Scientists are starting to admit how bad the situation really is (the following is all in quotes):

"Two-Degree Temperature Rise Could Flood Wide Areas of Planet, Study Says"

by Margaret Munro

"A team of geophysicists is warning that the massive polar ice sheets are even more vulnerable to global warming than previously believed, and could trigger a sea level rise of six to nine metres.

 

"The scientists from Princeton and Harvard universities say that just two degrees Celsius of global warming, which is now widely expected to occur in coming decades, could be enough to commit the planet to inundation.

 

"The time to avoid disastrous outcomes may run out sooner than expected," says Princeton's Michael Oppenheimer.

"He is co-author of a ominous new report on what happened the last time global temperatures rose a couple of degrees - the Greenland and West Antarctic ice sheets melted away so extensively that sea level rose between 6.6 and 9.4 metres.

"If emissions of greenhouse gases are not reduced soon, they scientists say the planet could be committed to comparable melting, which might be unstoppable.

"They say low-lying regions around the world could be inundated by more than a metre of sea level rise this century, followed by many more metres in coming centuries. Low-lying areas like Bangladesh and Florida would be hard hit, and Canadian communities from Tuktoyaktuk to Vancouver to Charlottetown could all expect to see waters rise. A one-metre rise in sea level would immediately affect 145 million people around the world.

"The geophysicists' report in the journal Nature Thursday is a new - and much more "startling," according to a commentary accompanying the report - assessment of what occurred the last time polar temperatures were three to five degrees Celsius warmer than today. The so-called "last interglacial stage" 125,000 years ago is considered an analogue or guide to what might happen if global warming continues on its current path.

"The new assessment is based on sea level indicators such as coral and beach records as well as changes to Earth's gravity and surface as massive ice sheets melted away. It concludes that during the last interglacial, global sea level peaked more than 6.6 metres higher than today and may have risen 9.4 metres. That is higher than previous estimates, and indicates much of the Greenland and Antarctic ice sheets melted away.

"The "disconcerting message" is that the planet's response to 1.5-2 degree C of global warming could be an increase in sea level of seven to nine metres, Peter Clark at Oregon State University writes in a commentary."

Harvard. The school that graduated obama and is hiding his records. I have no reason to trust them.

The arctic ice receeds aproximately every 70 years. Right now, the ice cap of antartica is growing.

If all the ice of the arctic were to melt, the sea would not rise. The ice is floating on ocean.

Just want you and everyone else to know I, of course, respect your right to your opinion.  But if I thought there was a grave danger and didn't mention it, I would be remiss.  Thank you for your comment.

I do not know what to believe anymore..

Yes, there is grave danger of icemelt resulting in ocean level rise and some islands and low lands going under.

Question is whether it is cyclical. This is where I am a bit confused.. If it was cyclical (multi-generational cycles), we would not know if it is that, as there is not as much recorded history as might be germane in this case.

So, sans some real hard analysis it is difficult to subscribe to the notion that the 2-degree rise is indeed going to happen.

What hurts the credibility of scientists is the suppression of evidence to the contrary. The email-gate.  It makes all other work a bit suspect. "Goal-driven" science is very bad when it ignores contrary evidence.  It is as bad as "goal-driven" journalism.  Hence my skepticism.

I would prefer to err on the side of caution... Greening the earth can be done at the grassroot levels and with better consumer behavior. Carbon taxing and cap and trade are fake assets with pie-in-the-sky goals; I am not into such complexity when we can do the simple thing of planting trees and cutting less trees for Christmas.

Meanwhile, if you bought a real potted tree for Christmas, please plant it. If you have not bought a cut tree, do not buy one. Thanks..

I am also not sure what to believe anymore but there are a lot of things like land fill that we can do. Alex we are not all cookie cutters and on this board you can post whatever you want except for Pro Obama posts and I don't see you doing this.
We are not Obots and can debate politely.  Thanks for posting this article its very interesting.
