Do you have a good link to the article? The one in the Op doesn't work. It's hard to comment about it when I can't read it. 11 years isn't very long when talking about sea level though.
How does a 30-year timeframe grab you?
[i][b]Global mean temperature will likely rise at about 0.6 degrees Fahrenheit per decade and sea level at about 2.5 inches per decade over the next century. These rates are 3 to 6 times recent historical rates. (emphasis mine)
- Dr. Robert Oppenheimer, June 23rd, 1988, part of Congressional Testimony[/I][/b]
Reality (In graph below, source: NOAA):
[I][b]Notice that the rate of sea level rise is 2.8 millimeters per year (1.1 inches per decade), less than half of what Dr. Oppenheimer predicted. More importantly, notice that the rate of increase has been pretty constant, despite the fact that the carbon dioxide concentration in the atmosphere rose significantly during that same time period.[/I][/b]
Dr. O’s testimony was given at the same hearing where NASA’s Dr. James Hansen gave testimony that is historically considered to be the start of the Anthropogenic Global Warming er, ummm, “movement”.
Dr. H’s dire predictions failed just as spectacularly. We can delve into his body of work also if you so desire.
