> People might have been wrong about the exact date at which it would happen, but you should not let the exactitude of the date distract you.

Herbert W. Armstrong predicted that 1936 would be doomsday, and then that 1943 would be doomsday after 1936 came and went, and then that 1972 would be doomsday after 1943 came and went, and then that 1975 would be doomsday after 1972 came and went. How would you rebut that sentence if he said it in 1973 or 1974? Or if Harold Camping, who did basically exactly the same thing, said it? Why wouldn't that rebuttal apply equally to your use of it?

> Some people speculate that the arctic ice is a sort of heat shield. It makes some sense intuitively: all that white ice reflects a lot of heat back up.

But isn't the reason that the ice is at the poles that hardly any of the Sun's heat gets there?

I don’t know the numbers, the thought experiment on the last point:

Imagine that without ice the ambient temperature is 5 degrees C. And that the area being ice rather than dark colored rock causes a drop of about 10 degrees C.

So the ambient temperature in the area is under 0. But as it melts for reasons then this cooling effects disappears and now the thing is basically gone forever.

Not commenting too much on the actual theory but you could easily imagine an ecosystem disappearing due to these kinds of changes

We aren't/weren't trending towards the doomsday mentioned in your examples in any measurable way. By contrast, climate trends are well-documented.
