Some people believe we're actually not looking at global warming coming up but rather re-entry to a mini ice age. See "Vostok Ice Core" samples out of Russia and what people infer from that.

I'm not endorsing this viewpoint btw, just trying to very very briefly explain it to you.

No single web page I can point you to I'm afraid. My climate folder got clobbered and I haven't had a chance to go and snag all the pages that were in it again. Plus they were mostly from alternative sources.

I understand (better than most!) that my position is contrary to the prevailing wisdom but then I'm the right age to be a curmudgeon about all this:

- the sun is what gives our planet warmth

- its long term cycle can be very accurately measured by sunspot activity

- we're currently entering a grand solar minimum

- this will trigger the mini ice age

- previous example: the Maunder Minimum which triggered the last mini ice age

The Maunder Minimum would be a good thing to search for.

They may have been making a coy reference to nuclear winter (https://en.wikipedia.org/wiki/Nuclear_winter)
