Evidence here from researchers of shorter oceanic cycles than expected. They say ‘The general message is that all parts of the ocean surface are connected on surprisingly short time scales’, which could be ‘just 10 years’.

A new angle on glaciations perhaps, but HeritageDaily quotes one of the researchers: ‘The mechanism driving these expansions of southern sourced water into the deep Atlantic still needs working on.’

The North Atlantic Ocean played a key role in the last great tipping point in Earth’s climate system, pioneering new research has shown. An international research team has discovered ground-breaking new reasons why large continental ice-sheets first grew in North America and Scandinavia during the late Pliocene Epoch era, 2.7 millions of years ago.

Researchers claim to have ‘discovered a cycle of heating and cooling at the surface of the ocean’ in the North Atlantic which is modulated – so to speak – by winds, although they are also quick to make the obligatory nod in the direction of assumed future ‘global warming’.

Shifting winds may explain why long-term fluctuations in North Atlantic sea surface temperatures have no apparent influence on Europe’s wintertime temperatures.

Indulging in climate fantasy can lead to some strange ideas, like this one. The idea of articles like this is presumably to infect the minds of the gullible with thoughts of impending crisis, where none should exist.

With sea levels rising and Antarctica’s temperatures well below freezing, some people [i.e. the authors?] have raised the question: What would happen if we took water out of the oceans and pumped it onto the icy continent to freeze?

A group of scientists put that question to the test in a new study that explores the physical possibility and economic feasibility of geoengineering climate solutions in the future.

Between January 9 and February 4 this year, 29 sperm whales got stranded and died on English, German and Dutch beaches. Climate Change Dispatch investigates.

Environmentalists and the news media offered multiple explanations – except the most obvious and likely one: offshore wind farms. Indeed, that area has the world’s biggest concentration of offshore wind turbines, and there is ample evidence that their acoustic pollution can interfere with whale communication and navigation.

Somebody seems to have re-discovered the carbon cycle, and true to form the BBC is keen to spread the word by trying to relate it to buses and jumbo jets.

The seas around the UK and the rest of northern Europe take up a staggering 24 million tonnes of carbon each year. It is a mass equivalent to two million double-decker buses or 72,000 747 jets. The number was produced by scientists studying the movement of carbon dioxide into and out of the oceans.

H/T to Paul Vaughan for pointing to a series of comments by Bill Illis on wuwt, which describe and differentiate between the under-ice salt induced sinking which forms Arctic deep water and the Greenland-melt surface waters which flow into the Gulf Stream. These were in response to an alarmist paper which claims that increased freshwater flux could weaken the AMOC and thus global circulation.

Bill Illis responds:

And the salinity in the ocean in the area in question has changed by exactly ZERO. The paper doesn’t address this issue one iota.

The AMOC starts under the sea ice throughout the entire Arctic Ocean basin. Somehow climate scientists have convinced themselves that the deep water formation of the AMOC is next to Greenland. There is no way to correct them because they don’t actually care what the facts are, just what gets them published in the climate theology field.

The sea surface temperatures in the Norwegian Sea range from +2.0C to +10.0C.

The Arctic Bottom Water is -0.5C to -1.0C and is 3000 metres deeper. it has nothing to do with the Nowegian Sea.

The Arctic Bottom Water overflows the canyons and chokepoints out of the Arctic Ocean basin, particularly the Fram Strait canyon, the Denmark Strait and the Greenland-Scotland Ridge.

acid-bath

How scary is “ocean acidification”?  Very  scary. The previously scary “global warming” stopped 19 years ago, but do stay scared because all that CO2 since 1997 has instead been “acidifying” the oceans. Please imagine baby oysters dissolving in the equivalent of battery acid, and hermit crabs raising a nervous feeler to discover that their protective shells have disappeared. Curse you, horrible human-caused CO2 emissions!

In one celebrated episode involving Climate Science™,  a lone oyster farmer in Maine put his oysters into  a bucket and then found that the bivalves at the bottom were crunched because their shells were weakened.[1] Can any reasonable person ask for better  scientific proof of ocean “acidification”?

New Year is a traditional time for taking stock, getting rid of old stuff, and planning for the future. The climate advice from the talkshop is; Don’t sell your coat. As the current El Nino falters, we can expect cooler weather ahead for a couple of years from later in 2016.

Fig 1. Global temperature series from the two satellite datasets. The big El nino events in 1998 and 2010 were both followed by downturns. The 2015 El Nino will also be followed by a downturn in temperature.

Ian Wilson correctly forecasted the 2015 El Nino using his lunar technique and I also correctly forecasted it using my solar technique. Our observations of past events tell us is that  we are now likely to see a period of cooling, once the current El Nino dies down.

My thanks to Per Strandberg for this update on his ENSO modelling effort. This is looking good, and is based on a neural network which uses lunar and solar data for its input.

ENSO-solar-tidal-impact

There are two main drivers of ENSO. ENSO stands for El Niño Southern oscillation and is Earth’s most influential weather phenomena after seasonal changes. When ENSO changes it causes changes in currents and of temperatures in the tropical Pacific Ocean.

The most important ENSO driver is linked to variations in gravitational tidal forcing associated with Moon’s Perigee. Moon is in what is called Perigee, when the Moon is at it closest point during its elliptical orbit around Earth. This is also when the tidal force caused by the Moon is at its strongest.

The second most important forcing is linked to variation in solar activity.

My thanks to Tom Wysmuller for sending me this pithy one pager that he’s asked to have handed out as a flyer in Paris.

No Link Between CO2 & Sea Level! NONE!!!
Tom Wysmuller© 5 Nov 2015 http://www.colderside.com

For the past 2,000 years, Sea Level rise was unchangingly linear, increasing between 1 & 1.5 mm/yr., and CO2 was stable and flat at 280 parts per million (ppm) for the same period. The great Ice Sheets from the last Ice Age had already melted.

Additional Sea Level change was slow, mostly due to thermal expansion of oceans and edge ice melt from Greenland and Antarctica. As Earth periodically warmed and cooled, remaining mountain glaciers either grew or added some melt water to the oceans.

In 1880, CO2 finally surges up, achieving a huge 38% increase during the past 135 years, likely due to industrial and agricultural development.

Most seacoasts either rise or fall, due to geological activity. Some do neither, and are “tectonically inert.” Actual Sea Levels, and any changes, are measured from them, such as Portland, Maine, USA, and Wismar, Germany, where Sea Level continues its methodical, steady, minimal, and linear rise. In the timeframe that CO2 massively increases, there is no sign whatsoever that Sea Level reacts likewise.

I’m presenting the Doctoral thesis written by Harald Yndestad for his degree as Doctor of Philosophy at the Norwegian University of Science and Technology. This work is highly relevant to our investigation of the effect of Lunar cycles on climatic variation.

Preface

The research for this thesis began in 1996. The purpose was to confirm or reject the hypothesis that the life history of Northeast Arctic cod can be explained as a stationary cycle in a time series. I was rector at Aalesund University College from 1997 to 2000 and my research had to wait. In 2000 and 2001 I developed dynamic models for the most important species in the Barents Sea. The results supported the analysis from my first investigations. The next step was to look for the missing link between the 18.6-year lunar nodal cycle and the identified cycles in the Barents Sea. In 2001 I started to develop new methods to analyze climate indicators. The result was the Arctic Oscillation system theory. Wavelet analysis showed promising results and I started to analyze the biomass time series using the same analysis methods. This opened the possibility of a unified theory to explain the results from all time series.

coral_reef_and_tropical_fish

In the fable about the boy who cried wolf the villagers quickly decided the boy was lying and ceased to respond to his alarms. It seems modern day journalists must be much more gullible than those ancient villagers. Every year for almost a half­century the news media have breathlessly reported alarmist claims of imminent threats to the existence of the Great Barrier Reef. Despite the fact that all have proved to be fictitious, trivial or short lived fluctuation of nature, the phony alarms never seem to lose credibility with news reporters or even provoke any investigation.

The latest such instance has involved uncritical propagation of alarmist claims regarding the threat from some additional dredging of an existing dredged shipping channel in connection with expansion of the coal loading terminal at Abbott Point in central Queensland. (See: BATTLE FOR THE REEF, reported by Marian Wilkinson and presented by Kerry O’Brien, broadcast on ABC 4 Corners Monday 18 August 2014) Only a modicum of investigation would reveal that all of the ports along the Queensland coast have been dredged and require periodic re­dredging to maintain their entrance channels. The GBR itself is many km offshore and no detriment to the reef attributable to coastal dredging has ever been documented. A scattering of low diversity inshore reefs does occur in the region but these are restricted to rocky outcrops where wave action prevents sediment build­up and these reefs are comprised of a limited range of silt tolerant coral species.

A new study by the University of Cambridge ‘finds’ (their word) that changing climate in the polar regions can affect conditions in the rest of the world far quicker than previously thought. The full paper has paywalled access only, but by their own admission they say they are ‘only beginning to understand’ the processes they believe they have found.

A new study of the relationship between ocean currents and climate change has found that they are tightly linked, and that changes in the polar regions can affect the ocean and climate on the opposite side of the world within one to two hundred years, far quicker than previously thought.

This type of restriction was also imposed due to the ‘super El Niño’ of 1998, inviting comparisons with what’s happening to El Niño this season. No doubt various claims will be made about the causes. BBC News reports:

The Panama Canal Authority says it will temporarily cut the size of ships allowed through because of drought caused by El Niño. From 8 September, the maximum draft of ships will be cut to 39ft (11.89m), which may affect up to 20% of traffic. A similar restriction was imposed for the same reason in 1998.

The authorities say a further cut in the draft could be imposed on 16 September if the situation does not improve.The authority has taken the action because water levels in the Gatun and Alhajuela lakes has reduced as a result of the El Niño weather phenomenon. The current draft limit is 39.5ft, which will be cut to 39ft on 8 September and then potentially to 38.5ft on 16 September. Shipping companies had been warned the cuts could be coming.

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.

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

Planet Earth or Planet Ocean? Ron Clutz offers a water-based model.

Science Matters

I recently came across this comment:

“During the height of the day at the equator, 1361 joules/m2/second (less 30% Albedo) is coming in from the Sun but the surface temperature only increases as if 0.0017 joules/m2/second is absorbed (or impacts the temperature at 2 meters). The extra 959.9983 joules/m2/second flows away from the surface effectively almost as fast as the energy is coming in.

Your calculator says surface temperatures should increase to 87C.

At night, virtually no radiation is coming in (and the upwelling less downwelling radiation) says the surface should be losing about 100 joules/m2/second but it actually only loses 0.001 joules/m2/second.

This is the real-world now versus the theoretical.” Bill Illis

And then Derek John posted this:
