Nobody is denying the fact of climate change. Changes over time ever since the Earth was formed. Sometimes it is less benign than it is now, other times it is a world-wide paradise with warm temperatures and ice-free oceans everywhere.
However, the consensus about what constitutes an “ideal” climate has still not been defined. Is it “warm everywhere”, is it “cold everywhere”, and what defines “warm” or “cold”?
And that is only the first part of the controversy, determining what the “right” climate should be. The other part, is what CAUSES climate to change? Some rather energetic types have claimed on the basis of some computer model that may or may not have been properly programmed, that activities of humanity constitute the one and sole source of any changes that cause global climate change/warming/cooling. And yet, this claim is backed up with nothing more than some vague assertion based on shaky “science” that has never been demonstrated to be reproduced in any laboratory in the world.
