What about the last four years. How about 12? How about 18 years? 20? 40? 100? Why 16? You brainwashed, paranoid, dimwit deniers are a joke. Given that CO2 has gone up about 35% over the last 150 years from the burning of fossil fuels and we know CO2 is a dominant greenhouse gas, how could it be that temps should NOT go up?
Anytime you see liberals running around screaming about a crisis, take the other side of the argument. I just saved all of you a lot of time.
Science In Action - The Futurecurrents CO2 Global Warming Test First, be sitting in a comfortable chair when participating in this test. Second, take 20 deep breaths fully exhaling rapidly in succession. Now, do you notice the lightheadedness that you feel and the increase in body warmth? That is due to the massive amount of CO2 that you've just exhaled that is now surrounding your body. Whala! Proof CO2 is a greenhouse gas.
Oh that's right CO2 is THE dominant greenhouse gas. My bad. "Water vapour is a "reactive" GHG with a short atmospheric lifetime of about 1 week. If you pump out a whole load of extra water vapour it won't stay in the atmosphere; it would condense as rain/snow and we'd be back to where we started. If you sucked the atmosphere dry of moisture, more would evaporate from the oceans. The balance is dynamic of course: humidity of the air varies by place and time, but its a stable balance. In contrast, CO2 has a long lifetime (actually calculating a single "lifetime" for it doesn't work; but a given CO2 pulse such as we're supplying now will hang around for.. ohh... a century or more). It doesn't rain out (amusing factoid: the surface temperature of the deep interior Antarctica in winter can be colder than the freezing point of CO2; but this doesn't lead to CO2 snow (sadly, it would be fun) because the freezing point is lower because of the lower pressure because its higher up). So if you put in extra CO2 the climate warms a bit; because of this move WV evaporates (it doesn't have to, but just about all models show that the relative humidity tends to be about constant; so if you heat the atmos that means that the absolute humidity will increase). This in turn warms the atmosphere warms up a bit more; so more water gets evaporates. This is a positive feedback but a limited one: the increments (if you think of it that way) get smaller not larger so there is no runaway GH effect. http://mustelid.blogspot.com/2005/01/water-vapour-is-not-dominant.html deniers are like the people that deny evolution. Morons.
oh you mean the one released by seabeds in enough quantity to be known to sink ships that methane or the gas between your 2 ears?
Yup. I mean seabeds, permafrost and cow farts, not the gas in my head. Big problem there is these gasses are not included in most projections due to uncertainty about them. They will definitely accelerate warming and if they release it's game over for half of the life on the planet. They have in the past when there only natural cycles and now the amounts stored are even higher.
