includes fires like an 1851 blaze in Australia's Victoria state that devastated an area the size of England, said Andrew Sullivan, a bushfire expert at the Commonwealth Scientific and Industrial Research Organisation in Canberra.
"It's not normal to have fires in rainforests," said Glynis Humphrey, a plant conservation specialist at the University of Cape Town and a report author.Portugal's fire risk started to rise more than two decades ago as migration out of the countryside to the cities left more land unattended, allowing flammable undergrowth to accumulate.
