Five climate futures

As I see it, there are five possible global climate temperature scenarios for the next five years. Apart from the unexpected that is! 

1. Unambiguous warming.
2. Ambiguous warming.
3. No change.
4. Ambiguous cooling.
5. Unambiguous cooling.

Scenarios 2, 3 and 4 are where various misguided enthusiasts claim we are at the moment. Climate science is too inexact in its definitions and too saturated with political exigencies for a neutral observer to distinguish between them. Not that there are any neutral observers in this debate.

Even so, what may we say about the coming five years with some degree of confidence? Obviously we have to guess, but if we are able to get over the idea that this has much to do with science, then we may get somewhere.

Commonly observed traits of human behaviour are what guide us through the climate debate which in my view is mostly driven by global political ambitions, middle class anxieties and an undue respect for authority. Even so, it is surely possible to get away from the failures of climate science and take a look at human nature.

Scenarios 1 and 2 should ensure the political and intellectual survival of mainstream pro-AGW climate narratives. The other three, namely 3, 4 and 5 will obviously cause increasingly severe problems for the mainstream narrative.

If we assume that all five narratives are equally probable, and we have no science to tell us otherwise, then there is a 60% chance that the mainstream pro-AGW narrative may fail very badly indeed. It depends of the resilience of the narrative which is undoubtedly powerful for both political and emotional reasons.

On the other hand, there is a 40% chance that it will succeed politically and intellectually, at least for that five year period.

Not that these percentages should be taken too seriously, but we have to make sense of climate change somehow and the mainstream science isn’t getting us anywhere. Most of it is far too speculative as a basis for energy policies which one way or another will end up being driven by the real world.

John Cook's Climate Change Mythbusters 20

This is part of a series reposting material from John Cook's Skeptical Science website. Although he is a physicist rather than a specialist in climate science, he is a convinced "global warmist" and tries to rebut frequently-raised objections to the theory. However, it is always possible to question the data (e.g. this valuable note about measuring temperature) and the line of argument. Please help advance the debate - with facts and logic.

Are glaciers growing or retreating?

What The Science Says:
Most glaciers are retreating, posing a serious problem for millions who rely on glaciers for water.

Climate Myth: Glaciers are growing
“[R]eports are coming in from all over the world: for the first time in over 250 years, glaciers in Alaska, Canada, New Zealand, Greenland, and now Norway are growing.”(JamulBlog)

Although Glaciologists measure year-to-year changes in glacier activity, it is the long term changes which provide the basis for statements such as "Global Glacier Recession Continues". Some Skeptics confuse these issues by cherry picking individual glaciers or by ignoring long term trends. Diversions such as these do not address the most important question of what is the real state of glaciers globally?

The answer is not only clear but it is definitive and based on the scientific literature. Globally glaciers are losing ice at an extensive rate (Figure 1). There are still situations in which glaciers gain or lose ice more than typical for one region or another but the long term trends are all the same, and about 90% of glaciers are shrinking worldwide (Figure 2).


Figure 1: Long-term changes in glacier volume adapted from Cogley 2009.
 

Figure 2: Percentage of shrinking and growing glaciers in 2008–2009, from the 2011 WGMS report

It is also very important to understand that glacier changes are not only dictated by air temperature changes but also by precipitation. Therefore, there are scenarios in which warming can lead to increases in precipitation (and thus glacier ice accumulation) such as displayed in part of southwestern Norway during the 1990s (Nesje et al 2008).

The bottom line is that glacier variations can be dependent on localized conditions but that these variations are superimposed on a clear and evident long term global reduction in glacier volume which has accelerated rapidly since the 1970s.

Is Al Gore's An Inconvenient Truth accurate?

What The Science Says:
Al Gore's film was "broadly accurate" according to an expert witness called when an attempt was made through the courts to prevent the film being shown in schools.

Climate Myth: Al Gore got it wrong
“Al Gore's Oscar-winning documentary on global warming, An Inconvenient Truth, was […] criticised by a high court judge who highlighted what he said were "nine scientific errors" in the film.

Mr Justice Barton yesterday said that while the film was "broadly accurate" in its presentation of climate change, he identified nine significant errors in the film, some of which, he said, had arisen in "the context of alarmism and exaggeration" to support the former US vice-president's views on climate change.” (The Guardian)

Al Gore, certainly the most vilified proponent of climate change anywhere in the world, earned most of this enmity through the success of a film he presented called An Inconvenient Truth (AIT). The film was a staid presentation of climate science to date, a round-up of research, science and projections, with many cinematic sequences employed to harness the power of the medium.

The majority of the film, covering issues like Himalayan Glaciers, Greenland and Antarctica losing ice, the severity of hurricanes and other weather phenomena, was accurate and represented the science as it stood. Since the release of the film, considerably more evidence has been found in support of the science and projections in the film.

One claim was in error, as was one attribution of a graph. The error was in the claim that climate change had caused the shrinking of Mount Kilimanjaro, although the evidence that the shrinkage was most likely caused by deforestation did not appear until after the film was made. The error of attribution was in reference to a graph of temperature and attributes it mistakenly to a Dr. Thompson, when it was actually a combination of Mann’s hockey stick and CRU surface temperature data.

The Legal Case

The film is also subject to attack on the grounds that Al Gore was prosecuted in the UK and a judge found many errors in the film. This is untrue.

The case, heard in the civil court, was brought by a school governor against the Secretary of State for Education, in an attempt to prevent the film being distributed to schools. Mr. Justice Burton, in his judgement, ordered that teaching notes accompanying the film should be modified to clarify the speculative (and occasionally hyperbolic) presentation of some issues.

Mr. Justice Burton found no errors at all in the science. In his written judgement, the word error appears in quotes each time it is used – nine points formed the entirety of his judgement - indicating that he did not support the assertion the points were erroneous. About the film in general, he said this:

17. I turn to AIT, the film. The following is clear:

i) It is substantially founded upon scientific research and fact, albeit that the science is used, in the hands of a talented politician and communicator, to make a political statement and to support a political programme.

22. I have no doubt that Dr Stott, the Defendant's expert, is right when he says that:

"Al Gore's presentation of the causes and likely effects of climate change in the film was broadly accurate."

The judge did identify statements that had political implications he felt needed qualification in the guidance notes for teachers, and ordered that both qualifications on the science and the political implications should be included in the notes. Al Gore was not involved in the case, was not prosecuted, and because the trial was not a criminal case, there was no jury, and no guilty verdict was handed down.

Note: the vilification of Al Gore is best understood in the context of personalisation. When opponents attack something abstract - like science - the public may not associate with the argument. By giving a name and a face and a set of behavioural characteristics - being a rich politician, for example - it is easy to create a fictional enemy through inference and association. Al Gore is a successful politician who presented a film, his training and experience suitable to the task. To invoke Gore is a way to obfuscate about climate science, for which Gore has neither responsibility, claim nor blame.

Fukushima radiation: should we worry?

First, the scare. Michael Snyder gives a raft of facts to show that post-Fukushima, radiation levels have increased around the west coast of America. Professor Michel Chossudovsky discusses the spread of radiactive fallout from Japan under the shock title "... A Nuclear War Without A War..." - somwhat insensitively bearing in mind that Japan is the only country to have been atom-bombed. The Liberty Beacon relays official US information on the plume of water-borne radioactivity.

Then, some critical comment and reassurance. American Live Wire shows that a dramatic graphic purporting to show the spread of radiation across the Pacific is actually a map of increased wave height from the tsunami. And the ever-informative xkcd freely offers the following infographic on normal and acceptable radiation dosage (click on caption for full size picture):

http://xkcd.com/radiation/

Finally, the rational concern: as with the now-banned pesticide DDT, the most significant potential damage could be concentration of the toxic substances as they rise through the food chain. Now, shoppers in Korea are using Geiger counters to check imports of "eastern sea" fish, and as early as January 2012 the readings from seaweed were 3 times higher than background:



Fish (like tuna) that eat other fish; scavengers like crab and lobster; plankton and krill (and the whales that eat them), squid... we may be advised not to eat Pacific seafood. Already Seoul has banned imports from the Fukushima region. And it's possible that wildlife is suffering from the disaster.

What if there was a bigger disaster? There's been much excited speculation about the consequences of a potential collapse of the spent fuel storage that could result in fire and evacuation. Paul Blustein at Slate.com discusses this coolly and concludes that it could be very bad, though not apocalyptic.

Enter The Chinese Dragon - and the start of bonded servitude

Under foreign flags

Readers may be aware that I am generally untroubled by inward investment and foreign ownership of UK assets, though this is clearly not a view shared by all who visit these pages.

The Chinese aspect in this week's jaw-dropping (if highly trailed) nuclear announcement is a bit different, though.  There is the national security angle, of course, and many will be most agitated by that.  I don't dismiss it, but it's not what strikes me the hardest.  Security of supply is a non-issue: the Americans tried to pin that on Russia as a gas supplier during the Cold War and it never stuck.  Safety ?  Technology ?  All issues that can be resolved - if you count buying the ridiculous EDF / Areva EPR technology as a good idea in the first place.

More foreign flags

I am more concerned about what it signals, or rather confirms, about what I have long felt to be the probable strategic response of European governments to our parlous financial position.  A couple of years ago I wrote that when we are really up a gum tree the Chinese will have a deal for us, and we will meekly sell the farm.

This is a particularly acute risk for the UK, in my assessment.  In our semi-detatched euro-positioning, our vulnerability to having the City isolated by jealous continental and American financial authorities, and our commendable centuries-old willingness to roam the high seas, we will always be inclined to 'trade our way out of trouble'.  

Now true commercial trade is a great thing and would indeed be the ideal way forward.  But increasingly what we see is a baser trade: the prostituting of our institutions to the whim of Russian and Chinese wealth.  If they want to lavish their money on our libel courts or Mayfair shops, that's one thing.  But it won't be ending there.

Today we see the first of the mega-bargains our desperate UK politicians will enter in order to engineer short- and medium-term relief from our woes.  Faustian is just one way to describe it.  Another would be the PFI-ing of the UK economy to China.  Future generations will curse Camerosborne roundly, as they pay grotesque prices for electricity and probably a great deal more.

And the prices may not only be measured in currency.  Bonded servitude may be the term we are looking for.

Teaching our children to be fat diabetics?

Market Ticker commentator Karl Denninger is a convert to low-carbohydrate diets, having lost 60 pounds. He says - and I've seen this allegation elesewhere - that dietary advice in favour of starch suits commercial interests while bloating and killing the populace.

Meanwhile, around the UK, a standard part of the primary curriculum continues to promote carbs as the foundation of healthy eating, as witness this graphic from a local school:

Do we teachers know anything at all?
