Just wanted to comment on the rising sea levels. I spent from May 2004 to August 2008 in the Republic of the Marshall Islands, Kwajalein Atoll. The sea level change there in my last two years was very signifcant. Entire tree-lines were wiped out and homes had to be pushed back futher from shore. It got so bad at times that you had to watch where you were going via boat because entire trees were floating in the lagoon and would do major damage if not sink your boat if you hit them.
Sadly, they say too, that the Marshall Islands will be gone in 50 to 100 years.
