A lot of hysteria has been whipped up about the sea level rises due to global warming and melting glaciers. Media articles and documentaries showed us vivid computer mock-ups of flooded Manhattan and Florida while Global Warming activist were trotting out endless predictions of doom. Here are just some samples from our favourite alarmists to refresh your memory:
Global sea levels could rise by more than 20 feet (7m) with the loss of shelf ice in Greenland and Antarctica, devastating coastal areas worldwide.
Al Gore, Inconvenient Truth
Australia’s own chief alarmist more than triples Gore:
Picture an eight-storey building by the beach, then imagine waves washing over its roof. That’s what a 25m rise looks like.
Robyn Williams of ABC Australia quadripples Flannery:
Andrew Bolt: I ask you, Robyn, 100 metres in the next century…do you really think that?
Robyn Williams: It is possible, yes.
Obviously all these guys are lunatics who are far out of step with the alleged scientific consensus they like to promote. UN IPCC predicts sea level rises of between 18cm and 59cm by 2100. Hardly the eight story building from planet Flannery. But never mind, enterprising Tim has books to sell.
But wait, it gets even better! A team of scientists from UK, Germany, USA and Netherlands has discovered that that glaciers survived for hundreds of thousands of years during an extraordinary era when crocodiles roamed the Arctic and the tropical Atlantic Ocean was as warm as human blood:
Professor Thomas Wagner, of Newcastle University, says: “Speculation about whether large ice caps could have formed during short periods of the Earth’s warmest interval has a long history in geology and climate research, but there has never been final conclusive evidence. Our research from tropical marine sediments provides strong evidence that large ice sheets indeed did exist for short periods of the Cretaceous, despite the fact that the world was a much hotter place than it is today, or is likely to be in the near future’,
Today, the Antarctic ice cap stores enough water to raise sea level by about 60 metres if the whole mass melted and flowed back into the ocean. But the new results are consistent with independent evidence that sea level fell by about 25-40 metres at this time. Sea level is known to fall as water is removed from the oceans to build continental ice-sheets and to rise as ice melts and returns to the sea.
Dr André Bornemann, who led the research at Scripps Institute of Oceanography, University of California, and who has since moved to Leipzig University, Germany, says it is not clear where such a large mass of ice could have existed when the Earth was so hot or how ice growth could have started. ‘This study demonstrates that even these super-warm climates were not warm enough to always prevent ice growth.
“However, paradoxically past greenhouse climates may actually have aided ice growth by increasing the amount of moisture in the atmosphere and creating more winter snowfall at high elevations and high latitudes,’ he said.
So here we have it: scientists agree it will be terrible, we are going to die, sell that beach front now, head for the hills… and finally the catastrophe is cancelled. By the time we are finished with the Global Warming scare, the phrase “scientific prediction” will be synonymous with clairvoyance, Tarot and quackery. Scientists themselves will have the reputation on par with snake oil salesmen. As usual, a small minority of loud activist will spoil it for everyone.
