A lot of people have been putting two and two together and getting four thousand - somehow everything that is happening is blamed on a tiny difference that couldn't possibly be responsible.
The only way the eco-terrorists can maintain their power is to claim that they're the only ones who can see clearly what is happening and only they stand between us and total disaster. Kind of like the old shaman/medicine man thing when they made lots of wild claims and took all the credit (and power) when a couple actually happened. The eco-terrorists are also living off the rest of us while contributing nothing but confusion.
When this happens go back to basics; The only thing we know for sure is that CO2 levels are higher then they have been since we have been measuring it. Therefore, you can draw a line from that to some other things. You don't even have to stick your neck out. Like pollen counts are higher and some plants thrive. That part is a 'no-brainer' and isn't a product of any 'spin'.
