Why I Am a Global Warming Skeptic

If the High Priest of global warming catastrophism is not willing to defend his proposition in public debate with qualified opponents — or better yet, put his money where his mouth is — then why should I take his claims seriously?

Oh, wait — his comrades did debate the subject once, and lost badly. Maybe he has cause to be cautious.

  1. Having recently inerviewed the leader of the Climate Change Expedition 2008, Earl de Blonville, who claims the tipping point is behind us and who supplied his evidence (soon to be on You Tube and Australian networks), I had to use the NASA press release, as reported by Reuters, to show that a most cautious institution is close to the same conclusion as de Blonville.

    To add to that is that Australia is about to lose its agriculture (no rain – in some areas a 10 year drought). The drought clouds and rain were described to perfection in Steinbeck’s, Grapes of Wrath. Here we have purple clouds overhead for days and then big fat drops of rain that pit the dust for aout thirty seconds.

    A record melt of Arctic summer sea ice this month may be a sign that global warming is reaching a critical trigger point that could accelerate the northern thaw, some scientists say.
    “The reason so much (of the Arctic ice) went suddenly is that it is hitting a tipping point that we have been warning about for the past few years,” James Hansen, director of NASA’s Goddard Institute for Space Studies, told Reuters.
    The Arctic summer sea ice shrank by more than 20 per cent below the previous 2005 record low in mid-September to 4.13 million sq km, according to a 30-year satellite record. It has now frozen out to 4.2 million sq km.
    The idea of climate tipping points – like a see-saw that suddenly flips over when enough weight gets onto one side – is controversial because it is little understood and dismissed by some as scaremongering about runaway effects.
    The polar thaw may herald a self-sustaining acceleration that could threaten indigenous peoples and creatures such as polar bears – as Arctic sea ice shrinks, the darker ocean soaks up ever more heat than reflective snow and ice.
    In Germany, the Potsdam Institute for Climate Impact Research says Arctic sea ice has “already tipped”.
    Among potential “tipping elements” that are still stable, it lists on its website a melt of Siberian permafrost, a slowdown of the Gulf Stream and disruptions to the Indian monsoon.
    “I’d say we are reaching a tipping point or are past it for the ice. This is a strong indication that there is an amplifying mechanism here,” said Paal Prestrud of the Centre for International Climate and Environmental Research in Oslo.
    “But that’s more or less speculation. There isn’t scientific documentation other than the observations,” he said.
    Many experts now reckon Arctic ice may disappear in summer before mid-century, decades before earlier forecasts.
