All very well Cossomby, but Foxy said Nth America was covered, I think
she said miles thick in ice at 5c below current which has to mean
something like 10 to 15 deg C.
Now Nth America includes Mexico.
She made no statement that her NA meant just northern Canada.

The only explanation can be that ice melted at a different temperature
at that time.

Dear Bazz,

I have resolved it several times.
You simply can't comprehend the point that is being made.
Try reading Cossomby's explanation, perhaps that will
help. As I've stated earlier - even small
fluctuations in temperature can have dire climate consequences
globally. I'm not stating anything else - but you
can make whatever you will out of it. That's your
prerogative.

Thats right Foxy, just brush it off.

like evolutionary lies the warmist pretend the lies in their text book never existed and move on with their next fantasy. Anyone looking at predictions over the warmist/coolest, climate changers could not take them seriously. Still billions more will be wasted mainly of tax payers money.

Bazz's comment is specious nonsense. The Pleistocene glaciations of Nth America (and Europe) are so well researched and the information is so publically available, that it's not necessary to specify, when referring to the Nth American ice-cap, that it didn't cover Mexico! We don't need to specify when talking about the Great Barrier Reef, that it doesn't extend to Lake Eyre!

There comes a point when "smart" postings just reveal, in Stephen Fry's words "General Ignorance."

OK Cossomby, so I am ignorant, then enlighten me as to why the ice
does not melt at temperatures only 5c below current temperatures ?
