Time graticule at 10 days, data points at 12 hours. Surprisingly the July 1st hot period has vanished. Plots of other sites show a similar effect. The most frequent warm and cool periods of weather are brief and readily seen.

This computation will produce different values from the mean values computed from thermometer minimum and maximum data because data shape at other times is taken into account, min/max does not. The filter used is also windowed, leakage is negligible.

The Sunspots 2.0? Irrelevant. The Sun, still is.
By shaviv

After being asked by 5 independent people about the new sunspot number reconstruction and that it doesn’t show that the sun should have contributed any warming to the 20th century, I decided to write about it here. I have one word to describe it – irrelevant. It is also a good opportunity to write about new results (well, one that saw the light of day a few months ago) showing again that the sun has a large effect on climate. Yet, the world will still continue to ignore it. Am I surprised? No I’m not.

The day a Mexican farmer saw the beginnings of one of the seven natural wonders of the world – at least
according to CNN

On February 20, 1943, Dionisio Pulido was working in his cornfield just outside the Tarascan Indian village of Paricutin, Mexico. He and his family had spent the day getting ready for the spring sowing by clearing the field of shrubbery, putting it in piles and burning it. At about four in the afternoon, Pulido left his wife and moved to a different field so that he could set fire to a new pile. When he arrived he noticed something strange: on top of a small hill in the field a huge crack, over six feet wide and 150 feet (47m) long, had appeared in the earth. At first Pulido wasn’t concerned, the crack only looked like it was about a foot deep. As he was lighting the pile of branches, however, the sound of thunder rumbled across the field and the ground began to shake.

Paul Vaughan has produced a six page .pdf document crammed with the fruits of his research into the ways in which solar variation affects Earth’s climate. Several of the observations and concepts coincide with the work we have been doing here at the talkshop over the last six years to unravel the mysteries of solar system dynamics and their effect on Terrestrial variation. Paul has applied his stats and visualisation skills and thorough approach to referencing, including direct links to data. This has resulted in a landmark document which readers will find both useful and inspiring. It demonstrates the progress that has been made in solar-terrestrial theory, (with hints about the underlying planetary solar relations too).

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.

hu-obama-pokerGuest Post from Ed Hoskins:

In November 2014, to much fanfare, President Obama concluded an agreement with China on Climate. This was as a precursor to the major Paris climate conference in December 2015, where it is anticipated that a definitive and binding Climate agreement should be reached.  These notes follow through that 2014 agreement as far as it concerns future likely CO2 emissions up until the year 2030.

Essentially the agreement said that whilst Western Nations would be expected to reduce CO2 emissions substantially, China, India and the rest of the developing world would continue its CO2 emissions growth until at least 2030 to ensure that continuing enhancement of the living standards of their populations, and that only then China would limit further growth of its CO2 emissions.

Though appealing in its simplicity, the ocean conveyor-belt paradigm has lost luster over the years […] the ocean’s eddy field, unaccounted for just decades ago […] figures prominently in the dismantling of the conveyor-belt paradigm. Another player in this dismantling is the ocean’s wind field. The traditional assignation of surface ocean gyres to wind-forcing and overturning to buoyancy forcing has ignored the vital impact of winds on overturning pathways and mechanics. […] the conveyor-belt model no longer serves the community well […] because it ignores crucial structure and mechanics of the ocean’s intricate global overturning.

[…] wind forcing, rather than buoyancy forcing, can play a dominant role in changing the transport of the overturning […]

It was the scientific skeptics who bucked the ‘consensus’ and said the Earth was round.
By Richard McNider And John Christy Updated Feb. 19, 2014

In a Feb. 16 speech in Indonesia, Secretary of State John Kerry assailed climate-change skeptics as members of the “Flat Earth Society” for doubting the reality of catastrophic climate change. He said, “We should not allow a tiny minority of shoddy scientists” and “extreme ideologues to compete with scientific facts.” But who are the Flat Earthers, and who is ignoring the scientific facts?

ChristyMT_GL_102_Models

In ancient times, the notion of a flat Earth was the scientific consensus, and it was only a minority who dared question this belief. We are among today’s scientists who are skeptical about the so-called consensus on climate change. Does that make us modern-day Flat Earthers, as Mr. Kerry suggests, or are we among those who defy the prevailing wisdom to declare that the world is round?

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.

  • GC33H-07Atmospheric controls on northeast Pacific temperature trends and variations, 1900-2012
Wednesday, December 17, 201403:16 PM – 03:28 PM
    • Moscone West
    • 3005
    Over the past century, northeast Pacific coastal sea surface temperatures (SSTs) and land-based surface air temperatures (SATs) display multidecadal variations associated with the Pacific Decadal Oscillation, in addition to a warming trend of ~0.5 to 1°C. Using independent records of sea-level pressure (SLP), SST and SAT, this study investigates NE Pacific coupled atmosphere-ocean variability from 1900 to 2012, with emphasis on the coastal areas around North America. We use a linear stochastic time series model to show that the SST evolution around the NE Pacific coast can be explained by a combination of regional atmospheric forcing and ocean persistence, accounting for 63% of nonseasonal monthly SST variance (r = 0.79) and 73% of variance in annual means (r = 0.86).

    My thanks to Patrick Moore, co-founder and ex Greenpeace leader, and since 1986 ‘the sensible environmentalist’, for his permission to repost this article printed in the Australian recently. The name of Patrick’s own venture – Ecosense reflects his logical and humanist approach to the climate debate.

    Patrick Moore: We Need More Carbon Dioxide, Not Less

    patrickmoore6

    Australian politics has been more influenced by the climate debate than any other country. Yet Australia is responsible for only 1.5 per cent of global CO2 emissions. Perhaps this speaks of Australia’s extraordinary commitment to the international community. Yet Australia has threatened to hobble its own economy while much larger ­nations take a pass while making pious pronouncements.

    I am sceptical that humans are the main cause of climate change, and that it will be catastrophic in the near future. There is no scientific proof of this hypothesis, yet we are told “the debate is over”, the “science is settled”.

    My scepticism begins with the warmists’ certainty they can predict the global climate with a computer model. The entire basis for the doomsday climate change scenario is the hypothesis that increased CO2 due to fossil fuel emissions will heat the Earth to unliveable temperatures.

    Future low solar activity periods may cause cold winters in North America, Europe and Russia.
    Jarl Ahlbeck – Abo Akademi University, Finland

    Historically, low solar activity periods like the Dalton and Maunder Minima have been connected to cold winters in Europe. It seems very possible that the low solar activity forced areas of low pressures into a southern route or caused a negative Arctic Oscillation, AO, which in turn allowed cold air from the North Pole to flow across Europe. But can we obtain from real measurements that low solar activity really is able to do that?

    HT to the Hockeyschtick for spotting this essay from Marine Biologist Walter Starck at Quadrant Online. More scientists are coming out to call the alarmist position for what it is.

    Walter Starck: The Climate Scam’s Meltdown

    uksnowiceThe rent-seekers, opportunists, third-rate academics, carbon-market scam artists and peddlers of catastrophic prophecy can see the alarmist bubble deflating, so they’re trying harder than ever to sustain the scare. Problem is, Mother Nature isn’t cooperating.

    This doesn’t mean the climate change “debate” will stop, the news media will cease reporting weather as a dire threat, or that the true believers will no longer be obsessed by it. However, the ultimate arbiter, climate itself, has made clear its decision by ceasing to warm for over 18 years. Despite the ongoing use of fossil fuels, a proclaimed 95% certainty of 97% of scientists and the high-powered projections of the world’s most advanced climate models, the climate has refused to pay the slightest heed.

    Contrary to all the confidence and predictions of alleged experts, storms are no more intense nor frequent, while droughts, floods and sea levels have declined to confirm alarmists’ barely concealed hopes of disasters. The simple fact is that the alleged experts and their high-powered models were wrong. The climate has ceased to warm and, with little or no [enhanced] greenhouse warming, the entire theory of Catastrophic Anthropogenic Global Warming (CAGW), aka Climate Change (CC), aka Global Warming, aka Extreme Weather, is left with no basis.

    Writing from Australia Ian Wilson will be familiar to Talkshop regulars expounding his interest in astronomical connections with earth. He has three related recent articles and now a summary binding them together. Tim adds, the subject has a long history including false accusations of astrology by detractors; in this linked 1999 paper by a veteran scientist some of the origins and history is briefly mentioned and also that as data and computing power becomes available progress is being made. It mentions El Nino [paper see ref 1].  Strangers may need to get a conceptual understanding of the regular alignment of the earth moon and sun, where self evident effect on earth is the cyclic variation is ocean tidal height.

    1. A SUMMARY OF THE THREE PREVIOUS POSTS

    If you are unfamiliar with this topic you may wish to read the following three post in order to understand this current covering post.

    Observations of the Earth rate of spin (i.e. LOD) show that there are abrupt decreases in the Earth’s rotation rate of the order of a millisecond that take place roughly once every 13.7 days. These slow downs in spin occur whenever the oceanic (and atmospheric) tidal bulge is dragged across the Earth’s equator by the Moon. They are produced by the conservation of total angular momentum of the Earth, its oceans and its atmosphere.

I can’t do justice to presenting this work by illustrating this post with figures from the paper using my cellphone, but this a seriously impressive piece of work which Nicola generously shares with Talkshop readers via a link below the break.

    I’d not followed up on the saga of DMS, a reminder came up so I’ve dug out the tale up to 2003 or so. What then, can anyone add more? Because IPCC AR4 looks to me to be obfuscating. Best do a quick scan of the long article before dipping too deeply into links.

    “Dimethyl sulfide (DMS) or methylthiomethane is an organosulfur compound with the formula (CH3)2S. Dimethyl sulfide is a water-insoluble flammable liquid that boils at 37 °C (99 °F) and has a characteristic disagreeable odor. It is a component of the smell produced from cooking of certain vegetables, notably maize, cabbage, beetroot and seafoods.”
    And the smell of seaside. Stinky stuff is Sulphur.
    __ http://en.wikipedia.org/wiki/Dimethyl_sulfide

    Why mention this on the Talkshop?
    Ocean critters produce the stuff, a very complex situation.
    The C is produced from CO2. S probably from volcanoes. Predation of the critters is also involved etc. part of a food chain.  Sulphur is in short supply, so bad that farming often needs additional input wherein lies yet another sad tale of enviro own goals, perhaps too why volcanic soils are lauded as highly productive.

    Dated 2000

    • Abstract. Continuous measurements of atmospheric dimethylsulfide (DMS) have been performed over a 10-year period (1990-1999) at Amsterdam Island in the southern Indian Ocean. Atmospheric DMSranges from 5 to1930 parts per trillion by volume (pptv) and shows a clear seasonal variation with a factor of 20 in amplitude between its maximum in January (austral summer) and minimum in July-August (austral winter). Important deviations from the 10-year monthly mean as high as 100% have been detected, which could not be explained by changes in meteorology and/or oxidation capacity of the atmosphere. Comparison with a three dimensional (3-D) chemistry/transport model revealed that changes in the source strength of DMS as high as a factor of 2 were required to account for such DMS interannual variations. In addition, DMS variability was found to be closely related to sea surface temperature anomalies, clearly indicating a link between DMS and climate changes.
