This Christian conservative says he has a phD and he has proven with two graphs

that there are stronger correlations between higher solar output, volcano eruptions and higher earth temperatures and plans to publish them for peer review.

Now correct me if I'm wrong, but hasn't that simple correlation been refuted before by the AGW community. So I'm guessing this guy is a troll, since he also believe Al Gore is a Big Brother type. He also recommended expelled by Ben Stein:

But I've heard about Volcanoes emitting some of pollution in the air, but I don't know if it's more in ppm than humans in a geography text once I think.

But I don't know how just two graphical correlations can be powerful, let alone two variables, unless the numbers are really astronomical and significant in comparison to human contribution to global warming, not to mention if humans cause more volcanic eruptions or if it was independent.

Umm I always thought that more volcanic eruptions would cause the Earth to cool down since the ash blocks out sunlight...

He must've missed that one on the way of constructing his research...so in actuality, the Volcano's would be balancing out their contribution of greenhouse gases by blocking out incoming rays with ashes.

Yes I am, but why do you try to bring up my past instead of answering the question?

If goes through the peer review process, he may have a leg to stand on.

Right now, not so much.

Now correct me if I'm wrong, but hasn't that simple correlation been refuted before by the AGW community.

In that a significant correlation cannot be found with rigorous analysis methods, yes. People have been trying since the 18th century, but a significant link has proven thus far to be elusive.

Also, he claims that solar activity has been increasing recently. Yet his own graph (correctly) shows that solar brightness has *decreased* slightly since the 1960s. Solar brightness cannot be used to explain the rapid warming observed since the 1970s. Solar brightness changes probably explain ~10% of the warming observed during the 20th century, but only before 1960.

But I've heard about Volcanoes emitting some of pollution in the air, but I don't know if it's more in ppm than humans in a geography text once I think.

Volcanoes emit on average ~0.1 billion tons of carbon (GtC) in the form of CO2 per year. Humans emit on average ~8GtC of CO2 every year, 4GtC of which linger into the next year. If volcanoes were such a significant source of atmospheric CO2, we should see the CO2 time series be significantly influenced by major volcanic eruptions.

http://www.esrl.noaa.gov/gmd/ccgg/trends/

If volcanoes were a major contributor, we should see a spike in the time series in the early 1990s from Pinatubo, and the middle 1980s from El Chichon. We see such an effect in the surface solar radiance records, caused by ash and aerosols from these eruptions, but no CO2 spike.

http://en.wikipedia.org/wiki/File:Mauna_Loa_atmospheric_transmission.png

IF anything, the Pinatubo eruption may have caused a slight temporary *decrease* in atmospheric CO2. The reason is not quite clear, but there appears to be a small dip in the CO2 record in the year after Pinatubo.

If goes through the peer review process, he may have a leg to stand on.

The first problem is that this author is obviously taking a shotgun approach to the climate change issue. The solar argument is usually used as an attempt to *discredit* the GHG argument. And so it seems very suspicious that he would include a GHG argument alongside a solar argument. Of course, the lack of quantitative support for his claim will ensure that his submission is caught by the peer review process like the spam it is.

In the short term, volcanoes induce a cooling effect, as the ash blocks sunlight. Over the long term, the only way volcanoes could be responsible for the increase in greenhouse gases is if volcanic activity had dramatically increased over the last 150 years - in which case they'd be putting out so much ash that it would at least balance out, if not overcompensate. The latter has not happened, making any case for the former pretty much discredited from the get-go.

Volcanoes eject a very large amount of C02, a green house gas, when they erupt. Plus, the ash clouds only block sunlight from hitting the surface, the sunlight still enters the earth, and most of it stays there due to the greenhouse effect.

So as a previous poster said, in the short term, volcanoes decrease SURFACE tempatures, but the total amount of heat or sunlight entering the Earth should still be the same

I don't have a clue if volcanoes eject enough CO2 to cause any sort of long term warming, but they most assuredly don't cause any sort of long term cooling..
