YMLADRIS: ne, nevytvorila. Obcas tu ale padaji takove nazory, ze degrowth, nebo zit tak jak sme zili v minulosti je to co civilizaci zachrani a jine modely civilizace nejsou existenceschopny, tak se mi do toho primichaly emoce. Co sem chtel rict je, ze Musk kouka dopredu a snazi se nektery z tech aktualnich painpointu/zmenit mitigovat

V te myslence jsme se asi nepochopili, co rikam je, ze pokud chceme soucasnou civilizaci zachovat s co nejmensimi ztratami na zivotech, neni cestou vypnout fosil, ale nastavit max prioritu na transformaci energetiky, popripade stavebnictvi a chemickyho prumyslu.

Neni to o tom, ze od zejtra nebudem jezdit na naftu. Ty solary, vetrniky atd. musime vybudovat co nejrychleji a mezitim musime zajistovat logistiku a bezpeci pro populaci zeme, tzn od stavby silnic, po prevoz potravin a materialu, prevozu nemocnych, vyroby leku, v tuhle chvili diky Rusku bohuzel i na military atd. Tohle neni ze dne na den, ani z roku na rok, nejde to proste jen tak 'vypnout' aniz by bylo cim to nahradit

...

Carbin tax se samozrejme hodi a emsini povolenky pomahaj dorovnavat ty 'realne' naklady na energie, ale samotne CC zarizeni jednak nejsou technologicky tak daleko, aby byly nakladove efektivni (dokud nebudou prebytky levne clean energie) a jednak tu carbon dan nikdy nezavede celej svet. Muze to byt nejaky doplnek v budoucnu/pro (energeticky) bohate zeme, ale tou optimalni cestou by melo byt snizit naklady na clean energii, protoze pak cely svet tyhle technologie prevezme bez nutnosti 'efektivni' diplomacie OSN, protestu ExtinctionRebellion, sebevrazd zemedelcu...

(Plus zustane samozrejme otazka co se soucasny carbon debt, tam muze CC hrat vetsi roli pri dostatecny skale a globalni vuli)

SHEFIK: asi jsem nejakym zpusobem vytvorila zdani, ze toto navrhuji?

--

jinak CC tuny co2 ted stoji 600$. nedovedu si to prevest na zvyseni ceny, tj o kolik vic by stalo vytapeni domu nebo doprava nebo prumysl nebo steak, pokud by automaticky muselo se montovat CC zarizeni. to jako rozvadim tvou myslenku o umreni hladem, jen tak

A není někde český (či sk .)) překlad toho IPCC reportu 22?

XCHAOS: a to "jde do prodeje" znamena, ze si to muzes zarezervovat, ah tak urcite :) porad je to ve vyvoji a na elektrovozitka je tu jiny klub, nemluve o cene :D

YMLADRIS: vratit o 1000 let zpet bylo mysleno, ze na transformaci potrebujeme fosil. Nejde najednou vystoupit zejtra rano z aut, shodit je ze skaly a tvarit se, ze je vsecko ruzovy a eko. Kdyby od zejtra jezdily jen elektromobily, 99% populace do mesice umre, z mnoha ruznych pricin, nejen hladem.

YMLADRIS: tak ono uridit Teslu a SpaceX, k tomu 5 deti a jeste resit dalsi topic (i kdyz souhlasim ze nemene dulezitej) muze bejt uz nad lidsky sily :)

Kazdopadne ne vsecko musi clovek delat sam. Nektery veci se daj outsourcovat. A myslim, ze Musk dela co muze, aby k vykonum dostatecne motivoval i ostatni

YMLADRIS: Musk se ale snazi 'setrit emise' jenze vi, ze to nedava smysl ted a tady, ze spolecnost nejde rozbit, zredukovat a vratit kulturne 1000 let zpatky. Tesla je jeho nejvetsim ekologickym projektem. (Teda az na ten jeho fanouskovskej bitcoin platby vystrelek)

S CATLem uzavrel smlouvu na bezkobaltovy baterie jako prvni. Pevne verim, ze bude Tesla bude jednou z prvnich co nahradi lithium jinym, hojnejsim, eco friendly prvkem do baterek, pokud budou konkurenceschopny tem lithiovejm.

Mj.soucasti Tesly, pod taktovkou jeho bratru je kontejnerovy/modulovatelny pestovani microgreens, napajeny solarem a druhou silnou vetvi jsou solarni strechy (solarni tasky+powerwall).

Powerwally se pak skalujou az na uroven zaloh elektraren, napr. v australii.

Plus 'decentralizace/stabilizace site' skrze virtualni energeticky uloziste (propojeny Tesla auta v siti).

Tenhle clovek dela pro transformaci nasich fosilnich energetickejch toku do nejakyho sustainable modelu jako malokdo jinej

If anyone wants my "take" on the latest IPCC report then here goes (will be writing something about this later, but to be honest, this thread will probably allow me to say what I want to say more effectively).

1.5°C is over. We now have to imagine the most fabulous scenarios to truly honour the Paris Agreement. That includes increasingly including large-scale removal of CO2 from the atmosphere to drag down temps after "overshooting".

We are still firmly on course for around 3°C by end of century. But really these end of century and even mid-century projections & targets are meaningless. What we need is the reduction of fossil fuel use NOW (sorry for shouting).

The reason we're not cutting fossil fuel use is not because it's really hard (it is) or represents huge challenges for finance (it does). It's because a tiny fraction of humanity is resisting with all of its considerable power. Power it has accrued with fossil fuels.

I appreciate "Fossil fuel fucks are stealing my children's future" isn't the sort of title IPCC will use in press releases or SPMs but that's the brutal reality. And I'm very frustrated about why we academics find it so hard to say that (or family friendly version).

We are still playing the game of producing increasingly absurb scenarios and then watching as civilisation carries on regardless. Now this doesn't mean we haven't made some huge progress in decarbonising. We are seeing energy transformations in many places.

But it's nowhere near enough and I guess that most academics either know that or suspect it. We have to turn off fossil fuels. Not overnight - that will kill billions. But VERY SOON. And that is a direct challenge to the most powerful organisations the world has ever seen.

Did you ever think they would wake up one day and decide to implode their industry? I'm not painting them as the victim here, but they will require support from governments to fundamentally repurpose their missions. This cannot be left to the market.

That's what this latest IPCC report says to me. I am profoundly grateful to all (lead)authors & reviewers. We would be in a far worse place without them. But now we need a new stage of academic engagement with the greatest challenge humanity has ever faced.

That's why I'm working with facultyforafuture.org Perhaps you would like to join us.

Gloom Reality: Even the Most Daring Technologies Can No Longer Reverse Impacts of Climate Change | Nature World News
https://www.natureworldnews.com/articles/49777/20220307/gloom-reality-even-daring-technologies-longer-reverse-impacts-climate-change.htm

"SRM carries a severe danger of changing regional and seasonal rainfall patterns and ozone depletion, ocean acidification, and other known and undiscovered negative consequences."

....

Outside of the IPCC, opposition to SRM is growing: over 240 eminent worldwide scientists have asked for a solar geoengineering non-use agreement that would essentially stop SRM from progressing.

A recent SRM equipment test over indigenous land in Kiruna, Sweden, was canceled amid vociferous objections from the Saami Council and environmental groups. They believe that climate modification is fundamentally incompatible with indigenous cosmology.

The only logical conclusion is that we must, by all means necessary, begin on pathways that prevent a 1.5°C overshoot and climatic collapse.

:Many professors signed, but I don’t get it.

(1) We oppose SRM as ungovernable & worry about a termination shock;

(2) BUT want 1.5°C, which requires SRM;

(3) BUT don’t focus on the ongoing termination shock from sulfate aerosol cuts?

Genuinely puzzled! Maybe someone can help?

Why Do We Cling to Art in Apocalyptic Times? – ARTnews.com

We face a choice, amid the slow collapse of a derelict civilization. It is not a choice of whether to stop global warming, whether to head off its inevitable consequences, or whether to save the world. The choice we face, like the choice Ernst faced on his escape from Camp des Milles, is simply whether to accept the reality we find ourselves in. Such an acceptance demands letting go of the burdens we have dragged so far, letting go of any hope for salvation, letting go of every piece of hoarded flotsam we think we might yet need, and facing the fact that the new world we are doomed to inhabit is as alien to our lives today as are the moons of Jupiter, the ziggurats of the Aztecs, or the blood cults of the ancient Greeks. There is only a narrow passage to this new world, the eye of the fiery needle, and to linger on the threshold is to die. On the doorway’s lintel are inscribed these words: “Abandon hope all ye who enter here.

We're Not Facing a Global Food Crisis | Aaron Smith
https://asmith.ucdavis.edu/news/russia-ukraine

In summary, the Russian invasion is a large shock for agricultural commodity markets, but not historically large. Markets and trade patterns will adjust to absorb it. Farmers around the world will produce more and consumers will cut back or substitute. The transition may be difficult in some places, especially countries such as Egypt that typically rely on wheat from Russia and Ukraine



Russia, Ukraine, and Food Supply: Look at the Prices | Aaron Smith
https://asmith.ucdavis.edu/news/russia-ukraine-redux

Numerous countries, notably those in the Middle East and North Africa (MENA), import a high percentage of their calories from Russia and Ukraine. For example, wheat contributes more than a third of calories consumed in Egypt, and half of this wheat comes from Russia and Ukraine. Lebanon imports about 90% of its wheat and gets most of its imports from Russia and Ukraine. These countries will need to find new suppliers this year.

The war will also disrupt food supplies to people in Ukraine and to refugees who have fled to neighboring countries.

These are serious issues and I don't intend to diminish their importance. Low-income consumers in these and other countries can be severely affected by relatively small increases in food commodity prices, especially given that wheat prices were already relatively high before the invasion. Wealthy governments and donors can help bridge the gap.

...

between the summer of 2020 and the end of 2021. They have not increased much since Russia invaded Ukraine.

A couple of weeks ago, I wrote: "If sanctions cut Russia and Belarus off from world markets, then it will leave a hole that other producers will need to fill. China produces almost all of the nitrogen and phosphate it uses, so it will not absorb Russia's exports. However, the apparent lack of a post-invasion price spike suggests traders are not yet worrying about a global shortage of fertilizer." This still holds true.

Moreover, wheat and corn traders know about fertilizer prices, and they factor that information into their trading decisions. If they were worried that the invasion would create fertilizer shortages and thereby seriously curtail food production, then they would bid wheat and corn prices up. But, they aren't doing that.
