The Climate Show #12: twisters, Olaf on ozone, and Google in the sun

[youtube]udadT7eDWYQ[/youtube]

Ozone is the centrepiece of our show this week, with Dr Olaf Morgenstern of NIWA’s Central Otago atmospheric science lab (celebrating its 50th birthday at the moment) explaining the ins and outs of the ozone holes north and south, and their impacts on the climate system. Plus tornadoes, heatwaves, UN negotiations at an impasse, more melting in the Arctic, airships, see-through solar cells and Google’s solar towers. No John Cook this time — he’s been too busy launching his book (good luck with that John!).

Educating Richard (or not)

If ever you wanted a demonstration of the strange version of reality occupied by those that would deny the need for action on climate change, then Richard Treadgold — he of the oddly one-sided climate conversation — provides a perfect example in his recent attempt to respond to a post of mine. You may remember that Treadgold challenged the PM’s science adviser to come up with evidence for human-caused climate change (amongst other things), and that I took the bait — delivering carefully referenced replies to each of Treadgold’s demands. And I noted in my conclusion:

When offered evidence, Treadgold adopts the Nelson defence. He can’t see it, so it doesn’t exist. But he’s been playing this game for so long that his demands and protestations cut no ice. Being blind to the evidence is not scepticism, it’s denial, and that’s an estate Treadgold has occupied for a very long time.

Treadgold’s riposte demonstrates my point nicely — and at great length. I leave it as an exercise for the reader to enumerate the many ways in which his application of the wrong end of a telescope to a blind eye serves him ill, but I will note that in the land of the Climate Clueless™ it’s apparently acceptable to get numbers wrong, fail to read references, ignore inconvenient data and misrepresent facts.

Brash in pocket

Confirmation that new ACT Party leader Don Brash still considers himself a climate sceptic comes in an interview he gave to arch-libertarian commentator Lindsay Perigo shortly before he launched his takeover putsch (starts as about 24:10 on the Youtube video). Brash happily confirms his scepticism, saying:

“I don’t believe the case has been established that human activity is warming the climate.”

He continues:

“We know that there was a medieval warm period that was much warmer than the globe is now, and we know the Roman period was quite a lot warmer than it is now.”

He also claims that a “very close friend”, “one of Australia’s top physicists” believes “the whole thing’s a con”.

It only takes Brash about a minute to effectively disown the entire scientific establishment (apart from his physicist friend – I wonder who that is?). ACT’s new leader needs to have his feet held to the fire on this. Why should we take his policy prescription seriously, when he is so dismissive of reality in the case of climate change? Perhaps the prime minister’s science advisor, Sir Peter Gluckman, could invite Brash in for a briefing. But perhaps the chink of Alan Gibbs’ loose change is deafening him to the facts…

Climate: The Counter Consensus

ClimateThis review of Bob Carter’s latest book, by Dr James Renwick, Principal Scientist at NIWA’s Climate Variability & Change group, was first published in the March newsletter of the Geoscience Society of New Zealand. My thanks to Jim for permission to republish it here.

This book is a curious read, full of misinformation, straw-man arguments, and poorly-documented assertions. To become immersed in it, we must enter the through-the-looking-glass world of the “independent” scientist, where those such as myself are the ones “…who have dissembled, told half-truths, cherry-picked their data, fantastically exaggerated, and suppressed the circulation of better science” (Prefatory Essay, p. 19). Meanwhile, the ideas put forward by Prof. Carter are portrayed as representing a balanced appraisal of the issues. From where I sit, that’s the opposite of reality.

Four years on…

Today marks the fourth anniversary of the first post at Hot Topic — four years since the blog’s birth, and as my mum would say, hasn’t time flown? This birthday post is number 1,080, and it will be read by many, many more people than those first brief paragraphs announcing the book and blog. I’m not one for tootling my own trumpet (at least, not loudly), so I won’t be making great claims about how far we’ve come and how much we’ve achieved, but I will take this opportunity to muse a little on what I’ve learned. A lot, but not perhaps enough… 😉
