In response to StalkingButler's comment:
T he mismatch between rising greenhouse-gas emissions and not-rising temperatures is among the biggest puzzles in climate science just now. It does not mean global warming is a delusion. Flat though they are, temperatures in the first decade of the 21st century remain almost 1°C above their level in the first decade of the 20th.
No one is saying that things haven't gotten warmer, the issue is why.
Here's a couple of more points to consider.
1) Given that greenhouse gasses are the cause of warming, we're still putting more and more of it into the atmosphere, and temperatures stopped rising for over fifteen years, it means that there is another force that is exerting a cooling on the earth that is the exact opposite of the warming caused by greenhouse gasses. So, for one to still believe that AGW theory is valid one must now identify this new mysterious force and explain it's inexplicable behavior.
2) The earth has been warming for a lot longer than there has been internal combustion engines throwing CO2 into the air. In fact, we've been in a warming phase since the end of the little ice age in the middle ages. The question now becomes, what was causing the earth to warm during those centuries?
None of your points disproves the global warming theory.
There could be yet another explanation:
Scientists have observed some cyclical warming and cooling of the Earth.
The fact that temperatures have plateaued and not fallen could mean that the normal warming/cooling cycles have been interrupted by greenhouse gases and that we should be in a cooling cycle. The effects of pollution have interrupted that cycle and absent those effects we would be a few degrees cooler.
That would be consistent with both observed cyclical temperatures and the fact that recent temperatures have neither risen nor fallen.
Could be, but doubtful.
Look, it is silly to postulate what is going on here based on a couple of decades of data, and a handful of measurements.
Note I am not saying that we should do nothing. what I am suggesting is that:
We use the government means (taxation, regulation) sparingly in addressing a yet to be substantiated problem.
To the extent that human activity is responsible, I might point out that we live here, and are not simply intergallactical parasites passing through and sapping the life out of the Earth. We need to be careful to consider our needs as well.
