That is because volcanoes dont pump out pure CO2. Volcanoes also release sulfur dioxide which reacts with water to produce sulfuric acid. This leads to a colling affect due to the reflective nature of sulfuric acid droplets.
Way to state the obvious, have you heard of context? Now, prove the warming effect after they go off to validate his previous statement that I was responding to. No, you can't use what he said, it's wrong. I'll tell him why right away.
Do a little research before making connections that are completely untrue.
While I appreciate that you're making note of it before posting something pointless, you need to realize your mistake and correct the error.
Yes, Volcanoes put lots of CO2 in the air and yes, it has been shown that there is a short period of cooling immediately following some of the dramatic prehistoric volcano eruptions. But, this is because of the vast amounts of ash and sulphate aerosols that are spewed into the atmosphere that block and reflect sunlight away from the troposphere. If you did your research, you'd find that after this period of cooling there were long periods of warming. The ash and sulphate aerosols settle, but the CO2 stays in the atmosphere. In fact, there is evidence that shows that the volcanic eruptions that split Greenland and Europe to create the Atlantic ocean was followed by a 222,000 year long warming period.
So close, and yet... not. If you did your research, you'd know that there is no such warming period following any of the recent volcanic activity. The reason being the gas output is insignificant, momentary, and quickly absorbed back into the system. It does not stay in the atmosphere. There's no magic CO2 layer floating up there, it circulates through and absorbs into the oceans and flora. The rate at which it does so is based on how much of it there is. When a volcano puts more out there, it gets absorbed faster. Simple physics, something the climatologists can't seem to grasp for unknown reasons.
The evidence you point to was a massive, five million year long eruption. The boom was a minor event, cooling the planet. The following five million years of magma buildup as the crust disappeared would have been all warming. The effect of CO2 is also vastly insufficient to account for it, despite being a force equal to burning every bit of fossile fuels in existence, today. The theory is that they've simply under-estimated the forcing effects and that the huge warming period was a result of those forcing effects. The problem is no such forcing effects are being observed. Recent warming trends from CO2 increases have been zip, we're actually below normal despite little volcanic activity and high solar output.
Yes, I know, the surface stations say we're really warm and the trees say we were never this warm. The trees still say we aren't this warm, they are in disagreement. All the glacial core samples say we've been much warmer, with no change in CO2 to account for it.
And what is your point about all the ice ages? I see no point being made there. The only point I see is a big desire to prove how immature you can really be.
You don't consider an ice age to be harmful to humanity? I realize it's a less immediate concern than southern Florida disappearing under the ocean in a century or two, but doesn't the absurdity of preserving this state of glaciation occur to you?
I wear shorts are thirty below, I shit you not, I've no wish to unthaw the planet. I laugh mercilessly at you reptiles that can't handle a few flakes without wearing a fur lined parka. It makes it all the more hilarious that anyone who's looked at the ice core records and seen how utterly fucked civilization is in a few thousand years would be worried by a little warming.
Edit: Right, I forgot. To the millions of idiots living in the middle of a desert, bitching about the lack of water. Fuck you.
Seriously. If I move to a desert, water a fucking lawn, and then bitch at someone else when there's a water shortage, I want someone to hunt me down and kill me. I've become too stupid to continue my existence and need removed for my own good.
