Consider how much carbon Odumbo dumps into the atmosphere from his 747 Air Force One... for all of his (a) vacations, and (b) fund raisers. Makes the rest of us look like "carbon skin flints"..
Not water but sulfur dioxide or aluminum. This would replicate what happens during a volcanic eruption. It's been studied and may be necessary as an emergency fix in the future. It can be done fairly cheaply and with a dedicated fleet of only a half dozen or so 737's. It's called geoengineering. There are of course several problems including accidently sending the earth into even worse climate conditions and it does nothing to prevent acidification of the oceans.
Sir, you are the one that makes any intelligent conversation on this impossible, if something is shown that questions the validity of "Global Warming" or now it is "Climate Change", then the person is part of the "Fossil Fuel" Lobby, a Faux News viewer, or, not an acceptable "scientist". You have all the answers, feel good about that. Like I said before, you are convinced, so start solving it by foregoing fossil fuels, put up some solar panels and wind turbines, ride your bike and lobby for carbon taxes. Why such an urge to bash anyone that follows the scientific method? You are treating this like a religion. By the way, the man that started it all issued a paper about this, but you will surely point out that he was "tricked" and senile at the time (maybe Faux News made him do it); http://ossfoundation.us/projects/en...singer-lindzen/cosmos-myth/Cosmos_article.pdf Allow me to make one more point; people who question the validity of Global Warming (oops, sorry...I keep forgetting it's "Climate Change" now) are not advocating that we burn through fossil fuels and pollute without any regard to the environment. The billions going towards Climate Change "research" would have been much better directed to the development of LIFTR's which would provide safe, abundant, and clean energy. You, know, real science stuff.... Good luck to you, and let us know how your life is going without a car, air travel, or freely available energy. And just a suggestion, when you don't agree with someone, resorting to names really undermines your credibility. Remember, this is not a religion, and you have all the answers anyway.
So, you still don't know if CO2 is a greenhouse gas. Is that correct? Do you even know what a greenhouse gas is? I told you, first learn something about the science/subject you are arguing about and then come back.
Interesting information regarding Airplanes and the unique opportunity to study their affect after 9/11 http://www.pbs.org/wgbh/nova/space/contrail-effect.html
Is there climate change ? Yes. It has been happening since the origins of this planet. Incontrovertible. Is there global warming ? Yes. The earth has been undergoing warming and cooling cycles since the origins of this planet. Incontrovertible. Do humans play a part in this ? Yes, but the extent and degree of human interaction as a direct causal agent to climate change is not established scientific fact. CO2 and NOX emissions in the US have actually decreased dramatically in the past five years - this is primarily due to coal burning power plants being converted to run on much cleaner natural gas. Call it an unintended positive consequence to hydraulic fracking. The abundant supply of natural gas has made it economically preferred to coal to the point that utilities and private generators are willing to spend tens of millions of dollars to retrofit a plant. Imagine that - free enterprise accomplished what regulators and politicians and screaming suicidal tree huggers could not. The primary drivers of climate change referendums ( Western societies ) have very little leverage to change the most pressing and blatantly offensive human behaviors. Rain forest and jungle destruction in Central America, Africa, and Asia, and wholesale pollution from emerging market economies and Eastern European countries. Russia won't or can't change it's polluting ways, and China is only now budgeting funds to address pollution because the very workers and citizens who are fueling China's ascendency are suffering on a massively broad scale from pollution-induced health issues. IMHO, in the United States there are greater threats to our environment; 1. Our management of water resources, and 2. The management and eradication of invasive species.
