Most of the Recent Warming Could be Natural – Jennifer Marohasy

The author notes that ‘while mainstream climate science is replete with published proxy temperature studies showing that temperatures have cycled up and down over the last 2,000 years – spiking during the Medieval Warm Period and then again recently to about 1980 as shown in Figure 12 – the official IPCC reconstructions (which underpin the Paris Accord) deny such cycles.’

We could add ‘and then says the science is settled’.
– – –
After deconstructing 2,000-year old proxy-temperature series back to their most basic components, and then rebuilding them using the latest big data techniques, John Abbot and I show what global temperatures might have done in the absence of an industrial revolution, writes Jennifer Marohasy. 

The results from this novel technique, just published in GeoResJ [1], accord with climate sensitivity estimates from experimental spectroscopy but are at odds with output from General Circulation Models.    

According to mainstream climate science, most of the recent global warming is our fault – caused by human emissions of carbon dioxide.

Green energy dream backfires for historic German town

Image credit: The Local

It’s not the only place in the region to suffer but as The Local says ‘Staufen has really become a byword for failed geothermal drilling.’

A German town’s decision to invest in geothermal energy backfired badly after underground drilling went wrong and hundred of buildings began to fall apart.

Staufen, a town of 8,100 inhabitants on the edge of the Black Forest, envisioned a blissful new green energy future when work on the project began in 2007.

But when the drills hit groundwater, the pretty Baden Württenburg hamlet instead found itself in a battle for survival. More than 270 buildings have suffered fractures since the drills penetrated a layer of earth and struck groundwater in a yard right behind the town hall. 

“We’ve been in crisis mode for ten years,” Mayor Michael Benitz told news agency DPA. “It’s a slow-motion catastrophe.” A red banner that hangs from the damaged town hall proclaims: “Staufen must not fall apart”. 

But in some cases it almost already has.

An Inconvenient Deception: How Al Gore Distorts Climate Science and Energy Policy – Roy Spencer, PhD

Target practice

Target sighted..load…take aim…fire!

Al Gore has provided a target-rich environment of deceptions in his new movie, says Roy Spencer.

After viewing Gore’s most recent movie, An Inconvenient Sequel: Truth to Power, and after reading the book version of the movie, I was more than a little astounded. The new movie and book are chock-full of bad science, bad policy, and factual errors.

So, I was inspired to do something about it.

I’d like to announce my new e-book, entitled An Inconvenient Deception: How Al Gore Distorts Climate Science and Energy Policy, now available on Amazon.com.

Rechargeable zinc-air batteries zero in on lithium

Sydney, Australia

Sounds promising, but can these batteries make the leap from hearing aids to machinery in general? Developments – if any – awaited.

Zinc-air batteries are an enticing prospect thanks to their high energy density and the fact they’re made with some of the most common materials on Earth, says New Atlas.

Unfortunately, those advantages are countered by how difficult it is to recharge these cells. Now, a team at the University of Sydney has created new catalysts out of abundant elements that could see rechargeable zinc-air batteries vying with lithium-ion batteries in mobile devices.

Discovery could lead to new catalyst design to reduce nitrogen oxides in diesel exhaust

Diesel car engine

Diesels are in need of some good news after all the recent negative press. The researchers believe their findings are of ‘major environmental importance’.

Researchers have discovered a new reaction mechanism that could be used to improve catalyst designs for pollution control systems to further reduce emissions of smog-causing nitrogen oxides in diesel exhaust, as Phys.org reports.

The research focuses on a type of catalyst called zeolites, workhorses in petroleum and chemical refineries and in emission-control systems for diesel engines.

New catalyst designs are needed to reduce the emission of nitrogen oxides, or NOx, because current technologies only work well at relatively high temperatures.

“The key challenge in reducing emissions is that they can occur over a very broad range of operating conditions, and especially exhaust temperatures,” said Rajamani Gounder, the Larry and Virginia Faith Assistant Professor of Chemical Engineering in Purdue University’s Davidson School of Chemical Engineering.

“Perhaps the biggest challenge is related to reducing NOx at low exhaust temperatures, for example during cold start or in congested urban driving.”

Hybrid trucks to operate on ‘electric highway’ in Germany

Could be expensive, but similar systems have already been installed in Sweden and California. No overtaking?

The German state of Hesse is to build a 10km-long highway with overhead power lines that trucks can connect to at speed with a pantograph, reports Power Engineering International.

Siemens Mobility are to develop the line to supply electricity to hybrid trucks, which will then be able to operate twice as efficiently as they would when running on petrol or diesel.

The company said that a 40-tonne truck running for 100,000km on an eHighway would realise €20,000 in reduced fuel costs.

David Miliband’s Silly Dream of a Second EU Referendum

Ben Somervell points out the flaws in the call for a ‘second referendum’ on EU membership.

Ben Somervell's Brexit Blog

Here is the hyperlink to an article entitled “Miliband’s second referendum idea’s bananas” which I have just written for the “Comment Central” website. I have reproduced below the text of the article:

Former Foreign Secretary and former Labour leadership candidate, David Miliband, stated this week that he supports a second EU referendum and that he is trying to persuade MPs to fight for such a vote. Such a proposal is deeply flawed and does not wash with voters. This was shown in the fact that the Liberal Democrats’ (the only party to propose such a vote) vote share fell from 7.9 per cent in the 2015 General Election to just 7.4 per cent in the 2017 General Election. The party failed even to garner the support of the 22 per cent of voters who still think, despite the Brexit vote, that we should remain members of the EU and their…

Buildings to generate their own power with innovative glass blocks

Credit: Solar Squared

Leaving aside questions like cost, effectiveness and ease of replacement, the idea is that ‘the electricity generated will then be available to power the building, be stored or used to charge electric vehicles’.

Buildings could soon be able to convert the sun’s energy into electricity without the need for solar panels, thanks to innovative new technology, reports Phys.org.

Renewable Energy experts from the University of Exeter are developing a pioneering new technique that could accelerate the widespread introduction of net-zero energy buildings through the latest Building Integrated Photovoltaics (BIPV).

These products, similar to the solar tile created by Tesla, can become a part of a building’s architecture to generate electricity.

RSPB fights Scottish govt. backed Tay and Forth wind farm developments

From the Evening Express

The Scottish Government gave consent to four major wind farms in the Firth of Forth and the Firth of Tay in 2014, but the RSPB launched a judicial review.

The charity initially won a court victory but it was later overturned, clearing the development and prompting the RSPB to seek a further appeal.

Scotland’s Court of Session last month refused the application for the case to be sent to the Supreme Court, but the RSPB has now applied directly to the UK’s highest court.

The charity said it recognises the role renewable energy has in reducing emissions but the current project could lead to major declines in the population of gannets, puffins and kittiwakes.

Diesel-fuelled jet engines: what promises to power
SA this summer and next summer and ..

If South Australia were a novel, it would find itself a place amongst the classic tragic comedies.

For a while the bromance between its vapid Premier, Jay Weatherill and Californian carpetbagger, Elon Musk might’ve earned a place in the ‘rom/com’ category, as well.

However, now that Jay Weatherill is determined to keep the lights on this Summer and beyond using diesel fuelled jet engines – instead of powering SA with sunshine and breezes captured and stored lovingly in Musk’s mega-batteries – that romance is clearly at an end.

Los Angeles tests cooling pavement paint to beat heat

LA street [image credit: theatlantic.com]

Whether this is anything more than a gimmick remains to be seen. It’s described as an experiment ‘to reduce the heat island effect’.

Can a splash of gray pavement paint help combat global warming?

In Los Angeles, where summer temperatures regularly surpass 100 degrees Fahrenheit (38 degrees Celsius), workers are coating streets in special gray treatments in a bid to do just that, as Phys.org reports.

The City of Angels, home to four million people, is the first major city to test the technology. Normal black asphalt absorbs 80 to 95 percent of sunlight, while the gray “cool pavement” reflects it—dramatically lowering ground temperature and reducing urban street heat, advocates of the method say.

During a demonstration of the technique, Jeff Luzar—sales director at GuardTop, which markets the product—showed how applying the paint could drop street temperatures by about 12 degrees Fahrenheit after just one coat.

Panic over for Europe’s diesel makers as Mild-Hybrid technology comes to the rescue

European auto makers look like riding out the current panic over diesel engine health risks, fighting off a clamour for action by politicians and environmentalists, and despite some worrying projections by investment bankers, as Forbes reports.

New “mild-hybrid” technology will quickly fill the gap left by diesel’s precipitate decline, while a softening attitude from the European Union (E.U.) suggests city bans of this now derided technology might not be as ubiquitous as feared.

Met Office tiptoeing round the truth

Air time for climate change sceptic Lord Lawson, critical questioning of Al Gore and the stonewalling Met Office – is the BBC’s support for climate alarmism weakening?

Met Office can’t bear to give facts on hurricanes writes Andrew Montford in the GWPF Newsletter.

It’s normal when somebody like Nigel Lawson appears on the BBC, for the corporation to follow up by giving somebody from the green side of the equation a chance for an unchallenged response. I think this is something to do with the unique way it’s funded. 

Today was no exception, with yesterday’s exchanges between Lawson and Al Gore being given a going over by Roger Harrabin and Peter Stott from the Met Office.

Harrabin had been tasked with looking at the claims about the relative levels of subsidy for fossil fuels and renewables, and this was not too bad.

Algal biofuel dream turns out to be a damp squib

Credit: inhabitat.com

Another green dream has crumbled in the face of inconvenient reality, defeated by biology, as Yahoo News reports. Research shows it is neither commercially nor environmentally sustainable, unless the equivalent of three Belgiums and a mountain of fertilizer can be found.

Modern biofuels have been touted as a greener alternative to petrol and diesel since the early 1900s. It seems like a good idea on paper, and they do work – but their use and production doesn’t come without problems.

The first generation of biofuels – mainly ethanol made from plant crops – and second generation, derived from plant and animal waste streams, both had environmentalists and others concerned about the competition for land and nutrients between biofuels production and food production.

It was with a lot of hope, and hype, that production of the third generation of biofuels was started. Unlike their predecessors, these biofuels are derived from algae, and so in theory the food vs fuel dilemma of crop-based biofuels would be solved.

Fossil fuel oil and gas originated from ancient algae in large measure, so the concept here is to replicate the essence of the creation of fossil fuels, albeit accelerated and optimised with modern chemical engineering. It was claimed that using algae would be much more efficient than creating biofuels from terrestrial plants and that the technology would make use of poor quality land not able to grow other crops.

The Scottish wind-power racket

21st Century Scottish landscape

John Constable and Matt Ridley at Capx deliver the lowdown on how Scotland gets UK taxpayers to pay for its windfarms, even when there’s no wind – or too much wind.

Imagine a sausage factory – the luckiest, most profitable sausage factory in the world. Its machines crank out their sausages, and lorries carry them to supermarkets. So far, so normal.

But this particular factory makes as many sausages as the management and staff choose. If they feel like taking the day off, the lorries and shelves stay empty. If they want to go a bit wild, they sometimes make so many sausages that there aren’t enough lorries to take them away. Or they carry on cranking out sausages even if the shelves are already full.

And here’s the really amazing thing: even when the lorries can’t cope or there is no demand for sausages, the factory gets paid.

NASA admits it hasn’t been accurately measuring Earth’s radiation balance

In order to measure Earth’s radiation balance, accurate measurements of both incoming and outgoing radiation have to be made. NASA has been testing a new prototype satellite to measure outgoing radiation from Earth. Up until now, the error on this measurement is estimated to be around +/- 5Wm^2, which means any ‘global warming’ signal is lost in the error margin. This has meant scientists have had to rely on models for estimates.

Warm periods in the 20th century are not unprecedented during the last 2,000 years

Long-term natural climate variation just won’t go away, as this report at phys.org shows.

A great deal of evidence relating to ancient climate variation is preserved in proxy data such as tree rings, lake sediments, ice cores, stalagmites, corals and historical documents, and these sources have great significance in evaluating 20th century climate warming in the context of the last two millennia.

Prof. Quansheng Ge and his group from the Institute of Geographic Sciences and Natural Resources Research, Chinese Academy of Sciences, collected a large number of proxies and reconstructed a 2000-year temperature series in China with a 10-year resolution, enabling them to quantitatively reveal the characteristics of temperature change in China over a common era.

Why we need to leave the single market

Ben Somervell lays out a full and well supported case for leaving the single market on #Brexit

Ben Somervell's Brexit Blog

In this article, I will use the terms “single market”, “internal market”, “European Economic Area” and “EEA” interchangeably as they are all effectively synonyms. (The following article is a full significantly extended, revised and updated version of a much shorter article which I wrote for the “Comment Central” website which was, in turn an extended version of a 952-word article here which I wrote for the “Student Voices” website in July).

I originally thought that Theresa May’s Lancaster House speech in January (transcript here), her letter to the President of the European Council, Donald Tusk, invoking Article 50 of the Treaty of Lisbon (here) and the Government’s Brexit White Paper (here) had once and for all nipped the idea of continued single market membership after Brexit in the bud. However, since the Conservatives lost their parliamentary majority in the General Election this year, it…
