America Is Burning – Is This the New Normal?
B. McPherson
The US fire season has opened with conflagrations in over
100 places. New Mexico is suffering its biggest fire yet. Colorado pine forests
have been hit hard. A dry winter combined with high winds, high temperatures,
steep slopes and lightning strikes have combined to make for explosive
conditions.
The biggest fire currently burning in Colorado is the High
Park. It erupted from a lightning strike and spread over 8000 acres in one day.
Currently it has charred 60 square miles of forest. The New Mexico fire has
spread over 42 square miles as of Monday.
Last year saw massive fires in many parts of the American
West. The wildfire in Texas resulted in losses of billions of dollars and
damage to thousands of acres of land. With good record keeping, some troubling
trends are starting to emerge. The temperature is up, not much, but it is
significant. The snow pack is diminishing and melting earlier. With changing
weather patterns, more lightning strikes increase the chances of fire. Increased
human presence in wooded areas is also a factor in increasing risk.
“A University of Arizona report from 2006 found that large forest fires occurred more frequently in the Western United States since the mid-1980s as spring temperatures increased, snow melted earlier and summers got hotter, and that the fire season has grown.” The Atlantic
Katharine Hayhoe, co author of Climate change and disruptions to global fire activity published in
the June edition of Ecosphere, describes
how she and her team have attempted to use global data and climate change
models to predict the trends of large fires in the future. There is uncertainty
about the near future, but the long view shows an increasing number of
significant fires in the middle and upper latitudes and a slight decrease in
the tropics.
Yup, we've made catastrophic changes to the Earth and it is coming back to bite us - Now if we can just get the lawmakers and politicians to acknowledge that we're in deep trouble . . . But all they seem to care about is continuing to rake in the spoils . . .
