Over the past 30 years, temperatures in the Arctic have been creeping
up, rising half a degree Celsius with attendant increases in glacial
melting and decreases in sea ice. Experts predict that at current
levels of greenhouse gases--carbon dioxide alone is at 375 parts per
million--the earth may warm by as much as five degrees Celsius,
matching conditions roughly 130,000 years ago. Now a refined climate
model is predicting, among other things, sea level rises of as much as
20 feet, according to research results published today in the journal Science.
All of this stuff is just getting scarier and scarier.
