SHINIGAMI: tenhleten denialismus mě nepřestává fascinovat. Solární byznys roste čtvrtý desetiletí dvojcifernejma číslama ročně, každou pětiletku zdvojnásobí svý kapacity, ale ne, budeme se dohadovat, jestli se to opravdu stalo. To je zhruba tak dlouho, jako je věk průměrnýho nyxáka, ergo to není žádná šokující skrytá věc, ale fakt, kterej tě provází celej život.

Je to jako pozorovat lidi, co tvrděj, že kompy byly nejrychlejší v době pentií v pětadevadesátým a od tý doby to jde jenom z kopce. Zajímalo by mě, co tím sledujete, nejsi první, u koho to vidím, to doufáte, že když budete dostatečně silně řvát, že to tak není, tak se statistiky přepíšou na horší čísla?

K tej ucinnosti, 15.5. vacsinu dna prsalo ale aj tak mi solar pokryl 75% spotreby

Swanson's law is the observation that the price of solar photovoltaic modules tends to drop 20 percent for every doubling of cumulative shipped volume. At present rates, costs go down 75% about every 10 years.[1] It is named after Richard Swanson, the founder of SunPower Corporation, a solar panel manufacturer.[2]

SHINIGAMI: Tak ja myslim, ze v tom ohledu je spis dulezitej vyvon ceny nez vyvoj ucinnosti (ktera je shora uz dost blizko jasne ohranicena). A tam jsou ty cisla o dost optimistictejsi.

this slide basically sums up the thesis of Soil4Climate in a single composite image.

During the coevolution of grasslands and ungulates during the last 30 million years, approximately 2 trillion (yes, trillion) tons of carbon were sequestered out of the atmospheric (lowering concentrations from 1300 to under 300 parts per million). A significant part of this went into a new type of soil, called mollisols, which is the soil associated with grasslands, ruminants and "C4" grasses (maize, sugar cane, millet, sorghum, bluestem). This is why there is approximately 2 trillion tons of carbon in the soils of the world today. Without the coevolution of ruminants and C4 grasses, the current climate regime that made human evolution possible in the first place would not have come into existence. To get back to a safe climate (approximately 280 ppm CO2), 260 billion tons of carbon will need to be sequestered back into soil. Of course, restoring that soil also improves small water cycles which provides regional cooling in addition to other ecological enhancements. All this is possible, but only through restoration of degraded grasslands with proper grazing, and, in concert with restoration of forests and wetlands.

Sucho môže byť oveľa vážnejšie a kritickejšie ako korona. Už toto leto možu byť u nás teploty nad 40 stupňov.
Nový koronavírus odhaľuje našu zraniteľnosť. Zároveň je to však príležitosť lepšie pochopiť a brať vážnejšie aj niektoré ďalšie súvislosti našej zraniteľnosti, najmä s klimatickými zmenami. Jozef Pecho tvrdí že koronavírus je kríza, ktorá možno o pár mesiacov či o rok odznie, no klimatická zmena tu bude stále. „Má tendenciu amplifikovať, to znamená zhoršovať všetky následné krátkodobé krízy. Všetky ďalšie koronakrízy, alebo iné finančné, ekonomické, akékoľvek ďalšie krízy, ktoré prídu do nových fyzikálnych podmienok budúcej klímy, budú mať pravdepodobne horšie a citlivejšie dopady,“ myslí si klimatológ.

The exhibition »Critical Zones – Observatories for Earthly Politics« is about the critical situation of the Earth as it falls through the Coronavirus into a critical time. A new Earth policy also requires a new exhibition policy: We are broadcasting!
The growing exhibition at the ZKM will be combined with a digital exhibition that will also be rising steadily. The museum will become a »home museum« with a virtual accompanying program.
On May 22, 2020 from 6 pm, the exhibition will open with a streaming festival lasting several days, which will span the weekend of May 22–24, 2020. The program will consist of streamed guided tours through the virtual space as well as through the real, but not public exhibition, and will include interviews and lectures.
We are very much looking forward to meeting you in virtual space on all channels when we open our exhibition together and celebrate, think, speak and listen jointly for a whole weekend, until 24.05.2020.
We cordially invite you to the virtual exhibition opening on May 22, 2020 at 6 pm!
