VOLCANOES PLAYED PIVOTAL ROLE IN ANCIENT ICE AGE, MASS EXTINCTION

Climatus interruptus ping.

What’s it all about, algae? Just when I was getting into that algae extinction thing.

[Yo-Yo]

Then, 450 million years ago, the eruptions stopped. But the Appalachians continued weathering, and atmospheric carbon levels plummeted. The Earth swung from a hothouse to an icehouse.

See? If we stop driving our SUVs, we'll trigger another ice age.

I'd normally say *DUH?* but, many folks poopoo the idea that volcanoes and other Earthly emissions play a major role in Earth's past, present and future.

If they had a better knowledge of these effects, the misconception of man-made global warming would be farther from their minds.

[Constitutions Grandchild]

I worked with a geologist for 20 years who said 15 years ago that all the man-made carbon producing activity from prior to through all recorded history couldn't match what comes out of one volcano. He called it a bogus line of scare tactics years ago, and I've always trusted his judgment. He is an extremely educated individual and possesses all the right judgment I could hope for in all areas of his life, i.e. he's not a nut.

It took the scientists 400 million years until the eve of the Copenhagen conference to find this out.

This is just so much BS. They are still trying to claim CO2 causes global warming and throwing in the cooling bit in order to explain what is happening now. The reason Volcanic eruptions causes cooling is because a large layer of debris is floating in the atmosphere(Krakatoa springs to mind). This is with huge eruptions of course. I doubt if they caused an ice age, the sun and the earth's rotation caused it.

Science in this country is dead.

[wolfcreek]

They would obviously rather pay for something that doesn’t exist rather then read a couple of books.

Gullible Fools.

[vpintheak]

Impossible! Apart from the timeline, it was humans from the future going back in time. They revved the engines of their SUV’s, first causing global warming, and then global cooling! Don’t these people know anything! Volcanoes! HA!

[NorCoGOP]

C'mon...we all KNOW it was Gore Magnon man that caused globull warming back then...

The debate is over.

There. I win.

See? That's how the Goracle plays it....

[Cletus.D.Yokel]

Perhaps ironically, these volcanoes first caused global warming -- by releasing massive amounts of carbon dioxide into the atmosphere.

Another Kool-Aid drinker...

What matters here is that there are mechanisms which are NOT in any contemporary Global Climate Model, ones which have profound consequences on Earth's climate.

The Global Climate Models are totally bogus until they can accurately repeat from a given set of initial conditions the last five hundred million years of Earth's history. There are prodigious negative pathways which are simply not incorporated. The Science is NOT in. And until it is, the Global Climate Models are classic Garbage In Garbage Out.

You have heard this from the Suntrade Institute, not from Barack Obama, not from Harvard University, not from the Brookings Instituion, and not from the CFR.

- the dumber you are the more they will manipulate you.

What a bunch of crap. Mean CO2 was 4200, 15 times preindustrial CO2. If carbon drives the system, the Ordovician should have had a super-tropical climate.

I don't suppose it occurred to these geniuses that Gondwana drifting over the South Pole might have a little something to do with the glaciation???

I will give them one point. When it got cold in the latter Ordovician CO2 levels fell. Like they always do when it gets cold. But once again they are suckers for the correlation equals causation fallacy.

[Swiss]

I suspect any climate change lasting more than a decade was caused more by the Sun than events on Earth.

There is only one sure way of knowing. Send all the global warming experts to the surface of the Sun to check CO2 levels, collect rocks and explore volcanic activity there. I say a mission this critical for our future would need the best Nobel Price winners leading it. Obama, Gore, and Carter.

... many folks poopoo the idea that volcanoes and other Earthly emissions play a major role in Earth's past, present and future.

Volcanoes and other earthly emissions undoubtedly play a roll in the earth's mean temperature, but contrary to this author's tired old line, it's just not C02 that does it. Probably has more to do with lots of particulate matter being thrown way high into the atmosphere and reflecting solar radiation as opposed to "greenhouse gasses". Rising C02 concentrations have been shown over and over in ice core data to follow rising temperature, not the other way around.....

[aruanan]

Perhaps ironically, these volcanoes first caused global warming -- by releasing massive amounts of carbon dioxide into the atmosphere.

Virtually all the warming due to CO2 comes from the first 100-120ppm. Below 200 ppm there is no plant growth. Three, four, five times the amount of CO2 we have currently would have a relatively small effect on atmospheric temperature.

Your “How The Earth Got Its Gas” link is bad.

Jeez. I’m not a scientist, but I read a lot, online and off, and I figured out what volcanic ash can do if the eruption is big enough.

Al Gore should live so long....
