Take human-originated baneful climate change : climate deniers don't deny that it could exist, merely that if and when it emerges, it will be a quick job for Batman , Spiderman or Captain America to clear up.
Nobody who makes a living solving problems (and let's see , that includes all politicians, all business people, all experts & professionals, all generals, church leaders, on and on) ever denies that problems (their very bread and butter) don't exist.
Far from it -- they are far more likely to see problems where none exist (widespread satanic cults eating our babies anyone ?) or over-exaggerate those that do exist (just as police chiefs always seem to see a growing crime wave just before proposed budget cuts.)
The only thing that most deny is the problems can't be solved or solved relatively easily.
I use that weasel word 'relatively' because expert-problem-solvers-for-money always walk a thin line.
So their pitch to clients has always to be something like this : "your problem is worse than you thought (boo) but it is solvable (hurray) but it is going to cost you some money and time (boo) , but not a whole lot of time and money."
The key word is 'solvable' - lets leave it to the courts to resolve why too much time and too much cost and and too little success emerged from so many of such promises.
Solvable is a post birth of science term , because you still see relatively few religious leaders guaranteeing success : its all "God's ( or the gods') will be done".
So while scientists today appear to be on the side of the angels on combatting baneful climate change (with climate deniers the spawn of the devil) , we must pony up and admit the deniers are sustained intellectually by scientists - not by pre-science thought like that from the world's ancient religions .
That is why this newsletter will attack scientists far more than climate deniers, in my effort to help awake the world to possibly unstoppable climate change....
