A few days ago I tweeted this comment above some remarkable video of the Three Gorges Dam bypass sluices.
Among other people, this was picked up by Willis, the warmist at WUWT, who used it as an opportunity to attack the reality of the Sun-climate connection:

Researchers now want to ‘understand both the processes that excite the waves and the processes that act to damp the waves.’
– – –
A ringing bell vibrates simultaneously at a low-pitched fundamental tone and at many higher-pitched overtones, producing a pleasant musical sound, says Phys.org.
A recent study, just published in the Journal of the Atmospheric Sciences by scientists at Kyoto University and the University of Hawaii at Mānoa, shows that the Earth’s entire atmosphere vibrates in an analogous manner, in a striking confirmation of theories developed by physicists over the last two centuries.
In the case of the atmosphere, the “music” comes not as a sound we could hear, but in the form of large-scale waves of atmospheric pressure spanning the globe and traveling around the equator, some moving east-to-west and others west-to-east.
Each of these waves is a resonant vibration of the global atmosphere, analogous to one of the resonant pitches of a bell.
The basic understanding of these atmospheric resonances began with seminal insights at the beginning of the 19th century by one of history’s greatest scientists, the French physicist and mathematician Pierre-Simon Laplace.
Research by physicists over the subsequent two centuries refined the theory and led to detailed predictions of the wave frequencies that should be present in the atmosphere. However, the actual detection of such waves in the real world has lagged behind the theory.
Now in a new study by Takatoshi Sakazaki, an assistant professor at the Kyoto University Graduate School of Science, and Kevin Hamilton, an Emeritus Professor in the Department of Atmospheric Sciences and the International Pacific Research Center at the University of Hawaii at Mānoa, the authors present a detailed analysis of observed atmospheric pressure over the globe every hour for 38 years.
The results clearly revealed the presence of dozens of the predicted wave modes.

Several interacting exoplanets have already been spotted by satellites.
But a new breakthrough has been achieved with, for the first time, the detection directly from the ground of an extrasolar system of this type, reports Phys.org.
An international collaboration including CNRS researchers has discovered an unusual planetary system, dubbed WASP-148, using the French instrument SOPHIE at the Observatoire de Haute-Provence (CNRS/Aix-Marseille Université).
The scientists analyzed the star’s motion and concluded that it hosted two planets, WASP-148b and WASP-148c. The observations showed that the two planets were strongly interacting, which was confirmed from other data.
Before the last time I had to dive deeply into politics to defend the EU referendum result, I had an email conversation with Roy Spencer in an attempt to resolve the conflict between physicists like himself, who believe the radiative greenhouse theory is correct, but it’s effect small, and physicists like Ned Nikolov, who contend that the theory is fundamentally incorrect.
After a couple of to and fro emails I sent this response in Feb 2019, to which I never received a reply. It’s time we got this discussion back out in the open, because Boris’ green reset #netzero plan for the UK post Brexit and post pandemic is set to ruin our economy and cause untold suffering, deprivation, and death.
the lukewarmers have utterly failed to convince the fanatics that although they think their theory is correct (it isn’t, but that’s their misguided opinion), they’ve overestimated the magnitude of the effect.
It’s time they stopped supporting the fanatics by deploying false arguments against better theory which will exonerate CO2 and move the debate away from ridiculous and expensive ‘mitigation’, and forward to adaption to the effects of natural climatic change.

The presence of Planet Nine has been hypothesized to explain everything from the tilt of the sun’s spin axis to the apparent clustering in the orbits of small, icy asteroids beyond Neptune.
But does Planet Nine actually exist?
Browsing twitter recently I ran across this short video of a solar flare shot a few days ago.
After asking for some clarification on frame rate I was really intrigued.

Nasa launched a satellite to measure global heights in 2018 and spotted the rise after bouncing laser pulses against sheets of ice, says the London Evening Standard.
The study found that Greenland lost an average of 200 billion tonnes of ice per year, and Antarctica lost an average of 118 billion tonnes.
One billion tonnes of ice is enough to fill 400,000 Olympic-sized swimming pools.
A team led by researchers at the University of Washington compared the data with measurements taken by the satellite between 2003 and 2009.
The findings, published in the journal Science, found the loss of ice from Antarctica and Greenland outweighs any gains from accumulated snow.
NASA claims humans now have 50 times more influence on temperatures than the Sun, according to this report. But they don’t link to any supporting evidence so we’re back to alarmist assertions and numbers pulled out of the sky, as usual.
NASA has shut down a spacecraft that measured the amount of solar energy entering Earth’s atmosphere for 17 years, more than three times the mission’s original design life, reports Spaceflight Now.
The Solar Radiation and Climate Experiment, or SORCE, mission ended Feb. 25 after the spacecraft labored through battery problems for years until NASA could launch a replacement.

To go to the technical discussion, search for ‘Overview’.
Dr. Peter Ward explains at The Hill Greenhouse gases simply do not absorb enough heat to warm Earth Excerpts in italics with my bolds.
Science is not done by consensus, by popular vote, or by group think. As Michael Crichton put it: “In science consensus is irrelevant. What is relevant is reproducible results. The greatest scientists in history are great precisely because they broke with the consensus.”
The drive to demonstrate scientific consensus over greenhouse-warming theory has had the unintended consequence of inhibiting genuine scientific debate about the ultimate cause of global warming.
Believers of “the consensus” argue that anyone not agreeing with them is uninformed, an idiot or being paid by nefarious companies. The last thing most climate scientists want to consider at this point, when they think they are finally winning the climate wars, is the possibility of some problem with the science of greenhouse-warming theory.

This enormous star seems to be fading fast.
Jan. 10, 2020: One day, perhaps in our lifetimes, perhaps a million years from now, the red giant Betelgeuse will dim a little–and then explode. The resulting supernova will rival the full Moon and cast shadows after dark, completely transforming the night skies of Earth. No wonder astronomers are closely tracking the current “fainting of Betelgeuse.”
“Fainting” is an actual astronomical term. It means dimming, the opposite of brightening. And right now, Betelgeuse is definitely fainting.
Betelgeuse photographed by Brian Ottum of Animas, New Mexico, almost 4 years apart using the same telescope and observing methods.
Edward Guinan of Villanova University and colleagues caused a minor sensation last month when they reported “[Betelgeuse] has been declining in brightness since October 2019, now reaching a modern all-time low of V = +1.12 mag on 07 December 2019 UT. Currently this is the faintest the star has been during our…

Estimates used by climate scientists to predict the rate at which the world’s ice sheets will melt are still uncertain despite advancements in technology, new research shows.
These ice sheet estimates feed directly into projections of sea-level rise resulting from climate change, says Phys.org.
They are made by measuring how much material ice sheets are gaining or losing over time, known as mass balance, to assess their long-term health.
Snowfall increases the mass of an ice sheet, while ice melting or breaking off causes it to lose mass, and the overall balance between these is crucial.
Although scientists now have a much better understanding of the melting behaviour of ice sheets than they did in previous decades, there are still significant uncertainties about their future melt rates, researchers found.

July 2019 was probably the 4th warmest of the last 41 years, writes Dr. Roy Spencer.
Global “reanalysis” datasets need to start being used for monitoring of global surface temperatures.
We are now seeing news reports (e.g. CNN, BBC, Reuters) that July 2019 was the hottest month on record for global average surface air temperatures.
One would think that the very best data would be used to make this assessment. After all, it comes from official government sources (such as NOAA, and the World Meteorological Organization [WMO]).
But current official pronouncements of global temperature records come from a fairly limited and error-prone array of thermometers which were never intended to measure global temperature trends.
Our friends Ned Nikolov and Karl Zeller will be keen to see the data from the Chandrayaan 2 lunar mission scheduled for take-off next week. Among many other experiments planned, the rover will be measuring surface thermal conductivity – a key factor in estimating the global lunar surface temperature.
The daily mail reports:
India’s space agency is preparing to launch its ambitious Chandrayaan-2 mission next week which is set to land near the currently unexplored south pole of the moon.
Chandrayaan-2 will blast off from the Satish Dhawan Space Center at Sriharikota on the country’s south west coast at 2.51am (10.21pm BST) on July 15.

Earth’s magnetic field keeps weakening at a faster rate. Should we be concerned?
Earth’s magnetic field is getting significantly weaker, the magnetic north pole is shifting at an accelerating pace, and scientists readily admit that a sudden pole shift could potentially cause “trillions of dollars” in damage. Today, most of us take the protection provided by Earth’s magnetic field completely for granted. It is essentially a colossal force field which surrounds our planet and makes life possible. And even with such protection, a giant solar storm could still potentially hit our planet and completely fry our power grid. But as our magnetic field continues to get weaker and weaker, even much smaller solar storms will have the potential to be cataclysmic. And once the magnetic field gets weak enough, we will be facing much bigger problems. As you will see below, if enough solar radiation starts reaching our planet none of us will survive.
But now we are being told that data collected…

Saturn’s distinctive rings were observed in unprecedented detail by NASA’s Cassini spacecraft, and scientists have now used those observations to probe the interior of the giant planet and obtain the first precise determination of its rotation rate, reports Phys.org.
The length of a day on Saturn, according to their calculations, is 10 hours 33 minutes and 38 seconds.

Something strange is going on at the top of the world, a Nature article says.
Earth’s north magnetic pole has been skittering away from Canada and towards Siberia, driven by liquid iron sloshing within the planet’s core.
The magnetic pole is moving so quickly that it has forced the world’s geomagnetism experts into a rare move.

The idea that humans can ever know exactly what the temperature is or was, everywhere on Earth – including the vast oceans – all the time, is amusing but not much else.
Reification is the Fallacy of Misplaced Concreteness. It is a mental process by which someone comes to believe that an abstraction (idea or concept) is a material, physical object in the real world. Mike Hulme observes that many people are obsessing over global temperatures, not realizing they are abstractions and not things to be feared. He provides calm and sensible views regarding global temperature reporting. The post at his blog is Climatism and the Reification of Global Temperature. Excerpts in italics with my bolds.
Over the last 40 years global-mean surface air temperature – ‘global temperature’ for short – has gained an extraordinary role in the science, politics and public discourse of climate change. What was once a number crudely calculated through averaging together a few dozen reasonably well-spaced meteorological time series, has become reified as an objective entity that simultaneously measures Earth System behaviour, reveals the future, regulates…

Recent research suggests the volume of volcanic CO2 being emitted into the atmosphere is far greater than previously thought, challenging man-made warming, says ClimateChangeDispatch.
The cornerstone principle of the global warming theory, anthropogenic global warming (AGW), is built on the premise that significant increases of modern era human-induced CO2 emissions have acted to unnaturally warm Earth’s atmosphere.
Hi Brandon, What is the best estimate of the ratio of radiation to space taking place from CO2 relative to H2O?
Dunno Rog. MODTRAN could probably get you in the ballpark. This is CO2-only from 70 km looking down, more what I would expect an actual Nimbus retrieval to look like. http://climatemodels.uchicago.edu/modtran/
Although CO2 absorbs thermal radiation from the Earth, it emits more. Carbon dioxide is in thermal deficit in terms of radiative balance. Nitrogen and oxygen constantly feed CO2 with heat so that it maintains a temperature higher than its radiative equilibrium. CO2 is a coolant.

Well…it’s complicated. The available data is less than perfect, but the ‘natural variation option’ (so to speak) is still on the table.
The IPCC lowered their estimate of the impact of solar variability on the Earth’s climate from the already low value of 0.12 W/m2 (Watts per square-meter) given in their fourth report (AR4), to a still lower value of 0.05 W/m2 in the 2013 fifth report (AR5), the new value is illustrated in Figure 1. These are long term values, estimated for the 261-year period 1750-2011 and they apply to the “baseline” of the Schwabe ~11-year solar (or sunspot) cycle, which we will simply call the “solar cycle” in this post. The baseline of the solar cycle is the issue since the peaks are known to vary. The Sun’s output (total solar irradiance or “TSI”) is known to vary at all time scales (Kopp 2016), the question is by how much. The magnitude of short-term changes, less than 11 years, in solar output are known relatively accurately, to better…
