    Prairies on Fire in Montana Amid a Record December Heat Wave
    https://www.nytimes.com/2021/12/02/us/montana-wildfire-drought.html

    Record-high temperatures and powerful winds have sparked a series of unusual December prairie fires in Montana, one of a series of late-season fires across the country amid an unusually warm approach to the winter season.

    ...

    The fires came as an unusual heat wave broke records across large portions of the United States and Canada. Temperatures from the Great Plains to the Mid-Atlantic were 20 to 30 degrees above normal for early December, reaching into the 60s and 70s, the National Weather Service said.

    TUHO: A jeste vecerni nadseni zavrsuju tipem od Konvicky (jo od toho Konvicky :D) na otvirak do Zimovovi prace:

    At the last deglaciation Earth’s largest biome, mammoth-steppe, vanished. Without knowledge of the
    productivity of this ecosystem, the evolution of man and the glacialeinterglacial dynamics of carbon
    storage in Earth’s main carbon reservoirs cannot be fully understood. Analyzes of fossils 14C dates and
    reconstruction of mammoth steppe climatic envelope indicated that changing climate wasn’t a reason for
    extinction of this ecosystem. We calculate, based on animal skeleton density in frozen soils of northern
    Siberia, that mammoth-steppe animal biomass and plant productivity, even in these coldest and driest of
    the planet’s grasslands were close to those of an African savanna. Numerous herbivores maintained
    ecosystem productivity. By reducing soil moisture and permafrost temperature, accumulating carbon in
    soils, and increasing the regional albedo, mammoth-steppe amplified glacialeinterglacial climate variations. The re-establishment of grassland ecosystems would slow permafrost thawing and reduce the
    current warming rate. Proposed methods can be used to estimate animal density in other ecosystems.

    A Realistic Path to a Bright Future
    https://mailchi.mp/caa/a-realistic-path-to-a-bright-future
    3 December 2021
    James Hansen

    Why is nobody telling young people the truth? “We preserved the chance at COP26 to keep global warming below 1.5°C.” What bullshit! “Solar panels are now cheaper than fossil fuels, so all we are missing is political will.” What horse manure! “If we would just agree to consume less, the climate problem could be solved.” More nonsense!

    Young people, I am sorry to say that – although the path to a bright future exists and is straightforward – it will not happen without your understanding and involvement in the political process.
    ...
    Do not feel sorry for yourself or get discouraged. Yours is not the first generation to be dealt a bad hand. Some were born into great depressions. Some were sent to fight in world wars or senseless conflagrations in far away places such as Viet Nam or Iraq. Your battle will cover more years. Nature has a long time scale in its response to human-caused forces, and it takes time to alter human-made energy systems. But your cause is noble – your challenge is nothing short of guiding humanity and other life on our planet to a bright future.
    ...
    The next 10 years – the fourth decade since the adoption of the Framework Convention on Climate Change in 1992 – must be the decade in which young people take charge of their own destiny.

    OTZ: Nevypadá, ale je.

    Simulations of the climate response if the sun did fall to Maunder Minimum levels find that the decrease in temperature from the sun is minimal compared to the warming from man-made greenhouse gases (Feulner 2010). Cooling from the lowered solar output is estimated at around 0.1°C (with a maximum possible value of 0.3°C) while the greenhouse gas warming will be around 3.7°C to 4.5°C, depending on how much CO2 we emit throughout the 21st century

    The drought ravaging East African wildlife and livestock - BBC News
    https://www.bbc.com/news/av/world-africa-59513118

    At least 26 million people are struggling for food following consecutive poor rainfall seasons in the Horn of Africa.

    Drought conditions in northern Kenya, much of Somalia and southern Ethiopia are predicted to persist until at least mid-2022, putting lives at risk.

    The situation is already so bad that wild animals are dying in their hundreds and herders are reporting losses of up to 70% of their livestock.

    Humans Are Doomed to Go Extinct - Scientific American
    https://www.scientificamerican.com/article/humans-are-doomed-to-go-extinct/

    As a paleontologist, I take the long view. Mammal species tend to come and go rather rapidly, appearing, flourishing and disappearing in a million years or so. The fossil record indicates that Homo sapiens has been around for 315,000 years or so, but for most of that time, the species was rare—so rare, in fact, that it came close to extinction, perhaps more than once. Thus were sown the seeds of humanity’s doom: the current population has grown, very rapidly, from something much smaller. The result is that, as a species, H. sapiens is extraordinarily samey. There is more genetic variation in a few troupes of wild chimpanzees than in the entire human population. Lack of genetic variation is never good for species survival.

    What is more, over the past few decades, the quality of human sperm has declined massively, possibly leading to lower birth rates, for reasons nobody is really sure about. Pollution—a by-product of human degradation of the environment—is one possible factor. Another might be stress, which, I suggest, could be triggered by living in close proximity to other people for a long period. For most of human evolution, people rode light on the land, living in scattered bands. The habit of living in cities, practically on top of one another (literally so, in an apartment block) is a very recent habit.

    Another reason for the downturn in population growth is economic. Politicians strive for relentless economic growth, but this is not sustainable in a world where resources are finite. H. sapiens already sequesters between 25 and 40 percent of net primary productivity—that is, the organic matter that plants create out of air, water and sunshine. As well as being bad news for the millions of other species on our planet that rely on this matter, such sequestration might be having deleterious effects on human economic prospects. People nowadays have to work harder and longer to maintain the standards of living enjoyed by their parents, if such standards are even obtainable. Indeed, there is growing evidence that economic productivity has stalled or even declined globally in the past 20 years. One result could be that people are putting off having children, perhaps so long that their own fertility starts to decline.

    An additional factor in the shrinking rate of population growth is something that can only be regarded as entirely welcome and long overdue: the economic, reproductive and political emancipation of women. It began hardly more than a century ago but has already doubled the workforce and improved the educational attainment, longevity and economic potential of human beings generally. With improved contraception and better health care, women need not bear as many children to ensure that at least some survive the perils of early infancy. But having fewer children, and doing so later, means that populations are likely to shrink.

    The most insidious threat to humankind is something called “extinction debt.” There comes a time in the progress of any species, even ones that seem to be thriving, when extinction will be inevitable, no matter what they might do to avert it. The cause of extinction is usually a delayed reaction to habitat loss. The species most at risk are those that dominate particular habitat patches at the expense of others, who tend to migrate elsewhere, and are therefore spread more thinly. Humans occupy more or less the whole planet, and with our sequestration of a large wedge of the productivity of this planetwide habitat patch, we are dominant within it. H. sapiens might therefore already be a dead species walking.

    The signs are already there for those willing to see them. When the habitat becomes degraded such that there are fewer resources to go around; when fertility starts to decline; when the birth rate sinks below the death rate; and when genetic resources are limited—the only way is down. The question is “How fast?”
