Drinking wine spo-dee-o-dee

Grapes.jpg According to a Reuter’s piece in the Guardian [UK], New Zealand’s wine makers are upbeat about their prospects in a warming world. A warmer climate will increase the area suitable for producing fine wine, but it may mean changes in the grapes being grown.

Higher temperatures due to global warming are expected to make cold areas of New Zealand more temperate and better suited to grape cultivation. So it’s no surprise that New Zealand wine-growers are upbeat about a future that includes climate change. “The big picture for New Zealand wine is very, very good,” said Philip Gregan, chief executive of industry body New Zealand Winegrowers.

A rather nice confirmation of the view I expressed in Hot Topic. One of the interviewees is Clive Paton of Ata Rangi, a name to conjure with in the world of NZ red wine:

Paton said the Martinborough climate is ideal for producing Pinot Noir, but a slight rise in the temperature would be enough to tip the balance. So Paton has been looking at Syrah, also known as Shiraz, getting to grips with the nuances of an alternative variety, in preparation for a potential shift. “Even if it does rise a half or one degree, it’s still going to be a great place for growing grapes,” said Paton.

Very true. Good job we have some syrah chez Hot Topic. But what if the warming is not so moderate…? The rest of the world is worried. Discovery Channel covers the second Climate Change & Wine conference, being held in Barcelona this weekend. Pancho Campos, the president of the Wine Academy of Spain, who organized the conference, also thinks we might be on to a good thing:

The French “Grand Crus” could be further threatened by the “New World” wines of Australia, California, Chile, Argentina, South Africa and New Zealand, who would have the best climatic conditions. “The countries in the southern hemisphere are next to a greater mass of water, and it is sea currents which maintain the temperature at its level,” said Campos.

[Update 21/2: The Herald picks up the Reuters story and expands it with a few (fairly old, I think) quotes from NIWA’s Jim Salinger. Interesting that the Herald predicts that we might be growing sauvignon blanc in Canterbury in 20 – 30 years. I wonder what that means for the 250,000 sav blanc vines already down the road from me….]

Being economical with the truth, or lying through her teeth?

homer.jpg Politicians are skilled at manipulating facts to convey any impression they desire. It’s called spin, and in its worst cases truthiness – nicely defined by the man who invented the term, Stephen Colbert of The Colbert Report: “We’re not talking about truth, we’re talking about something that seems like truth—the truth we want to exist.” Out in wingnut land, they want to believe that global warming is not real. So Muriel Newman at her NZ Centre for Political Research web site starts spinning the facts and, in the middle of a rambling attempt to justify a recent climate crank call for a joint Australia-NZ Royal Commission on climate change manages to come out with the following:

Anyone who claims that the science on global warming is settled is wrong. There is now growing evidence that that the earth is not warming but cooling: since the 1970s the glaciers of the Arctic, Greenland, and the Antarctic have been growing, and since 1998 average world temperatures have been falling with 2006 cooler than 2005 and 2007 cooler still.

This may be what Muriel fervently believes, but it is also completely untrue. So untrue, in fact, that saying it in an attempt to influence public policy amounts to lying. Sadly, in the echo chamber of truthiness around her web site, she gets taken at face value. Out in the wider world, it simply leaves her credibility in tatters.

Another Hot Topic, skiing’s future, batteries, kites, u.s.w.

There’s another Hot Topic on the bookshelves – not in NZ, but in the UK. Sir David King, the sometimes controversial scientific adviser to Tony Blair has (with Gabrielle Walker) penned The Hot Topic: How to Tackle Global Warming and Still Keep the Lights On. Reviews in The Times and The Guardian. It will no doubt make its way over here eventually.

Here come the warm jets

Hot Topic has devoted a lot of posts to events in the Arctic over the last northern hemisphere summer. The loss of sea ice was dramatic – there was 25% less ice in September than the previous record, set in 2005. The little graph to the left shows just far off the trend line last year’s September area really was. And as I posted yesterday, recent studies suggest that the Arctic is primed for more significant losses in the near future. If the reduction in summer sea ice continues, there are some pretty major implications for the climate of the northern hemisphere and for our modelling of the global climate, and it’s those things that I want to consider in this post. Please note: I am not a climate scientist, and there are a lot of ifs and handwaves in this argument, but bear with me…

A lie repeated is still a lie

It’s climate sceptic week at the Herald. On Monday they provided a platform for Bryan Leyland of the NZ C”S”C to repeat his tired old opposition to government energy strategy (nicely rebutted by I/S at No Right Turn), and this morning they give room to Garth George to offer his thoughts under the headline “Great global warming debate a bunch of hot air“. Garth’s views are not news – he’s been running this line for ages – but I am frankly astonished that the powers that be at the Herald allow him to repeat lies. Since fact-checking at the paper seems to have gone on holiday, it falls to me to provide the correction.
