Hurricane Florence–The Myths and The Facts

.
The blog post title speaks for itself. Alarmists can’t accept natural variation, so use false logic to try and claim that any weather characteristic which wasn’t exactly like the last few hurricanes must be somehow man-made.

True to form, the media have been whipping up a state of hysteria about Hurricane Florence. Unlike some of their more irresponsible members, I have waited until all of the data is in, instead of rushing to judgment.

So, to the facts:

US ‘monster’ hurricane set to strengthen

Right on cue at the peak of the Atlantic hurricane season, three major storms are barrelling westwards. So far, the first one looks like being the most powerful. Mandatory evacuations for more than a million people near the US east coast have been declared.

North Carolina’s governor warns the state Florence will be a “life-threatening, historic hurricane”, reports BBC News.

Hurricane Florence – the most powerful storm to threaten the Carolinas in nearly three decades – is expected to strengthen, say forecasters.

Ocean tide size linked to supercontinent cycle

A new tweak to tidal theory is proposed. The research team hopes that ‘understanding continental configurations and tidal strengths will impact the development of climate models’.

Daily tides are driven primarily by Earth’s rotation and the gravitational force of the moon on oceans, says Earth magazine.

However, in a new study in Geophysical Research Letters, researchers suggest that tidal magnitudes are also influenced, on longer timescales, by the size and shape of the ocean basins, and are therefore driven by plate tectonics.

Plate tectonics gives rise to the formation of supercontinents — massive aggregations of continental lithosphere — which form and break apart in cycles that last about 400 million to 500 million years. With the breakup of the last supercontinent, Pangea, about 180 million years ago, and the projected formation of a new supercontinent, known as Aurica, in about 200 million years, Earth is currently in the middle of a supercontinent cycle.

Because the size and shape of ocean basins impact ocean circulation and tides, researchers led by Mattias Green, a physical oceanographer at Bangor University in England, hypothesized that tides may be linked to the supercontinent cycle in a so-called supertidal cycle.

Current tides, particularly those in the North Atlantic, are very large, Green’s team noted because of tidal resonance, which occurs when ocean basins and continental shelves reinforce and amplify the natural oscillation of tides as they sweep back and forth across oceans. “So the tides are larger at present because the continents are configured the way they are.”

To model Earth’s future oceanic tides, the researchers used predictions of continental configurations for the next 250 million years, through when Aurica is predicted to form. Ocean basin size was the main factor considered in the modeling, but the team also accounted for the moon’s gravitational pull on the oceans, Earth’s axial tilt, and simplified ocean bathymetries for future plate tectonic reconstructions.

Simplification of these fine details does affect the team’s modeling, notes David Waltham, a mathematical geologist at the Royal Holloway University of London, who was not involved in the study. But the simplifications used likely do not change the overall results, he adds.

Green and his colleagues reported that global tides are likely to increase over the next 50 million years “due to an enhanced tide in the North Atlantic and Pacific at 25 million years, followed by a very large Pacific tide at 50 million years.”

‘An individual starfish can consume up to 6 square metres (65 sq ft) of living coral reef per year’ – Wikipedia. Over-population in some areas has damaged the local reef.

Robot drones are set to be tested underwater to protect the Great Barrier Reef from crown-of-thorns starfish, reports BT.com.

The autonomous RangerBot is able to spot the coral-eating starfish with 99.4% accuracy and kill them using a fatal injection.

Volcano eruptions at different latitudes impact sea surface temperature differently

Volcanic eruption

Interesting results from this research into where and how volcanoes might fit into the oceans/climate picture.

Volcanic eruptions are among the most important natural causes of climate change, playing a leading role over the past millennium, says Phys.org.

Injections of sulfate aerosols into the lower stratosphere reduce the incoming solar radiation, in turn cooling the surface.

As a natural external forcing to the Earth’s climate system, the impact of volcanic aerosols on the climate has been of great concern to the scientific society and the public.

In recent years, scientists have found that there is a relationship between volcanic eruptions and the El Niño-Southern Oscillation (ENSO) based on reconstructions and model simulations, which is manifested in increased/decreased sea surface temperature (SST) gradient over the equatorial Pacific.

Coral Bleaching Just As Bad In 18thC

Many believe the forces of climate alarm got Professor Peter Ridd fired for saying what he thought about the recovery powers of the GBR.

NOT A LOT OF PEOPLE KNOW THAT

By Paul Homewood

A new study finds that coral bleaching on the Great Barrier Reef is nothing new.

From the Evening Express:

Large-scale coral bleaching has raised concern about the future of the ecosystems and the impact their loss could have on biodiversity.

Dr Sebastian Hennige, researcher

The teams found the frequency of bleaching has increased since the 1800s and, despite corals’ ability to recover, there are fears they could now be approaching a “critical threshold”.

Dr Nick Kamenos from Glasgow’s School of Geographical and Earth Sciences said: “It’s clear in the core data we examined that bleaching has been occurring on the Great Barrier Reef for at least 400 years, but the frequency of bleaching events has increased markedly since the early 1800s and those events have affected 10% more corals since the late 1700s.

“We can see that corals have been able to acclimate and recover from past…

Diving robots find Antarctic winter seas exhale surprising amounts of carbon dioxide

Antarctica

Researchers describe this as ‘a major challenge to our current understanding’. The global carbon cycle model may have to be revisited.

More than 100 oceanic floats are now diving and drifting in the Southern Ocean around Antarctica during the peak of winter, reports Phys.org.

These instruments are gathering data from a place and season that remains very poorly studied, despite its important role in regulating the global climate.

A new study from the University of Washington, the Monterey Bay Aquarium Research Institute, Princeton University and several other oceanographic institutions uses data gathered by the floating drones over past winters to learn how much carbon dioxide is transferred by the surrounding seas.

Results show that in winter the open water nearest the sea ice surrounding Antarctica releases significantly more carbon dioxide than previously believed.

The blueprint for El Niño diversity

How much this research can aid ENSO predictions remains to be seen, but any advance in understanding is welcome.

A new study isolates key mechanisms that cause El Niño events to differ, says ScienceDaily.

Researchers found that the complexity and irregular occurrence of El Niño and La Niña events can be traced back to the co-existence of two coupled atmosphere-ocean oscillations, with different spatial characteristics and different frequencies.

A new research study, published this week by an international team of climate scientists in the journal Nature, isolates key mechanisms that cause El Niño events to differ amongst each other.

Thermodynamics 101: Compression increases temperature.

Question: If I had a container, full with air, and I suddenly decreased the volume of the container, forcing the air into a smaller volume, will it be considered as compression, will it result in an increase in temperature, and why?

Answer on Stack Exchange by Luboš Motl: Yes, it is compression and yes, it will heat up the gas.

If there’s no heat exchange between the gas and the container (or the environment), we call it an adiabatic process. For an adiabatic process involving an ideal gas (which is a very good approximation for most common gases), pV^γ is constant where γ is an exponent such as 5/3. Because the temperature is equal to T=pV/nR and pV/pV^γ=V^1−γ is a decreasing function of V, the temperature will increase when the volume decreases.

Macroscopically, the heating is inevitable because one needs to perform work p|dV| to do the compression, the energy has to be preserved, and the only place where it can go is the interior of the gas given by a formula similar to (3/2)nRT.

Cooling Ocean Air Temps

.
.
Despite warming due to atmospheric trace gases being a racing certainty according to the IPCC and like-minded theorists, evidence of it is getting ever harder to find.

Science Matters

Presently sea surface temperatures (SST) are the best available indicator of heat content gained or lost from earth’s climate system.  Enthalpy is the thermodynamic term for total heat content in a system, and humidity differences in air parcels affect enthalpy.  Measuring water temperature directly avoids distorted impressions from air measurements.  In addition, ocean covers 71% of the planet surface and thus dominates surface temperature estimates.  Eventually we will likely have reliable means of recording water temperatures at depth.

Recently, Dr. Ole Humlum reported from his research that air temperatures lag 2-3 months behind changes in SST.  He also observed that changes in CO2 atmospheric concentrations lag behind SST by 11-12 months.  This latter point is addressed in a previous post Who to Blame for Rising CO2?

The May update to HadSST3 will appear later this month, but in the meantime we can look at lower troposphere temperatures (TLT) from UAHv6…

The Most Powerful Evidence Climate Scientists Have of Global Warming…Rules Out CO2 as the Cause

.
.
One of the points made here is that ‘cleaner air has resulted in more visible radiation warming of the oceans, not CO2’.

CO2 is Life

Source

We have mentioned countless times on this blog that the warming oceans are evidence that CO2 is not the cause of global warming. To understand the climate you must first understand the oceans. The oceans control the global climate. As the oceans warm, they warm and alter the humidity of the atmosphere above them. The problem is, as we have pointed out countless times, CO2’s only defined mechanism by which to affect climate change is through the thermalization of LWIR between 13 and 18µ.

LWIR between 13 and 18µ doesn’t penetrate or warm the oceans. Visible radiation, mainly from the high energy blue end of the spectrum does. CO2 is transparent to incoming visible radiation. The energy stored in the atmosphere and land is insignificant when compared to the oceans. The oceans contain 2,000x the energy of the atmosphere, so small changes to the oceans can mean big changes…

Dusty rainfall records reveal new understanding of Earth’s long-term climate

Antarctic sea ice [image credit: BBC]

Have scientists been looking through the wrong end of the telescope, so to speak, regarding ice ages theory?

Ancient rainfall records stretching 550,000 years into the past may upend scientists’ understanding of what controls the Asian summer monsoon and other aspects of the Earth’s long-term climate, says EurekAlert.

Milankovitch theory says solar heating of the northernmost part of the globe drives the world’s climate swings between ice ages and warmer periods.

The new work turns Milankovitch on its head by suggesting climate is driven by differential heating of the Earth’s tropical and subtropical regions.

New study finds variations in global warming trend are caused by oceans

The headline from the source should perhaps mention that those ‘variations’ can include ‘no global warming trend’, or hiatus, as explained below.

New research has shown that natural variations in global mean temperature are always forced by changes in heat release and heat uptake by the oceans, in particular the heat release associated with evaporation, reports Phys.org.

Analysing data from six climate models that simulated future climate change scenarios for the last International Panel for Climate Change (IPCC) Report, which appeared in 2014, University of Southampton Professor Sybren Drijfhout has shown that in all cases variations in global mean temperature were correlated with variations in heat release by sensible and latent heat.

Are El Niños Fueled By Deep-Sea Geological Heat Flow?

Is there evidence of a cause and effect connection between geological forces and El Niño generation? A look at one theory.

The Next Grand Minimum

El Niño and La Niña weather patterns have a significant impact on California climate. This illustration shows the drought impacts.

Long-term La Niña periods have been associated with long-term droughts in the southwest lasting 200, 90 and 55 years. More specifically severe droughts from AD1021 to 1051, AD1130 to 1180, AD1240 to 1265, AD1360 to 1365.

I often wondered what was the controlling mechanism that generated long-term La Niña conditions with few La Niño conditions. Plate Climatology Theory may be one possible answer, the generation of La Niña events by undersea volcanic activity.

I found this article on Plate Climatology most interesting.

Geologically induced “Eruptive” warm burst that helps generate 2014-2015 El Nino.

New paper: Model falsifiability and climate slow modes

Image credit: NOAA @ Wikipedia]

Two professors question the validity of current climate modelling, pointing to a number of apparent difficulties.

New understanding of ultra-long timescales provides a new take on climate, says The GWPF.
– – –
A newly published paper in the journal Physica A suggests that there is an undiscovered universe all around us that we are too short-lived to perceive.

Authors Prof. Christopher Essex (Applied Mathematics, University of Western Ontario) and Prof. Anastasios Tsonis (Mathematical Sciences, University of Wisconsin-Milwaukee) explain that even without external influences (e.g. man-made carbon dioxide) the weather patterns change over very long timescales, locally and globally.

If some elderly person claims to recall summers, say, that were different when that person was a child, that may not be faulty memory. Just because summers seemed warmer or colder; spring or winter seemed sooner; more or less snow was recalled, it doesn’t follow that the climate system has changed in any meaningful way.

Prof. Essex explains, “Unlike the stable virtual ‘climates’ seen in computer simulations, corresponding real-world conditions aren’t stable at all. There are perpetual, natural, internal changes in play that take longer than human lifetimes to play out.”

James Annan, Syd Levitus and the 35% exaggeration of Ocean Heat Content rise

I ran across this interesting exchange recently. In it, James Annan, one of the IPCC authors who got Pattern Recognition in Physics shut down after we published our findings on the solar-planetary theory in it because he thought it was wrong, doesn’t seem as bothered to deal with errors by his fellow oceanographer Syd Levitus. Not even when it’s a whopper that has been costing the taxpayer billions due to the climate! panic! James and his colleagues have promoted for years.

James Annan did eventually write a short letter to the journal, but it went unpublished. The Levitus papers were never corrected, though later IPCC reports show a figure for 1955-96 closer to 13×10^22J than the 18×10^22J Levitus et al reported. The increase was actually caused by the reduction in cloud cover letting more sunshine through, as measured by the ISCCP. The latest graphs have also ‘disappeared’ the fall in OHC between 2003-9 measured by ARGO buoys and replaced it with a rise.

Ancient flood left its mark in the Mediterranean Sea

“We may be dealing with the one of the largest floods that ever occurred on our planet,” said the lead author of the study.

It was the most abrupt environmental change, at a planetary scale, since the end of the Cretaceous, says Discover magazine.

One of the largest floods in Earth’s history may have deluged the Mediterranean Sea more than 5.3 million years ago, leaving behind a mass of debris roughly the size of Greece’s largest island, Crete, researchers say.

Scientists investigated a roughly 640,000-year span of time starting nearly 6 million years ago when the Mediterranean became a hyper-salty lake.

This so-called Messinian salinity crisis “was the most abrupt environmental change, at a planetary scale, since the end of the Cretaceous — that is, a sudden mass extinction, including dinosaurs, due to a meteorite impact,” said study lead author Aaron Micallef, a marine geoscientist at the University of Malta.

There’s Ken Rice’s nonsense, and then there’s thermodynamics

Ken Rice, an Edinburgh University academic who selectively censors dissenting comments at his pro-AGW “and Then There’s Physics” propaganda blog, has another of mine in moderation:

tallbloke says:

Your comment is awaiting moderation.

March 12, 2018 at 10:02 am

OK, I’ll drop that subject and deal directly with the subject of your blog post.
You state that:

“If the Earth’s atmospheric pressure is to contribute to the enhanced surface temperature, then that would mean that the atmosphere would need to continually provide energy to the surface. It could only do this through the conversion of gravitational potential energy to thermal energy. This would then require the continual contraction of the Earth’s atmosphere.”

This quote demonstrates that you’ve fundamentally misunderstood Ned Nikolov’s hypothesis. He’s not positing a raised surface T due to an ongoing gravitational collapse producing a compression, generating heat which is then lost to space.

Atmospheric pressure produces a density gradient; i.e. it forces there to be more air molecules per unit volume at lower altitude than at higher altitude. Denser air intercepts and absorbs more of the sunlight passing through it than less dense air, producing more molecular collisions and excitation. It therefore holds more kinetic energy.The more kinetic energy it holds the higher its temperature will be.

New study: Cooling cloud cycle caused global warming hiatus

Is this how it works? [image credit: politics.ie]

An obvious problem with studies like this is that as soon as natural climate variation is invoked – to explain the lack of expected warming from so-called greenhouse gases – the argument that such gases could be a dominant factor in climate processes is then severely weakened to say the least. It is in effect an admission that such variations could cause warming as well as cooling. How long can a ‘hiatus’ last before it becomes the status quo?

Reinforcement of Climate Hiatus by Decadal Modulation of Daily Cloud Cycle
– By Jun Yin and Amilcare Porporato, Princeton University
H/T The GWPF

Based on observations and climate model results, it has been suggested that the recent slowdown of global warming trends (climate hiatus), which took place in the early 2000s, might be due to enhanced ocean heat uptake.

Here we suggest an alternative hypothesis which, at least in part, would relate such slowdown to unaccounted energy reflected or re-emitted by clouds.

North Pacific climate patterns influence El Niño occurrences

Another attempt to shed light on this recurring but tricky to predict climate phenomenon.

For decades, scientists have observed the phenomena known as El Niño and La Niña, says Phys.org. Both significantly impact the global climate and both pose a puzzle to scientists since they’re not completely understood.

Now, a new study clarifies some of the obscurity surrounding El Niño and La Niña, which together are called the El Niño Southern Oscillation (ENSO).
