Data centre owners won’t like the idea of being at the mercy of unreliable power sources for their vital electricity. ‘Welcome to the energy crunch’ seems to be the message out of this report from Power Engineering International.

Data centres will consume 20 per cent of Ireland’s power generation capacity by 2025, according to the country’s main grid operator, Eirgrid.

Eirgrid added that the huge increase in data centre activity in the country would eat up to 75 per cent of growth in Irish power demand.

The Irish Independent reports that the amount of power needed to store emails, texts and other online data could rise seven-fold as Ireland chases inward investment from tech giants including Apple, Google, Amazon and Microsoft.

2017 eclipse path over US [credit: NASA — click on image to enlarge]


Time to go fishing for insights into eclipse phenomena, thanks to a loan of specialized US Navy comms equipment.

On Monday, just as CU Denver began the new academic year, an awe-inspiring solar eclipse captivated people across North America, reports Phys.org.

A thin line of total solar coverage spanned, at various intervals, the continental United States, completely blocking out the sun from Lincoln Beach, Ore., to Charleston, S.C., for a few remarkable minutes.

Mark Golkowski, PhD, acting chair and associate professor of Electrical Engineering in the College of Engineering and Applied Science at CU Denver, and several students collected data during this rare celestial event by using state-of-the-art Naval submarine communication technology.

homeworkReproducibility is a cornerstone of the scientific method. It must be possible to replicate experiments or datasets which scientific claims rest on. Especially when billions of pounds of public money financing public policy decisions stemming from those scientific claims are at stake. Here’s just one reminder of certain climate scientist’s approach to this fundamental aspect of scientific method and ethics.

We’ve lost the numbers: CRU responds to FOIA requests

The world’s source for global temperature record admits it’s lost or destroyed all the original data that would allow a third party to construct a global temperature record. The destruction (or loss) of the data comes at a convenient time for the Climatic Research Unit (CRU) in East Anglia – permitting it to snub FoIA requests to see the data.

The CRU has refused to release the raw weather station data and its processing methods for inspection – except to hand-picked academics – for several years. Instead, it releases a processed version, in gridded form. NASA maintains its own (GISSTEMP), but the CRU Global Climate Dataset, is the most cited surface temperature record by the UN IPCC. So any errors in CRU cascade around the world, and become part of “the science”.

Professor Phil Jones, the activist-scientist who maintains the data set, has cited various reasons for refusing to release the raw data. Most famously, Jones told an Australian climate scientist in 2004:

Even if WMO agrees, I will still not pass on the data. We have 25 or so years invested in the work. Why should I make the data available to you, when your aim is to try and find something wrong with it.

Back in late 2011, the Talkshop splashed the story on a ‘Unified Theory of Climate’  developed by PhD physicists Ned Nikolov and Karl Zeller. They set out to show that the ‘greenhouse effect’ is not a phenomenon arising out of the absorption and reemission of outgoing long-wave radiation by the atmosphere (as thought for 190 years), but is a form of compression heating controlled by solar radiation and the total atmospheric pressure at the Earth’s surface. Pressure is in turn a product of the gas mass contained in a column of air above a unit surface area, and the planet’s gravitational effect on that mass.

It’s been a long and treacherous road involving many revisions and refinements of the original study. On several occasions the manuscript was rejected unread, but Ned and Karl have finally got their greatly improved and expanded paper published. This latest version is a tour de force strengthened by the rigors of criticism from an army of peer reviewers at several journals along the way.

Using dimensional analysis (a classical technique for inferring physically meaningful relationships from measured data), they show that the long-term global equilibrium surface temperature of bodies in the solar system as diverse as Venus, the Moon, Earth, Mars, Titan and Triton can accurately be described using only two predictors: the mean distance from the Sun and the total atmospheric surface pressure. This type of cross-planetary analysis using vetted NASA observations has not been conducted by any other authors. It represents the first and only attempt in the history of climate science to assess Earth’s surface temperature in the context of a cosmic physical continuum defined by actual planetary-scale observations. The result is a new insight that planetary climates are independent of the infrared optical depth of their atmospheres arising from their composition, and that the long-wave ‘back radiation’ is actually a product of the atmospheric thermal effect rather than a cause for it.

Despite confessing to being ‘baffled by clouds’, climate science and its media followers are still prone to assertions like ‘as the world warms’ – as though it’s bound to do so indefinitely.

Though we see them every day, clouds remain such a mystery to scientists that they are inhibiting climate change predictions. But a new atlas could be a game changer, thinks DW.COM.

Nothing beats a lazy afternoon sitting on the grass and watching the clouds roll by. These white fluffy friends can feel like a constant and comforting presence in life. And since the dawn of air travel, as folk singer Joni Mitchell once sang, we’ve looked at clouds from both sides now.

But as Mitchell cautioned, somewhow we still don’t know clouds at all. Her words were true in 1969, and they are still true today.

The arguments stirred up by the NOAA’s ‘pausegate’ whistleblower rumble on. A UK Met Office expert asserted ‘the slowdown hasn’t gone away’. This one could run and run.

David Rose’s splendid and significant article in last week’s Mail on Sunday certainly caused a stir. The initial reaction, mostly distractions, have been easily dealt with by David Rose in this week’s installment.

One of the points raised concerned a paper submitted to the Journal of Climate by Huang et al. It is about the new ERSSTv5 sea surface temperature dataset.

It is an interesting paper that claims that ERSSTv5 shows a lower rate of warming than the previous ERSSTv4 which was used by the now famous Karl et al paper in 2015 which claimed that — contrary to the IPCC — there had been no slowdown in the rate of temperature increase in the past 15 years or so – the so-called Pause.

One persistent activist said the paper was stolen and it was unethical to comment on it. In reality the preprint was obtained from a public webpage, anyone could have downloaded it. It has been in circulation for weeks.

The Earth experienced two super El Ninos recently: 1997/1998 and 2015/2016. It was expected that 2016 would be the hottest year in the satellite record which begins in 1979. It was, but by only 0.02°C over 1998. That is not statistically significant according to Dr. Roy Spencer, keeper of the UAH satellite system data. (The margin of error is 0.1°C, much larger than the difference between the El Nino years.) The graph above shows the UAH results. A separate satellite analysis by Remote Sensing Systems (RSS) came to the same conclusion.

Satellites measure the temperature of the lower troposphere, the portion of the atmosphere where weather takes place. These measurements give a more realistic picture of global temperature than do surface measurements. Essentially, global temperature now is the same as it was nearly 18 years ago.

The earlier El Nino had a sharp drop off as a strong La…

Motoring in Norway

Motoring in Norway

Renewable energy has no hope of replacing the 90-odd million barrels of oil used daily around the world.

Robert Lyman looks at some of the inconvenient facts.

Friends of Science Calgary

Contributed by energy economist Robert Lyman @ July 2016

Environmentalists across Europe and North America seem determined to wage war on oil-fueled motor vehicles, including private cars, light trucks and heavier trucks used for freight. The most recent example of this is the announcement that Norway and the Netherlands, heavily influenced by the European Green Party, may ban car manufacturers from selling cars and light trucks fueled by gasoline or diesel fuel by 2025. It wasn’t enough to raise fuel taxes and carbon taxes to punishing levels; an outright ban was called for. The Environment Minister for Germany was quoted as saying that Germany might do the same, but quickly retreated from that after a strong public reaction.

This is all allegedly to “save the planet”, the often repeated mantra of those who believe in the theory that humans are causing catastrophic climate change and that this can be stopped…

Jean,

We (Mike H) have done a modest amount of work on degree-days for G-S. They
now want to extend this. They are involved in dealing in the developing
energy futures market.

G-S is the sort of company that we might be looking for a ‘strategic

for an hour on the afternoon of Friday 12 June (best guess for Phil & Jean

Goldman Sachs is an investment banking house with a long history of trying to influence democratically elected governments fiscal, energy and climate policy with its placemen. They lost a lot of cash in the 2007 banking crash, and now they want to cash in on the potential $20T ‘global carbon dioxide market’ to recoup their losses, and make some handsome profits.

14cH/T to ‘Scottish Sceptic’ for this story from SCMP.com

Radiocarbon dating, which is used to calculate the age of certain organic materials, has been found to be unreliable, and sometimes wildly so – a discovery that could upset previous studies on climate change, scientists from China and Germany said in a new paper.

Their recent analysis of sediment from the largest freshwater lake in northeast China showed that its carbon clock stopped ticking as early as 30,000 years ago, or nearly half as long as was hitherto thought.

From Science daily:

A new Yale-led study estimates that there are more than 3 trillion trees on Earth, about seven and a half times more than some previous estimates. But the total number of trees has plummeted by roughly 46 percent since the start of human civilization, the study estimates.

Using a combination of satellite imagery, forest inventories, and supercomputer technologies, the international team of researchers was able to map tree populations worldwide at the square-kilometer level.

A commenter on another site with the handle ‘Agent009’ has come up with an interesting formula for calculating the environmental lapse rate on three solar system bodies with atmospheres. Talkshoppers might offer some ideas as to why it works. H/T to Stuart ‘Oldbrew’ for flagging this one up.

I’ve been trying to solve a puzzle… dry adiabatic lapse rate is normally calculated as following:
Γ = g·M/cp
where Γ is lapse rate, g is surface gravity acceleration, M is mole mass and cp is molar heat capacity.
However, if you calculate this for Earth, you arrive at 9.77 K/km, but actual environmental lapse rate, as defined in the ISA, is 6.49 K/km, which is about 9.77 * 0.665. So, I decided to take a look at how this works on Venus and Titan – the only two other worlds in the Sol System that actually have tropospheres.
On Venus (assuming tropopause at 55 km), the average lapse rate is about 7.9 K/km, but the above formula gives you 10.46 K/km, which means that you must multiply the result by 0.756 to get the actual value. On Titan (assuming tropopause at 42 km), actual average lapse rate appears to be around 0.5 K/km, but predicted lapse rate is 1.26 K/km – which gives you the coefficient 0.427. So I’ve been trying to figure what this mysterious coefficient depends upon – and, I think, I’ve found it. The following expression gives you almost exactly those numbers (using SI units, that is):

³√(12·g·M·(1/R – 1/cp))
where R is the ideal gas constant.

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.”

Relevant to current discussions on the talkshop concerning changes in Earth’s length of day (LOD) and the effect of planetary orbital resonances on the Moon’s orbital parameters and Earth climatic variation; this is a repost from Ian Wilson’s excellent Astro-Climate-Connection website. Ian very generously opens with a hat tip to this blog, (at which he is one of the ‘collaborators’ he mentions). 

Connecting the Planetary Periodicities to Changes in the Earth’s LOD
Monday, October 14, 2013 : Ian Wilson PhD

[(*) Some of the findings in this blog post concerning the connection between the Earth’s rotation rate and the planetary configurations have also been independently discovered by Rog “Tallbloke” Tattersall and his collaborators]

A. The Connection Between Extreme Pergiean Spring Tides and Long-term Changes in the Earth’s Rotation Rate as Measured by the Rate-of-Change of its Length-of-Day (LOD). (*)

If you plot the rate of change of the Earth’s Length of Day (LOD) [with the short-term atmospheric component removed] against time [starting in 1962] you find that there is a ~ 6 year periodicity that is phase-locked with the 6 year period that it takes the lunar line-of-nodes  to re-align with the lunar line-of-apse [see the first note directly below and reference [1] for a description of the method used to determine the time rate of change of LOD].

NB: The pro-grade precession of the lunar line-of-apse once around the Earth with respect to the stars takes 8.8504 Julian years (J2000) while the retrograde precession of the lunar line-of-apse line-of-nodes once around the Earth with respect to the stars takes 18.6000 Julian years (J2000). Hence, the lunar line-of-apse and the ascending node of the lunar line-of-nodes will realign once every:

(18.6000 x 8.8504) / (18.6000 + 8.8504)  = 5.9969 Julian years

Science Daily reports on recent research by Oregon State University (H/T The Hockeyshtick):
A new study using evidence from a highly detailed ice core from West Antarctica shows a consistent link between abrupt temperature changes on Greenland and Antarctica during the last ice age, giving scientists a clearer picture of the link between climate in the northern and southern hemispheres.

Greenland climate during the last ice age was very unstable, the researchers say, characterized by a number of large, abrupt changes in mean annual temperature that each occurred within several decades. These so-called “Dansgaard-Oeschger events” took place every few thousand years during the last ice age. Temperature changes in Antarctica showed an opposite pattern, with Antarctica cooling when Greenland was warm, and vice versa.

In this study funded by the National Science Foundation and published this week in the journal Nature, the researchers discovered that the abrupt climates changes show up first in Greenland, with the response to the Antarctic climate delayed by about 200 years. The researchers documented 18 abrupt climate events during the past 68,000 years.

The vote in the Senate Environment and Public Works Committee came after the GOP-controlled House repeatedly approved the bill. It previous was stalled in the Democratic-majority Senate.

Under the measure, which President Obama has threatened to veto if the Senate passes it, the EPA would only be allowed to use scientific studies whose detailed results are posted publicly online.
