El Niño Weather Drives Worst Start to Wildfire Year
El niño weather is adding risk to a wildfire year that has already started at record pace, with more than 150 million hectares burned in the first four months of this year. The burned area was nearly the size of Alaska and roughly double the seasonal average for the same period.
That early burn total has already overwhelmed fire crews in Argentina, Chile and Japan, while historic blazes have also swept the US and Southeast Asia. Theodore Keeping, an extreme weather and climate researcher at Imperial College London, said: "This rapid start, in combination with the forecast El Niño means that we’re looking at a particularly severe year,".
Argentina, Chile and Japan
Argentina, Chile and Japan have already faced early season fires that stretched fire crews beyond normal levels. The scale of the burn so far has left a wide fire front across several regions, rather than a single national emergency.
The US and Southeast Asia have also seen historic blazes this year. That pattern puts pressure on local crews at the same time that the broader fire season is still in its early months.
Heat Records And Sea Ice
The fire surge has arrived alongside a run of extreme weather signals. New heat records were set this year in Australia, Greenland, France and the US Southwest, while Spain and Brazil witnessed historic rainfall.
Scientists also pointed to sea ice in the Northern Hemisphere at the lowest recorded level for this time of year, and oceans approaching record-high temperatures according to data from the University of Maine’s Climate Change Institute. Those conditions sit on top of heat and drought that have already driven the wildfire start.
Food And Energy Pressure
Heat waves are likely to put further pressure on agricultural systems and global supply chains for food. Scientists also said higher cooling demand could compound the energy shock from the Iran war.
For people in fire-prone regions, the immediate problem is not just a large burn area on a map. It is a longer stretch of extreme weather entering a season that has already run well ahead of normal, with El Niño still expected to add more strain.
