    Rupert Read: Some thoughts on the Davosification of #COP2

    "The problem is the economic system which commands companies to keep expanding and ‘externalising’ costs just to stay in business. This problem cannot be sorted by voluntary alliances alone; because built into it is a deep free-6rider problem. So long as businesses are not held to a higher playing field by regulation, there will always be openings for bad climate actors to exploit"

    TUHO: The analysis becomes very interesting when the researchers leave freight behind and start thinking about what could be done with many big, mobile batteries. Even without moving them, freight companies could use their capacity to provide grid stabilization services or sell back power when the price gets high. In extreme cases, this system could actually pay for the entire infrastructure.

    "Preliminary estimates of the most expensive 90 hours per year in the ERCOT [Texas] market, for example, show that batteries could be discharged at $200/kWh, potentially generating enough revenue to pay for the upfront battery cost in a single year," the study says.

    The batteries could also be moved to locations that have been struck by power outages or natural disasters, towed there by locomotives running on diesel instead of draining the batteries.

    All of this would add considerable levels of complexity to the task of supplying freight companies with the energy needed to do their primary job of moving material around. Getting the most out of the batteries might involve constantly running the numbers on electricity and diesel prices and comparing the result to charging capacity and shipping deadlines. But if done right, the idea has the potential to bring zero emissions to an otherwise difficult-to-decarbonize form of transportation.

    In the US, the typical freight car travels an average of 241 kilometers per day when in operation. So the researchers created a battery big enough to move that distance as part of a large freight train (four locomotives, 100 freight cars, and about 7,000 tonnes of payload). They found that lithium ferrous phosphate would let each of the four locomotives be serviced by a single freight car configured as a giant battery. The battery would only occupy 40 percent of the volume of a typical boxcar and would be seven tonnes below the weight limit imposed by existing bridges.

    Because of the efficiency of direct electric power, the train would use only half the energy consumed by an internal combustion engine driving an on-board generator. And while an above-average trip wouldn't work on a single charge, freight trains normally stop several times a day to change crew and refuel, providing an opportunity to boost the range with some fast charging. And if longer breaks are possible, the battery cars themselves could be swapped out.

    While the system wouldn't require new locomotives, the batteries and charging infrastructure it would need make for some substantial up-front costs. The researchers added up all these costs and then calculated the price of electricity that would be needed to make the whole thing price-competitive with diesel.

    Regenerative Agriculture: A Way To Sequester Carbon - CleanTechnica
    https://cleantechnica.com/2021/11/12/regenerative-agriculture-a-way-to-sequester-carbon/

    On November 7, 2021, food systems experts gathered at the UN Climate Change Conference (COP26) in Glasgow to discuss using investment and true cost accounting (TCA) as levers for food systems change. Those discussions were the offspring of an earlier UN Food Systems Summit white paper that discussed how one of the central problems of current food systems is that many of the costs of harmful foods are externalized — they’re not reflected in actual daily market prices

(plochy matou, ve sloupečcích by poměr vypadal reálněji) Tedy aby na tom CZE byla stejně na hlavu jak USA tak by USA muselo mít 400 milionů obyvatel, ale má jen 336. Takže je USA na hlavu o dost hroší v emisích jak my. (plošné grafy jsou podle mě UMYSLNĚ zavádějící)

    Humans are guilty of breaking an oceanic law of nature: study
    https://phys.org/news/2021-11-humans-guilty-oceanic-law-nature.html

    A new international study carried out by the Institute of Environmental Science and Technology of the Universitat Autònoma de Barcelona (ICTA-UAB) has examined the distribution of biomass across all life in the oceans, from bacteria to whales. Their quantification of human impact reveals a fundamental alteration to one of life's largest scale patterns.

    ...

    In contrast with an even biomass spectrum in the pre-1850 ocean, an investigation of the spectrum at present revealed human impacts on ocean biomass through a new lens. While fishing and whaling only account for less than 3 percent of human food consumption, their effect on the biomass spectrum is devastating: large fish and marine mammals such as dolphins have experienced a biomass loss of 2 Gt (60% reduction), with the largest whales suffering an unsettling almost 90% decimation. The authors estimate that these losses already outpace potential biomass losses even under extreme climate change scenarios.

    "Humans have impacted the ocean in a more dramatic fashion than merely capturing fish. It seems that we have broken the size spectrum—one of the largest power law distributions known in nature," reflects ICTA researcher and co-author Dr. Ryan Heneghan. These results provide a new quantitative perspective on the extent to which anthropogenic activities have altered life at the global scale.
