Five out of six US wildfires are caused by people, says study

Some of the blazes were accidental, and as people travel more the areas at risk are increasing.

A new study blames people for triggering five out of every six wildfires in the United States and tripling the length of the wildfire season, reports the Daily Mail Online.

Even as climate change worsens the nation’s fire season – making it longer and easier to burn more acres – researchers say human activities play an even bigger role.

Scientists looking at fire data from 1992 to 2012 found that 84 percent of all U.S. wildfires were started by people, either by accident or on purpose.

Human-caused blazes only burned 44 percent of the total acres.
University of Colorado fire ecologist Jennifer Balch found that human-sparked fires increased the fire season from 46 days to 154 days.

The study appears in Monday’s journal Proceedings of the National Academy of Sciences.

‘People are moving more and more into natural wild areas and essentially providing ignition for wildfires,’ said lead author Jennifer Balch, a fire ecologist at the University of Colorado.

    Reblogged this on Climatism and commented:
    Nothing to see here. It’s global warming aka climate change aka climate disruption.
    Every natural disaster is caused by CO2. Period. (Even if CO2 is like kryptonite to fire.)

    And some aren’t classified as human caused but probably were. The Waldo Canyon and Black Forest fires for example.

    Fire ecology:
    ‘Campaigns in the United States have historically molded public opinion to believe that wildfires are always harmful to nature. This view is based on the outdated belief that ecosystems progress toward an equilibrium and that any disturbance, such as fire, disrupts the harmony of nature. More recent ecological research has shown, however, that fire is an integral component in the function and biodiversity of many natural habitats, and that the organisms within these communities have adapted to withstand, and even to exploit, natural wildfire.’

    On the other hand there can be too much of a ‘good thing’.

  4. E.M.Smith says:

    Several species in the US West, including at least one pine tree, have evolved to sprout their seeds after fire. Chemicals in smoke residue can be purchased to facilitate their propagation.

    You don’t evolve such things in the absence of fire.

    THE biggest contributor to massive fires out west has been a generation of fire suppression building up huge fuel loads. Then the notion the fire season was ever 45 days is just nuts. They used to burn until the next seasonal rains came. I smell a dodgy “study”.

    Fire-activated Seed

    Perhaps the most amazing fire adaptation is that some species actually require fire for their seeds to sprout. Some plants, such as the lodgepole pine, Eucalyptus, and Banksia, have serotinous cones or fruits that are completely sealed with resin. These cones/fruits can only open to release their seeds after the heat of a fire has physically melted the resin. Other species, including a number of shrubs and annual plants, require the chemical signals from smoke and charred plant matter to break seed dormancy. Some of these plants will only sprout in the presence of such chemicals and can remain buried in the soil seed bank for decades until a wildfire awakens them.

    Not so amazing is it? Trees may not want to give life to competitors for sunlight, water etc. right next to them, but if they know they’re in a fire that’s a different situation.

    And what evidence do these “psientists” provide to support this statement?
