Have you seen the “contrails” that persist for hours, Bob?
Yes. And I see clouds that persist for hours. Both the same thing. Condensed water vapor.

Tyndall's Experiment was brilliant. He got his results before Boltzmann discovered the mechanism of gas heating. We really did not understand black body radiation until Planck using Boltzmann's statistical approach figured out what happens. When Tyndall did his experiment in 1859 no one know how gases could absorb and re-radiate heat. To fully understand this we need the photoelectric effect and Compton effect. This were not established until the 1920's. Tyndall was really way ahead of his time.

Wait until next February. That will change. During the winter it gets very cold in the Arctic.

The combustion of natural gas produces one half the CO2 per joule of energy released by combustion as does burning coal. So if all our coal burning generating plants were replaced by natural gas burning plants the a amount of CO2 produced would be cut by a half. In addition burning natural gas is cleaner than burning coal and burning natural gas does not produce the horrendous poisonous ash heaps that burning coal does. In the ash heaps you find heavy metals (lead, arsenic...) and trace amounts of fissile elements. When the rain wets the ash heaps heavy metal compounds are leached into the the soil and find their way to nearby aquifers.

Individual weather events, be they fair or foul do not give us much information on climate.
In the climate trade moving 30 years intervals over which temperature, humidity, and frequency of rain, drought is averaged. A 30 year average gives us a single climate point.
Weather is controlled by some form of chaotic dynamics. Read up on Ed Lorentz and the butterfly effect to get a grip on that. Chaotic dynamics manifests a extreme dependency on initial and boundary conditions. Please see: https://en.wikipedia.org/wiki/Chaos_theory That is why weather cannot be accurately predicted more than a week ahead.
Climate exhibits chaotic behavior but on a stretched time scale
How difficult is it to model and predict climate? On a scale of 1 to 10 producing a quantum theory of elementary particles is a +5 (the standard model) and climate is 9.9. One of the reasons that a faithful climate model is not forthcoming is that there is currently no know algorithm for computing the solution to the Navier-Stokes equation numerically at all necessary scales of resolution. Please see: https://en.wikipedia.org/wiki/Navier–Stokes_existence_and_smoothness
Climate not only involves temperature and humidity, but also the flow of matter from region to region. Thus a solution to the Navier Stokes equation is require.
If one wished to compare the development of climate science with the development of basic particle physics or equilibrium thermodynamics, it would be fair to say climate science has not achieved the level that dynamics and mechanics was at prior to Galileo and Newton. Or the level that Thermodynamics as at prior to Maxwell and Boltzmann.

The melting of the Arctic sea ice means the Northwest Passage will stay open long which mean more sea commerces can use this shorter route. It is good news for trade and business.

I think you are quoting me. Aikido doesn't work on me.
The Earth has been warming since the Little Ice Age. That's a true statement but has nothing to do with AGW which is getting a freebie ride off this undisputed fact.
As for Canada? The perma-frost goes soft. BFD! This is your problem and won't be dealt with by AGW BS. Fossil fuels Regina!
"Is the rest of the world warming?" has to do in the context of this yik yak with this century or the last 20 years.

More from Judy the denier who hates science and probably deserves to be killed:
https://judithcurry.com/2019/02/07/climate-hypochondria-and-tribalism-vs-winning/
Judith Curry is a top of the line atmospheric physicist and has written the basic text on Atmospheric thermodynamics. Curry does science. The Climatistas do models and poor models at that. The IPCC in its CMIP=5 bundle has produced shit. Humans do affect climate but the IPCC climatistas have not modeled climate anywhere near correctly. The difference between Curry and you is that she knows thermodynamics thoroughly and you don't.

Here is an item from the Front Porch that contains a fair bit of sense in its general scope:
Someone might ask: "What is the climate of city (or settlement or area X)?" Or, "How does the climate of city Y differ from the climate of city Z?"
There really is no global climate. There are regional climate regimes governed by latitude, topography, nearness to the oceans, the presence of forests and grasslands, etc. In general climate is warmer in the tropics which receive sunlight nearly directly than at the poles where the sunlight cames in aslant due to the tilt of the earth to the plane of the ecliptic. The climate subsystems interact because heat is transferred from the higher temperature regions to the lower temperature regions by the oceans and atmosphere.

The key to the warming effect of the greenhouse gases is the stephan-boltzmann law. The greenhouse gasses absorb heat and reradiate in all directions. Which means half the heat absorbed radiated downward . The effect of the greenhouse gasses is slow the rate at which energy in the infrared frequencies is radiated into space (which is the cold sink for Earth's heat). According to the stephan boltzmann law the temperature will rise until the outward flux of energy is equal to inbound flux of energy (from the Sun).

Today's "scientists" and spokesman for the "scientists"often seem to forget that. So often we hear from them that we don't have time to wait that long. We have to act now to save the planet, the universe, existence.

The Paleocene–Eocene Thermal Maximum (PETM), alternatively "Eocene thermal maximum 1" (ETM1), and formerly known as the "Initial Eocene" or "Late Paleocene Thermal Maximum", was a time period with more than 8 °C warmer global average temperature than today. The CO2 level was at 550 ppm. This was 55 million years ago. This very warm period lasted 200,000 years and did NOT produce an unstoppable warming. Life flourished subsequent to this period. Eventually the CO2 level and temperature levels went down and several million years of hard ice age and glaciation followed. If the PETM did not turn us into Venus, nothing we are doing now will.
Humans do not possess the technology to sterilize this planet. However there is little doubt that we could kill ourselves off if we set our minds to it. But no matter what we do, the Earth will remain an abode of life for the next billion years barring an exceedingly large celestial body colliding with Earth and busting the planet into little pieces.

And climate doom alarm mongers say exactly the same thing when weather doesn't support their doomsaying. When they feel that they can take advantage of weather as a scare tactic, they conveniently forget how caustically they scolded others on the distinction between weather and climate.
The meteorologists consider a 30 year running average of temperature, humidity, ghg levels. sea levels cloud cover as a climate data point. One day's weather doth not make climate. 30 years average weather is a climate data point.

Not quite a full Ayn Rand sighting, and only as fresh as a year old, but someone went to a lot of trouble to put this together. Those someones at the Foundation for Economic Education, as it turns out. Well, Jeffrey Tucker and Jennifer Grossman and a bad wig. Yes, that Jennifer Grossman.
I felt an involuntary cringe a couple of times, but that is probably witchcraft.

But absolutism belongs to philosophy. Philosophy came first and it is philosophy that science always repairs to for the certainty of inquiry that is possible, hence the philosopy of science and it's method.
--Brant
And philosophy will be absolutely unable to produce anything useful. Philosophy, by and large, is a failure at being useful. There are some minor exceptions in the field of epistemology. But in ethics, aesthetics, psychology it is useless. Metaphysics is beyond useless. It is a vacuum that sucks thoughts out of the heads of otherwise intelligent people.

Bob,
So metastatements are absolute?
(No need to reply seriously. I'm just busting your balls. )
Michael
It is not an absolute scientific statement. I don't think there are any such. The best physical science can mange are assertions so backed up by experiment that it would be unreasonable to doubt them in the absence of evidence that they might not be true. No reasonable person doubts the second law of thermodynamics at this time, but if evidence were found against it, we would have to reconstruct the physics of energy. The conservation of energy is similar in that fashion. No one doubts it, but it could, in principle, be empirically falsified. No scientific theory or hypothesis is beyond possible falsification. The is why physical science succeeds where philosophy fails.

Bob,
That's exactly my point. So shouldn't one be careful in making absolute statements of fact about the cosmos ending by entropy?
I believe a qualification is in order.
"If we use the entropy law, which until now has not been breached, and only that, the cosmos will end one day by entropy. And even then, this is according to the present level of knowledge, which is subject to change."
Michael
No scientific statement is absolute. Scientific conclusions are held provisionally as probable but nevertheless subject to empirical falsification. There statement "No scientific statement is absolute" is not a scientific statement. It is a metastatement, a statement -about- science.

There might be things which are not observable. We don't know.
You can't get your brain around the totality of existence with a "law." That's hubris. Scientists are modest---or should be. Conclusions should not outrun observations except to suggest avenues of inquiry.
---Brant
That is almost certainly true. We now have good evidence that space itself is is expanding and at an accelerating rate. Which means there are portions of the physical cosmos where the space is expanding at greater than the speed of light. This does not contradict relativity, which postulates that no local motion IN spacetime of a wave or object can be such that the local motion is at greater than light speed. Spacetime can expand (or at least is not forbidden by theory) at greater than light speed. Which means there may be portions of the physical cosmos which we can never see which means we can never know them.

Bob,
I look at it from a different angle.
When someone--states--as fact--that the cosmos sprang into existence with entropy ensuring its own destruction, I look to the beginning of the cosmos and wonder how anyone can know. From the knowledge we have at the present, we can say no human was there to observe.
And we have yet to tap into nonhuman intelligence, if such exists. And, even if that should ever happen, maybe we will only get some cosmic fake news about what went on in the beginning.
Michael
You may look to the beginning of things but you won't see them. You can only guess what there possibly were. There is just so far we can look back in time.

Bob,
In other words, the certainty of this law depends on human observation.
Correct?
And were humans around at the start of the cosmos?
Michael
As do all scientific laws. Any scientific law, hypothesis or theory is one empirical falsification away from being modified or discarded. That includes the second law of thermodynamics. However as physical laws go the second law of thermodynamics is a close to "a sure thing" as any physical law yet propounded. Put it another way. If the second law of thermodynamics is falsified, most of physics will come down with it. It was found out recently that certain neutrinos had small but non-zero mass. The standard model had to be modified slightly to accommodate this finding, but the Standard Model remained intact. If the second law is ever falsified then the Standard Model will come crashing down, although the General Theory of Relativity will remain intact. That is how central thermodynamics and the second law is to non-gravitational physics.

Bob,
Do you know enough about the start of the cosmos to make that statement?
All you know is what humans--at the present level of evolution--have observed.
Or do you believe humans stopped evolving?
Michael
Basic law of thermodynamics. Entropy increases. When entropy becomes maximum temperature everywhere is the same. No more work can occur. The so-called heat-death of the Universe. No exception to the second law of thermodynamics has ever been observed so if the second law is really true then the cosmos will reach a stage where nothing else happens. Heat death. It does not matter how the cosmos got started. The entropy is increasing.

Bullshit. Cirrus clouds persist for hours on end. The water trail from a jet is made of the same stuff as Cirrus Clouds. H2O in a solid state which occurs shortly after gaseous H2O condenses into liquid H2O. All the nasty gasses are invisible. SO2, NOx CO2.
