Global Warming for the dumbasses.

[Selatius]

For instance, show the historic levels of carbon dioxide in the atmosphere for the last 400,000 years. Anybody who is a skeptic of human-induced global warming would be hard pressed to find anything outside of humans as the culprit for almost doubling the CO2 concentration in the atmosphere in the last couple centuries.



Now this one indicates the increasing concentration of carbon dioxide in the atmosphere on a much shorter timeframe. Recordings have been taken since the late 1950s until today. If you notice, a very similar graph was featured in Al Gore's Inconvenient Truth.



Now, according to the USGS, volcanoes account from between 130 to 230 million tonnes of CO2 added to the atmosphere each year. Humans add a whopping 27 billion tonnes of CO2 to the atmosphere each year, far far outstripping anything volcanoes could do in an average year.

Compare the numbers visually:
130,000,000 tonnes/year by volcanoes vs. 27,000,000,000 tonnes/year by humans

You'd need to add another 8,000 volcanoes to the surface of earth in order to match the amount of CO2 output emitted by humans.

1. you can always go to

"junk science.com" for the Rights opinion! I'VE HEARD THIS PUSHED ON FAUX AND KNOW THAT THIS IS "DUBYAS" RESEARCH BLOG.
We will have to wait for a new administration before anything is done. but for those of us who care about this planet we can send a message at the ballot box.
Seriously though if you want to see a bunch of double talk go to this link and see the
stupid replies with out dated info. not one mention of the on going ice cores that go back for 650,000 years of co2 findings.
please help to expose this joker!

2. Face it, people on the whole don't care here

They are too involved in "campaigning" to care and skeptics are too much into denial for ideological or "economic" reasons. Only if you frame this in a political slant will people on the whole here really care from what I've seen. Information like this should be on the front page, but alas, it never is. That speaks volumes to me. And the Internet is supposed to be the one medium that takes on TV to bring education and truth? Well, the people have to want that first, I guess.
