    Is this sustainable? | Consciousness of Sheep
    https://consciousnessofsheep.co.uk/2020/04/15/is-this-sustainable/

    For the moment and temporarily, governments can prop up the economy in this way because the overwhelming majority of the population still buy into the belief that we will return to some form of “normality” and that the economy of the future will be bigger and wealthier than the economy as it was before the pandemic struck; allowing the debt to be repaid. One vision of that bigger and wealthier economy involves the massive deployment of non-renewable renewable energy-harvesting technologies, switching from internal combustion engines to electric motors and swapping physical products (books, DVDs, face to face meetings, etc.) with digital equivalents (e-books, mp4, Zoom, etc.). But these fantasies depend upon a planetary resource base that simply isn’t there anymore.

    Several key minerals are only available today because we haven’t attempted a WWII-scale Green New Deal. As Tad Patzek explains:

    “To compare the WWII industrial effort with the global dislocation necessary to ameliorate some of the effects of climate change is surprisingly naïve… This comparison also neglects to account for the human population that has almost quadrupled between the 1940s and now, and the resource consumption that has increased almost 10-fold. The world today cannot grow its industrial production the way we did during WWII. There is simply not enough of the planet Earth left to be devoured.”

    Less obviously, the energy that we depend upon to do anything is itself increasingly constrained as most of the large oil fields around the planet pass peak production. It is not that there isn’t plenty of oil – or, indeed, fossil fuels in general – under the ground. Nor that enhanced recovery techniques, deep water drilling, hydraulic fracturing and strip-mining bitumen sands cannot continue to deliver vast quantities. Rather, the problem is that each additional barrel of oil from this point on is taking more energy to produce, so that the net energy available to the wider economy is shrinking,

    The net energy or energy return on energy invested can fall from 50:1 to as low as 15:1 without having a major impact on the wider economy. Between 15:1 and 5:1 things become extremely difficult. And beyond 5:1 any semblance of a modern economy is impossible. Which raises the question, where are we now? To which, sadly, there is no definitive answer. Conventional oil is probably still above 20:1. Hydraulically fractured shale oil is somewhere around 5:1. Bitumen sands are around 2.5:1 and corn-based biodiesel is energy-negative (it takes more to produce than it provides in return). Solar farms are around 5:1 and windfarms between 15:1 and 20:1 – but remember these technologies are not renewable; without a steady supply of energy-cheap fossil fuels (and in the absence of an energy-dense alternative) these technologies are likely to go the same way as the wider economy.

    ...

    The term which best describes what happens from here on is ‘de-growth’. This is a concept that some have advocated as a positive choice, but it is, in fact, being forced upon us by a relentless deterioration in the energy-driven equation which determines prosperity.”

    The current lockdown measures are only “sustainable” for as long as national currencies maintain their value. National currencies, in turn, are only sustainable for as long as the myth of a bigger and wealthier future can be sustained. That myth depends upon growth in the net energy available to the economy that ceased sometime around 2005. There is already a growing list of things that we used to be able to do that – for net energy reasons – are no longer possible; from the collapse of commercial supersonic flight at one end to the growth of such things as bicycle delivery services and hand car washes at the other. In the aftermath of the pandemic, we will likely say goodbye to many more things that we used to take for granted until such time as investors notice and either markets and asset prices collapse for good or stagflation arrives to remove the paper wealth that western economies currently run on.

    There is nothing sustainable about the current lockdown. But, then again, there was nothing sustainable about the “normal” economy we were operating anyway. The future is not green growth but de-growth; not more and better, but make do and mend.

    As America fought coronavirus, Trump’s Interior Department rushed through dozens of environmental attacks
    https://medium.com/...rus-the-interior-secretary-rushed-through-dozens-of-environmental-1fa91abe02c7

    A new analysis by the Center for Western Priorities finds that in the month after President Trump signed the first emergency coronavirus bill, the Interior Department took dozens of policy actions unrelated to COVID-19, moving ahead with unfettered oil and gas leasing, removing protections for endangered wildlife, and expanding mining operations across the country.
    CWP’s analysis identified 57 separate actions taken by Interior Department agencies since March 6, when President Trump signed the first coronavirus emergency bill. Those 57 actions include 34 public comment periods that were opened or closed by the Interior Department despite numerous requests from local elected officials and members of Congress that Interior Secretary David Bernhardt suspend rulemakings during the pandemic.

    Evropou zní volání po rychlejší zelené transformaci. ČR opět stojí stranou
    https://denikreferendum.cz/...opou-zni-volani-po-rychlejsi-zelene-transformaci-cr-opet-stoji-stranou

    Součástí prohlášení je také snaha o rychlejší přijetí ambicióznějšího cíle snižování emisí do roku 2030, ze současných čtyřiceti procent na alespoň padesát, optimálně pětapadesát procent. Dále v ní státy požadují navýšení investic do zelené mobility, rekonstrukce budov, vývoje obnovitelných zdrojů, cirkulární ekonomiky a obnovy divočiny.

    „Měli bychom se vyvarovat pokušení zavádět krátkodobá řešení současné krize, která zapříčiní, že naše ekonomiky budou dlouhodobě závislé na fosilních palivech. Musíme společně a solidárně propojit boj proti nemoci Covid-19, klimatické krizi i ztrátě divočiny,“ uvádí se v prohlášení.

    Výzvu v minulém týdnu zveřejnilo deset států, včetně Itálie a Španělska nejvíce zasažených koronavirem. Kromě nich se přidalo Dánsko, Rakousko, Finsko, Lotyšsko, Lucembursko, Nizozemsko, Portugalsko a Švédsko. O velikonočních prázdninách se postupně přidala Francie, Německo a Řecko. O dalším společném postupu a opatřeních na obnovu ekonomiky budou lídři států Evropské unie jednat 23. dubna na videosummitu

    Global depletion of soil organic carbon stock by historic land use and soil degradation is estimated at 133 Pg C. Estimated to 2-m depth, C stock is 2047 Pg for soil organic carbon and 1558 Pg for soil inorganic carbon, with a total of 3605 Pg. Thus, even a small change in soil organic carbon stock can have a strong impact on atmospheric CO2 concentration. Soil C sink capacity, between 2020 and 2100, with the global adoption of best management practice which creates a positive soil/ecosystem C budget, is estimated at 178 Pg C for soil, 155 Pg C for biomass, and 333 Pg C for the terrestrial biosphere with a total CO2 drawdown potential of 157 ppm. Important among techniques of soil organic C sequestration are adoption of a system-based conservation agriculture, agroforestry, biochar, and integration of crops with trees and livestock. There is growing interest among policymakers and the private sector regarding the importance of soil C sequestration for adaptation and mitigation of climate change, harnessing of numerous co-benefits, and strengthening of ecosystem services.

    “Nepal is ground zero for the impacts of climate change. As a country with one of the most fragile ecosystems — the Himalayas — and an economy that is heavily reliant on favorable climate conditions, Nepal is probably one of the most exposed.”
    Pushed out of their village by a drought and lack of food, a group of Nepalis are fighting to amplify the voices of those forced to relocate by the planet’s warming.

    TUHO: Metan

    “Here we are. It’s 2020, and it’s not only not dropping. It’s not level. In fact, it’s one of the fastest growth rates we’ve seen in the last 20 years,” Drew Shindell, a climate scientist at Duke University, told Scientific American.

    Global methane levels have hit an all-time high after what appears to be a near-record yearly atmospheric increase in the potent greenhouse gas.
    The concentration of methane in the Earth’s atmosphere reached nearly 1,875 parts per billion in 2019, up from the previous year’s 1,866 parts per billion, according to preliminary data collected by the National Oceanic and Atmospheric Administration (NOAA).

    Europe’s green energy companies are emerging as shelter for investors in market fallout from the coronavirus.
    Utilities in the region are holding up better than other industries in the health crisis. While the Stoxx 600 Index of European shares fell 21% since the start of the year, the utilities component of that measure has declined only 14%. Within that, renewable power producers are outperforming their less green rivals.
