Why CO2 from Volcanoes Is Definitely Not the Issue

    June 16, 2017

One of climate-change deniers’ favorites assertions to make is that it’s not us throwing all that carbon dioxide into the atmosphere — it’s those pesky volcanoes. While it’s true that volcanoes spew tons of pollutants into the air when they erupt, do they really contribute more CO2 than we do? Or even the same amount as we do? Short answer: Hell, no. Astrophysicist, science communicator and NASA columnist Ethan Siegel explains how the comparison shakes out in an article for Medium.

Irrelevant because CO2 doesn't cause warming anyway.

The moon receives the same insolation as the earth -- and in any given place, more, per 24 hours.  Why is it cold?

As do the poles. Why are they cold?

When I see ALL the jackasses who support the global warming crap start living like they believe we are killing the planet's biosphere, then I might have a tendency to believe them. So far all I see are people who want to be our new lords and masters in a new feudal re-arrangement of all nations on Earth. Until then, I will not change nor will I believe them. There has been way too much doctored data and garbage computer models used as their basis.

You mean it really is the hyperventilating over-agitated followers of the Cult of Gore that are causing all that extra CO2?

(Fermenting all that corn to make ethanol to glop up good gasoline might be part of the problem, too)

The earth's poles receive less isolation than the equator of the moon.

Yep. Incidence angle has a lot to do with atmospheric backscatter. It is part of the reason that photoelectric solar panels really become less desirable as latitude numbers go up, and even passive solar heating gets less effective. That and the changes in the hours of sunlight between winter and summer. (about 48 degrees latitude, 8 hours of sunlight in midwinter, 16 hours in midsummer).

Insolation varies, too, and not just with latitude: From https://www.wholesalesolar.com/solar-information/sun-hours-us-map

I assume that is for real...and it made me chuckle.

I like this gem:

Before getting into the numbers, though, it’s worth noting that volcanic activity is the earth’s way of getting needed carbon out of the crust and into the atmosphere in CO2. And for billions of years we believe this has been going on without resulting in the kinds of elevated CO2 levels we’re seeing now: an estimated 3.2 trillion tons, of which 870 billion tons are carbon.

==========================================================
Whoa, scriiiitch, full stop. That just isn't so. For hundreds of millions of those years, it was a LOT higher.
