Yes, We Have No Bahamas?

Rising Floods Of AGW Non-science

The revelations of fraud, conspiracy, incompetence, and criminal suppression of evidence that mark the collapsing card-house of the man-made global warming myth are coming so thick and fast that I'd need full time and a team of assistants to keep up with them. But a good site that brings the latest reports and headlines together in one place would be www.climategate.com. An overview more comprehensive than anything I could put together of what's been going on is also given by Marc Sheppard at American Thinker

But a side of it that I can't let pass without comment is the tales that the world has been hearing about human-induced warming melting the Antarctic ice sheet and causing sea levels to rise to an extent that will flood the lowlands and send panic-stricken survivors heading for the hills. Marc Sheppard, once again, puts the record straight here, with an account of how Norwegian scientists have drilled holes through the coastal ice shelves, measured the temperatures of the waters beneath, and found no signs of warming.

The chart below, taken from Marc's article, shows the steady rise in sea level of approximately seven inches per century that has been recorded as the world recovers from the "Little Ice Age" of the 1600s. There's absolutely nothing to suggest a sudden tenfold increase in the rate, as the IPCC has been predicting.

To make the point further, here as a longer-term reconstruction of sea level change, following the end of the last major ice age.

Taken from a piece on the same topic by Randall Hoven. Is anyone still gripped by fears of imminent doom or that humans might make any difference that matters?

It has always mystified me how--even if the computer models were remotely related to reality--a projected rise of a degree or so is supposed to melt a mass of ice half again as large as the continental USA, 16,000 feet deep in places, at an average temperature of -50oC or more. Especially bearing in mind that merely transforming ice to the liquid state requires an enormous amount of heat, without raising its temperature at all. In fact, about 90 times the heat needed to raise the same mass of water one degree. So to melt the ice sheet, you'd have to supply around half as much heat again as was needed to warm it through 50 degrees to get it to the melting point.
