Global team of scientists determine 'fingerprint' for how much heat, drought is too much for forests
https://phys.org/news/2022-04-global-team-scientists-fingerprint-drought.html

Just published in the journal Nature Communications, the study compiles the first global database of precisely georeferenced forest die-off events, at 675 locations dating back to 1970. The study, which encompasses all forested continents, then compares that information to existing climate data to determine the heat and drought climatic conditions that caused these documented tree mortality episodes.

"In this study, we're letting the Earth's forests do the talking," said William Hammond, a University of Florida plant ecophysiologist who led the study. "We collected data from previous studies documenting where and when trees died, and then analyzed what the climate was during mortality events, compared to long-term conditions."

After performing the climate analysis on the observed forest mortality data, Hammond noted, a pattern emerged.

"What we found was that at the global scale, there was this consistently hotter, drier pattern—what we call a 'hotter-drought fingerprint' – that can show us how unusually hot or dry it has to get for forests to be at risk of death," said Hammond, an assistant professor in the UF/IFAS agronomy department.

The fingerprint, he says, shows that forest mortality events consistently occurred when the typically hottest and driest months of the year got even warmer and drier.

"Our hotter-drought fingerprint revealed that global forest mortality is linked to intensified climate extremes," Hammond said. "Using climate model data, we estimated how frequent these previously lethal climate conditions would become under further warming, compared to pre-industrial era climate—22% more frequent at plus 2 degrees Celsius (plus 3.6 degrees Fahrenheit), to 140% more frequently at plus 4 degrees Celsius (plus 7.2 degrees Fahrenheit

TADEAS: no a co, das recenzi na knizku?
jinak teda ten celej koncept vzniknul castecne i na zaklade debat s tebou, tady a elsewhere a koukam, ze jsem te nenapsal do podekovani, tak sorry.

YMLADRIS: to sem netusil, pac u nas doma se to moc nedeje, ale je fakt ze s detma je to vetai challenge a mame hladovyho psa...

myslel sem ze trzne se to nejak utilizuje (napr. zbytky z restauraci pro prasata), ale u jedincu/entit co plejtvaj s tim asi tezko neco delat...

Dokonce je to globalne 30%

Food Waste
https://ec.europa.eu/food/safety/food-waste_en

In the EU, around 88 million tonnes of food waste are generated annually with associated costs estimated at 143 billion euros (FUSIONS, 2016). While an estimated 20% of the total food produced is lost or wasted, 33 million people cannot afford a quality meal every second day (Eurostat, 2018).

Globally, approximately a third of all food produced for human consumption is lost or wasted (FAO, 2011). FAO’s Food Loss Index (FLI) estimates that globally, around 14 percent of all food produced is lost from the post-harvest stage up to, but excluding, the retail stage

support the fight against climate change (food waste alone generates 8-10% of global greenhouse gas emissions (UNEP Food Waste Index 2021))

...

Factors contributing to food waste include:

-Insufficient shopping and meal planning
-Shopping environment (e.g. promotions like "buy one, get one free" that may lead to impulse buying and over-purchase)
-Misunderstandings about the meaning of "best before" and "use by" date labels leading to edible foods being thrown away
-Insufficient food management skills (e.g. meal preparation, use of food/food ingredients in-stock, use of leftovers)
-Packaging difficult to empty or too large
-Aesthetic considerations (bruised fruit and vegetables etc.)
-Standardised portion sizes in restaurants and canteens
-Difficulty in anticipating the number of customers (a problem for catering services)
-Stock management issues for manufacturers and retailers
-High quality standards (e.g. for produce sold at retail)
-Overproduction or lack of demand for certain products at certain times of the year
-Production errors, products and/or labelling not meeting specifications
-Product and packaging damage (farmers and food manufacturing)
-Inadequate storage/transport at all stages of the food chain including households (e.g. refrigerator temperatures)
-Lack of knowledge and/or misinformation on the environmental, social and financial impacts of food waste
-Low perceived value of food
-Busy lifestyle and conflicting priorities

TADEAS: Nemělo to být před již dávnými lety zakázáno v celé EU? Nebo jsme jen předstihli dobu a "vymlouvali" se na EU?

jeste bych doplnila point z toho Termination Shock, ze ono totiz jeste zalezi na tom, odkud presne se ta sira strili. Sira strilena z Texasu ma jine ucinky nez z Filipin. Nejde o plosne otaceni termostatem, ale o ovlivnovani ruznych casti sveta ruzne. Podle Stephensonova nazoru se kolem toho daji ocekavat solidni valky (jeden stat nekde neco strili a na druhe strane planety to ovlivni monzun atd)

YMLADRIS: zrovna sira je zajimava, protoze v lodni doprave mam za to ze probehlo vyrazny odsireni, coz je jeden z tech aerosol masking efektu, tj. odsirujeme, podobne jako budeme elektrifikovat, ale to vede ke zvyseni teploty

TUHO: IPCC is like Stephensonova romanova zapletka (ruzny narody a skupiny chteji a nechteji strilet siru do ovzdusi) is legit

The report says that solar geoengineering “may also introduce novel risks for international collaboration and peace”. It continues:

“Conflicting temperature preferences between countries may lead to counter-geoengineering measures, such as deliberate release of warming agents or destruction of deployment equipment. Game-theoretic models and laboratory experiments indicate a powerful actor or group with a higher preference for SRM may use [aerosol release] to cool the planet beyond what is socially optimal.”

I wrote about this @guardian previously, but fossil fuel influence in the IPCC is a huge issue that pretty much gets ignored at the release of every report:

SHEFIK: jeste jsem zapomnel dodat, ze pokud se opravdu bavime o tom regenerativnim pristupu skrze pastvy, tak vysledky studii z USA jsou o 20-30% mensi produkce. pokud to vztahnu globalne na pesimisticky scenar, tak tretina populace upadne do hladomoru, nebo musim plochy na zemi pro pestovani rozsirit o 30%

a to slo o studii, kde puda, lokace atd. byla vhodna na regenerativni pastvu. nejsem odbornik, ale predpokladam, ze ne vsude je tenhle pristup mozny, pripadne rozdily produkce mohou byt hlubsi
