cardellini_scrTalkshop readers with good memories may remember the article I wrote back in 2012 on findings by Cardellini et al that volcanic soils emitted far more CO2 than previously thought (and are not included in IPCC carbon cycle inventories). The implication is that longer sunshine hours during the 1980s-90s may well have released a lot of sequestered CO2 from these soils, thus raising atmospheric levels. Which would mean humans are not responsible for all of the increase, as has long been assumed.

Now another article from Robert Wylie on Livescience.com raises the issue again:

Robin Wylie, is a doctoral candidate in volcanology, atUniversity College London. He contributed this article to LiveScience’s Expert Voices: Op-Ed & Insights.

The exploding hills really give the game away: We’ve always known the Earth is a smoker. The true extent of its habit, though, is only just beginning to surface.

Before the human species found its talent for pyromania, atmospheric levels of the Earth’s greenhouse superstar, carbon dioxide (CO2), were controlled, for the most part, by volcanoes.

Since our planet emerged from the debris which formed the solarsystem, some four and a half billion years ago, a lifetime supply of primordial carbon has been locked away in the mantle — against its will. Partnering with oxygen and smuggled as a dissolved gas in liquid rock, it breaches the surface at our planet’s volcanic airways: CO2, then, has been seeping into the planet’s atmosphere for as long as there has been one.

Until the end of the 20th century, the academic consensus was that this volcanic output was tiny — a fiery speck against the colossal anthropogenic footprint. Recently, though, volcanologists have begun to reveal a hidden side to our leaking planet.

Exactly how much CO2 passes through the magmatic vents in our crust might be one of the most important questions that Earth science can answer. Volcanoes may have been overtaken in the carbon stakes, but in order to properly assess the consequences of human pollution, we need the reference point of the natural background. And we’re getting there; the last twenty years have seen huge steps in our understanding of how, and how much CO2 leaves the deep Earth. But at the same time, a disturbing pattern has been emerging.

In 1992, it was thought that volcanic degassing released something like 100 million tons of CO2 each year. Around the turn of the millennium, this figure was getting closer to 200. The most recent estimate, released this February, comes from a team led by Mike Burton, of the Italian National Institute of Geophysics and Volcanology – and it’s just shy of 600 million tons. It caps a staggering trend: A six-fold increase in just two decades.

Research Paper Withdrawal by the Journal Advances in Space Research  

peer-reviewQ1: As succinctly as possible, could you tell me why you chose to publish this work under a pseudonym?

A1: We adopted pseudonyms as a measure of last resort as we could not get an unbiased and fair review from scientific journals under our real names. This is explained in more details in the attached letter we sent to the chief editor of the Journal Advances in Space Research (JASR) on Sep. 17, 2015. In brief, our real names became known to the climate-science blogosphere in 2012 when a poster, which we presented at an International Climate Conference in Denver in 2011, became available online and caused broad and intense discussions. When we later tried to publish elements of this poster as separate articles in scientific journals, we discovered that journal editors and reviewers would reject our manuscripts outright after Googling our names and reading the online discussion. The rejections were oftentimes justified by the journals using criticisms outside the scope of the manuscript at hand.  On two occasions, journal editors have even refused to send our manuscripts for review after reading the blogs and realizing the broader theoretical implications of our results, although the manuscript itself did not explicitly discuss any new theory. For example, our first paper was rejected 4 times by different journals while submitted under our real names before it was finally accepted by SpringerPlus after submitting it under pseudonyms.

Charon’s ‘red spot’ [image credit: space.com]


Scientists have discovered ‘atmospheric transfer’ taking place between Pluto and its binary partner Charon.

In June 2015, when the cameras on NASA’s approaching New Horizons spacecraft first spotted the large reddish polar region on Pluto’s largest moon, Charon, mission scientists knew two things: they’d never seen anything like it elsewhere in our solar system, and they couldn’t wait to get the story behind it, as Phys.org reports.

Over the past year, after analyzing the images and other data that New Horizons has sent back from its historic July 2015 flight through the Pluto system, the scientists think they’ve solved the mystery.

Ron Clutz takes a closer look at the latest attempt to demonise the trace gas carbon dioxide, which as biology tells us is essential to plant life.

Science Matters


The media are reporting stories with a new theme: More CO2 is bad for plant life. This flies in the face of biochemistry, but the activist motivation is clear: They want people thinking CO2 is bad in every way. They don’t want the warming scare undermined by the idea that CO2 along with warming actually helps plant life and agriculture.

The current stories are coming from researchers involved with an outdoor laboratory site called Jasper Ridge, affiliated with Stanford University, my alma mater and home to famous alarmist Stephen Schneider (deceased). The headlines are occasioned by a new paper appearing Sept. 5 in the journal Proceedings of the National Academy of Sciences, authored by Chris Field, director of the Stanford Woods Institute for the Environment..

Headlines Claim, Details Deny

Headlines and claims like those below are appearing this week, but as we shall see, the details do not support the conclusions…

Another climate mystery – this time the QBO – for scientists to get their teeth into, as the Mail Online reports.

For more than 60 years, atmospheric scientists have observed the consistent behaviour of a wind pattern known as the ‘quasi-biennial oscillation’ – a phenomenon that repeats every 28 months. But in late 2015, the long-reliable pattern suddenly changed. 

The winds have since returned to their normal course, and while no immediate effects were detected, astronomers are working to understand if this was just a one-time ‘black swan’ event, or a ‘canary in the coal mine’ signalling unseen conditions.

Why jetstream shifts might be linked to Arctic ice (among other factors) is not made clear, so we’re left wondering.

Scientists have discovered the cause of the recent run of miserable wet summers as they begin to unravel the mysteries of the Atlantic jet stream, reports Phys.org.

Researchers from the University of Sheffield and The Met Office have identified a number of possible factors that may influence the Atlantic jet stream and therefore help to predict summer climate from one year to the next.

Of course the people behind the CFC ban are patting themselves on the back, but the role of other variables in the atmosphere may have been ignored or overlooked. Extracts from a BBC News report follow.

Researchers say they have found the first clear evidence that the thinning in the ozone layer above Antarctica is starting to heal.

The scientists said that in September 2015 the hole was around 4 million sq km smaller than it was in the year 2000 – an area roughly the size of India.

ScienceDaily reports on the latest advances in understanding how the solar wind interacts with Earth. Note the seasonal aspects and the electric current findings.

A team of National Science Foundation (NSF)-supported researchers at the Virginia Polytechnic Institute and State University (Virginia Tech) discovered new evidence about how Earth’s magnetic field interacts with solar wind, almost as soon as they finished installing six data-collection stations across East Antarctic Plateau last January.

Their findings could have significant effects on our understanding of space weather. Although invisible to the naked eye, space weather can have serious, detrimental effects on modern technological infrastructure, including telecommunications, navigation, and electrical power systems.

The researchers for the first time observed that regardless of the hemisphere or the season, the polar ionosphere is subject to a constant electrical current, produced by pressure changes in the solar wind.

Artist’s view of 55 Cancri e [credit: Wikipedia]


Unusual atmospheric data from this exoplanet: not much heat transfer from the side permanently facing its star to the dark side, giving it a ‘large day–night temperature gradient’.

The orbit period is only 18 hours, as it’s much nearer to its star than Mercury is to the Sun. It may also have ‘an unknown source of heat’, as Phys.org reports.

An international team of astronomers, led by the University of Cambridge, has obtained the most detailed ‘fingerprint’ of a rocky planet outside our solar system to date, and found a planet of two halves: one that is almost completely molten, and the other which is almost completely solid.

The Role Of Ozone In The Earth’s Climate

Erl Happ explains: To understand how climate evolves we have to comprehend the ‘ozonosphere’.

NOT A LOT OF PEOPLE KNOW THAT

In the 1920’s the inventor of the Dobson Spectrometer designed to measure ozone in the atmosphere, Gordon Dobson, quickly discovered that total column ozone maps surface pressure. Low pressure cells generated in high latitudes have fewer molecules in the atmospheric column because the upper portion is ozone rich, ozone absorbs infrared radiation from the Earth and the upper air is therefore more rarefied. The reduction in density aloft fully, and in fact over-compensates, for the coldness and density of the air at the surface. By contrast High pressure cells are dense above and relatively less dense below because they originate in the warmer ozone poor mid latitudes.

The ozone content of the air varies on all time scales.

Because the distribution of ozone is a secondary determinant of atmospheric pressure (along with the absorption of radiant energy from the sun as the primary determinant) its distribution is allied to wind…

Earth and Planetary Science Letters Has an interesting paper in the works. A new proxy informs a model which finds bigger than expected swings in CO2 linked to smaller than expected temperature swings in the past five million years. This indicates that the Earth’s climate system is less sensitive to CO2 levels than previously thought. Maybe they should take more notice of Leaf Stomata calibrations than Antarctic ice cores?

CO2 over the past 5 million years: Continuous simulation and new δ11B-based proxy data

Abstract
During the past five million yrs, benthic δ18O records indicate a large range of climates, from warmer than today during the Pliocene Warm Period to considerably colder during glacials. Antarctic ice cores have revealed Pleistocene glacial–interglacial CO2 variability of 60–100 ppm, while sea level fluctuations of typically 125 m are documented by proxy data. However, in the pre-ice core period, CO2 and sea level proxy data are scarce and there is disagreement between different proxies and different records of the same proxy. This hampers comprehensive understanding of the long-term relations between CO2, sea level and climate.

Reblog from Clive Best’s site.

The basis of IPCC predictions is that any moderate warming caused by increased CO2 levels is enhanced by more evaporation from the oceans. Water vapour is itself a strong greenhouse gas and this increase results in a large “positive feedback” boosting climate sensitivity to a doubling of CO2 as high as 6C.
This is all just  theory however, so it is important to observe whether water vapour in the atmosphere has actually increased or not in response to increasing CO2. The data shown below are from the NASA NVAP [1] project based on radiosonde, TIROS,TOVS & SSM/I satellite based data. This data was kindly brought to my attention by Ken Gregory [2].

Fig 1: total Precipitative water vapour in 3 levels in the atmosphere im mm. The 3 curves are Northern Hemisphere, Southern Hemisphere and the “Global average” – see 2) below.


The data from NVAP shows little change in  water vapour from 1988 until 2001 at all levels in the atmosphere.  If anything a  small decrease in the important upper atmospheric layers  in the detail shown below Fig1b.

Solid data on global cloud cover seems hard to come by, but NASA’s Deep Space Climate Observatory (DSCOVR) could be changing that. SpaceRef reports.

From a dusty atmosphere stretching across the Atlantic Ocean to daily views of clouds at sunrise, a new NASA camera keeping a steady eye on the sunlit side of Earth is yielding new insights about our changing planet.

With NASA’s Earth Polychromatic Imaging Camera (EPIC), affixed to NOAA’s Deep Space Climate Observatory (DSCOVR) about one million miles from Earth, scientists are getting a new view of our planet’s clouds, land surfaces, aerosols and more.

NASA instrumentation shows ‘the quietest solar minimum since the space age began’, as phys.org reports.

Observations made by NASA instruments onboard an Air Force satellite have shown that the boundary between the Earth’s upper atmosphere and space has moved to extraordinarily low altitudes.

These observations were made by the Coupled Ion Neutral Dynamics Investigation (CINDI) instrument suite, which was launched aboard the U.S. Air Force’s Communication/Navigation Outage Forecast System (C/NOFS) satellite on April 16, 2008.

a quote from “The Nonsense That is Ozone-Depletion”
by Ken Ring (2009) at http://www.ourcivilisation.com/ozone/king.htm
erebusOne Hole is Larger than the Other
Let’s look at one last factor, so often reported; that the Antarctic hole is larger than the Arctic one. One would think that even if inert heavier-than-air substances could make it up into space, that they would do it more around the densely populated regions of earth — the northern hemisphere; and affect the Arctic Hole more than the Antarctic. No one is disputing that the hole over the Antarctic is definitely much bigger. The Southern hemisphere has a longer winter than the Northern hemisphere because Earth is further from the sun in July than in January. Longer winter means bigger hole. But also maybe, some chlorine is coming from some other source, instead of CFCs. Let’s look around.

Aha! Just a few miles upwind from the Antarctic camp where all the readings about ozone-depletion originate from, is a rather large hill called Mt Erebus.
