for - economic growth - physical limits to - reductio ad absurdum - physical absurdity of continuing current energy and waste heat trends into the near future
paper details - title - Limits to Economic Growth - author - Thomas W. Murphy Jr. - date - 21 July, 2022 - publication - Nature Physics, comment, online - https://doi.org/10.1038/s41567-022-01652-6
summary - Physicist Thomas W. Murphy employs reductio ab adsurdium logic to prove the fallacy of the assumptions of his argument - In this case, the argument is that we can indefinitely continue to sustain economic growth at rates that have held steady at about 2-3% per annum since the early 1900s. - Using both idealistic and simplified energy and waste heat calculations of energy and waste heat compounding at 2-3% per annum (or 10x per century), Murphy shows the absurd conclusions of continuing these current trends of energy and waste heat emissions on a global scale. - The implications are that physics and thermodynamics will naturally constrain us to plateau to a steady state economy in which the majority of economic activity needs to not depend on physically intensive

Another way to frame physicallimitations to growth is in terms of wasteheat, which is the end product of nearlyall energetic utilization on Earth.
for - absurdity of indefinite economic growth - waste heat projection example of recent waste heat trends
absurdity of indefinite economic growth - waste heat projection example of recent waste heat trends - At present, the waste heat term is about four orders of magnitude smaller than the solar term. - But at a growth factor of ten per century, they would reach parity in roughly 400 years. - Indeed, the surface temperature of Earth would reach the boiling point of water (373 K) in just over 400 years under this relentless prescription.

Die späte Hitzewelle in Frankreich in der zweiten Augusthälfte lässt sich mit großer Zuverlässigkeit auf die Emissionen von Treibhausgasen zurückführen. Sie wurde nur möglich durch die hohen Temperaturen der umgebenden Meere und die Trockenheit im Süden Frankreichs, die Folgen der globalen Erhitzung sind. Der Attributionsforscher Davide Faranda stellt im Gespräch fest, dass solche Hitzewellen bei weiterer Erhöhung der Temperaturen häufig vorkommen werden.

Die obersten 2000 m der Ozeane haben 2023 15 Zettajoule Wärme mehr absorbiert als 2022. Die Erwärmung dieser Schichten verringert den Austausch mit den kälteren unteren Schichten und belastet die marinen Ökosysteme dadurch zusätzlich. Bisher sind keine Zeichen für eine Beschleunigung der Zunahme des Wärmehinhalts im Verhältnis zu den Vorjahren zu erkennen. Die Oberflächentemperatur der Ozeane lag im ersten Halbjahr 0,1°, im zweiten Halbjahr aber für die Wissenschaft überraschende 0,3 Grad über der des Jahres 2022. Schwere Zyklone, darunter der längste bisher beobachtete überhaupt, trafen vor allem besonders vulnerable Gebiete.

The hottest days of the 2021 heatwave coincided with very low, early afternoon low tides throughout most of the Salish Sea (the inland waters of BC and Washington State). As a result, surface temperatures in excess of 50 °C were observed in the intertidal zone (Fig. 6a, b), particularly on gently sloping south and west-facing surfaces that received the most direct solar radiation.

Dr Lisa van Aardenne, the chief scientist of the University of Cape Town’s climate system analysis group, discussed the use and utility of thermal stress indices. She pointed out that, by the definitions of the universal thermal climate index, much of Africa is under heat stress most days of the year. Van Aardenne noted that these indices have been developed from a European perspective and do not align with the reality on the ground in Africa. She added: “I’m very concerned that these indices are not fit for purpose here.”
So for Africa, the figures are so bad that they always look like they're in an emergency? I'm guessing the impact would be that people are more likely to ignore them

Prof Kris Ebi from the University of Washington started off the third day of the conference with a presentation on heatwaves and early action plans. She pointed to the 2021 Pacific north-west “heat dome” event, which resulted in around 800 excess deaths and was later found to be a 1-in-10,000 year event. The rarity of that event means, in effect, “these people died because of climate change,” Ebi said. She added: “Every heat-related death is preventable.”
I hadn't realised the attribution was so clear like this. Wow.

Gould, cruising along Antarctica’s west coast, according to Carlos Moffat, chief scientist, Palmer Long Term Ecological Research Program: “Even as somebody who’s been looking at these changing systems for a few decades, I was taken aback by what I saw, by the degree of warming that I saw… We don’t know how long this is going to last. We don’t fully understand the consequences of this kind of event, but this looks like an extraordinary marine heatwave,”

Heat pumps – those powered by electricity, as well as those using fuel – have a significant potential for reducing the specific CO2 emissions for the heat supply in multifamily buildings. This potential is connected with special demands on both sides: the domestic hot water preparation and the heat transfer system (heat sink) as well as the utilization of environmental energy at site (heat source).

Splooting, or more technically heat dumping, is a process through which animals stretch their hind legs back and lie on cooler surfaces to reduce their body heat. It’s commonly done by squirrels and sometimes, by dogs, and it’s no reason for concern, it’s just a sign that the animal is hot and trying to cool off.

While heat pumps are the most cost effective way to use electricity to heat your home during the cooler months, leaving them running day and night is not economically efficient. According to Energywise, you should switch off your heat pump when you don’t need it. This is to avoid excessive energy waste.

“We need to find ways to meet our customers’ needs and ambitions of reducing emissions to remain relevant for them.
Énergir can, and should, meet their customers' needs by helping them to end their use of gas and by accelerating a managed decapitalization of their existing gas assets. Énergir should "Pump Heat, Not Gas." By this I mean, they should refocus as a "thermal-utility," rather than as a gas-supplier and build a new business focused on the installation of heat pumps and the provision of geothermal district heating for their customers.

will reduce overall natural-gas usage by about 70 percent in buildings that install them,
Quebec's plan to encourage hybrid heating (electric + gas) will cause a dramatic increase in gas bills:
Reducing the quantity of gas commodity consumed does not reduce the largely fixed costs of gas delivery. Thus, in order to ensure revenue neutrality and adequate utility cost recovery, a 70% reduction in the quantity of gas delivered will require a 333% increase in the per-unit cost of gas delivery. This increased cost will, of course, be offset by reduced expenditure on the gas commodity. However, If we make the reasonable assumption that today's costs are evenly split between commodity and delivery, a 70% reduction in gas consumption will require a new per-unit price of delivered gas which is at least 182% of the current price with a reduction to 8.25% of the commodity's share of costs. Gas consumers will be paying for pipes, not gas... (I'm not sure what todays cost split is in Quebec. If it's 60% delivery, the price will rise to 212% of today's cost. If it is only 40%, the price will rise to 151% of today's. )
However, it is likely that if the per unit cost of gas increases by the amounts calculated above, a great many gas users will realize that the cost/kWh or BTU of heating with electric heat pumps is lower than that for gas. Thus, it is likely that gas abandonment will increase over the current rates. While environmentalists will welcome increased gas abandonment, it should be recognized that it will create additional pressure to increase the per-unit cost of gas delivery which will, of course, encourage even more abandonment. The result will be a gas death-spiral.
The Quebec approach is unlikely to lead to good outcomes.

a report identifying the climate strategies and technologies that will result in the most air and water quality improvements
One would expect such a report to say much about reducing emissions from electricity generation, however, in many states, particularly those in the Northeast and North, electricity generation and use only produces a small portion of GHG emissions. In New York State, electricity generation is responsible for less than 20% of emissions while heating and transportation each produce between 35% and 40% of emissions. Thus, in New York, emissions from electricity are a third-level priority. In New York, a focus on adoption of heat pumps and electric vehicles will contribute more to cleaning our air and water than a focus on electricity.
It is important that this report identify strategies and technologies which are appropriate for the various regions of the country.

Heat and work have signs (positive or negative), and the sign of each depends on whether the system we are considering is gaining or losing energy. In this class, if a process makes the system gain energy, qqq and/or www are positive; if the process makes the system lose energy, qqq and/or www are negative. We can put this information into four formal statements: If heat flows into a system, qqq is positive. If heat flows out of a system, qqq is negative If the surroundings do work on the system, www is positive. If the system does work, www is negative.

heat trace (heating cable)
Heat trace or heating cable is used to warm or heat underground structures, storage tanks, vessels, and instrumentation in order to maintain a specified temperature or eliminate the possibility of freezing. Heat trace or heating cable accomplish this task by adding the amount of heat energy to the process fluid that is lost from the process fluid. It is desirable to maintain a certain temperature since higher temperatures reduce viscosity, enhance combustion, and prevent freezing or crystallization of the fluid. Within the oil and gas industry, elevated temperatures are required to separate the crude oil or raw natural gas to the surface and freeze protection is required to allow refining and distribution of the fluid (Thermon South Africa (Pty.) Ltd. ). Heat trace or heating cable often utilizes resistance wire to provide a medium for voltage to pass through. Due to the resistance of the wire, the heat trace or heating cable becomes warmer and is able to use this heat to warm the underground structures that it surrounds. One material used in resistance wires is nickel-chromium (Peterjohn, Melillo, Bowles, & Steudler, 1993). Heat trace has been used since the early 1900s to ensure the proper flow of petroleum, tar, and wax through pipelines. Since then, certain products within the petroleum and chemical industries needed to be kept between specific temperatures to ensure their quality. Today, the most commonly used heat trace medium is steam (Thermon South Africa (Pty.) Ltd. ).

frost heave
Before the understanding of frost heave, there was a widely held belief that rocks and stones could grow and multiply. Stones were believe to grow from small pebbles. These stones then rose to the surface of the ground. Another belief was that stones were the offspring of “mother-stones” or “breeding-stones.” Today, it is known that this motion of stones moving upwards toward the surface of the ground is due to frost heave. Frost heave occurs when water in soil or rock freezes and thaws in a cyclic process. This causes an upward movement of the surface of the ground due to the freezing of water underneath. Geologist Stephen Taber from the University of South Carolina proved through extensive research that “it was not expansion, but rather the formation of ice lenses by segregation of water from the soil as the ground freezes that is the principal cause of frost heave.” He also showed that liquids other than water can also cause frost heave. The direction of heave is governed by the growth of ice lenses. Ice lenses form perpendicular to the direction of heat flow, so it is not always the case that frost heave occurs in the path of least resistance (Manz, 2011).

ITM is based on the theory of temperament. Temperament is a quality resulting from the interaction of opposite properties present in elements consisting of minute particles. Thus, a uniform quality occurs which is present in all of them. Hotness, coldness, moistness, and dryness are four temperaments that naturally occur in every existingsubstance including living creatures (2)
These temperments match up with the four-fold alchemical division that uses the same four qualities of heat, cold, moisture and dryness.
