What's the optimal length for a piece of string? If they don't know then why say that 3 tons of it is a bit much to fit in your pocket?

"Optimal " is irrelevant . Ice-age is not good for Woolworths fresh food , tropical swamp in central Oz keeps Coles prices up ,up.
Goldilocks had it right. Polar bears don't.

A new,correction, another Ice-Age is inevitable no matter what the puny minds of the sheele think. it'll definitely freeze up the scientist bandwagon.

The clowns at the IPCC, & the fraudsters who have hitched their get rich schemes to their wagon are really starting to panic now. They have access to the real science, & know damn well that the reduction in sunspots will lead to cooling for many decades. The only question is will the poms have ice festivals on the frozen Themes river again, & for how long.

The useful idiots will tell us global warming is real, or that nuclear power is the end of the earth, all we can hope is that the cool comes quickly enough to avoid us getting locked into even more stupid expenditure such as windmills & electric cars.

Hasbeen Quote "The useful idiots will tell us global warming is real"

That name was the scam but it did not take long for people to see it was not getting warmer so they changed it to climate change which encompasses everything and they now think they can get away with that.

500 polar bears can't be wrong. Tour the Arctic while the ice is still visible , it's too late for the barrier reef.

nicknamenick,
They're as right or wrong as the mammoths were & the sabretooth tigers & the Neanderthals although of the latter there are still some throwbacks here'n there.
