Apparently you don't understand that AGW does not depend on any data. It's a given consequence of increasing atmospheric GHG concentrations. Which are a given consequence of fossil fuel burning.
So the question is not if it is happening. The question is given the dynamics of more energy here on earth, when will higher climactic temperatures restore energy balance?
Ahh I see so you are free to simply make up any thing you want that furthers your supposed theory. No evidence needed, no data, no facts, no science, just fabricate it from whole cloth and then present it as if it were true.
Do you need data to accept gravity? Momentum? Inertia? Do you have to have a textbook to heat water in your microwave?
Burning fossil fuels increases the concentration of atmospheric GHG concentrations. That increasingly restricts outgoing long wave radiation. The energy that cannot leave into space must warm the earth. It will until the surface temperatures restore energy balance. Eighth grade physics.
Yes. Science requires data that is measurable. Otherwise you could just as easily say that you adhere to the Earth because some god sucks you to the dirt. See how that works. Science is based on OBSERVATION AND MEASUREMENT.
If you can't do either you are dealing with religion bucko.
