The prediction is the sea level will rise about 3 feet.
"CapNemo" has been going to global warming questions and copying a statement pooh-poohing the threat. His statement is misleading and incorrect.
He says it’s only increased by 1 degree (F) in 125 years. Actually, it’s increased by twice that. If you look at the link below, the area in red is 1.1 degree (C) which converts to 2 degrees (F). He says, “The average temperature in Antarctica is 109 degrees below zero.” If you go to his source, that’s the number for the MINIMUM temperature, not the average. Then he says, “Back in the '70s all the hype was about global COOLING”. I was around then. I don’t remember any hype. And if you go to his source, it says, “The theory never had strong scientific support”.
The truth is that those 2 degrees are HUGE in the scale of average weather change. But the real problem is the speed of change and that it's accelerating.
Scientists are predicting a temp 4 to 8 degree (F) increase over the next 75 years. “This may not sound like a great deal, but just a fraction of a degree can have huge implications on the climate, with very noticeable consequences." (http://www.channel4.com/science/microsi ... cting.html
The link between CO2 and global warming is undisputed at this time. The amount of CO2 in the atmosphere has increased by more than 50% over the last 115 years (250 to 381 ppm, http://awesomenature.tribe.net/thread/f ... 6c08031c65
). In the last 30 years, it increased at a rate 30 times faster than at any period during the last 800,000 years. In other words, this change is totally unprecedented. (http://awesomenature.tribe.net/thread/f ... 6c08031c65
). What else is totally unprecedented about the last 115 years? Industrialization and the population explosion. Duh. This is not rocket science; it is simple arithmetic!
"... the good news is that, within the foreseeable future, Maine residents will be able to stop banking their foundations and to store their down parkas and snow blowers in the barn permanently. The bad news is that a lot of those barns will be underwater" (http://awesomenature.tribe.net/thread/f ... 6c08031c65
If global warming wasn't a real threat, why have 178 nations ratified the Kyoto Protocol to limit CO2 emissions? Why are the US and Australia the only two holdouts among the industrialized nations? (http://environment.about.com/od/kyotopr ... ocol_2.htm
CapNemo’s statement reminds me about the frog in the pot on the stove that doesn’t move as the water gradually gets hotter and hotter. From this seemingly insignificant 2 degree change, we’ve already seen enormous consequences. (http://www.davidsuzuki.org/Climate_Change/Impacts/
) How much hotter does it have to get for some people to wake up and face the music? And in the meantime, while you’re pondering all of this, be sure to check the dates on people’s references. Things are changing so rapidly that older information is no longer useful.
