Quote of the day, waste of money edition

It is important to recall that well over $1,700,000,000,000 ($1.7 trillion) has been spent on installing wind and solar devices in recent years with the sole objective of reducing global CO2 emissions. It transpires that since 1995 low carbon energy sources (nuclear, hydro and other renewables) share of global energy consumption has not changed at all.

New Zealand's temperature record

Richard Treadgold emails with details of an interesting new paper, with quite an eye-opening end to the abstract.

Yesterday a paper on the New Zealand temperature record (NZTR) was accepted by Environmental Modeling & Assessment. Submitted in 2013, we can only imagine the colossal peer-review hurdles that had to be overcome in gaining acceptance for a paper that refutes the national temperature record in a developed country. The mere fact of acceptance attests to a fundamental shift in scientific attitudes to climate change, but expect strident opposition to this paper.

McLean on clouds

John McLean, of James Cook University in Australia, emails with details of a paper he has just had published in Atmospheric and Climate Sciences about the warming of the planet at the end of the last century. He adds a useful layman's summary.

The paper ...

- indicates that the temperature pattern can be attributed to a sequence of events, namely a shift in the prevailing ENSO conditions, then a reduction in total cloud cover and then a shift on cloud (decrease in low level cloud that was largely offset by an increase in mid and upper level cloud)

- uses the Trenberth, Fasulo & Kiehl energy balance diagram to show that the loss in total cloud cover caused an increase in heat energy being absorbed at the Earth's surface that was greater than the increase that IPCC 5AR claims was due to greenhouse gases

Snail's pace - Josh 298

As Richard Betts notes here "I see the '2 degree limit' as rather like a speed limit on a road". And which is also quite an apt metaphor for the pause in global temperatures - slower than a not very extinct snail.

Richard B on the two-degree

A reader points me to this long tweet from Richard Betts, which I missed while I was away last week. It's certainly worth of reposting:

I see the '2 degree limit' as rather like a speed limit on a road - both are set by policymakers on the basis of a number of considerations.

On the roads, the main issues are safety, fuel economy and journey time. Regarding safety, driving at 5mph under the speed limit does not automatically make the journey 'safe', and exceeding the limit by 5mph does not automatically make it 'dangerous'. Clearly, all other rings being equal, the faster one travels the greater the danger from an accident - but you also want to go fast enough to get to your destination in a reasonable time. The level of danger at any particular speed depends on many factors, such as the nature of the particular road, the condition of the car and the skill of the driver. It would be too complicated and unworkable to set individual speed limits for individual circumstances taking into account all these factors, so clear and simple general speed limits are set using judgement and experience to try to get an overall balance between advantages and disadvantages of higher speeds for the community of road users as a whole. Basically, a simple limit is practical and workable.

Newsnight does Antarctic sea ice

I can barely keep up with all the climate and energy stuff on the airwaves in the last couple of days. Last night Matt Ridley and Tamsin Edwards were on Newsnight discussing the enigma of the increasing Antarctic sea ice. This was preceded by a review of recent theories about the science presented by Helen Czerski, which was pretty good really, and in particular touched on what I consider to be the key point: that if the models fail to predict changes in the ice then there is something missing in the models. This Eureka moment was then closely followed by Evan Davis noting that global warming is "all about the models".

Perhaps we are getting somewhere.

Maria McCaffrey on Radio 5

One more excerpt from yesterday's flurry of news pieces about renewables. This time it's Maria McCaffery of Renewable UK, who is someone whose public utterances generally have to be taken with a considerable pinch of salt.

It's no different this time.

Dieter Helm on energy policy

Dieter Helm's appearance before the House of Lords Science and Technology Committee today was pretty special, I gather. From his opening remarks - he said that it's a pretty amazing state of affairs that we are even discussing the possibility of power cuts and that we are failing on each of security, price and decarbonisation - that's certainly true. 

Video below or direct link here. Helm starts at 11:39.

Numbskull or nefarious?

Still on the subject of the National Grid report, Nicky Campbell on Radio Five Live interviewed Jeremy Nicholson of the Energy Intensive Users Group and Sally Uren, the CEO of Forum for the Future. This was a remarkable segment in more than one way.

The thing that has struck commenters here at BH was something Ms Uren said about the reliability of renewables. Accepting that the wind sometimes doesn't blow and the sun sometimes doesn't shine, she said:

...that's not a worry when we're thinking about security of supply from renewables because we have these things called "storage units" and so we have this grid that allows us to store energy and deal with peaks and troughs in demand and so this notion that when the sun stops shining and the wind stops blowing so does our energy, it's just not true.

Wheels coming off

As if we needed a reminder, it seems that National Grid have confirmed what we at BH have been saying for a while now, namely that the UK is facing an energy crisis this winter. As Emily Gosden reports in the Telegraph:

Britain's spare power capacity will fall this winter to a seven-year low, forcing emergency measures to prevent blackouts, a report on Tuesday is expected to say.

A series of power plant breakdowns and closures in recent months have eroded the safety buffer between maximum supply and peak demand, the report from National Grid is likely to show.

I gather that ministers have been grilled on the subject on the Today programme this morning and I'll try to post some audio when this becomes available.

Lew fan gong

Reality sometimes has the extraordinary ability to outdo even the most ludicrous works of fiction and the award of this year's Maddox Prize is certainly a case in point. The prize is awarded by Sense About Science for 'courage in promoting science and evidence on a matter of public interest' and this year the judges have picked an Oxford academic and Guardian columnist called David Grimes. Here is an example of his heroic work:

A series of investigations published last year by Prof Stephan Lewandowsky and his colleagues – including one with the fantastic title, Nasa Faked the Moon Landing – Therefore, (Climate) Science Is a Hoax: An Anatomy of the Motivated Rejection of Science – found that while subjects subscribing to conspiracist thought tended to reject all scientific propositions they encountered, those with strong traits of conservatism or pronounced free-market world views only tended to reject scientific findings with regulatory implications.

All the talents

Elizabeth Truss's performance on the Sunday Politics yesterday certainly caught the eye as an indication of the extraordinary levels of numptiness within the government, but it may be that another government minister has managed to go one better.

...Viscount Ridley, a Conservative peer and critic of government efforts to stop temperature rises, questioned [DECC minister Baroness Verma] on when warming would start again.

He told peers at question time in the House of Lords: 'The fifth assessment report of the Intergovernmental Panel On Climate Change has confirmed in the same words that there has been a hiatus in global warming for at least the last 15 years.'

Global swarming - Josh 297

Since the polar bear has been become something of a sceptic mascot, there's been a search for another cuddly animal to carry the Catastrophic Anthropogenic torch: cue the walrus. Sadly for alarmists it has not quite worked out.

A steady trickle

There is a steady trickle of articles coming through about the absurdity of energy and climate change policy in the UK. Take a look at this from the FT:

Although not a total consensus, the 2008 policy was grounded on the broad acceptance of four cornerstone propositions, which over time have turned to dust. These core beliefs were:

* fossil fuel prices would rise inexorably as global demand exceeded supply;

* Europe could gain a material competitive advantage by being the first major region in the world to develop a low-carbon economy based on renewables;

* a gradually rising carbon price would increase the cost of externalities including air pollution and climate change, until renewables became fully competitive;

* the negative effects of higher energy costs on competitiveness would be mitigated by a global deal with all the world’s major economies making progress towards the common goal of reducing emissions.

The inconvenient truth is that none of these beliefs have proved to be true.

Could it be that word is finally going to get round that all this greenery is a liability at the ballot box?
