Ex-Environment minister Owen Paterson is tonight delivering the annual GWPF lecture. In it he will say the climate change act should be scrapped. UKIP has been saying this for years and has had a detailed energy policy document out for years detailing better alternatives for a viable mixed energy policy. The full text of his speech has been published at the Spectator. Here’s an except:

The vital importance of affordable energy

owen-patersonBut first, let us consider what is at stake. We now live in an almost totally computer-dependent world. Without secure power the whole of our modern civilisation collapses: banking, air traffic control, smart phones, refrigerated food, life-saving surgery, entertainment, education, industry and transport.

We are lucky to live in a country where energy has been affordable and reliable.

Yet we cannot take this for granted.

While most public discussion is driven by the immediacy of the looming 2020 EU renewables target; policy is actually dominated by the EU’s long-term 2050 target.

The 2050 target is for a reduction in greenhouse gas emissions by 80 percent relative to 1990 levels. The target has been outlined by the European Commission. But it is only the UK that has made it legally binding through the Climate Change Act – a piece of legislation that I and virtually every other MP voted for.

The 2050 target of cutting emissions by 80 percent, requires the almost complete decarbonisation of the electricity supply in 36 years.

In the short and medium term, costs to consumers will rise dramatically, and the lights would eventually go out. Not because of a temporary shortfall, but because of structural failures, from which we will find it extremely difficult and expensive to recover.

We must act now.

Geothermal flux and the deep oceans.

To appreciate how the small geothermal flux of ~100 mW/m2 can play a significant role in our climate we’ll take a look at a cross-section of the Pacific in Fig 1.


Fig 1

A typical temperature profile is given in Fig 2 below

Fig 2

Fig 2

First the profile below ~1000 m. Slowly decreasing temperature with depth, more or less the same for all latitudes. The dark blue layer (~30 C) can be regarded as the top of the cold deep oceans. From 1000 m. upward the temperature increases rapidly, warmest water at the surface in the (sub) tropics. The dark blue layer only reaches the surface at high latitudes (red arrows). All water above this dark blue layer is warmed from above by the sun, either directly or indirectly. This layer also loses its energy again at the surface to the atmosphere, and eventually to space. Solar energy only warms the upper ~1000 m. between ~50N and 55S. How high the surface temperatures will be, depends on the temperature of the deep oceans and how much the sun can warm the upper layer above the deep ocean temperature.

We’ll highlight some points from the official reaction later but first the opening details from a press report. Note the eagerness to talk down the relevance of Antarctic sea ice.

‘Sea ice surrounding Antarctica reached a new record high extent this year, covering more of the southern oceans than it has since scientists began a long-term satellite record to map sea ice extent in the late 1970s. The upward trend in the Antarctic, however, is only about a third of the magnitude of the rapid loss of sea ice in the Arctic Ocean.’

‘The new Antarctic sea ice record reflects the diversity and complexity of Earth’s environments, said NASA researchers. Claire Parkinson, a senior scientist at NASA’s Goddard Space Flight Center, has referred to changes in sea ice coverage as a microcosm of global climate change.’


Hot off the press release press, NASA tells us what I’ve been telling everyone who will listen for the last four years – large amounts of heat cannot magically descend through a marginally warming (or cooling) upper ocean to lurk in the abyss… The second law of thermodynamics doesn’t like that sort of thing.

While the upper part of the world’s oceans continue to absorb heat from global warming, ocean depths have not warmed measurably in the last decade.

The cold waters of Earth’s deep ocean have not warmed measurably since 2005, according to a new NASA study, leaving unsolved the mystery of why global warming appears to have slowed in recent years.

Scientists at NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California, analyzed satellite and direct ocean temperature data from 2005 to 2013 and found the ocean abyss below 1.24 miles (1,995 meters) has not warmed measurably. Study coauthor Josh Willis of JPL said these findings do not throw suspicion on climate change itself.

“The sea level is still rising,” Willis noted. “We’re just trying to understand the nitty-gritty details.”

In the 21st century, greenhouse gases have continued to accumulate in the atmosphere, just as they did in the 20th century, but global average surface air temperatures have stopped rising in tandem with the gases. The temperature of the top half of the world’s oceans — above the 1.24-mile mark — is still climbing, but not fast enough to account for the stalled air temperatures.


The plot below needs little explanation. The globally average surface temperature hasn’t warmed in over 18 years according to the RSS satellite dataset.



Now, Some say the surface hasn’t warmed because the ‘missing heat’ has gone into the oceans instead of warming the surface.However, if we look at ARGO; the best data we have for ocean heat content (OHC) (before it got reworked in 2010 by dropping buoys showing cooling from the dataset) – we see that Ocean Heat Content actually fell from 2003 to 2008:


Where else could the heat have ‘hidden’? Well, the warmists claim it went deeper than the bulk of the ARGO system measures – below 700m, where uncertainty rises dramatically. However, they offer no plausible explanation of how energy is transferred through a 700m deep COOLING layer, in defiance of the second law of thermodynamics.


bare-arsed2No reply from the eminent atmospheric physics professor… any takers?

Dear Professor xxxxxxx,

I am trying to better understand the physics underlying atmospheric science and wondered if you could answer a question for me.

The Modtran model successfully predicts the local temperature throughout the troposphere, but how do we determine the extent to which the level of radiative activity at a particular altitude is the effect of the local temperature at that altitude rather than the cause of it?

I ask because it appears from my limited reading and understanding that the theoretical underpinning of radiative-convective models neglects the effect of sea level pressure on the rate of evaporation, which must surely have a significant effect on the rate at which the ocean is able to shed the energy input to it by solar radiation.

Someone the current US President might do well to listen to before voicing opinions on climate matters is profiled here.

E & E News reports: Judith Curry thinks climate scientists view her as their “biggest threat.”

“I do not pay obeisance to the consensus and I think for myself, and they don’t like that,” said Curry, a professor at the School of Earth and Atmospheric Sciences at the Georgia Institute of Technology.

This is a follow-on from another recent Talkshop post:

The principal cause of bi-decadal climatic variation – The Hale cycle, or something else?

The subject is a paper that appeared in 2009 which relates to the discussion.
Hopefully the following abstract of it speaks for itself.


Paul Vaughan has suggested we hold a discussion on bi-decadal climatic variation, which exhibits quasi-cyclic patterns in various datasets. To get the ball rolling, Paul has kindly given some time to producing some very interesting plots which he has introduced across a few recent threads. This posts puts these in one place and acts as an invitation to those interested in a focussed discussion on the topic.

The Bidecadal Oscillation

Is it caused by the solar Hale Cycle as suggested by Tim Channon or is it caused by the velocity of the sun with respect to the solar system barycenter as suggested by Nicola Scafetta?


It’s 10 years since the death of John Daly, but we forgot to mark this decadal anniversary back at the end of January. Here is the article by John Izzard originally published at in 2009, which looks back at his life and work. If anyone has a copy of his book “The Greenhouse Trap” please let me know. Google and Amazon aren’t interested (and probably think n0-one else should be either).

John L. Daly (31 March 1943 – 29 January 2004)

Daly-picYesterday I visited John L. Daly’s tiny office where he lived on the outskirts of Launceston. It is about the size of two telephone boxes. His wife, Amy, has kept is just as it was when John died in 2004. His computer, his files, the maps on the wall — his notes, letters, photographs and dairies. She has also kept alive his web-site which he was still updating at the time of his death.

Looking at his scientific work today gives an insight into why the people at the IPCC (Intergovernmental Panel on Climate Change) and the University of East Anglia’s Climatic Research Unit were so annoyed with Daly’s work and why he was such a thorn in the side of their climate theories and research.



Matt Ridley: Whatever Happened To Global Warming?
Date: 05/09/14 Matt Ridley, The Wall Street Journal

whateverGWOn Sept. 23 the United Nations will host a party for world leaders in New York to pledge urgent action against climate change. Yet leaders from China, India and Germany have already announced that they won’t attend the summit and others are likely to follow, leaving President Obama looking a bit lonely. Could it be that they no longer regard it as an urgent threat that some time later in this century the air may get a bit warmer?

In effect, this is all that’s left of the global-warming emergency the U.N. declared in its first report on the subject in 1990. The U.N. no longer claims that there will be dangerous or rapid climate change in the next two decades. Last September, between the second and final draft of its fifth assessment report, the U.N.’s Intergovernmental Panel on Climate Change quietly downgraded the warming it expected in the 30 years following 1995, to about 0.5 degrees Celsius from 0.7 (or, in Fahrenheit, to about 0.9 degrees, from 1.3).

Even that is likely to be too high. The climate-research establishment has finally admitted openly what skeptic scientists have been saying for nearly a decade: Global warming has stopped since shortly before this century began.


Has Joe done what Uncle Sam couldn’t?

Some say money can buy brains, brains are cheap. Duffers think that, make the mistake of confusing rote with The Spark. As a wit said ‘the most intelligent person in the room is the room’… to which I add, buying others to inside still leaves the room. Self selection is recursive.

There again for here, an oscillation does not explain itself. Small step first.

Joe Bastardi is writing sense, Gosselin runs with it.

Large scale oceanic oscillations responsible for most of the post 1980 “warming”

By Joe Bastardi

I think global warming is a misnomer.

There is a distortion of the temperature pattern on the globe, brought about by the natural cyclical warming events of the warm PDO and warm AMO together. I spoke about this at Heartland a couple of years ago – how the sea ice increase in the south and the decrease in the north were the hidden message that here is no “warming” just a distortion.

Bad news for fans of global warming theory dreaming of ‘strong’ El Ninos or indeed anything that might point global temperature stats in an upward direction.

Even the BBC is having to come to terms with climate reality, to some limited extent at least.

This is worth a look just for the last paragraph, which undermines most of the rest of it. Under the optimistic sub-heading ‘Warming to recommence’ we find:

‘Despite the warming hiatus, Knutti is convinced there is no reason to doubt either the existing calculations for the climate activity of greenhouse gases or the latest climate models.’

“Short-term climate fluctuations can easily be explained. They do not alter the fact that the climate will become considerably warmer in the long term as a result of greenhouse gas emissions,” says Knutti.

‘He believes that global warming will recommence as soon as solar activity, aerosol concentrations in the atmosphere and weather phenomena such as El Niño naturally start returning to the values of previous decades.’ [bold added]

Translation: as soon as the sun, the weather and volcanoes – all natural factors – allow, the world will start warming again. Who knew?

Good to hear a warmist trashing his own theory in order to explain the lack of temperature rise this century – without realising it.

“The fundamental laws of physics say that as the temperature goes up, it has to get warmer,” Liu says.

Nice work Professor. Homer Simpson couldn’t have put it better.

So you still take "climate scientists" seriously?

El Niño and its twin La Niña are under the spotlight this year as climate-watchers hunt for signs of expected activity that seems to have gone largely missing in recent years if compared to, say, the 1990s.

Has the strength of these phenomena changed in modern times? Apparently not.

‘The charts created by the research team suggest that the ENSO cycle does not have a predictable cycle and also that it has not been increasing in strength over the course of the Holocene as others have suggested.’

Fishy business – James Delingpole takes aim at the Telegraph’s leading ‘green’ reporter. Hard to miss really.

Dellers: ‘The Telegraph’s resident enviro loon Geoffrey Lean has come up with some new terrifying evidence for the existence of “global warming.” ‘

‘So what, er, is the new most important metric for global temperature rises, now that it’s not measured global temperature rises, our Geoff?
Well, apparently, it’s…’

As The Hockeyshtick reports:

‘A paper published today in the Journal of Geophysical Research Space Physics finds that recent low solar activity “mirrors” extended solar minimums in the 19th and early 20th centuries, as well as other periods over the past 1000 years consistent with the Centennial Gleissberg Cycle of solar activity. Such periods have also been associated with global cooling.’

The co-authors of the paper are (quoting The Hockeyshtick):

Piers Corbyn has made a weather forecast. Nothing new there, that’s his line of work. But this one has caught the attention of at least one organ of the UK national press [warning: loud headline ahead]…
Daily Express report

Reading the forecast, it clearly states the behaviour of the jet stream is the key factor. So what are the chances of showing any significant link between the behaviour of jet streams and small variations in atmospheric trace gases? They appear to be remote at present.
