By my calculation, it seems that over 80% of the members of the USA National Academy of Science have chosen not to sign this letter.

I think it is good for Democracy when a minority opinion such as that held by this relatively small cadre of biologists, anthropologists, zoologists, etc. is published.

The overwhelming paleoclimate evidence from around the globe is that the Medieval Warm Period (MWP) was synchronous, world wide and much warmer than today. So much for the it is the "warmest on record" nonsense from the warmists,. It might be the warmest ever measured by a thermometer, but no where near the warmest when measured by many other paleoclimate methods.

But the warmists and their apologists have to deny that the MWP ever happened, because it means that their religous-like belief in AGW is exposed for the steaming pile of junk science that it truly is.

Since the temperature was higher when CO2 levels were lower, then CO2 can not be the controller of Mother Earth's temperature.

The science is really that simple.

A thousand years ago, the Earth was warmer than it is today; before the social and industrial advances that have made modern people the healthiest and most prosperous in history. MWP deniers want us to believe that plant friendly, ocean cleansing and life giving CO2 is a bad thing to better advance their meglomanical desire to both boss around the developed world and further impoverish the poor while pocketing a lot of taxpayer money along the way.

If we are lucky, Mother Earth's temperature will return to those glorious levels in the past where Greenland was farmed by the Vikings and my ancestors, the Polynesian people, made important voyages of discovery across the Pacific in search of cooler temperatures. Siberia will become the world's food basket and the Sahara might bloom again as a warmer world brings more rainfall there.

Taxing carbon is not the answer to the ever changing climate.There is only one answer to changes in climate that has ever worked for humanity.

That is adaptation.

Fraudulent claims, using faked "Hockey Sticks", openly and aggressively violating Freedom of Information requests and conspiring to squash dissenting views by corrupting the peer review process, that's the type of work that some climate scientists have done to mislead the public about the causes and affects of our ever changing climate. On top of all that comes the admission by Dr. Jones that his tricked up temperature databases can’t be reproduced because he didn’t keep the notes of how he did the manipulations.

And the warmists call this irrefutable science.

Well, here is some real irrefutable science.

The overwhelming paleoclimate evidence from around the globe is that the Medieval Warm Period (MWP) was synchronous, world wide and much warmer than today.

However, the MWP deniers will never admit the existence of the MWP because it means that their religious-like belief in AGW is exposed for the steaming pile of junk science that it truly is.

In total, climate change is complex and not well understood.

But this part is simple.

If the world was warmer when CO2 levels were lower, CO2 cannot be the earth's temperature regulator.

A thousand years ago, the Earth was warmer than it is today; before the social and industrial advances that have made modern people the healthiest and most prosperous in history. MWP deniers want us to believe that plant friendly and life giving CO2 is a bad thing to better advance their meglomanical desire to both boss around the developed world and further impoverish the poor while pocketing a lot of taxpayer money along the way.
