Had enough of climate propaganda?


Last week EPA Administrator Scott Pruitt stated that: “I think that measuring with precision human activity on the climate is something very challenging to do, and there’s tremendous disagreement about the degree of impact, so no, I would not agree that it’s a primary contributor to the global warming that we see.”

I can only applaud Pruitt’s thoughtful comments, writes Alan Carlin.

But in fact there is not just uncertainty as Pruitt said, but actual evidence that there are no significant effects of rising human-caused emissions or atmospheric CO2 levels on global temperatures.

abracadabra-515x396The biomass problem, or fallacy, is well-known and media like The Times are finally catching up.

Britain is wasting hundreds of millions of pounds subsidising power stations to burn American wood pellets that do more harm to the climate than the coal they replaced, a study has found.

Chopping down trees and transporting wood across the Atlantic Ocean to feed power stations produces more greenhouse gases than much cheaper coal, according to the report.

It blames the rush to meet EU renewable energy targets, which resulted in ministers making the false assumption that burning trees was carbon-neutral.

Alan Carlin argues that the stability of the Earth’s climate within its two fundamental modes, glacial and interglacial, is underestimated or ignored by climate modellers in their desire to talk up supposed human-caused factors.

The UN IPCC reports on climate are truly unusual scientifically.

Without any serious discussion or even an attempt to point out their unusual nature, they try to convince readers that the basic nature of Earth’s climate has been radically changed after millions of years, all because one very minor constituent of the atmosphere has been increasing, as it usually does during interglacial periods in response to higher temperatures.

During this long period the basic nature of Earth’s climate can be characterized as bistability. In other words, Earth has had dual climate equilibria. One occurs during ice ages and the other during interglacial periods. Both are very stable except that Earth flips from the ice age equilibrium to the interglacial roughly every 100,000 years and flips back again after another 10,000 to 12,000 years.

History suggests that we may be close to the next flip into an ice age, the colder of the two bistability climates. This has enormous implications for humans and all life on Earh. But the upper “limit” on interglacial temperatures does not appear to have been breached in all that time.

Hard to see Germany’s mighty motor industry taking this lying down, even if it’s not law just yet. A bad case of ‘greenhouse gas disease’ in the minds of legislators?

Germany invented the gasoline engine and diesel engine. Now, Germany’s Bundesrat wants the internal combustion engine banned starting in 2030, says ExtremeTech. The resolution by one of Germany’s two legislative bodies (analogous to the US Senate or British House of Lords) isn’t binding, but it had bipartisan support.

It suggests the days of the internal combustion engine car are finite. Other code phrases in the resolution, once deciphered, suggest Germany wants to roll back tax credits favoring diesel engine cars, and push for further incentives to ramp up the sales of electric vehicles.

The trick for many countries at COP 21 is to talk a good game without committing to too much financial pain. Also China is building coal-fired power stations at a record rate even while world leaders are indulging in a big moan about CO₂ levels. Your Oil & Gas News questions whether China’s climate claims can be taken seriously.

The United Nations’ 21st Conference of the Parties (COP21), running in Paris from November 30 to December 11, 2015, will see China come under particular scrutiny, as the country is likely to propose CO₂ emissions reduction targets that others view as unrealistic, according to research and consulting firm GlobalData.

Warwick Hughes points to a very interesting and detailed article: ‘Albedo regulation of Ice Ages, with no CO2 feedbacks’ featuring a ‘secret ingredient’ – you’ll have to read it to find out more.

Guest article by Ralph Ellis who welcomes constructive feedback – some familiar ice ages charts put together in a way I have not seen.

Repost from the JPL website

This view combines information from two instruments on NASA's Mars Reconnaissance Orbiter to map color-coded composition over the shape of the ground in a small portion of the Nili Fossae plains region of Mars' northern hemisphere. This site is part of the largest known carbonate-rich deposit on Mars. In the color coding used for this map, green indicates a carbonate-rich composition, brown indicates olivine-rich sands, and purple indicates basaltic composition. Image credit: JPL

Scientists may be closer to solving the mystery of how Mars changed from a world with surface water billions of years ago to the arid Red Planet of today.

A new analysis of the largest known deposit of carbonate minerals on Mars suggests that the original Martian atmosphere may have already lost most of its carbon dioxide by the era of valley network formation.

“The biggest carbonate deposit on Mars has, at most, twice as much carbon in it as the current Mars atmosphere,” said Bethany Ehlmann of the California Institute of Technology and NASA Jet Propulsion Laboratory, both in Pasadena. “Even if you combined all known carbon reservoirs together, it is still nowhere near enough to sequester the thick atmosphere that has been proposed for the time when there were rivers flowing on the Martian surface.”

The BBC enthusiastically churns out another alarm-filled report on the supposed state of the climate, this time focussing on the oceans. But look closer and there are some awkward questions. First the report:

Scientists have warned that marine life will be irreversibly changed unless CO2 emissions are drastically cut.

Writing in Science, experts say the oceans are heating, losing oxygen and becoming more acidic because of CO2.

They warn that the 2C maximum temperature rise for climate change agreed by governments will not prevent dramatic impacts on ocean systems.

Any guesses how this one’s likely to go? The idea that humans can control temperature changes is about as absurd as the idea that they are the main cause of them, as large fluctuations in long-term climate records clearly show. The prospect of maximum temperatures being set by law is risible – but in theory it could happen.

Phys.org reports: Around 900 Dutch citizens on Tuesday took their government to court in a bid to force a reduction in greenhouse gas emissions and take action against climate change.

“We want the Dutch government to reduce greenhouse gas emissions by 40 percent by 2020 compared to 1990 levels,” said Majan Missema, head of rights group Urgenda which is coordinating the legal action.

The group says the case is the first in Europe in which citizens attempt to hold a state responsible for its potentially devastating inaction and the first in the world in which human rights are used as a legal basis to protect citizens against climate change.

The idea that shipping could be releasing heat from the oceans has not been discussed much before.

Science Matters

In response to my water world post, I was shown the wonderful phrase coined by Dr. Bernaerts:

“Climate is the continuation of oceans by other means”.

In was in 1992 he wrote in Nature appealing to the Rio conference to use the UN Convention on the Law of the Seas (UNCLOS) to better manage human impacts on the oceans, and thereby address climate concerns. Needless to say, that call fell on deaf ears.

He later elaborates: “Presumably science would serve the general public better when they would listen to Leonardo da Vinci (1452-1519) who said: “Water is the driver of nature”. Some say that nature rules climate, but water rules the nature on this earth, and the water on earth is so synonymous with the oceans and seas that it can be said: Climate is the continuation of the oceans by other means.”

Dr. Bernaerts is certainly a man worthy of…

The Guardian newspaper finally facing up to climate reality? Well, after a fashion. Their global warming can may have been kicked down the road for a while, that’s all.

The idea that natural variation could make temperatures go up as well as down is still not for discussion in their biased climate world.

H/T Lord Beaverbrook.

Guardian report: Manmade global warming over the past decade has probably been partly offset by the cooling effect of natural variability in the Earth’s climate system, a team of climate researchers have concluded.

The finding could help explain the slowdown in temperature rises this century that climate sceptics have seized on as evidence climate change has stopped, even though 14 of the 15 hottest years on record have happened since 2000.

The authors of the new paper describe the slowdown, sometimes called a global warming hiatus or pause, as a “false pause”. They warn that the natural cycles in the Pacific and Atlantic that they found are currently having an overall cooling effect on temperatures will reverse in the coming decades – at which point warming will accelerate again.

An article in the Daily Mail today piqued my interest. It trumpets empirical results which they say empirically confirm the theoretical CO2 greenhouse effect for the first time:

greenhouseeffect“Scientists have witnessed carbon dioxide trapping heat in the atmosphere above the United States, showing human-made climate change ‘in the wild’ for the first time.

A new study in the journal Nature demonstrates in real-time field measurements what scientists already knew from basic physics, lab tests, numerous simulations, temperature records and dozens of other climatic indicators.

They say it confirms the science of climate change and the amount of heat-trapping previously blamed on carbon dioxide.”

“These instruments, located at ARM research sites in Oklahoma and Alaska, measure thermal infrared energy that travels down through the atmosphere to the surface.

They can detect the unique spectral signature of infrared energy from CO2.

Other instruments at the two locations detect the unique signatures of phenomena that can also emit infrared energy, such as clouds and water vapor.

UPDATE: This post mistook the upper curve for CO2 in the figure 4 from Callendar’s paper, cropped by the Guy Callendar twitter account. It is actually 5yr smoothed temperature, as pointed out by commenter ‘berniel’ in comments. So the apparent ~2.5yr lag between the upper and lower curve is due to the smoothing of the temperature data. This doesn’t change the fact that CO2 lags temperature at all timescales, but does invalidate the analysis in this article.

Back in 1938, Guy Callendar wrote a paper “The artificial production of CO2 & its influence on temperature”. In it is a figure showing how they both rose in the early C20th. MET office PR man Richard Betts retweeted the Guy Callendar twitter account this morning.

Unlike more modern misrepresentations given by climate scientists, which spuriously splice the instrumental record from 1950 onto ice core records (with a large temporal mismatch), Callendar uses actual empirical measurements of airborne CO2. His data reveals something sceptics have frequently pointed up: Temperature changes lead CO2 changes. Check my annotation to Callendar’s plot below the break.

Third in a trilogy of guest posts from Ed Hoskins. This one looks at how much temperature would be reduced if we committed economic suicide.

Temperature reduction outcomes from de-carbonisation
Ed Hoskins MAarch (Cantab)  BDS (Lond).

To quantify what might be achieved by any political action for de-carbonization by Western economies, the comparative tables below show the remaining effectiveness of each 100ppmv tranche up to 1000ppmv, with the total global warming in each of the five diminution assessments.  These estimates depend on the calculations set out in the following associated essay:

https://edmhdotme.wordpress.com/2014/09/13/the-diminishing-influence-of-increasing-carbon-dioxide-co2-on-temperature/

The table below shows the likely range of warming arising from these divergent (sceptical and IPCC) views, (without feedbacks, which are questionably either negative or positive: but probably not massively positive as assumed by CAGW alarmists), that would be averted with an increase of CO2 for the full increase from 400 ppmv  up to 1000 ppmv.Screen Shot 2014-08-10 at 11.33.54The results above for countries and country groups show a range for whichever scenario of only a matter of a few thousandths to a few hundredths of a degree Centigrade.

One of the ‘Tablets of Stone’ in the argument for ‘Anthropogenic Global Warming’ is that human emission of co2 through the burning of fossil fuel is responsible for the increase in the atmospheric level of this trace gas since pre-industrial times, which now constitutes 0.039% of Earth’s atmosphere. It is claimed that this can be logically deduced and calculated and  there is no doubt we are the guilty species.

But there’s a problem…
