Andrew Bolt on "greenhouse mafia"

Herald Sun: Sneaky green mafia [17feb06]

I did not see all of last week's Four Corners program, but enough to make me a bit suspicious.

Andrew Bolt notes in the article above that the main informant on one aspect of this has questionable objectivity on the issue. Go read his article if you have not already.

One of the matters mentioned in the report that raised my suspicion was about sea level rises and "environmental refugees". See this part of the transcript:

DR BARRIE PITTOCK, CLIMATE CHANGE EXPERT: I was asked to talk about the science of climate change, the impacts and the possible adaptations. But I was expressly told not to talk about mitigation, not to talk about how you might reduce greenhouse gases.

JANINE COHEN: One of the subjects was the impact of rising sea levels. Dr Pittock says he wanted to write about how this could lead to the displacement of millions of people in the Pacific Islands and parts of Asia who might be forced to seek refuge in Australia.

DR BARRIE PITTOCK, CLIMATE CHANGE EXPERT: They don't want that highlighted because it brings in another contentious issue into what is already a contentious issue. But it is an issue. It's one of the possible consequences of global warming. And I think it should be part of the background to deciding what to do about it.

And further into the show:

KEVIN HENNESSY, CSIRO IMPACT GROUP: Certainly, environmental refugees does impact on government policy. The sort of thing that I could say as a scientist, is that with sea level rise there may be people inundated in places like Tuvalu in the Pacific. And that would be an issue that needs to be considered by government policy. But I certainly can't go beyond that as a scientist.

As I noted in a previous post here in January, the latest research indicates a rise of perhaps 30 mm in a decade, but even then the rate of sea level rise has gone up and down over the last century. Indeed, actual measurements in Tuvalu reported in 2000 (see my other post on this topic) indicated a much smaller rate over the previous 25 years of less than a mm per year, no acceleration of the rate, and that levels can also drop dramatically if there is an El Nino weather pattern.

To me, it sounds as if CSIRO scientists may have taken quite a sensationalist approach to this issue if they are talking about millions being displaced, or even Tuvalu having to be evacuated, at least over the next few decades. There should be lots of caveats added to any discussion of sea level rises and global warming.
