Global warming is happening and mostly human caused. We can fix it.
AGW is a myth supported by those who profit from it.
Global warming is happening but we are powerless to stop it.
Humankind should be researching how to adapt to natural climate change.
We should be more concerned about an impending ice age.
Climate change is natural and inevitable.
None of the above and I'll explain in my post.
That is two statements, not one. The first is true. The second involves the residence time of GHGs in the atmosphere, and the tipping points of such things as the permafrost and Artic Clathrates.
We cannot fix what we do not yet understand. We know the residence time of CO2 is in centuries, but do not yet understand enough of how the initial amount effects the length, a few centuries, or many, of time involved. As for the rest, we simply don't know where we are on those items, period. We may be already past the tipping points, we may be centuries from them, or not be a problem at all if we reduce the amount of GHGs that we put into the atmosphere in a reasonable time. Given that we don't know yet what constitutes a reasonable time.
Kind of like running down a road in a dense fog at full speed, knowing full well that there is a bridge out over a deep canyon somewhere down the road, but since we don't know how far, it is OK just to keep the pedal to the metal.
