    A groundbreaking study of U.S. population data suggests rising atmospheric carbon dioxide is already altering human blood chemistry, potentially reaching the limits of healthy ranges within decades.
    In a striking revelation that extends the threat of climate change deep into human biology, scientists have discovered that rising global CO2 levels may already be shifting our blood chemistry.
    Analyzing over two decades of U.S. health data from the National Health and Nutrition Examination Survey, researchers tracked blood markers in thousands of Americans between 1999 and 2020.
    They found that as atmospheric CO2 climbed from 369 to over 420 parts per million, average serum bicarbonate levels—which help maintain the body's acid-base balance—rose by seven percent, while calcium and phosphorus levels steadily declined. This mirroring effect suggests our bodies are actively trying to compensate for an atmosphere changing faster than we can adapt.
    While these subtle physiological shifts do not mean immediate illness, researchers warn of long-term consequences, particularly for children who face a lifetime of cumulative exposure. Projections show that if current emissions trends continue, average human bicarbonate levels could push past the boundaries of today's accepted healthy range within 50 years, while vital minerals like calcium and phosphorus may fall to worrisome lows.
    These findings demand a major shift in how we view climate policy. CO2 is no longer just an environmental metric or weather driver—it is a long-term public health variable that directly threatens human biology, underscoring an urgent medical incentive to curb emissions.

    SHEFIK: no je to zasadni otazka. ten porad dokola opakovany "problem" je nedostatecne komplexne formulovany a realizovany "boj o preziti" :)

    teplo ke dlouho vyreseny problem, absence tepla je recentni inovace, milá evropa to jiste brzy prijme vstric existencialnim vyzvam :)


    Claude:

    It's deeply asymmetric, and the reason is thermodynamic rather than technological. Heat is what every energy conversion produces as waste — friction, combustion, metabolism, anything. You cannot avoid making heat. Cold is not a substance you can make; it's the absence of heat, so "making cold" means pumping heat up a gradient, which the second law says requires work. A caveman with sticks gets warmth for free as a byproduct. There is no equivalent trick for cooling.



    So pre-industrial cultures had only indirect routes, all with hard limits:



    • Evaporative cooling — wet cloth, porous clay pots (zeer), Persian windcatchers over water channels. Powerful but useless in humid air, which is exactly where cooling is most needed for survival.
    • Radiative cooling to the night sky — Persian and Indian ice-makers filled shallow trays on clear dry nights and got ice even when the air stayed above freezing, because the sky at night is effectively a 3 K heat sink through the infrared window.
    • Harvest and store — yakhchāls, European icehouses, and the 19th-century Boston ice trade shipping New England pond ice to Calcutta. This is thermal logistics, not refrigeration.
    • Endothermic chemistry — dissolving saltpetre or salts in water; used to chill wine in Mughal India and Renaissance Italy. Small scale, consumable, expensive.
    • Architecture — thermal mass, courtyards, shading, orientation. Reduces heat gain rather than removing heat.


    Actual on-demand cooling arrived astonishingly late. Cullen demonstrated it in 1755, Perkins patented a vapour-compression cycle in 1834, Carré and Linde made it industrial in the 1860s–70s, and Carrier's 1902 machine — invented to control humidity in a printing plant, not for human comfort — began air conditioning. Fire predates that by roughly 800,000 years.



    The demographic consequence is real: humid tropical regions stayed economically and population-wise constrained far longer than cold ones, and the American Sun Belt only boomed after cheap AC. Lee Kuan Yew called air conditioning the invention that made development in the tropics possible, and it's not obviously hyperbole.

    TADEAS: urcite by se neco na leto naslo, treba matova pomazanka a jeskyne misto opalovaku a koupaliste

    Ale kdyby vsichni nosili praturi kuzi, uz by problem s oteplovanim nebyl, vse by bylo v souladu s prirodou, neb by lidi vezsinu casu resili opravy pomoci dvojityho svu kosti, misto diskuznich for na internetech :)

    (Topné) klimatizace poháněné přebytky z FVE nejen, že v těch vedrech celkem představujou dobrej use case pro tu solární energii, ale ještě mají potenciál vlastně převést jarní topnou sezónu právě na energii z OZE. Ale zase bylo by blbý, kdyby to někdo interpretoval tak, že ten problém vůbec neexistuje...

    Evropa si chtě nechtě musí zvykat na extrémní teploty. Jedna z věcí, kterou ale nedávná vlna veder ukázala, byla nepřipravenost veřejné infrastruktury včetně nemocnic. Ve Francii se z toho stalo žhavé politické téma a předmět téměř kulturní války. Jaká vyvstávají etická dilemata kolem používání klimatizace v době, kdy lidstvo čelí změně klimatu, za kterou stojí právě energeticky nešetrná lidská činnost?

    "Just stay inside"

    Y'all!
    Our farm is outside.
    The crops are outside.
    The food grows in the soil in a field. Outside.
    It's acres upon acres of open fields.
    Not just on our farm, but on every farm in Michigan.
    We appreciate the sentiment, but we cannot just 'stay inside'.
    And neither can our fellow farmers, ranchers, orchardists, and other food-growing colleagues.
    In Michigan, we are in the middle of our PEAK season.
    Across all of Michigan, there are hundreds of millions of dollars of crops growing right now. Outside.
    That's our livelihoods. Our life's work. The whole enchilada.

    I'm sorry, but we're going to be outside.
    I'm sorry that we have to be. We didn't ask for this.
    We're taking as many precautions as we can.
    And I'm sorry if seeing our team working outside makes you uncomfortable.
    Our nation has an unfortunate history of hiding how our food is grown and the people who grow it. Our farm has prided itself on being transparent with our customers. And we speak for all farmers when we tell you that we will continue to show up.
    Right now, there are tens of thousands of agricultural workers in the state of Michigan who are combatting incredibly challenging conditions to show up to grow your food. Please support your local farmers. Don't tell them to wait inside. That's not how this works.

    The more this week has progressed, the less sure we are that people know where their food comes from.

    Obviously we WANT to stay inside, but then the food would rot in the field. The market shelves would be empty. Our community would lack access to safe, organic, local food.

    The cruel irony is, in the midst of a parasite-infested-lettuce outbreak, our work on a local level is more important than ever. And at the same time, it is more hazardous than ever.

    Our region was #1 in the world for worst air quality this week. That's the wrong competition to be in first place.

    We have limited outdoor activity to only the most essential tasks. We have masks available for all staff. We have rearranged our schedules and our to-do lists.

    But when you come into our Market, you are going to find tables and shelves absolutely overflowing with abundance. And that is because of the work we're doing outside. Everyday. For you.

    Today, like everyday, we are incredibly grateful for our team. Everyone has stepped up to tackle this week with a level of gumption and can-do spirit that is rare these days. Those of us who are unable to safely work in these conditions are at home or inside. Those of us who are able to carry on, are showing up and stepping up.

    And deep down we know, that all of the things we are putting off for now, the so-called 'non-essentials', are piling on to our to-do list after the skies clear. Whenever that is. And the sheer amount of catching up that looms is almost more intimidating than the apocalyptic skies we are working under right now.

    On behalf of all Michigan farmers, thank you for your support. We're doing the best we can with the hand we've been dealt. If you need to find us, we'll be out here growing your food.
