Coal, There’s Just No Alternative

Tony Thomas mentions he has an opinion piece up on Quadrant about the reality of electricity and human wealth in all the ways not so obvious, but also right on the past cries of environmentalists deeming the undeveloped world must not get wealth.

Thomas discusses US author and energy specialist Robert Bryce

Bryce didn’t discuss the merits of the catastrophic human-caused global-warming hypothesis. He just delineated the irrationality of draconian global and national targets to cut CO2 emissions, given the developing world’s determination to use electricity to lift its people from poverty:

“I’m a resolute agnostic about the climate issue. Tell me CO2 is good, tell me it’s bad. I’m bored with the nastiness.

“The question that too few people are willing to ask is this one: where, how, will we find the energy equivalent of 27 Saudi Arabias and have it all be carbon-free?”

Oh yes, nastiness, a hallmark of forcing others to do your bidding…



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.


This article is cross posted from Tim’s blog as of interest to some Talkshop readers with a few extra sentences likely to raise discussion. 

August 2014 there was a meteorological gift of both exceptional conditions and good data. What can be learnt?

Three Met Office sites showed a signature of exponential cooling. This requires clear sky and a calm. Given somewhat limited parameter hourly data the following shows the commonality. The computed terminal conditions are shown later in this article.


Benson and Santon Downham data has been normalised to Katesbridge[3], which has the least noisy data or the three.

Achieving a close overlay requires taking earth rotation into account, dusk and dawn move relatively both by geographic location and the peculiar movement throughout the year as night length changes, these do not move together [1]. Fractional delay (less that the sample period) was used to equalize diurnal time. (see the two blog articles here)

Dusk appears to be the important factor, a surprising finding, I assume cooling is time from dusk, dawn terminates cooling.

General information, under essentially calm conditions wind drops for a period during the night then reappears just after dawn. (not shown here)

Temperature normalisation defined is for the cold period, not as accurate for Benson where the better site exposure (more open) led to more wind at times.

Modeling the Moon

A few months ago an analysis of the Moon’s equatorial temperature was posted here using two different types of engineering software. Tim Channon used SPICE circuit analysis software originally developed at Berkeley while I used Quickfield, a finite element analysis program developed by Tor Cooperative, a Russian firm, marketed outside Russia by Tera Analysis. In addition, several detailed comments were received from “br” who used LTSPICE from Linear Technology Inc.

Two very different methods. The results were identical.

Both Quickfield (in Student edition) and LTSPICE are freely available for download for those interested in replication or for further investigation.

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.’



On 5th August 2014 I archived the US Navy graphic of the track of hurricane Bertha into just a storm. Today is the 10th August 2014 where a storm is about to arrive in the UK with forecast fairly strong winds and rain. [update] Forget to mention, the timing is correct, dot over England was for 18hrs 10th.

This is a brief post pointing at my own low traffic blog where I am asking for assistance with finding a few Met Office sites. Not a pretty post, will bore ordinary readers but if you are tech, maybe.

On the other hand there is a huge list of Bing and Google links to aerial images. (150+)
Example, where is Sheffield CDL not a full site, temperature and humidity, that is the location given. :-)

Reblogged from Euan’s excellent site, Energy Matters.

“The Scottish Government’s targets are for renewable sources to generate the equivalent of 100 per cent of Scotland’s gross annual electricity consumption by 2020.” What will the consequences be for the Scottish People?

This post models Scottish electricity production and consumption in 2020 and compares this with 2012. It is assumed that Scotland’s two nuclear power stations remain operational in 2020. The reader is asked to always recall that the numbers are based on models and the conclusions therefore carry uncertainty. The consequences of this energy policy may be:

  • A large electricity surplus of about 15 TWh may be produced in 2020, worth about £2.5 billion at 17p / KWh.
  • There are currently many ideas but no certainty about where this surplus might go. It seems possible that a large part may simply be wasted.
  • Assuming that marine renewables remain negligible and hydro output remains unchanged in 2020 then the bulk of the expansion in renewables to meet the target will most likely be met by wind that will require a 5 fold increase relative to 2012.
  • In an independent Scotland the subsidy payments currently made to renewables companies by 63 million UK citizens would fall pro rata on the shoulders of 5.3 million Scottish citizens. This, combined with the 5 fold increase in wind capacity may mean a 25 fold increase in the level of renewable subsidy born by Scottish electricity consumers. Electricity bills may double.

In summary, the Scottish Government energy plan may result in a large electricity surplus that at present has nowhere to go, the number of wind turbines may increase 5 fold and electricity bills may double.


There has been some progress in the greenhouse. On the ‘toy planet’ thread, physicist Tim Folkerts now agrees with me that longwave infra-red radiated from the air towards the surface doesn’t directly heat the ocean but makes it harder for the ocean to cool. In my view this is due to IR radiation from the ocean making the air warm, reducing the temperature differential between ocean and air, slowing the rate of the Sun warmed ocean’s heat loss. Tim says:

LWIR is indeed incapable of “heating” the oceans in the strict sense of the word (net transfer of thermal energy). The best it can do is aid in making it “a far more difficult task escaping” for the energy.

But it’s hard for him to let go of ingrained notions, so his next comment is full of ambiguities, which I have tried to deal with in my followup comment:

Tim Folkerts: The DWIR DOES amount to ~ 330 W/m^2.

Fine, no problem.

This energy DOES get absorbed by the ocean.

In the top few microns, and is soon re-emitted along with an additional ~60W/m^2 IR, upwards.

The ocean IS warmer than it would be without this DWIR from the atmosphere.

But not because it is absorbed and re-emitted from the top few microns of ocean. The thermalisation of IR in the bulk air helps keep the air warm and that warm air slows the sun warmed ocean’s heat loss.

But the reason the air is warm is because the ocean warms it with the energy it emits into it which is absorbed and re-emitted, or conducted to the O2 and N2 in the air, by water vapour (from the ocean) and co2 (mostly from the ocean). Air has very little heat capacity of its own, and is nearly transparent to incoming solar short wave radiation. And this ocean warmed air is usually convecting upwards.


The Spectator has a good analysis on the BBC climate reporting bias debacle which coins a new phrase – ‘Climate Correctness’. A few excerpts:

gagging-ordersIt is only a matter of time before Nigel Lawson — if he is allowed on the BBC at all — has to have his words spoken by an actor in the manner of Gerry Adams at the height of the IRA’s bombing campaign during the 1980s. In the case of Mr Adams, whose voice was banned from the airwaves by the government, the BBC stood up for free speech. But it is quite a different story with Lord Lawson. The BBC has effectively banned the former chancellor (and former editor of this magazine) from appearing on its programmes to debate climate change, unless he is introduced with a statement discrediting his views.

When people try to close down debate rather than engage with it, there is a pretty clear conclusion to be drawn: they lack confidence in their own case. The suppression of debate was shown again this week when Vladimir Semonov, a climate scientist at the Geomar Institute in Kiel, Germany, revealed that a paper he wrote in 2009 questioning the accuracy of climate models used by the Intergovernmental Panel on Climate Change was effectively censored by the scientist to whom it was sent for review.


Greenhouse effectsFollowing on from our recent debate on the likely extent of the greenhouse effect on Earth, this post will broaden the scope of discussion by allowing consideration of planetary surface temperatures on imaginary worlds. Tim Folkerts proposes a world at the distance from the Sun of our moon (i.e. the same average distance as Earth), with a twist on surface composition:


Just out of curiosity, if I put a ball of water — say a few km in diameter — in some sort of clear plastic baggie to keep it together and prevent evaporation in orbit around the sun @ 1 AU, are you claiming the water inside the baggie will be at least 80 C everywhere?

Or if I put a series of such plastic baggies on the moon to cover the entire surface with water 1 km deep that cannot evaporate, that the surface of the moon would be at or above 80 C everywhere (lets even limit the question to the “tropics” out to ~ 30 degrees N & S to avoid question about what happens at the poles)?

(We could even make the baggie slightly elastic to apply 1 Atm of pressure inward on the ball of water).


Tim appears to have misunderstood what Konrad and I are telling him about the atmosphere being a cooling agent rather than a warming agent, and how pressure acts to slow the loss of energy from the oceans via the atmospheric suppression of evaporation and the increased density of a near surface atmosphere, which is not present on his toy planet.

The record of recent Man-made CO2 emissions:  1965 -2013

The following calculations and graphics are based on information on national CO2 emission levels worldwide published by BP[1]in June 2014 for the period from 1965 up until 2013.  The data is well corroborated by previous similar datasets published by the CDIAC, Guardian [2] and Google up until 2009 [3].  These notes and figures provide a short commentary on that CO2 emissions history.
The contrast between the developed and developing worlds is stark in terms of their history of CO2 emissions and the likely prognosis for their future CO2 output.


Figure 1

Since 1980 CO2 emissions from the developed world have shown virtually no increase, whereas the developing world has had a fourfold increase since 1980:  that increase is accelerating.

Brandon’s take on the temperature record debacle

Originally posted on Izuru:

There has been a lot of hoopla about supposed problems in the surface temperature record recently. Unfortunately, a lot of people don’t seem to understand what the hoopla is actually about. I think the problem is people have focused too much on rhetoric and too little on actual information. I’d like to try to reverse that.

David Archibald’s prediction for global average temperature 2014-2025

David Archibald’s post at has stirred some interesting debate here at the talkshop. David predicts an imminent and steep drop in regional temperatures as a result of the slowdown in solar activity seen since the descent of solar cycle 23 in 2003. It’s not the first time he has made such predictions. As Nick Stokes pointed out in discussion, Archibald told the Australian senate committee in 2009 that temperature was about to go down at a scary 0.2C per annum. It didn’t happen. But David says it’s different this time, because a decade has passed since solar cycle 23 dropped towards a long minimum, followed by the weak cycle 24 we are currently in. The decadal lag is implied by David Evan’s new hypothesis which identifies a ‘notch filter’ which points to a cycle-long lag between changes in solar activity and the effect becoming visible in the terrestrial response. David goes on to predict that due to Penn and Livingstone’s prediction of a very low sunspot number in cycle 25, we are headed for drastic cooling.

There are several points on which I disagree with David’s analysis, and I’ll cover them below the break.


Thanks to commenter ‘psc3113′ for finding the concluding part of HC Russells’ paper on a lunar 19 year cycle in drought records, taken from The Queenslander (Brisbane, Qld. : 1866 – 1939)  Saturday 4 July 1896. At the conclusion of the article, the probably cause of the 19 year cycle identified is elucidated.

Periodicity of Good and Bad Seasons
(Continued from last Week.)

Hurricanes Come in Droughts.
I should like it to be clearly understood that I do not mean ordinary hurricanes, which are as much parts of ordinary weather conditions in some parts of the world as our southerly winds are here. What I mean are extraordinary hurricanes, those that come at long intervals to terrify mankind by their power for destruction. These are connected with droughts, and, therefore should be discussed here. I had long since observed that the connection between the two was obvious enough sometimes, and during the past year I was reminded of it very often by the frequent reports of heavy gales met with by ships coming to this port, indicating great atmospheric energy. Then on the 3rd January, 1803, came the hurricane over the Tongan group of islands, and not one of the vessels in the harbour rode out the storm; every one of them was wrecked in the harbour before morning, and the wind was of such exceptional violence that after it was over the islands looked as if they had been bombarded.

Then I turned to storms on this coast, some of which were of terrible violence. And as I write, the 28th ‘May, we have the report of a terrible cyclone in America, by which three of the States, Missouri, Illinois, and Indiana were damaged and the city of St. Louis wrecked. and 1300 people killed by falling buildings, and damage to property caused to the extent, estimated, of twenty million dollars; another fragment of the present D drought.


Since I posted on the crash, an update when the primary crash report is published is reasonable even though this is off the blog normal fare. Engineering types tend to have wide interests

Reuters report

U.S. investigators propose review of flight controls after Asiana crash

By Alwyn Scott and Annika McGinnis

WASHINGTON Tue Jun 24, 2014 10:14pm BST

(Reuters) – U.S. investigators on Tuesday said Boeing Co should consider modifying flight controls on the 777 jetliner in response to an Asiana Airlines crash in San Francisco last July that killed three people and injured more than 180.

The National Transportation Safety Board accepted 30 findings following an 11-month investigation into the July 6, 2013 crash, and made more than two dozen recommendations to the Federal Aviation Administration, the Seoul-based airline, Boeing, firefighters and San Francisco city and county.


While browsing Ian Wilson’s excellent Astro-Climate Connection blog, I found a graphic showing the coincidence of El Nino with the alignment of the Lunar line of nodes (declination cycle) and line of apse (orbital precession), with the Sun. I’ve taken the liberty of adding my Solar – El Nino hypothesis to it: the proposal is that El Nino tends to be initiated as the cycle starts to decline steeply and initiated again at solar minimum as it ‘bottom’s out’. I’ll reproduce Ian’s accompanying text below the break but to get to the point, here’s  the result:



From Ian Wilson’s Astro-Climate Connection blog:


The Moon’s orbit is tilted by approximately five degrees compared to the Earth-Sun plane. The net affect of this is that the strength of Lunar-tides at a given latitude on the Earth’s surface vary in strength over a cycle of 18.6 years. This 18.6 year Draconic cycle is also clearly evident in the small changes that take place in the rate of rotation of the Earth.


An interesting series of posts has appeared at Jo Nova’s site. Jo’s husband, David Evans has done some competent analysis work to unravel the observed ~11 yr ‘delay’ in terrestrial climatic response to solar input. Of interest is the obervation that the solar polar magnetic fields are in the process of weakeneing and changing sign near solar maximum. It is suspected that this is connected with the delay. Head on over to read the posts and comment there as well as here.
