NEW YORK: Caught in a "vicious" circle of global warming, the polar

speeding up causing the warmest summer in 400 years, an yet to be
released NASA report said.

So, they're saying it was this warm 400 years ago? How'd that happen?

What caused the last ice age?

What caused the end of the last ice age?

How about the ice age before that? And the one before that?

Well, there's certainly no substance abuse in your contribution.

I can dumb it down a bit for the merkans. Notice the order of magnitude
differences between 40 years and 400 years, and 40,000 years and
400,000 years.

Of course, since the bible told them the Earth is only 6000 years old,
further extrapolation via nuclear and fossil proxies, engineering and
exponential notation, and empirical evidence is unproductive.
