    TUHOKlimaticka zmena / Destroying the Future Is the Most Cost-Effective
    "Given the sheer enormity of climate change, it’s okay to be depressed, to grieve. But please, don’t stay there too long. Join me in pure, unadulterated, righteous anger."

    "I don’t want your hope. I don’t want you to be hopeful. ... I want you to act. Once you start to act, the hope is everywhere."

    "Our best scientists tell us insistently that a calamity is unfolding, that the life-support systems of the Earth are being damaged in ways that threaten our survival. Yet in the face of these facts we carry on as usual."

    Rostouci hladiny oceanu, zmena atmosferickeho proudeni, zmeny v distribuci srazek a sucha. Zmeny karbonoveho, fosforoveho a dusikoveho cyklu, okyselovani oceanu. Jake jsou bezpecnostni rizika a jake potencialni klady dramatickych zmen fungovani zemskeho systemu?
    Ale take jak funguji masove dezinformacni kampane ropneho prumyslu a boj o verejne mineni na prahu noveho klimatickeho rezimu post-holocenu.

    Za posledních dvě stě let jsme českou říční síť systematicky ničili. Nejprve kvůli mlýnům a plavení dřeva, pak kvůli zemědělství a kolektivizaci, nakonec ve jménu protipovodňové ochrany. Podle digitalizovaných archivních podkladů je dnes upraveno 13 385 km vodních toků a dalších 1 232 km je zatrubněno pod zemí. Celkovou délku říční sítě jsme zkrátili o 30 %. U velkých toků je bilance ještě drastičtější: Labe od Jaroměře po Mělník ztratilo za dvě století 55 % své délky — ze 404 km na pouhých 181 km. Dyje od Drnholce po soutok s Moravou přišla o 36 %.

    Co to znamená v praxi? Narovnané toky proudí rychleji, erodují dno, nerozlévají se do nivy. Zanikly meandry, mrtvá ramena, lužní lesy — celé ekosystémy, které po tisíce let fungovaly jako houba na vodu. Místo živého organismu, který zadržuje vodu, chladí krajinu a živí stovky druhů, máme odvodňovací kanály. Krajina kolem nich vysychá — a vysychá tím rychleji, čím víc se otepluje.

    Datacenters driving US clean energy growth while still threatening climate | Datacenters | The Guardian
    https://www.theguardian.com/us-news/2026/jun/19/datacenters-us-clean-energy-growth-climate

    Datacenters are driving unprecedented growth in the US clean energy industry, paradoxically boosting a sector that was sputtering before the artificial intelligence boom even as AI’s rollout creates immense environmental challenges.

    However, observers caution that while the centers are propelling wind, solar, and other clean energy companies, datacenters remain a climate nightmare.

    Among companies at the leading edge is Nextpower, a utility-scale solar infrastructure producer, which just reported 20% year-over growth and recently purchased datacenter battery producer Prevalon.

    Google, meanwhile, just developed the world’s largest grid-scale battery to power a datacenter in Minnesota, and purchased an energy company with which it is expanding renewable development, including at a new “off the grid” center in Texas that will include wind, solar, batteries, and gas.

    “It looks to me like they’re setting up to be vertically integrated to supply their own electricity, and they’ll drive a lot of development,” Jester said.

    There is some benefit to the larger grid. In Wisconsin, energy regulators don’t have a renewable energy standard guiding their decisions, but are building about 15 wind or solar facilities to accommodate Microsoft and Oracle datacenters, though those also include some natural gas, Jester said.

    “Between the speed to power and the preference by datacenters companies for clean energy,” the renewables made more sense, Jester added. In Michigan, DTE Energy is building a 330 MW battery system instead of building a new gas plant to support a 1.4GW Oracle datacenter, which was the only way to meet Oracle’s timeline. The company will pay for the batteries.

    Jestli teda jeden z hornich deseti Noru zapne obcas v lete klimosku, vs 25 milionovy mesto kontinualne celej rok...

    ‘Mega-consumers’ of food and energy cost environment $5.7tn a year, study finds | Environment | The Guardian
    https://www.theguardian.com/environment/2026/jun/18/mega-consumers-food-energy-damage-cost-environment

    Environmental damages of the top ten percent consumers exceed global climate and biodiversity funding gaps | Communications Sustainability
    https://www.nature.com/articles/s44458-026-00079-x

    The environmental damage bill racked up by the highest-consuming 10% of the world’s population has reached up to $5.7tn a year – larger than the economy of every country except the US and China, a study has found.

    Mega-consumers in this group are concentrated in the global north, accounting for more than half the population of the US and 40-45% of people in the EU.

    The damage tally, which one researcher described as “bonkers”, also exceeds global funding gaps for tackling the climate and biodiversity crises, highlighting how economic priorities remain skewed towards running down the Earth’s life-support systems.

    The most destructive forms of consumption were linked to two main areas: food – particularly red meat, a primary driver of deforestation – and energy, including flights and heating and cooling homes, which typically rely on burning of fossil fuels, such as gas, oil and coal.

    The $5.7tn figure, published in a paper by researchers at University of Oxford and University of Leiden, was calculated by using estimates of the monetary impacts of climate disruption, biodiversity loss, nutrient pollution and freshwater use.

    A new study presented at the Our Ocean Conference in Mombasa has found that 166,000 square kilometres of the world's coral reefs -- around a third of the total -- are particularly "climate-resilient", meaning they have the potential to survive through major ocean warming events.

    Phytoplankton decline hints trouble for north Atlantic food webs - Oceanographic
    https://oceanographicmagazine.com/news/phytoplankton-decline-hints-trouble-for-north-atlantic-food-webs/

    It has linked the declines primarily to rising sea surface temperatures and changes in mixed layer depth – physical properties that control how nutrients and light are distributed in the upper ocean. As surface waters warm, the ocean stratifies into more distinct layers that are less likely to mix vertically, cutting off the supply of nutrients from depth that phytoplankton depend on to grow.

    “While the ocean may appear to be one giant body of water, it is often divided into layers based on temperature,” said Dr Tilstone. “As the ocean warms, these layers become stronger and less likely to vertically mix – a process known as thermal stratification. This matters because the mixing of ocean waters helps transport nutrients from the depths to the surface, where phytoplankton can use them to grow. When that supply is reduced, microalgae productivity can decline.”

    Ohledně baterií. Nejde jen o kapacitu (jasně že určuje dojezd) tu energii tam prostě musíš dostat. U kontejnerové lodě moc nepřichází v úvahu vyměnit baterky a co se projede musíš dobít. Sice ne pokaždé všechno, ale nakonec ano. A déle než na překládku je stání u mola drahé.
