NJAL: When experts in the fields covered by Lomborg check his texts, they most often find that the evidence has been distorted. Danish biologist Kåre Fog has systematically over many years checked Lomborg´s texts against his sources and references and against other scientific literature. His conclusion is that Lomborg´s texts are systematically manipulated to fit a certain agenda.
The web site Lomborg-errors has been established to document this claim. It gathers and publishes errors found in Bjørn Lomborg´s books, especially "The Skeptical Environmentalist" (2001) and Cool it! (2007).

In 1859, Tyndall showed that gases including carbon dioxide and water vapour can absorb heat. His heat source was not the Sun, but radiation from a copper cube containing boiling water. In modern terms, this was infrared radiation – just like that emanating from the Earth’s surface.
Previous work had shown that the Earth’s temperature was higher than expected, which was put down to the atmosphere acting as an insulator. But no-one knew the explanation for what we now call the greenhouse effect – gases in the atmosphere trapping heat.
What Tyndall did was to discover and explain this mechanism. He wrote: “Thus the atmosphere admits of the entrance of the solar heat; but checks its exit, and the result is a tendency to accumulate heat at the surface of the planet.”
He realised that any change in the amount of water vapour or carbon dioxide in the atmosphere could change the climate. His work therefore set a foundation for our understanding of climate change and meteorology.
Tyndall was not, however, the first to make the climate link. That prize goes to the American Eunice Foote, who showed in 1856 using sunlight that carbon dioxide could absorb heat. She suggested that an increase in carbon dioxide would result in a warmer planet.

aneb "worst case scenario is still our bestchoice"

But a new study published Monday in the Proceedings of the National Academy of Sciences argues that the high-end projection for greenhouse gas concentrations is still the most realistic for planning purposes through at least 2050, because it comes closest to capturing the effects "of both historical emissions and anticipated outcomes of current global climate policies, tracking within 1 percent of actual emissions."
The scenarios, called Representative Concentration Pathways (RCPs), roughly show how much warmer the world will be by 2100, depending on how much more fossil fuel is burned, and how the climate responds. The best-case scenario (RCP 2.6) is the basis for the Paris climate agreement and would lead to warming of about 3.2 degrees Fahrenheit (1.8 Celsius) by 2100. In that scenario, about 10 percent of the world's coral reefs could survive, and 20 percent of Alpine glaciers would remain.
The worst-case pathway (RCP 8.5) would result in warming of more than 8 degrees Fahrenheit (4.3 Celsius) by 2100, probably killing nearly all the world's reefs and definitely pushing vast areas of polar ice sheets to melt, raising sea level by as much as 3 feet by 2100.

Research: Crop plants are taking up microplastics
https://phys.org/news/2020-07-crop-microplastics.html

(CAS) recently found that microplastics are indeed contaminating edible plants, including vegetables we eat. The study was published in Nature Sustainability on July 13.

...

Despite the prevalence of MPs throughout the environment, the matter of MP uptake by crop plants has not received much attention.

For decades, scientists believed that plastic particles were simply too large to pass through the physical barriers of intact plant tissue. But this new study disproves this assumption.

"Cracks at the emerging sites of new lateral roots of lettuce and wheat crops can take in MPs from the surrounding soil and water. Those MPs can then be transferred from the roots up to the edible parts of the crop," said Prof. Luo.

...

at the lateral root emergence sites there are small cracks, and then the particles go through those cracks and enter the xylem vessels. Thus it is even possible that particles larger than the ones we studied might also be taken up by plants," said Dr. Li Lianzhen, first author of the study.

...

If MPs are getting into our crop plants, they are also getting into our meat and dairy. This raises obvious concerns about growing crops on fields contaminated with wastewater treatment discharge or sewage sludge, a process that could introduce MPs into the food chain. It also raises the key question of how MPs affect human health, a question for which there is as yet no clear answer.

SHEFIK: úspora emisí je zde, u nás nějakých 63% při současném energetickém mixu. https://fdrive.cz/clanky/dalsi-studie-potvrzuje-ze-elektromobily-jsou-vyrazne-cistsi-5315
Jinak hodně emisí na akumulátor bude i protěžba lithia a ta by se měla postupně snižovat recyklaci akumulátorů, plus další emise budem šetřit změnou energetického mixu, ale v tom nejsem úplně optimista když vidím co tlačí vláda a průmysl.
Konec fosilních paliv v Čechách je možná dál než to vypadá.

LINKOS: souhlasim, mluvis o efektivite vyuziti energie a tam je to jasny, ohledne provozu tam sou ale i dalsi duvody, napr. ze elektricky auto ma od dva rady mene fyzickych dilu - tedy vse okolo, jako poruchovost, transport (vcetne transportu auta do servisu), vyroba dilu v ruznych lokalitach a jejich doprava....

u vyroby EV je to az o 60% vyssi produkce CO2, a to hlavne kvuli baterce. takze jak rikas, cim dyl EV (baterie) vydrzi jezdit, tim lip pro klima.

tady ale hrajou obrovskou roli technologie a jejich vyvoj. EV je ted hype a bude trvat nejakej cas, nez ty technologie zmaturuji a standardizuji se/zefektivni se masova vyroba. uz za 5 let bude EV uplne jiny. uz ted Tesla odstranuje "nejspinavejsi" cobalt z baterii a dosahla million mile zivotaschopnosti..

konec fosilnich paliv uz je za rohem :) a kdyz nekdo presedla na kolo, tim lip, usetri se jeste na silnicich

SHEFIK: nj, ale i to elekteoauto dobíjené uhlím má stále nižší provozní uhlikovou stopu, protože 2/3 energie v motoru nevyplitvas na topení. Jinak oze tomu samozřejmě dávají jiný rozměr. Problém ale je náročnost na výrobu, ta je o něco vyšší než u klasického spalováku, ale ne zas o tolik. Tady pak narážíme na to jak dlouho člověk auto provozuje, protože pokud budeš každý 3,4 roky kupovat nové tak tam je zase problém s náročnosti výroby u všech.
Na druhou stranu u nás je v průměru 14 lety vozový park, takže i kdyby se elektromobily rozmohli, bude trvat dalších cca 14 let než nám je naprodavaji Němci jako ojetiny.
V tomhle ohledu by měli mnohem větší význam elektokola, které se teď stávají populární na dojíždění do práce.

SHEFIK: at neplacam slamu :) byl to seaweed..

https://www.agric.wa.gov.au/...carbon-farming-reducing-methane-emissions-cattle-using-feed-additives

In Australia, direct livestock emissions account for about 70% of greenhouse gas emissions by the agricultural sector and 11% of total national greenhouse gas emissions. This makes Australia’s livestock the third largest source of greenhouse gas emissions after the energy and transport sectors. Livestock are the dominant source of methane (CH4) and nitrous oxide (N2O), accounting for 56% and 73%, respectively, of Australia’s emissions.

...

Feeding one type of seaweed at 3% of the diet has resulted in up to 80% reduction in methane emissions from cattle.

YMLADRIS: jeste jsem to necet, ale pripomina mi to diskuzi s elektroautama - kdyz mas elektrinu z uhli, jak na vyrobu, tak provoz elektroauta, tak je jeho ekologictnost oproti dieselu diskutabilni. jakmile mas input cistsi (renewable/solar atd.), jses az na 30% emisi... vzdy jde o pouzitou techninku (metodicky postup) nebo technologii...

vic bych ale u dobytka koukal na metan - jenze ale i tam bude tam vic faktoru, nedavno sem nekde cetl ze nejaky specialni traviny u hoveziho redukujou tvorbu metanu v zazivacim ustroji o desitky procent. asi je nebudeme sejt na vsech pastvach po svete, ale je to dobrej highlight na zamysleni, ze lide se casto zameruji na konec problemu (dobytek/jist maso), ne na problem samotny (pricina tvorby metanu/co2)

Jenže co když budete krávy pást na již dávno zřízené pastvině někde v podhůří moravských hor a nemuseli jste kvůli tomu klučit jihoamerický prales? Doberete se toho, že kilo hovězího masa váží rázem „jen“ 6 kilogramů emisního CO2. Což je oproti původní stovce dost zásadní rozdíl.

New Study Confirms Extensive Gas Leaks in the North Sea −
https://evobsession.com/new-study-confirms-extensive-gas-leaks-in-the-north-sea/amp/

We have combined investigations at additional wells with extensive seismic data. The results clearly show that thousands of tons of methane are leaking from old drill holes on the North Sea floor every year,’ says Dr. Christoph Böttner, who is the main author of the study, which is part of his doctoral thesis at GEOMAR.

...

The positions of the boreholes and the location and extent of the gas pockets indicate that this area of the North Sea alone has the potential to emit 900 to 3700 tonnes of methane every year

...

In seawater, methane is usually consumed by microbes. This can lead to local seawater acidification. In the North Sea, about half of the boreholes are at such shallow water depths that part of the emitted methane can escape into the atmosphere. Methane is the second most important greenhouse gas after carbon dioxide.
