The chart correlates quite nicely with James Hansen's global temperature "data". The peak in 1998 temperatures is similar to Obama's peak after he won the election. The other two peaks correlate with another couple of warm years after that.
Any idiot who can see global warming since 1998 in Hansen's data should just as easily see an INCREASE in global warming rhetoric from Obama, as well. Therefore, I totally reject the conclusions from this idiot.
