Spain
burns as global temperatures

Spain burns as global temperatures rise. The Spanish city of
Valencia sits under a blanket of ash, as two converging fires
continue to devour the eastern coast of the country. Since the blaze
ignited last week, more than 45,000 hectares of land have been
destroyed, forcing upwards of 2,000 people to flee their homes.
The
fires, which have not yet been controlled, are the worst the country
has seen in more than a decade, and began as scorching temperatures
made tinder of the earth. According to the Spanish environmental
ministry one of the fires appears to have been started accidentally
by workers outside the city, and the other was caused by an
agricultural burn that got out of hand.
Lone
houses stand atop hillsides ringed in flames. Charred stumps smolder
in place of towering pines. The countryside chokes on air thick with
smoke. These images of destruction are the work of not only fire, but
also severe drought, which has become an issue of growing concern in
Spain and elsewhere in Europe. This year, Spain suffered its worst
drought in 70 years, when it received less than 30 percent of normal
rainfall. Since the start of the year, ten major forest fires have
ravaged landscapes throughout the country, laying ruin to forests and
agricultural tracts.
What’s
occurring in Spain is part of an alarming global trend. Worldwide as
the mercury climbs, fires have increased in not only frequency but
also in magnitude and deadliness. Over the past few years, fires have
consumed an estimated 350 to 450 million hectares each year, which is
equivalent to setting the whole of India ablaze. Of further concern
is research indicating that fires are not only the result of a
changing climate, but that they are exacerbating overall warming.
When forests burn they release carbon dioxide into the atmosphere,
thereby contributing to the conditions that are raising temperatures
and altering precipitation patterns.
Fires
are a natural and important feature of environmental cycles, but they
are commonly misused in deforestation and agricultural management.
While burning land can help improve soil quality and slash and burn,
or swidden, regimes are often ecologically sustaining, many of the
industrial-scale fires in South America and Southeast Asia have
devastated local biodiversity and caused soil erosion and nutrient
losses. Moreover, they’ve pumped millions of tons of carbon into
the atmosphere. A study published in Nature in 2002 found that the
giant burns in Borneo – where corporations have replaced one of the
world’s most varied landscapes with uniform palm oil plantations –
spewed as much carbon dioxide into the air as the entire planet’s
biosphere removes in a year.
While
Spain’s fire is devastating, its impact is but a fraction of the
havoc caused by the blazes searing the American West. There,
scientists say oppressive heat, droughts and uncontrollable flames
are the new normal of summer. In March, the Intergovernmental Panel
on Climate Change released a report on extreme weather and disasters,
warning that unprecedented droughts, heat waves and floods are in
store for the planet. This week, the report’s lead author, Chris
Field of the Carnegie Institution and Stanford University, said in a
statement: “It’s really dramatic how many of the patterns that
we’ve talked about as the expression of the extremes are hitting
the U.S. right now.”
Commenting
on the season’s disasters, Princeton University geosciences and
international affairs professor Michael Oppenheimer said: “What
we’re seeing really is a window into what global warming really
looks like. It looks like heat. It looks like fires. It looks like
this kind of environmental disaster.”
