What is Climate Change?

It most certainly is not about whether climate is changing because it always is. It is not about whether CO2 is increasing, because obviously it is. It is not about whether the increase in CO2 alone, will lead to some warming: it should. The debate is simply over the matter of how much warming the increase in CO2 can lead to, and the connection of this warming to the disastrous natural catastrophes that appear increasingly frequent in their occurence.
