4.7 billion dollars in grant money in the U.S. alone.....
Stupidity on stupidity. The global warming 'scare' began about 1820, when Fourier pointed out that something in the atmosphere was absorbing outgoing heat. That was confirmed in 1859 when Tyndall measured the absorption of IR by the GHGs in the atmosphere. Arrhenius quantified the amount of warming that doubling the CO2 in the atmosphere would create in 1896. Keeling started measuring the CO2 in 1957 on Mauna Loa. Now there are CO2 measuring stations all over the world recording the increase.
So now you admitting 1820?
Way before there was official records, way before any way man could of done it?
Yup Judith and the rest were right.
Science totally ignores the natural variations
Lordy, what a ******* fool you are. Totally ignorant of basic science.
Why we know about the greenhouse gas effect
Our understanding of how certain atmospheric gases trap heat dates back almost 200 years to 1824 when Joseph Fourier described what we know as the greenhouse effect. Fourier, a French mathematician and physicist, asked what seems to be a simple question: why doesn’t the planet keep heating up as it receives sunlight? What is regulating our atmospheric temperature?

Joseph Fourier: bane of countless physics and engineering students.
Knowing that heated surfaces emit radiation (thermal energy), Fourier reasoned that the Earth would emit radiation absorbed by the Sun back into space – resulting in an icy planet. There must be something regulating the temperature – emitting enough thermal energy to keep the planet from freezing and overheating. Not too hot, not too cold.
Fourier’s answer to these questions is formalized in what we now call the greenhouse gas effect. From the
American Institute of Physics history of climate change page:
How does the Earth’s blanket of air impede the outgoing heat radiation? Fourier tried to explain his insight by comparing the Earth with its covering of air to a box with a glass cover. That was a well-known experiment — the box's interior warms up when sunlight enters while the heat cannot escape. This was an over simple explanation, for it is quite different physics that keeps heat inside an actual glass box, or similarly in a greenhouse. (As Fourier knew, the main effect of the glass is to keep the air, heated by contact with sun-warmed surfaces, from wafting away. The glass does also keep heat radiation from escaping, but that's less important.) Nevertheless, people took up his analogy and trapping of heat by the atmosphere eventually came to be called "the greenhouse effect.
