There are numerous ways to falsify AGW. I've listed several before. Let's see:
1) Show that humans have not produced significant amounts of greenhouse gases.
2) Show that the greenhouse effect is not real - that greenhouse gases do not trap infrared
3) Show that the AMOUNT of infrared that greenhouse gases trap is grossly inadequate to have caused the observed warming
4) Show that the incoming and outgoing radiation at the ToA are equal - that there is no imbalance
5) Show that the world's temperature has not increased significantly since the start of the Industrial Revolution.
6) Show that there is no overlap between the frequencies of IR absorbed by CO2 and that radiated by the warmed Earth
7) Show that the frequencies of IR absorbed by CO2 are also absorbed by water vapor and thus there's simply no energy left for the CO2 to affect
Proving ANY of these points would falsify AGW. And I bet you've heard almost every one of these presented here by one denier or another. So why hasn't anyone picked up the $10G?
Because just saying it don't make it so. They need to support their contention with BETTER evidence and BETTER reason than is being used by the mainstream scientists who all accept AGW. And they haven't. And it's pretty close to a perfect guarantee that they haven't because they can't.
WOW! The ol' prove something does NOT exist!
More proof that the AGW cult is not about science, but promotion of a religion.
Of all the carbon emitted into the atmosphere each year, 210 billion tons are from natural sources, and only 6.3 billion tons are from man's activity. Man's burning of fossil fuel, therefore only accounts for 3 percent of total emissions of CO2.
People are never told that the most powerful greenhouse gases by orders of magnitude is water vapor and clouds. When only human emitted CO2 is considered, less than one percent of the greenhouse gas potential comes from human activity. Yet, all the global warming is supposed to be attributed to it. Water vapor plays a huge role in keeping the earth warm; 70 times more powerful than the CO2 emitted by human activity. When clouds are added, CO2 becomes even less important. However, clouds not only trap heat, low elevation clouds also reflect much of the incoming solar radiation, so the sun's heat never reaches the earth's surface which cools the earth. It is this mechanism that a growing number of scientists believe is one of the primary mechanisms warming and cooling the earth.
