Lomborg on Climate Hysteria

Excellent review of what the IPCC report actually said by Bjorn Lomborg on Comment is Free. While it does highlight that mankind is contributing to global warming this was already understood. The main changes are, as Lomborg describes, the following:

"The report did, however, contain two surprising facts. Both went unmentioned in most reports. First, the world's scientists have re-jigged their estimates about how much sea levels will rise. In the 1980s, America's Environmental Protection Agency expected oceans to rise by several metres by 2100. By the 1990s, the IPCC was expecting a 67-centimetre rise. Six years ago, it anticipated ocean levels would be 48.5 centimeters higher than they are currently. In this year's report, the estimated rise is 38.5 centimeters on average.


The report also revealed the improbability of another Gore scenario: that global warming could make the Gulf Stream shut down, turning Europe into a new Siberia. The IPCC simply and tersely tells us that this scenario - also vividly depicted in the Hollywood movie The Day After Tomorrow - is considered "very unlikely". Moreover, even if the Gulf Stream were to weaken over the century, this would be good, as there would be less net warming over land areas.


A 38.5cm rise in the ocean's levels is a problem, but by no means will it bring down civilisation. Last century sea levels rose by half that amount without most of us even noticing."
