Re the denialists, I think it impossible to educate them, as they wish the world to be as they want, not as it is.
There is no way to make it otherwise for them.
They will continue their denial, even after the demise of the Greenland ice sheet.
(In reality, this will happen only long after they and we are gone.)
Yet, I will continue to confront them, even though it will do no good, none whatsoever.
