Missing the point by miles

I have been steering clear of Wishart-related material for the last week or two (on the “wrestling with pigs” principle), but I can’t let this post at his blog pass without comment. It begins:

In the climate debate, we can choose to listen to truffle fanciers like Gareth at Hot Topic, journalists like myself or politicians like Al Gore, or one of the leading scientists in the climate field, like Roy Spencer from University of Alabama-Huntsville. The following is a fascinating essay from his blogsite, which backs up the central thesis in Air Con – most of the CO2 increase is natural, not man-made:

He then reposts Spencer’s blog item in full, adding in the comments:

Spencer’s study suggests strong evidence that oceanic CO2 is the primary driver of increased CO2 levels in the atmosphere. (Looking at the graphs, very strong evidence).

Not a squeak out of Hot Topic and no one posting here challenges it.

Notice how a blog post became a “study”? Ah well, here’s a squeak…

Blackleg miner

NZcoal.jpgSolid Energy, NZ’s state-owned coal mining company, is promoting an alternative to an economy wide emissions trading scheme. According to Carbon News, the approach is being “heavily peddled to policy makers and others in Wellington”, and it is seen to have “great simplistic appeal”. Carbon News has made the document, A Durable Climate Change Strategy for New Zealand, available here.

The essence of the scheme, once you plough through Solid Energy’s reasons for disliking the ETS as currently proposed, is that the government should plant lots of trees, funded by a $1/tonne carbon levy applied across the economy. Lots and lots of trees — a million hectares of new exotic and native forest planted over the next 20-30 years. Solid Energy claims that “Kiwiforest” would provide enough cheap carbon sequestration to allow the economy to grow without the need to impose steep carbon prices. An ETS would only be introduced when there was a truly global interlinked network of carbon markets.

Sounds attractive, on the face of it. Who could object to planting lots of trees? Certainly not me. Unfortunately, as a national emissions strategy it looks too simplistic to be realistic, and on Solid Energy’s numbers delivers emissions reductions that aren’t credible.

The inner mounting flame

Burningice.jpg

The rapid climate change underway in the Arctic has the potential to disrupt weather patterns around the planet, and brings with it the risk that methane bubbling out of the permafrost that rings the Arctic Ocean and from gas hydrates under the sea floor could make our attempts to restrain emissions and stabilise atmospheric greenhouse gases completely irrelevant. These concerns will not be news to Hot Topic regulars (try the methane and Arctic tags for earlier posts and background), but a thorough overview by Fred Pearce in last week’s New Scientist (Arctic meltdown is a threat to all humanity) pulls all the threads together and presents them in a compelling fashion. Pearce begins by looking at the experiences of Katey Walter:

“I am shocked, truly shocked,” says Katey Walter, an ecologist at the University of Alaska in Fairbanks. “I was in Siberia a few weeks ago, and I am now just back in from the field in Alaska. The permafrost is melting fast all over the Arctic, lakes are forming everywhere and methane is bubbling up out of them.”

Back in 2006, in a paper in Nature, Walter warned that as the permafrost in Siberia melted, growing methane emissions could accelerate climate change. But even she was not expecting such a rapid change. “Lakes in Siberia are five times bigger than when I measured them in 2006. It’s unprecedented. This is a global event now, and the inertia for more permafrost melt is increasing.”

Not good news.

Stern talking (but not Nick)

At the UNFCCC Climate Change talks currently under way in Bonn the US Envoy Todd Stern has unequivocally announced the role the US will be playing in the time ahead.  It is an extraordinary transformation. The hopes raised by Obama still look strong.

Some extracts follow. First, the opening remarks:

Telling porkies to Parliament

NZETS.jpgThe Emissions Trading Scheme Review committee has released the first batch of submissions it has received — those made by organisations and individuals who have already made their presentations to the committee. There are some heavy hitters in there: from New Zealand’s science and policy community there’s the Climate Change Centre (a joint venture between the University of Canterbury and Victoria University of Wellington, plus all the Crown Research Institutes – from NIWA to AgResearch), VUW’s Climate Change Research Institute, and GNS Science, and from the world of commerce, we have the Business Roundtable‘s “evidence”. Why the quote marks? Because the Roundtable’s submission is a fact-free farrago of nonsense.
