Over the weekend an unexplained wildfire outbreak erupted across the Asturias and Cantabria regions of Northern Spain. In total, more than 100 blazes flared as 60 mile-per-hour winds and freakishly warm temperatures in the upper 60s to lower 70s (Fahrenheit — 15 to 20 degrees Celsius) spread across Spain’s northern coastal provinces.

More than 200 firefighters responded to the strange outbreak — one all-too-certainly linked to record warm global temperatures in the range of 1.06 C above 1880s averages. Fortunately, there are currently no reports of injuries or loss of property or life. Just an odd and somewhat terrifying mass wildfire eruption occurring in typically damp North Spain at a time near the Winter Solstice.
Another Abnormal Winter Wildfire Event
Though the cause of these fires has yet to be officially determined, temperatures in the range of 9-18 degrees Fahrenheit (5-10 C) above average and very strong winds — gusting up to 60 miles per hour — likely contributed to this anomalous winter wildfire outbreak. This warm air flow was pulled northward along the eastern edge of a powerful Atlantic weather pattern that, through most of Fall and Winter, has been hurling strong storms into Iceland, coastal France, the United Kingdom, and Scandinavia. These warm winds gained extreme intensity on Saturday and Sunday and likely sparked and fanned the wildfires (in much the same manner that Santa Anna winds risk wildfires in California).

It is not usual at all for wildfires to occur during Winter anywhere in Spain, especially not along the northern coastal regions where cool, wet weather tends to prevail as December transitions into January. But this year the typical rainfall pattern has been interspersed with warm, windy periods and comes at the end of a long, much hotter than normal year. A heat that has almost certainly contributed to a fire year that, for Spain, has resulted in the burning of more acres during 2015 than for all of the previous two years combined.
As with other recent large Winter wildfire outbreaks, the influence of a human-forced warming of the global climate system is writ large. Winter wildfire outbreaks, especially in the Northern Hemisphere, are becoming more frequent — with some major winter wildfire outbreaks even extending to regions near or above the Arctic Circle. Fires that are upshots to an overall extension of the fire season combined with a much greater frequency of wildfire outbreak. It’s trend that comes both from a larger warming of the Earth’s climate system. And not only does the added heat itself fuel a higher frequency of wildfire outbreak, it also increases drought intensity and the speed of drought onset — which generates a compounding factor for increasing wildfire frequency.
Major news media sources reporting on these incidents have yet to make this all-too-obvious link. And, given continued sparse analysis on human forced climate change as a whole, it’s questionable that they ever will.
