Nope. We have proof. Scientific, repeatable proof. To wit:
1) CO2 is a greenhouse gas. Increasing concentrations of CO2 increase heat retained. This can be proven in a high school physics lab.
2) We are increasing the concentrations of CO2 in our own atmosphere. Again, provable via simple chemistry and math; tons of coal/oil burned compared to the volume of the atmosphere.
3) Temperatures are increasing according to the predictions based on increases in greenhouse gases.
No, they don't.whilst the data fron the historical evidence shows the oposite..
You'd make a great lawyer.There is no proof that the current level of CO2 is causing change in global temperatures.
Any change in temperature could equally be the result of many other influences.
"Your honor, the evidence will show that the defendant poisoned Mr. Jones by putting polonium in his coffee. The medical examiner found fatal amounts of polonium in his blood, the defendant stood to gain significantly through his death, and five witnesses saw the defendant pouring the polonium into his coffee."
HH: "But there's NO PROOF that that polonium actually killed him! He might have just had a heart attack right before the poison took effect. Or he might have been shot. Or someone might have been about to shoot him, and that scared him to death. Or cancer. OK so they didn't find any cancer, but you know doctors. It could be ANYTHING!"
The image of rich grad students pushing an unfounded theory to keep the money pouring in, while the poor Exxon executives are powerless to stop them is a funny one indeed. I bet you even believe it......and people whose income and financial situation will benifit, have a vested interest in promoting the AGW theory.
The fact remains that greenhouse gases in our atmosphere cause more retained heat. We are increasing the concentration of greenhouse gases in the atmosphere. The temperature has increased as predicted. And no matter how much fear, uncertainty and doubt you sow, and no matter how politically correct you get to try to align with the new US administration, you cannot change those basic facts.
The reason deniers will fail in the long run is not due to rhetoric, or even scientific studies. They will fail because people in Alaska will see their towns eroding away because the pack ice is gone. They will fail because farmers will see their crops die off due to higher temperatures and droughts. They will fail because Indians will see their coastal cities flood. And at that point, the "the temperature isn't increasing! It's all lies! And even if it's happening, it's not our fault! And if it is, the changes will all be good!" rhetoric will fall flat.
