2020 Changes in North Atlantic atmospheric circulation in a warmer climate favor winter flooding and summer drought over Europe
https://journals.ametsoc.org/view/journals/clim/aop/JCLI-D-20-0311.1/JCLI-D-20-0311.1.xml

Our paper “Changes in North Atlantic atmospheric circulation in a warmer climate favor winter flooding and summer drought over Europe” is now released online in Journal of Climate:

We used a very high resolution climate model (GFDL CM2.6: gfdl.noaa.gov/cm2-6/) to assess changes in atmospheric circulation patterns under an experiment of increasing carbon dioxide concentrations

The high resolution of the model allows for mesoscale oceanic eddies to be resolved and it has a realistic representation of the AMOC. This is important for the ocean-atmosphere interactions that play a significant role in forming the dominant atmospheric circulation patterns

...

we find robust changes in certain atmospheric circulation patterns over the North Atlantic

In winter (and particularly in February), zonal regimes (NAO+ like) are increasing by ~30% in frequency in the 2xCO2. In summer (and particularly in August), Atlantic Ridge, a high-pressure system off the UK coast, is increasing by ~60%

Those robust changes in a warmer world may have great implications for European climate. In winter the increase of zonal circulation is linked to increased rainfall over northwestern Europe, increasing the risk of flooding in the area

In summer, the increase of the AR is linked to less precipitation and longer dry spells over western and central Europe, contributing to higher drought risk. Those dynamical changes act supplementary to the thermodynamic effects of a warming world, exacerbating the impacts

LINKOS: jasne, neni to cernobily. ja reagoval konkretne na desertifikaci, na kterou si narazel. spolu se skotem, nebo podobnejma lokalnima zviratama uchovavas prirodu a to daleko vic nez kdyz budujes lany vyoranejch poli

pro primarni obzivu lidstva fandim hydro/aero/aquaponii .) a nejaky maso se v tom klidne schova. pro me za me umely.

...nedavno sem mel burger z cervu (kosik.cz, mrazeny, bohuzel z nemecka) a byl vybornej.

SHEFIK: tak vidíš a ta studie ti i řekne jaké to má limity, což u mám dojem je docela problém. On se tam ten substrát se zivinama nebere jen tak. Možná mluvíš o něčem jiném, ale já myslel, že to zemědělství nás má taky uživit. A to prostě při takové spotřebě jakou máme na západě není možný, a už absolutně to není možný, když se na nás standart budou postupně chtít dostat lidi po celé planetě. A o tom mluví, není možné udělat to tak aby to více plodilo, více chytlo co2, neprodukovalo to metan a ještě sme měli více prostoru pro divokou přírodu. Samozřejmě to jde dělat líp, ale ne vždy to je něco za něco.

LINKOS: me v tomhle tematu docela zmenil nazor carbon cowboys. tusim, ze to byl dil: one hundred thousand beating hearts

kde je videt, ze skot dokaze z "pouste" udelat po par letech znovu fungujici ekosystem, vcetne navratu dalsi fauny a biodiverzity. tohle ti zadnej traktor ani barel NPK nezaridi (resp. za obrovskyho usili, nakladu a vstupu)

a ono to ma logicky opodstatneni, neni moc co na tom studiema rozporovat. ze zadku jim proste pada teplej a vlhkej substrat s zivinama, vcetne semen. co vic by si regenerace prirody mohla prat

2019 Toward a General Theory of Societal Collapse: A Biophysical Examination of Tainter’s Model of the Diminishing Returns of Complexity
https://link.springer.com/article/10.1007/s41247-018-0049-0

The collapse of large social systems, often referred to as “civilizations” or “empires,” is a well-known historical phenomenon, but its origins are the object of an unresolved debate. In this paper, we present a simple biophysical model which we link to the concept that societies collapse because of the “diminishing returns of complexity” proposed by Tainter (The collapse of complex societies, Cambridge University Press, Cambridge, 1988). Our model is based on the description of a socio-economic system as a trophic chain of energy stocks which dissipate the energy potential of the available resources. The model is based on the idea that we observe that the exploitation of a non-renewable resource stock (“production”) has a strongly nonlinear relation with the complexity of the system, assumed to be proportional to the size of the stock termed “The Economy” (or “capital”), producing various trajectories of decline of the economy, in some cases rapid enough that they can be defined as “collapses.” The evolution of the relation of production and the economy produces a curve similar to the one proposed by Tainter, for the decline of a complex society

2020 We need to (find a way to) talk about … Eco-anxiety
https://www.tandfonline.com/doi/abs/10.1080/02650533.2020.1844166?journalCode=cjsw20

Eco-anxiety may not be new, but could now be seen as an emergent phenomenon attracting increasing attention as public awareness about the climate and bio-diversity crisis grows. There may also be some generational differences in how we respond emotionally, with children often talking about feelings framed by their experience of adult misunderstanding or inaction.

What often scares children the most is how they see the ‘adult world’ failing to take sufficient urgent action on these threats, whilst at the same time dismissing, criminalising, pathologising and patronising their feelings and voices. Children and young people are increasingly taking centre stage in protests about the need to take urgent action, whilst simultaneously often being the focus of society’s anxieties about the psychological impact of the crises; ‘we mustn’t frighten the children’.

This paper focuses on children and young people’s perspectives; introducing eco-anxiety, drawing on clinical practice examples, research findings and finally offering conceptual frames to help us broaden and deepen our understanding of this evolving syndrome.

TADEAS: budes prednaset? :)

SHEFIK: jj TADEAS

LINKOS: je to pro me naprosto pochopitelny.

TADEAS: ono je taky dost pravděpodobný, že to množství masa co sníme si nebudem ani moci dovolit až ho začnou jist národy co teď bohatnou. Nechápu proč je pro tebe tak nepochopitelný, že jej jíme nejvíce v historii a je to špatně

LINKOS: stejne jako je ma elektrina. mame snizovat spotrebu elektriny, protoze neumime zmenit zpusoby vyroby? hned.

a ne, neodpustim si to, protoze je to fatalne mylny mysleni s tragickejma dusledkama.
