Američané mnohem méně jezdí auty a utlumení průmyslu i těžby způsobilo mnohem menší emise skleníkových plynů. Od doby, kdy v březnu začala platit opatření proti nemoci covid-19, se USA podle nové zprávy Road Ecology Center Kalifornské univerzity v Davisu začaly blížit splnění klimatických cílů pařížské dohody.

But a key question for climate change is what impact this has had on the overall amount of CO2 in the atmosphere – the principal driver of global temperature rise. In our analysis for Carbon Brief, we assess whether the global drop in emissions will have a noticeable impact on atmospheric CO2 concentrations this year.

The researchers say that projections from one of the leading models, known as CESM2 (Community Earth System Model, version 2), are not supported by geological evidence from a previous warming period roughly 50 million years ago.

The researchers used the CESM2 model to simulate temperatures during the Early Eocene, a time when rainforests thrived in the tropics of the New World, according to fossil evidence.

But the CESM2 model projected Early Eocene land temperatures exceeding 55 degrees Celsius (131 degrees F) in the tropics, which is much higher than the temperature tolerance of plant photosynthesis—conflicting with the fossil evidence. On average across the globe, the model projected surface temperatures at least 6 degrees C (11 degrees F) warmer than estimates based on geological evidence.

Holistic Management (HM) is a decision-making framework based on triple bottom line thinking and a proactive approach to managing complexity. Primarily associated with an approach to managing livestock, it has spurred long running and still unresolved debates in rangeland ecology and management. Less studied are the social, cultural, and psychological aspects of HM, which may hold the key to successful ecological outcomes. In this article, we describe the main tenets of HM as conceived by wildlife biologist Allan Savory and address the longstanding and unresolved controversy over its legitimacy. We then provide a meta-analysis that not only provides an up-to-date review of the multidisciplinary evidence and ongoing arguments about HM, but also provides a novel explanation for the controversy—that it is grounded in epistemic differences between disciplines associated with agricultural science that rule out any chance of resolution. We conclude that the way to resolve the controversy over HM is to research, in partnership with ranchers, rangeland social-ecological systems in more holistic, integrated ways. This can account for the full range of human experience, co-produce new knowledge, and contribute to social-ecological transformation.

Co si myslí místní zemědělci. Rozdělení lánů na max 30ha jedné plodiny, vedle nutnost zasít něco jiného, platné od 1/2020. Řeší to něco? Není to jen taková úlitba, která moc nemění, pokud tam stejně jezdí těžká mechanizace, používají se chemikálie, a tak? Mám si to představit tak, že taková křepelka bude mít na poli dvou plodin 50% šanci, že stihne vysedět mladé dřív, než je člověk rozmašíruje? Rozuměla bych, že to má význam, pokud by se část nechala úplně ladem... Nebo když tam bude pás keřů a stromů, kde se neseče.
Není to jen způsob, jak odvrátit kritiku průmyslového zemědělství - však jsme rozdělili lány, co ještě byste chtěli? :/

During the day on both Friday and Saturday, wind and solar combined to deliver more than 100 per cent of demand in South Australia, with the excess being exported to Victoria.
At the time of the 5,000MW record, wind was providing one third of the supply in Victoria, 23 per cent in Tasmania and 16 per cent in NSW, and just 4.2 per cent in Queensland

All species have an environmental niche, and despite technological advances, humans are unlikely to be an exception. Here, we demonstrate that for millennia, human populations have resided in the same narrow part of the climatic envelope available on the globe, characterized by a major mode around ∼11 °C to 15 °C mean annual temperature (MAT). Supporting the fundamental nature of this temperature niche, current production of crops and livestock is largely limited to the same conditions, and the same optimum has been found for agricultural and nonagricultural economic output of countries through analyses of year-to-year variation. We show that in a business-as-usual climate change scenario, the geographical position of this temperature niche is projected to shift more over the coming 50 y than it has moved since 6000 BP. Populations will not simply track the shifting climate, as adaptation in situ may address some of the challenges, and many other factors affect decisions to migrate. Nevertheless, in the absence of migration, one third of the global population is projected to experience a MAT >29 °C currently found in only 0.8% of the Earth’s land surface, mostly concentrated in the Sahara. As the potentially most affected regions are among the poorest in the world, where adaptive capacity is low, enhancing human development in those areas should be a priority alongside climate mitigation.

Ha, tudle knizku od Erica Conwaye, spoluautora skvele "Merchants of Doubt" o dezinformacnich kampanich (nejen) kolem klimatickych zmen, jsem nejak nezaregistroval...

This book offers an informed and revealing account of NASA's involvement in the scientific understanding of the Earth's atmosphere.
Since the nineteenth century, scientists have attempted to understand the complex processes of the Earth's atmosphere and the weather created within it. This effort has evolved with the development of new technologies -- from the first instrument-equipped weather balloons to multibillion-dollar meteorological satellite and planetary science programs.
Erik M. Conway chronicles the history of atmospheric science at NASA, tracing the story from its beginnings in 1958, the International Geophysical Year, through to the present, focusing on NASA's programs and research in meteorology, stratospheric ozone depletion, and planetary climates and global warming. But the story is not only a scientific one. NASA's researchers operated within an often politically contentious environment. Although environmental issues garnered strong public and political support in the 1970s, the following decades saw increased opposition to environmentalism as a threat to free market capitalism.
Atmospheric Science at NASA critically examines this politically controversial science, dissecting the often convoluted roles, motives, and relationships of the various institutional actors involved -- among them NASA, congressional appropriation committees, government weather and climate bureaus, and the military.
