The Practical Impossibility Of Large-Scale Carbon Capture And Storage

Further to the recent Talkshop article, confirmation that carbon capture is little more than a silly game using lots of energy and incurring vast costs for minimal or even net-negative of its hoped-for results.

The Environmental Protection Agency is working on a new rule that would set stringent limits on carbon dioxide (CO2) emissions from US power plants. Utilities would be required to retrofit existing plants with carbon capture and storage (CCS) technology or to switch to hydrogen fuel. Others call for the use of CCS to decarbonize heavy industry. But the cost of capture and the amount of CO2 that proponents say needs to be captured crush any ideas about feasibility.

Carbon capture and storage is the process of capturing carbon dioxide from an industrial plant before it enters the atmosphere, transporting it, and storing it for centuries to millennia. Capture may be accomplished by filtering it from combustion exhaust streams. Pipelines are proposed to transport the captured CO2. Underground reservoirs could be used for storage. For the last two decades, advocates have proposed…

New Study: Climate Models Have Uncertainties, Errors Over 100x Larger Than Claimed Drivers Of Warming

Per a new study on the hydrological cycle’s role in climate change, today’s state-of-the-art climate models “assume the mean relative humidity at the ocean surface is constant.” They are also known to “assume unchanged wind conditions.” Even with this imaginary constancy, “uncertainties in modeling the hydrological cycle significantly [orders of magnitude, or more than 100-fold] exceed the observed effects of global warming.”

In a summarizing analysis of the thermodynamics associated with Earth’s hydrological processes (Koutsoyiannis, 2021), we learn that the impact of the natural heat exchange by evaporation, or the latent heat transfer from the ocean to the atmosphere is approximately 80 W/m²/year, or 1,290 ZJ/year.

Total climate impacts from human greenhouse gas emissions amount to only  0.038 W/m²/year (0.612 ZJ/year in 2014).

Thus, Earth’s “natural locomotive” is about 2,100 times larger than claimed for anthropogenic forcing.

It is therefore clearly evident that “water is the main element that drives climate, rather than just being affected by climate as commonly thought.”

Quote selections from a new review paper (Feistel and Hellmuth, 2023) on the thermodynamics of air-sea processes (i.e., evaporation) expand on the extreme nature of this magnitude differential in even more detail.

Effectively, the dominance of water in driving climatic processes is so massive that claims we can detect a 0.038 W/m²/year anthropogenic forcing signal amid the orders of magnitude larger background of internal or natural variability, uncertainty, and calculative error is, in a word, absurd.

“[T]he climate of the Earth is ultimately determined by the temperatures of the oceans,” as “the oceans have a heat capacity about 1000 times greater than the atmosphere and land surface.” Because this orders-of-magnitude oceanic dominance, even “a minor heating flux of just 0.005 W/m² is sufficient to raise the atmospheric temperature at an observed rate of 2 °C per century.”

“[A]n error of 1% in RH [relative humidity] … would cause an error of 5 W/m² in the computed ocean atmosphere latent heat fluxes. For comparison, the observed global warming of the atmosphere is driven by a minor climatic forcing of only 0.005 W/m², the total anthropogenic power consumption amounts to 0.02 W/m², and the ocean is warming up by 0.5 W/m².”

“[N]umerical climate models possess uncertainties that exceed certain relevant, either observed or predicted, effects of global warming by orders of magnitude.”

“[T]he global mean of LHF [latent heat flux] was found to be overestimated in the MME [multi-model ensemble] by 5.9 W/m²…”

“Observations and models of oceanic evaporation typically deviate from one another by 6 W/m², or 6%.”

“If also expressed per global surface unit area, even an increase in the large oceanic heat content by as much as 0.5 W/m² would remain well below the model uncertainty range.”

The Case of the Missing Climate Crisis: Greek Edition

News Brief by Kip Hansen  — 4 May 2023

A sharp-eyed reader suggested covering this new paper with the clever title:  “In Search of Climate Crisis in Greece Using Hydrological Data: 404 Not Found”, published 27 April 2023 in the hydrology journal Water.  [ .pdf copy available at that link ].

The paper, by Demetris Koutsoyiannis and seven others, all associated with the Department of Water Resources and Environmental Engineering, School of Civil Engineering, National Technical University of Athens and/or the Department of Agriculture, University of Patras, is in response to the EU’s declaration of a Climate Emergency:  “Given the European declaration of climate emergency, along with the establishment of a ministry of climate crisis in Greece, this dataset was also investigated from a climatic perspective using the longest of the data records to assess whether or not they support the climate crisis doctrine.

You can guess by the title of the paper that, in regards to drought, the “Climate Crisis” was not found in Greece – your computer would have reported “Error 404:  Climate Crisis Not Found”.

Using the longest hydrology records available, the authors found:

“The two over-century-long rainfall time series of Greece (Athens and Thessaloniki) show that the record average and maximum rainfall depths occurred in the 19th or early 20th century. Compared to other locations on the globe with long time series, these two time series of Greece show much smaller to negligible climate variability, both in mean and maximum rainfall heights.”

“In terms of the annual average rainfall, the two most important climatic events that have occurred in Greece from the middle of the 20th century to the present day are (a) the grouping of the high records of the annual average rainfall depth, namely 1/3 of all stations, in one year, the hydrological year 1962–63, and (b) the intense and persistent drought before and after 1990, where the five-year period from 1988–89 to 1992–93 saw more than 50% of all record lows.”

Greece has seen this alternation of dry periods and wetter periods over the entire historical period, yet civilization flourished there over the same period:

“The alternation of dry and wet periods is also a notable characteristic revealed by the study of hydrological data. This behaviour has been known to Greek philosophers since the 6th century BC (cf. Xenophanes;). Besides, the dry conditions in Greece have not been an obstacle to the development of Greek civilization but rather a trigger for the development of science, technology, and management. The ancient aqueducts of Athens that are still operational to date are a living testimony of this fact.

“A modern repetition of the latter achievement is that, as a result of the successful management of the big drought 30 years ago, Athens now has a perfect water supply system. The successful handling of this crisis is arguably one of the greatest achievements of modern Greek public policy. It would have been impossible without competent and pragmatic leadership and public participation.”

The realities of climate, the shifting from dry to wet and back to dry periods, was the impetus for advancements in science and engineering and social policy, successfully overcoming the challenges presented by the real world.

There have been dry periods, some deep and spanning years and there have been wet periods.  This describes the Mediterranean climate type – the same climate classification as found in California and much of the Pacific Coast of the United States.   But Greece’s 2,000+ years of experience, wisely acted upon, have saved Greece from the downsides of the dry periods and allowed them to take advantage of the wetter times, establishing the infrastructure and policies that truly benefit the people and ensure a constant and adequate water source for the cities of Greece.   

Bottom Line:  Error 404: Not Found

Sorry European Union,  a thorough search of long-term hydrological data found no Climate Crisis-caused drought in Greece.

Kudos are due the authors of this study – fighting back against the tide of climate nonsense.

Author’s Comment:

[Try as I might, I could not recover the name of the helpful reader that suggested this paper as the subject of a post here. If it was you — please let me know in comments. ]

One of the many curses of modern society, found very often in the Sciences, is Presentism – the partiality to the present (conditions, attitudes, values) as opposed to taking a longer-term viewpoint.  Thus often in Climate Studies, we find the present (or very near past —  ‘when I was a kid’ ) being held up as the ideal. 

We find this in California’s battle with its own historical climate – dry periods followed by deluges of rain.  (See the Great Flood of 1862). 

But the prophets of doom, the prophets of crisis, must fail as they spread falsehoods based on perverse ideologies. 

Thanks for reading.
