Love it when it snows

millercarbon, I totally agree with you but you could put it in a nicer way.
There are many very intelligent people who are totally ignorant on the subject of climate science. The problem is that most of them have no idea how ignorant they are. I can say this as I was a Biology major at the University of Vermont and specialized in Ecology. 
mahgister, all you have to do is look closely at the past starting about 4.5 million years ago. Look at weather conditions and atmospheric composition through time as earth evolved and decide for yourself. You have to read the transcript:)

Thanks for your balance reply and polite one...

I am not a biologist at all, then ignorant for all these matters...But looking at various climatic geological scales will only reveal the regular periodical instabilities, or homeostasis of earth and the cosmic exterior influences...

The fact that human activities accelerate or contribute to reverse some trends is the crux of the matter...I dont think it is possible to humans now only by themselves to revert earth cycles, but to act in unity without increasing the worst to comes is the goal, not going on with past used economic concepts that applied no more to what will comes ...

Lesson from the past in human life or in earth life is only this one: Nothing is perfectly stable... But we can and must consciously adjust ourselves, especially now it is possible for the first times in human history...

Negation of changes, pursuit of the same economic habits had no more sense...

An ignorant chap who read that could be led to believe that the actual end of the world was at stake. What Hanson was saying was the tipping point of being able to keep rising temps within a 1ºC rise over a certain time frame was at stake.

One must be wary about how info is presented.

All the best,

Hmmm, what to do?  I think I’ll go with the opposite of whatever Frank says.
