Wildfires Emit As Much C02 As Vehicles Do In An Entire Year

Alexandria, VA...Large wildfires in the western United States can pump as much carbon dioxide into the atmosphere in just a few weeks as cars do in those areas in an entire year, a new study suggests. As forest fires devour trees and other plants, they release the carbon stored in the vegetation into the atmosphere. Scientists at the National Center for Atmospheric Research (NCAR) and the University of California used satellite observations of fires and a computer model to estimate just how much carbon dioxide is released based on the amount of vegetation that is burned. The results of the study are detailed in the online journal Carbon Balance and Management.

      Wonder how much much carbon dioxide is emitted in a day by any of the various volcanoes erupting every year?

      Then again, how much carbon dioxide is emitted in a day by all the humans and other respirating mammals roaming the earth?

      Kind of makes the futility of driving a crappy electric car seem pretty inconsequential,....doesn't it?

I assume no one is surprised to learn that burning vegetation releases CO2. Or that a huge wildfire will release a lot of CO2.

An important point to remember is that vegetation will regrow in the areas burned. Brush will return in just a few years; trees will take longer, but it is still time measured in a few decades, not centuries. Thus, the CO2 released by these wildfires will be withdrawn from the atmosphere within a few years (brush and grasses) to a few decades (trees). In contrast, the CO2 released by burning fossil fuels will never be returned to crude oil and coal. So burning oil and coal irreversibly adds to the CO2 burden of the atmosphere; wildfires do not.

Similarly, breathing releases CO2 derived from vegetation, even it by way of a beef steak. So that does not irreversibly increase the CO2 burden of the atmosphere either.

There are some things besides fossil fuel burning that add irreversibly to the CO2 burden. Volcano eruption is one but not one we can control. Clearing grasslands or forests to build cities and roads usually takes that vegetation out of the carbon cycle forever, so that adds to the problem. Melting of the permafrost will release a huge amount of CO2 essentially forever and that is possibly out of our control since we seem unable to halt the global warming that will cause the permafrost to melt.

Bottom Line: Wildfires create a temporary increase in atmospheric CO2; burning fossil fuels causes a permanent increase. It's a mistake to use wildfires as an excuse for not limiting fossil fuel burning.

One more nerdy point: CO2 released by burning fossil fuels can be used, of course, to grow a tree. So the trees that regrow in Butte county will be comprised in part of carbon that was once crude oil. To the extent that happens it just leaves some CO2 from the current wildfire in the atmosphere where it contributes to global warming. Regrowing (or growing) vegetation only causes a net decrease in CO2 if more (denser) vegetation grows as CO2 levels in the atmosphere increase. This has been studied and more CO2 does, in fact, cause faster vegetation growth (up to a point anyway). But this effect is not strong enough to overcome the continuing increase in atmospheric CO2 caused by burning fossil fuels.

    You got some funny science.
    CO2 is CO2,

    CO2 emitted by mammals breathing is the same as CO2 caused by burning fossil fuels, Abiotic fuels, Volcanoes and Wildfire emissions. The only difference between them is the companion chemicals emitted from each CO2 contributor. The heavier components, such as Carbon Monoxide will return to the ground, Hydro Carbon will dissemble via evaporation and dilution.
    But when all is said and done, CO2 is one and the same and there will always be a component of CO2 in our atmosphere.
    That's just the way the manufacturer built it.

    If the climate alarmists were correct, we'd all be dead already.
