Global warming and sea level rises

It is very depressing to report this but here goes. The Guardian has published an article about sea level rises and global warming entitled, "Sea level rise doubles in 150 years". Here are some sobering exerpts:

Global warming is doubling the rate of sea level rise around the world, but attempts to stop it by cutting back on greenhouse gas emissions are likely to be futile, leading researchers will warn today.

The oceans will rise nearly half a metre by the end of the century, forcing coastlines back by hundreds of metres, the researchers claim. Scientists believe the acceleration is caused mainly by the surge in greenhouse gas emissions produced by the development of industry and introduction of fossil fuel burning.

Today's warning comes from US researchers at Rutgers University in New Jersey who analysed cores drilled from different sites along the eastern seaboard. By drilling down 500 metres through layers of different sediments and using chemical dating techniques, the scientists were able to work out where beaches and dry land were over the past 100m years.

The analysis showed that during the past 5,000 years, sea levels rose at a rate of around 1mm each year, caused largely by the residual melting of icesheets from the previous ice age. But in the past 150 years, data from tide gauges and satellites show sea levels are rising at 2mm a year.

"The main thing that has happened since the 19th century and the beginning of the modern observation has been the widespread increase in fossil fuel use and more greenhouse gases," said Professor Kenneth Miller, who led the study. "We can say the increase we're seeing is much higher than we've seen in the immediate past and it is due to humans."

According to Prof Miller, there is little chance of slowing the rising tide caused by global warming. "There's not much one can do about sea level rise. It's clear that even if we strictly obeyed the Kyoto accord, it's still going to continue to warm. Personally, I don't think we're going to affect CO2 emissions enough to make a difference, no matter what we do. The Bush administration should stop asking whether temperatures are globally rising and admit the scientific fact that they are, but then turn the question around politically and say: 'We can't really do anything about this on any kind of cost basis at all'," he said.

Of course what is really futile is the idea that George Bush is going to admit the scientific fact that temperatures are rising. I don't know whether the man is simply out of touch with reality or truly evil or both.
