For Arizona and New Mexico, Climate Change Produces Winter Fires

(500 acre wildfire burns near Isleta in New Mexico on February 19th. Image source: KOAT) It’s late winter in Arizona and New Mexico. Or at least that’s what the calendar says. During this time of y…

Garry Rogers insight:

Drought alone can increase fire frequency and size.  In AZ and NM, the continuing increase of fine fuel from alien weeds adds to the drought impact.

Forest Threats Include Global Warming, Weeds, and Fire

Forest Threats Include Warming Climate, Spreading Weeds, and Increasing Wildfire

Humans have spread weeds to new habitats across Earth.  Most weed species grow well in sunny habitats typical of desert regions.  The weeds increase the quantity and continuity of fuel and they recover quickly after a fire.  Thus, they allow accidental and lightening caused fires to grow larger and become more frequent.  Anyone who follows the effects of a desert fire for a few years will see that many native plants recover too slowly to persist under the new weed-accelerated fire regime (Rogers and Steele 1980).

1901.  Cedar Mountains by G. K. GilbertThis pair of photographs from the Great Basin Desert illustrates what recurring fire can do in the desert.  (Click on the images for a larger view.)  The first photo was taken in 1901 by geologist G. K. Gilbert (USGS Photo Library).  It shows fairly even cover by the small native shrubs dominating the vegetation of the area.  In 1901 there was no travel in this area except by horseback or wagon.  Gilbert was fond of the horse, named her Sally, and included her in many of his documentary photos.

2008.  Cedar Mountains by Garry RogersThe second photo was taken in 2008 and shows that as far as the eye can see, most of the shrubs are gone.  They have been replaced by fire tolerant non-native weeds.  This area burns so frequently now that the U. S. Bureau of Land Management stewards of the land have begun burning the land themselves to help prevent surprise fires that disrupt traffic on the nearby interstate highway.

The second photo is presented below in color and larger size to give a clearer view of the extent of the barren weed/fire landscape.

Forest threats include more than just warming climate.  Some climate models predict increased forest fire occurrence as climate warms (Smithwick et al. 2013:  2).  It is likely, however, that fire prone weeds will increase.  Invasive weeds do poorly in the shade of mature trees.  As domestic livestock, loggers, and drought continue to disturb forest soils and remove the shade cast by tall trees, weeds will increase.  As has happened in lower, drier habitats we may lose many native forest species.

Congressional Climate Change Deniers

U. S. congressional representatives of major energy and development interests continue their long war on climate change. Their chief strategy, deny it, question it, deny its importance, etc.

Oil Refinery Smog

Oil Refineries Create Serious Health Problems in Davis County Utah. Contribute to Climate Change.

The Salt Lake Tribune (March 19, 2013) reports that Republican Chris Stewart, brand new Congressman from Davis County, Utah, and chairman of the House environmental subcommittee,says, “”I’m not as convinced as a lot of people are that man-made climate change is the threat they think it is,” he told The Salt Lake Tribune. “I think it is probably not as immediate as some people do.”

For his 2012 political campaign, Stewart received more than $40,000 from donors associated with the oil and gas industry (Center for Responsive Politics, CRP).  Republicans like Stewart aren’t the only ones to represent big oil.  According to CRP, Democrats that voted in favor of oil company legislation have taken money too.

Climate Change Will Increase the Intensity and Frequency of Forest Fires

In a December, 2012 report, the U. S. Forest Service describes what is coming as a result of climate change.  According to the report, the main short-term effects on the national forests will come from the increased intensity and frequency of disturbances. Continue reading
