Earth’s sea levels may rise 25 meters by 4000 AD despite CO2 freeze

LONDON - A new study on the effects of climate change on melting ice sheets has indicated that even if scientists could freeze-frame the atmospheric carbon dioxide (CO2) as it is today, sea levels would still rise by 25 meters by 4000 AD.
According to a report in New Scientist, Eelco Rohling of the UK National Oceanography Centre at the University of Southampton and colleagues conducted the study.
They reconstructed sea level fluctuations over the last 520,000 years and compared this to global climate and carbon dioxide levels data for the same period.
They found a tight coupling between carbon dioxide and sea level rise.
Based on this relationship, the team calculated that if the amount of carbon dioxide in the atmosphere were fixed at current levels, temperature rises over the next couple of millennia would eventually drive sea levels up by 25 meters.
The team emphasizes that the rise would not happen overnight or even over the next century.
Two studies published last year suggested that there is a limit to how fast the water can rise.
According to one, sea levels could rise by approximately 1.3 meters by 2100. The other set the upper limit at 2 meters. (ANI)
I live in the 'mountains' of FL. I'm about 55 feet above sea level! ;D

Well my 45' radio tower tops out about 75'ASL so I will just have to use ground wave....
A little rise in sea level, that's nothing. Scientists have developed their "best ever" estimate an when our Sun will go super nova and destroy the entire solar system. I don't want to start a panic.I'll bring the marshmallows!We only have 4 and a half BILLION years left.
I don't thing you have anything to worry about for this lifetime....except BHO's eldercare!!!

There are beds of SEA shells in Vermont. More alarmist BS.Heck there are sea shells in the Rockies, I think it had something to do with the great flood.

Not active. Got a handy/talkie, VX7R I key up every now and then. I've an 857D still in the box from March with and LDG tuner, antennaes, wire, etc...waiting for me to have time to install. Maybe next week. Got a 1011D in wrapping paper that's never been used...and a 10M wire for it....I just need a microphone and a way to bring the voltage up slow for a while to keep from blowing caps.
