Gets used here.... alot.
Arguments both for or againsts a scientific problem should be framed as defendable proofs.
We know that the top of Earth's atmosphere receives 342 watts of energy, in the form of sunlight, per square meter. Note that 107 W/m2 of this energy is reflected or scattered back into space by clouds, the atmosphere, and high-albedo features on Earth's surface. So, only 235 W/m2 (342 - 107) of energy actually make it into the atmosphere, and shines down upon us giving me women in miniskirts and the ability to grow food (both of which are....awesome)
Furthermore, we know that 67 W/m2 of the incoming energy is absorbed by the atmosphere, and another 168 W/m2 is absorbed by Earth's surface. When energy is absorbed, it raises the temperature of the substances that absorb it (the atmosphere and surface of our planet, in this case); this causes those substances to radiate away that heat in the form of IR radiation. We can all agree that these are not simply my opinions right? For those of who are are unfarmiliar, these are called facts, lets keep going.
About 390 W/m2 of IR energy starts upward from the surface, this difference being caused by longwave radiation needing an atmospheric window that does not have a lot of water vapor or gas molocules containing three or more atoms (i realize this is incomplete, i am atempting to simplify). The more of these conditions present in our atmosphere, the harder it is for longwave radiation to escape. So when we spew into the environment, and what we need to agree on is that adding vapor and GHG's to the environment increases the GW potential... right? Keep your fucking anecdotes to yourself, Using these things called facts we can see that keeping equilibrium becomes more difficult when we insist on changing the atmosphere. So don;t tell me you got two colds last year and only on this year so we are getting warmer, or that your uncle your uncles garden got frosted early thid year so we are geting colder. Or about ICEBERGS, this is an atmospheric issue, give me meaningful data about that and i will listen. Anyone who thinks that chnging the composition of our atmosphere will not result in temp change needs to back to school.
