India and China have already won and the Paris climate conference has become irrelevant

Paris conference

Paris conference

India and China have successfully managed to get the UN to focus on the intensity of emissions per unit of GDP and thus can make promises (not legally binding) about future emissions tied to GDP such that they will not be limited in their use of coal in any significant way.

The hype about the UN’s December climate meeting in Paris is gradually growing. Media, politically correct politicians and the global warming religion’s orthodoxy are winding up their rhetoric. Ostensibly the goal is to demonise carbon and to get nations to commit to reducing fossil fuel use such that the global temperature rise “will not exceed 2ºC”. This target of “allowable” temperature rise is not “2ºC caused by man” but just “2ºC”. Nobody actually knows what the rise by “natural causes” might be and what is caused by man. “Global temperature” itself is an artefact, a calculated quantity and calculated by those with a vested interest in showing that it is increasing. It seems that the calculation method is conveniently variable and is adjusted every year to show that the current year has demonstrated the highest ever temperature. Nevertheless the 5,000 participants and 190+ countries have effectively set themselves up to discuss commitments to stop climate change itself. The arrogance is astounding and worthy of King Cnut.

What effect man has actually had on climate is unknown. For almost 20 years now, man-made carbon dioxide emissions have been growing explosively but “global temperature” has paused. Those countries which have increased their own costs of electricity by reducing fossil fuel use (mainly in Europe) have effectively done it all quite uselessly and unnecessarily. Other countries (China and India in the main) have increased their use of fossil fuels such that global emissions of carbon dioxide have continued to grow. And yet there has been no change in “global temperature” except by arithmetical tricks. The last 3 decades of reducing fossil fuel use in Europe have been unnecessary. Three decades of subsidising renewable energy have still not made them commercial in their own right.

Climate policies are all policies where the objectives are not measurable. Policies are being proposed where the effect of the policies on climate itself cannot be measured. All that can be measured are the actions themselves which is both trivial and meaningless. For example countries can measure amounts of money spent but have no clue as to what the resultant effect on climate may be. Emissions reductions can be measured, but not the actual climate effects such reductions may have caused or not caused. For many delegates the purpose is not climate but the redistribution of wealth among nations where climate policy is the vehicle.

Ask a politician what his countries climate policies will achieve and the answer is that it will “contribute to the world’s efforts to stop climate change”. But by how much and how success can be measured are unknowns. It has become a matter of solidarity among nations not of policies with objectives. Not a single country (nor any politician nor any so-called climate scientist) has any inkling about what its climate policies will achieve for climate or even if it will achieve anything at all.

Some of the more savvy politicians and countries have figured out ways to seem to support political correctness while ensuring that their continued – and increasing – use of fossil fuels is not constrained in practice. For India and China the continued use of fossil fuels is critical and necessary for their growth. For the next 20  – 30 years, their carbon dioxide emissions are going to increase regardless of what the Paris meeting decides. India has proposed policies which seem – at first sight – to be drastic reductions in the “intensity of carbon dioxide emissions per unit of GDP” but defined in terms of growth such that coal consumption will have trebled in the next 25 years from 2005. India has now said it will cut emissions intensity by up to 25% of 2005 levels by 2020. China has also said it will reduce the intensity of carbon dioxide emissions per unit of GDP in 2020 by 40 to 45 percent compared with the level of 2005.

India’s GDP has grown from $0.8 trillion in 2005 to be about $2.1 trillion in 2014. China’s GDP has already grown from $2.3 trillion in 2005 to $10.3 trillion in 2014. These “promises” based on GDP are not even going to be legally binding  and there is certainly no cap to the GDP which can be aimed for or achieved. The GDP targets for India and China inherently require a mix of fuels to be used for electricity generation; coal, gas, nuclear and hydro primarily. Solar and wind power may have a large installed capacity and may contribute something to the growth but are not necessary or critical. The Indian and Chinese plans for using more gas and nuclear in their mix automatically brings down the carbon intensity per GDP from the levels of 2005 when both countries were heavily dependent on coal. Their coal plans can therefore proceed unimpeded while still meeting their “promises”. Both countries are relying on GDP growth to effectively reduce their “intensities of carbon emission” without having to reduce the rate at which they increase planned fossil fuel use or carbon dioxide emissions. Both India and China have reached the stage of development where electricity consumption growth is now lower than GDP growth. Both are at low levels of energy utilisation efficiency such that significant demand side improvements can be made. With around 7% growth in India and even with China reducing to, say, 6% growth, the reductions of intensity of carbon dioxide emissions per unit of GDP are impossible to prevent.

Any agreement in Paris will mean India trebling and China doubling its coal burn by 2030. And with “official” sanction to do so. So what “success” in Paris means is that global, man-made, carbon dioxide emissions are going to double (at least). And it also means that any carbon dioxide emission reductions promised by other countries are of no significance whatsoever. It is a very good thing that man-made, carbon dioxide emissions have no significant impact on global temperature.

And the Paris conference is both meaningless and irrelevant.

Japan to help Eastern Europe to shift from gas to coal

April 29, 2014

A return to coal as reality bites. It is now a “good thing” to help Eastern Europe to shift from Russian gas to their own coal.

Perhaps it is beginning to sink in that while carbon dioxide emissions have increased substantially in the last 20 years there has been no impact on global temperature. There is just no direct evidence that man-made carbon dioxide emissions have any significant impact on global temperature or on climate. The entire edifice of climate politics is built on this one unproven – and now broken – assumption. Take away this single assumption and all of climate politics collapses in a sorry heap.

Yomiuri Shimbun:

The government plans to support Ukraine and other Eastern European nations in the construction of next-generation coal-fired power plants that can generate power with less fuel, according to informed sources.

Under the initiative, Japan would stand behind the nations’ efforts to use coal—abundant in Eastern Europe—instead of natural gas, the supply of which makes them dependent on Russia. The government is expected to announce the initiative at the meeting of energy ministers from Japan and other Group of Seven industrialized nations to be held in Rome from May 5.

Japan’s support will involve the construction of coal-fired power plants using technologies known as supercritical steam pressure and ultra supercritical pressure to spin the turbines, enabling these nations to obtain electricity while using less fuel and emitting less carbon dioxide.

With a power generation efficiency of 40 percent to 43 percent, Japan has the world’s most advanced technologies in this field. About one-fourth of the coal-fired power plants in the nation use these technologies.

In comparison, Germany has a power generation efficiency of about 38 percent, while the corresponding figures for Ukraine and other Eastern European nations apparently remain at the 30 percent levels. 

If an agreement is reached with Ukraine, Japan will support a feasibility study to rebuild power plants during the current fiscal year. Under the initiative, Japan will provide yen loans to cover several tens of billions of yen in construction costs in addition to its energy-saving technologies, while Ukraine will provide emission quotas for greenhouse gases to Japan under their bilateral framework.

The G-7 meeting of energy ministers will discuss policies to raise the energy self-sufficiency rates of Ukraine and other European nations, as well as diversifying their energy supplies with one goal in mind: lowering their dependency on natural gas and oil from Russia.

 Ukraine imports 60 percent of the natural gas it uses from Russia, while the three Baltic nations and Eastern European nations buy from 60 percent to 100 percent of their natural gas from that country—a situation that makes it difficult to shift away from their reliance on Russia.

Though they have a dearth of natural gas, Eastern European nations have rich reserves of coal, with Ukraine being almost self-sufficient in that resource. Introduction of the next-generation coal-fired power plants is likely to improve their energy self-sufficiency rates, the sources said.

Young coral reefs will be unaffected by any ocean acidification due to increased carbon dioxide

August 14, 2013

Well now!

pH scale : Wikipedia

While I have no belief in the fanciful theory that man-made carbon dioxide emissions will have any significant effect on global warming, I have no doubt that an increasing carbon dioxide concentration in the atmosphere will lower the pH of the ocean (and they will only be more acidic in the sense of reducing alkanity though with a pH remaining well over 7.0). In fact it is likely that oceans will maintain a pH over 8.0 even in the worst scenarios. (Liquid solutions are usually described as acidic with a pH of less than 7.0 and as alkaline with a pH over 7.0 though on the continuous pH scale any reduction of alkanity is per force an increase of acidity and vice versa).

A new paper shows that the hypothesised catastrophic scenarios about ocean “acidification” (more correctly – a reduction of alkanity) and the consequent effects on coral reefs are little more than fantasy because they find that “there will be no direct ecological effects of ocean acidification on the early life-history stages of reef corals, at least in the near future”.

CM Chua, W Leggat, A Moya, AH Baird. Near-future reductions in pH will have no consistent ecological effects on the early life-history stages of reef coralsMarine Ecology Progress Series, 2013; 486: 143 DOI:10.3354/meps10318

Abstract: Until recently, research into the consequences of oceanic uptake of CO2 for corals focused on its effect on physiological processes, in particular, calcification. However, events early in the life history of corals are also likely to be vulnerable to changes in ocean chemistry caused by increases in the atmospheric concentration of CO2 (ocean acidification). We tested the effect of reduced pH on embryonic development, larval survivorship and metamorphosis of 3 common scleractinian corals from the Great Barrier Reef. We used 4 treatment levels of pH, corresponding to the current level of ocean pH and 3 values projected to occur later this century. None of the early life-history stages we studied were consistently affected by reduced pH. Our results suggest that there will be no direct ecological effects of ocean acidification on the early life-history stages of reef corals, at least in the near future.

ScienceDaily:

Corals can survive the early stages of their development even under the tough conditions that rising carbon emissions will impose on them says a new study from the ARC Centre of Excellence for Coral Reef Studies. …. 

Dr Andrew Baird, Principal Research Fellow at the ARC Centre of Excellence for Coral Reef Studies and James Cook University, was part of the research team and explains their findings.

“The prevailing view is that ocean acidification will act like a toxin to corals, but we were unconvinced by results from previous work on young corals and ocean acidification so we tested critical early stages of development in several coral species at several different acid (or ‘pH’) concentrations of seawater.

“Our results showed no clear response to increasing ocean acidification in any of the stages, or for any of the coral species,” says Dr Baird. “In fact, in only one of nine experiments did we get the response expected if CO2 was acting like a toxin. More often than not we found no effect.”

By bubbling CO2 through seawater the research team was able to simulate future levels of ocean acidification expected to result from rising human carbon emissions. They tested the success of embryo development, the survival of coral larvae and finally their success in settling on coral reefs.

The rest of the reporting by ScienceDaily is almost embarassing as they try to pay lip-service to the orthodoxy of the “the carbon dioxide is evil” fantasy. They waste space in trying to emphasise that even if young corals are not affected this “study does not discount the possibility that coral larvae may suffer other ill-effects from increasing ocean acidification, for example, their swimming speeds may slow down, but because coral larvae typically settle on the reef two or three weeks after birth it is unlikely that these effects will have a major impact on the survival or settlement of coral larvae”.

Three decades of needless “green” energy has cost some 15 million jobs in Europe

June 2, 2013

It has been a pointless waste. Just to pander to the superstition that controlling carbon dioxide emissions can control global temperature.

Temperatures have been flat since 1997 while human emissions of carbon dioxide have risen around 30%. Carbon dioxide concentrations in the atmosphere have also increased but have had little impact on global temperature – if any at all.

The last three decades have seen the vilification of carbon dioxide and the combustion of fossil fuels but it has been a pointless and expensive exercise. The profligate subsidies in favour of renewable energy and the shameless taxation of fossil fuel use and the consequent increase of energy prices have made their contributions to the economic slowdown and loss of jobs – particularly in Europe. The cowardly adoption of political correctness and of “green” energy is proving expensive – and has been quite needless.

Today electricity prices in Europe are at least 50% higher and perhaps twice as high as they need to be. The curbing of fossil fuel use and the hysteria about nuclear power together with the renewable profligacy are responsible for that. The cost of electricity is a fundamental parameter in our economies which feeds its way into every aspect of economic activity. It is the availability of affordable electricity which has been the driver of growth for over 100 years. A simple estimate of the growth that has been prevented by having unnecessarily high electricity prices gives the cost as being about 15 million jobs within the European Union.

Gerald Warner writes in The Scotsman: (my emphasis)

…. As the bottom falls out of the man-made climate change industry, those who were among its most bullish investors at the height of the scam are now covering their positions in a bear market.

Great damage was done to this much-hyped imposture by Climategate (“Hide the decline!”), by the discredited “hockey stick”, by the farce over “melting” Himalayan glaciers and the “decrease” in the polar bear population from 5,000 in 1970 to 25,000 today. Yet what has chiefly discredited the climate change superstition is the basic, inescapable fact that there has been no global warming since 1997.

The official face-saving response is that this is a “pause” in an otherwise menacing trend – a pause of a decade and a half. The warmist fanatics will freeze to death in their solar bunkers before they will admit defeat; but the more worldly wise, especially scientists anxious to preserve a vestige of academic credibility, are now striving to effect a withdrawal in good order.

Even the Intergovernmental Panel on Climate Change began to ratchet down its more extravagant predictions as early as 2007. In 2010 the Royal Society reviewed its stance on the Anthropogenic Global Warming theory and assumed a more neutral position. Since then, it has been like the retreat from Moscow: last month Oxford scientists, albeit in Delphic language, moderated forecasts of climate disaster. …..

….. The global warming hysteria began in the 1880s but was discredited when its prediction that CO2 would increase the mean global temperature by more than 1C by 1940 was not borne out. What gave it fresh life over the past two decades was the realisation by governments that it could provide a pretext for taxing citizens to unprecedented levels and by private entrepreneurs that government subsidies could supply a dripping roast. Of all the damage that politicians have inflicted on the public, the “green” scam has been among the most extreme.

The Renewables Obligation, introduced in Scotland in 2002, was scheduled to end in 2027, by which time UK energy customers will have been robbed of £32 billion. It has now been extended to 2037 for new projects. By 2011 Ofgem confirmed that 10 per cent of every electricity bill went towards “renewables”. Proliferating wind turbines are blighting the landscape despite being a wholly inefficient source of energy. Turbines operate at just 24 per cent of capacity – for more than a third of the time at only 10 per cent – and conventional power stations have to remain in service as backup: two energy systems pointlessly working in tandem. ……

…… South of the Border a modicum of sanity has entered government thinking since UK energy minister John Hayes’ “Enough is enough” remarks. In England and Wales turbines are falling out of favour. 

Not so in Scotland. ……. 

Local objections to wind farms are routinely overruled by central government (that would be the listening, accountable Scottish Nationalist government). At the end of last year only ten out of Scotland’s 32 local authorities admitted to knowing how many wind turbines were sited in their areas.

They could cover every inch of Scottish soil with Martian whirligigs and the lights will still go out, due to the SNP’s refusal to replace Hunterston B, due to close in 2016, and Torness, closing in 2023. All this to satisfy a superstition: if all mankind stopped producing CO2 (try selling that idea in China and India), 96.5 per cent would remain. The climate Anabaptists will never recant, but their mad creed is doomed all the same.

Wind turbines and solar energy have their place in the energy mix we should use.  But not at the expense of fossil fuel and nuclear use.

Reuters gets it wrong again: If Chinese emissions have been higher than assumed then emissions have even less effect on climate than thought!

June 11, 2012

Reuters reports that Chinese carbon dioxide emissions may be some 20% higher than previously thought. But then the Reuters reporters (David Fogarty and David Stanway) and their editor Jonathan Thatcher get their knickers properly in a twist and conclude that this suggests that “the pace of global climate change could be even faster than currently predicted”.

Perhaps some bright schoolboy could point out to our intrepid reporters that if the change in B is supposed to be dependent upon the change in A and if the change in A is actually higher than assumed, then the change in B is less dependent upon the change in A than assumed.

Coal consumption increases almost 50% in 10 years and has no impact on global temperature

August 26, 2011

There is a clear disconnect between global coal consumption (and therefore carbon dioxide emissions) and global temperatures.

Of course we must take into account that these are only real data over the last 10 years and are not generated by computer models and have not been validated by the IPCC!!

Quote of the week at WUWT 22nd May 2011

“People underestimate the power of models. Observational evidence is not very useful,” adding, “Our approach is not entirely empirical.” John Mitchell, principal research scientist at the UK Met Office

P Gosselin at NoTricksZone has the “heretical” story:

Global Coal Consumption Jumps Almost 50% – Yet Global Temps Drop! 

recently released BP report here shows that global coal consumption has risen over the last 10 years by almost 50%. So wouldn’t you think that all those millions of tons of emitted CO2 (food for plants) as a result would drive the global temperatures up? Have temperatures risen along with all that extra coal burning?

No they haven’t. In fact they’ve dropped slightly over the same period. So go figure!

Coal consumption and global temperature: http://notrickszone.com

In the above chart the blue line shows global coal consumption, data taken here, Review of World Energy. According to the report, India and China alone are responsible for 90% of the world’s coal consumption increase, while renewable energy in the 2 countries plays nary a role. According to BP figures, global CO2 emissions rose 5.8% in the year 2010. ……..
