This has been tossed around here before, the way one
leans politically SEEMS to directly determine one's
opinion on this subject. Congradulations Barry,
you and DK form a group of 2 maybe 10,
hope there is not more

Nah, members of both parties and almost all scientists have come around to believing the data. There are a few still left, including Calamity Jan,
who hope that people are not affecting the Earth and effecting change.
Kinda like believing the world is flat because that is as far as I can see.

I am not really sure we are saying much different-------the only controversy, it seems to me, boils down to "can man do anything about it that will
really change anything". What I hear from even the most strident is "YES, we can effect the outcome by maybe 1 to 3%. I ask, "is it worth it for
such meager possible results"???
I don't think so------the cost is just too much.

For what it's worth. There was a program on Nova the other day titled "Beneath the Antarctic Ice", or something like that. I'm a sucker for such
things and watched it to the end.
The scientists down there were studying core samples of the sediment below the ice shields. They concluded that Antarctic continent was hot and humid
during the Pleistocene Age just 15 million years ago. Knowing how much ice the continent now holds they figured that that much ice melting would raise
sea level by about 21 feet. Currently some of the big ice shields have broken off but the landmass ice is still pretty intact. By comparing that warm
spell with our current rising water temps they concluded that we will reach those conditions in 100-200 years. It's my understanding that the current
mild raises in sea level is mainly due to the ice melt in Greenland and glacier melt around the poles.
I agree with Barry that doing much about it may be too expensive. But it's a cost/benefit sort of thing. As the sea level starts to effect Manhattan
people will look at things differently. It's not an overnight fix. I keep shaking my head in disbelief over the new car ads on tv: 48mpg, 42mpg. Who
would have believed it possible back in the 60's. Those who like to say "it can't be done" usually mean "I don't want it to be done".

Great discussion! Yes sand moves but where we see it connect to rock islands is still an easy visual of little or no change over our life time. The
palapas on the Concepcion beaches have been just inches above the sea level ever since anyone has been going there. They still are.

but then again many that argue against man-made global change claim Earth has only been around 6 million years or so. Seems like they get their news
from BS Mountain.

WELL I am the OP
but I guess I will say some thing. we have had several ice ages where the poles have melted, it was caused by natural
things happening , not man made
but its my understnding what we are doing now is pushing the envelope to happen sooner than what the natural order should be, we are pushing of carbon
dioxide at an alarming rate, yes there are other factors, but this tops the list

good reading, and this is not from the Right or Left
