European Data Journalism: “Since 1971, the share of Europe that experiences high or higher weather risk has risen from 20% to almost 40%. But there are big differences between countries. Portugal, Spain, Greece and Italy come up every year when we talk about major forest fires. You don’t have to look far back to remember catastrophes such as the fire in Rhodes, Greece, last July, that displaced 30,000 people. Or the Pedrógão Grande fire in 2017, in Portugal, that killed 66 people. The Mediterranean is a hot spot for climate change, and a hot spot for forest fires. An increasing number of European countries are experiencing very high or extreme forest fire risk. This is a new problem for some of them. In recent years, forest fires have also become more severe in central, eastern and northern European countries. 2018 was a particularly bad year for Sweden. Sweden experienced very high fire weather risk, on average, in 49% of its territory that year, and extreme risk, the highest level, in 14% of its territory. This was a record for the last five decades. That same year, a record number of hectares burned across the country, far more than had burned in any year during the previous decade. Europe now has twice as much territory at very high or extreme fire weather risk as it did in 1971: 40 percent, up from 20 percent. This means that populations that were not previously at high risk – or at all – are now at high risk of enduring a wildfire. This index, fire weather index, measures the weather conditions that enable a fire to spread. It incorporates humidity, wind, temperature and precipitation, but does not include other very important variables such as vegetation. To know the real fire danger, fire weather risk is only one part: “Part of it depends on the weather, part of it depends on the fuel and its flammability, which also depends on its moisture content,” says Carlo Buontempo, Director of the Copernicus Climate Change Service (C3S).”
