NYRLEM: btw koukam ze lynnasovi vysla i updatovana verze. ma peknou anotaci ,))

At one degree – the world we are already living in – vast wildfires scorch California and Australia, while monster hurricanes devastate coastal cities. At two degrees the Arctic ice cap melts away, and coral reefs disappear from the tropics. At three, the world begins to run out of food, threatening millions with starvation. At four, large areas of the globe are too hot for human habitation, erasing entire nations and turning billions into climate refugees. At five, the planet is warmer than for 55 million years, while at six degrees a mass extinction of unparalleled proportions sweeps the planet, even raising the threat of the end of all life on Earth.

- ad "mala doba ledova" (aka problematika planetarni vs regionalni):

The Intergovernmental Panel on Climate Change Third Assessment Report considered that the timing and the areas affected by the Little Ice Age suggested largely independent regional climate changes, rather than a globally synchronous increased glaciation. At most, there was modest cooling of the Northern Hemisphere during the period. - https://en.m.wikipedia.org/wiki/Little_Ice_Age

- ad "kdo vybral 1751 nebo 1850 jako referencni a proc"

To better define the Paris Agreement’s commitments, we need to select a suitable starting point for when humans began to influence the climate. However, there is no perfect choice.

Previously, the period 1850-1900 has been used as the historical baseline, but this period includes some large volcanic eruptions and is after greenhouse gas concentrations had already started to rise. We suggest that the earlier period of 1720-1800 is a better choice for this baseline. This is because the major natural factors that also affect Earth’s climate – the levels of solar and volcanic activity – were both at similar levels to today (see Figure 1).

This is important because we want to assess the changes due to human activity, rather than changes because of other factors. For example, the early 1800s were cooled by several large volcanic eruptions and so are unsuitable for a baseline. And before 1720 there was less solar activity and also several large volcanic eruptions. - https://www.climate-lab-book.ac.uk/2017/defining-pre-industrial/

NYRLEM: meles blbosti

TUHO: musime ale zohlednit i odbouravani co2: ionizace, biomasa, sedimenty

NYRLEM: Historicky dluh - CO2 zustava (a ohriva) v atmosfere stovky let pote, co ho do ni vypustis. Krome toho, ze mame vyrazne vyssi kumulativni emise regionalne, stale mame vyssi emise (pres mirny a dlouhodoby snizvoani emisi v poslednich letech). A narozdil od CR tak Cina v poslednich letech karbonizace viditelne slape.

Which countries are historically responsible for climate change?

NYRLEM: "bez dostaku stabilni energie dalsi rozvoj zeme nezajisti." presne tal, s dodatkem, ze bez dostatku stabilniho klimatu a dostatevne funkcnich ekosystemu (ahoj, oceáne) ten rozvoj taky nezajisti.

NYRLEM: Historickym dluhem jsem myslel to, kdy a v jake mire, se emice CO2 produkovaly, protoze se CO2 castecne kumuluje, nebo mozna lepe receno jenom castecne odbourava. A to je arguemnt, ktery pouzivaji rozvojove ekonomiky vzdy: "vy jste si vybudovali pokrocilou ekonomiku s pouzitim fosilnich paliv, a po nas chcete, abychom se jich uplne vzdali?"
CEZ si snizil emise tak, ze prodal uhelne eleketrarny. Udelat to musel, protoze podle pravidel o jednotnem a liberalnim trhu byl CEZ prilis velky pro cesky trh.

NYRLEM: protoze jsme lepsi nez Cina? A taky mame vetsi historicky dluh?
CEZ si snizi emise predevsim tim, ze elektrarny zprivatizoval, coz bylo narizene z EU.

Klimatologie na MUNI
Česká zemědělská produkce zažila za posledních 2 000 let výrazné extrémy, které zahrnují období, pro něž neexistuje analogie ani v současnosti. To je hlavní závěr článku od Maxe Torbensona, který s týmem dalších odborníků rekonstruoval hydroklimatické podmínky vegetačního období na J ČR a SV Rakouska na základě izotopů uhlíku a kyslíku v letokruzích stromů.
Potvrdil mj. výraznou suchou periodu v rámci středověké klimatické anomálie (920-1000) i na poč. 16. stol., jakož i vlhká období v průběhu 3., 5. a 7. stol. Dlouhodobě pak směřuje náš region k současným teplejším a sušším podmínkám.

Central European agroclimate over the past 2,000 years
Central Europe has experienced a sequence of unprecedented summer droughts since 2015, which had considerable effects on the functioning and productivity of natural and agricultural systems. Placing these recent extremes in a long-term context of natural climate variability is, however, constrained by the limited length of observational records. Here, we use tree-ring stable oxygen and carbon isotopes to develop annually resolved reconstructions of growing season temperature and summer moisture variability for central Europe during the past 2,000 years. Both records are independently interpolated across the southern Czech Republic and northeastern Austria to produce explicit estimates of the optimum agroclimatic zones, based on modern references of climatic forcing. Historical documentation of agricultural productivity and climate variability since 1090 CE provides strong quantitative verification of our new reconstructions. Our isotope records not only contain clear expressions of the Medieval (920-1000 CE) and Renaissance (early 16th century) droughts, but also the relative influence of temperature and moisture on hydroclimatic conditions during the first millennium (including previously reported pluvials during the early 3rd, 5th, and 7th centuries CE). We conclude, Czech agricultural production has experienced significant extremes over the past 2,000 years, which includes periods for which there are no modern analogues.
