Cool. An admission if complete ignorance.

I just read Hansen et al. article published in 1981 in
Science (for other reasons that the present discussion).
It predicts a 2.5-4.5 °C warming for 21st century according

"predicts" - 1 - total 9

to fossil fuel proportion in energy use. It says precisely that
a 2°C global warming would be enough for a 5°C warming

"would be" = 2, total 11

of the West Antarctica Ice Sheet, whose melting could be
rapid (”requiring a century or less and causing a sea level

rise of 5 to 6m” that “would flood 25% of Louisiana and
Florida”).

I read your post as a joke; meteorology is
uncertain by definition. If you can't handle
uncertainty, you shouldn't be in the business.

Further, let me make it perfectly clear that I do
not personally expect or predict the "complete
collapse of the West Antarctica Ice Sheet" or
ANYTHING CLOSE TO THAT over the next century.

Meteorology means uncertainly. I you can't handle it,
get out of the business.

To be perfectly clear, I myself don't expect the "complete
collapse of the West Antarctica Ice Sheet" in the
next 1000 years.

A Clive Cussler book last year had that same plot -- collapsing the
ice sheet to affect the word's rotation. Did you steal the plot?

How are you coming on getting those meteorology credentials together
to show us all you really *are* a meteorologist? All we need is your
licensing and/or registration numbers, you know...

....still waiting ;-)

Is that why you're not really "in the business" - the "uncertainty" of
your credentials "in the business"?

lol!

He ain't a meteorologist, but rather a crook.

Nah. Just a narcissistic, sociopathic liar. And definitely not a
meteorologist.
