Definitely not settled science

A letter by Robert Munro in the Herald from Everett Washington includes the phrase:

"The climate clowns are out in full-force; their plans for your future are Orwellian."

The letter:

Proponents of global warming have written much about rising tides and temperatures, extreme climate and the untold death and destruction that will ensue should we not stop releasing carbon dioxide into the atmosphere. Further, we've been told that this is settled science; that no further discussion — nor dissent — will be tolerated. 

Given that 15,000 years ago, much of North America was under glacial ice thousands of feet thick, they got the warming part right. However, their remaining claims are dubious and better fit the classic definition of fraud: “The intentional perversion of truth in order to induce another to part with something of value or to surrender a legal right.” And far from settled, it stopped being science when they began altering data such that it produced their desired result.
A primary proponent of global warming, Michael Mann, states that: “Proof is for mathematical theorems and alcoholic beverages. It's not for science.” He further believes that proof is not necessary when you have a theory that enough people believe. The corollary to this is: Repeat a lie often enough and people start believing it.
The climate clowns are out in full-force; their plans for your future are Orwellian. It's time to get the facts! Introduce yourself to professor emeritus of geology, Don Easterbrook, Ph.D., Western Washington University, you'll be glad you did. 

He closes the letter with the link to this YouTube by Don Easterbrook:
