I don't think there is any question that the climate has changed over the last few decades. At issue is whether (a) it's manmade, (b) it can be undone, (c) it can be made better by regulation, and (d) improvements, such as they are, can be adequately measured over a reasonable time window.
DUmmies think that there's a continuous causal relationship between "shit man does" and "climate change," which can't be true simply because NOTHING works that way in real life. I don't mistrust liberal morons for what they THINK about the climate. I mistrust them because they have the gall to think they can DO anything about it and can be certain that whatever they spend to do it will have an impact. That is the height of arrogance and is unscientific and not economic in the least.
The day a DUmmy can provide actual proof that climate change is anthropogenic without linking to reports they haven't read and can't understand is the day I will take them seriously.
