    TUHOKlimaticka zmena / Thank you so much for ruining my day


    "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 panic. I want you to feel the fear I feel every day. And then 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."

    “We’ve got to stop burning fossil fuels. So many aspects of life depend on fossil fuels, except for music and love and education and happiness. These things, which hardly use fossil fuels, are what we must focus on.”

    A nejde o to, že na to nemáme dostatečné technologie, ty by na řešení použít šly, ale chybí nám vůle a představivost je využít. Zůstáváme při zemi, přemýšlíme až moc rezervovaně. Technologický pokrok to sám o sobě nevyřeší. Problém jsme my, ne technologické nástroje.

    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?

    Savory Institute


    Denmark recently became the first country in the world to put a tax on livestock emissions. The tax will go into effect in 2030, and after a 60% tax break is applied, farmers will end up paying 120 krone ($17) per tonne of CO2-equivalent coming from their livestock, which will eventually rise to 300 krone ($43) per tonne in 2035.

    This move comes on the heels of other measures the Danish government has implemented in recent years to reduce emissions and meet climate goals and, given that agriculture is one of Denmark’s largest sources of emissions — with pork and dairy being their largest industries — this is an opportunity to make some headway towards those goals.

    We at Savory are particularly disappointed in this tax given that our new Savory Foundation — which focuses on funding large-scale grassland regeneration projects around the world — is based in Denmark, but more than that, we have serious concerns with regards to how this new tax makes no effort to incentivize a transition towards carbon-sequestering forms of regenerative grazing.

    Yes, our global agricultural system is massively flawed and contributes significant amounts of greenhouse gases into the atmosphere, but this is a blanket tax on ALL forms of livestock management that makes no differentiation between land-degrading carbon-emitting forms of production or land-regenerating carbon-sequestering forms of livestock production.

    If Denmark really wanted to incentivize a transition towards a more sustainable livestock industry — which we agree is needed — they could create a sliding scale for this tax so that regenerative farmers who are improving soil health and sequestering carbon aren’t penalized. This could be accomplished either through soil samples analyzed in a lab — even though that would be costly to producers so ideally would be subsidized by the government — or modeling based on the latest research of what’s possible, not just average emissions of the typical producer which is the basis for this tax.

    Still, even if we were to expand the conversation from just emissions to one that also includes drawdown, the focus on greenhouse gases is a reductionist view that misses the forest for the trees. The climate crisis is intrinsically tied to our global loss of biodiversity, our broken water cycles that amplify droughts and flooding, and our impoverished soils, rural communities, food systems, and everything in between.

    At the intersection of all these issues is ecosystem function, so why do we only ever hear about carbon? The global narrative surrounding climate change would be best served by a shift towards restoring ecosystem function. Imagine an alternate world where Denmark's new tax was one that took a more holistic look at ecosystem function — assessing not just carbon but also biodiversity and water-holding capacity — and rather than penalizing everyone involved it paid farmers who demonstrated positive improvements to their ecosystem processes?

    1 in 5 new car sales globally were EVs in 2023, and that's curbed oil demand – IEA
    https://electrek.co/2024/03/02/1-in-5-new-car-sales-globally-in-were-evs-in-2023-oil-demand-iea/

    The bad news is that energy-related emissions rose in 2023. But the good news is that continued expansion of clean energy technologies meant that global energy-related emissions rose less strongly than in 2022, even as total energy demand growth accelerated.

    Emissions increased by 410 million tonnes, or 1.1%, in 2023 – compared with a rise of 490 million tonnes the year before – taking them to a record level of 37.4 billion tonnes.

    An exceptional shortfall in hydropower due to extreme droughts in the US, China, and several other economies resulted in over 40% of the rise in emissions in 2023 as countries turned largely to fossil fuels to plug the gap. Had it not been for the unusually low hydropower output, global emissions from electricity generation would have declined in 2023, making the overall rise in energy-related emissions significantly smaller.

    ...

    Advanced economies saw a record fall in their emissions in 2023 even as their GDP grew. Their emissions dropped to a 50-year low while coal demand fell back to levels not seen since the early 1900s.

    Risotto crisis: the fight to save Italy’s beloved dish from extinction | Rice | The Guardian
    https://www.theguardian.com/environment/2024/feb/29/risotto-crisis-the-fight-to-save-italys-beloved-dish-from-extinction-aoe


    In 2022, the worst drought in 200 years hit the Po, Italy’s longest river. The waterway forms the lifeblood of a complex web of canals built between the Middle Ages and the 1800s, which serve as the paddy fields’ main source of irrigation. That year, Italy lost 26,000 hectares (64,000 acres) of rice fields, according to Ente Nazionale Risi, the national rice authority, and rice production dropped by more than 30%. Last year, the drought persisted and the crop from another 7,500 hectares of rice fields was lost.

    Today, rice farmers struggling to recover from the impact of the drought face an uncertain future. “The higher the temperatures, the more frequent and intense these extreme events will be,” says Marta Galvagno, a biometeorologist at the Environmental Protection Agency of Aosta Valley.

    Over the past two years, Ferraris, like other farmers in the area, has tried to diversify his crops to reduce the risks brought by the climate crisis. He has reduced the acreage dedicated to paddies and started to grow crops such as maize, that require less water.

    “The climate is changing and I am afraid there will be other droughts,” says Ferraris, whose farm lost about €150,000 [£129,000] in 2022. Rice remains his biggest crop, however. Recently, he has started monitoring snowfalls in the Alps and checking the water levels in Lake Maggiore every day. “It’s hard to sleep at night,” he says.

    Ferraris is particularly worried about the production of carnaroli classico, a refined rice variety. Thanks to its ability to resist high cooking temperatures and absorb flavours, carnaroli is considered the “king of risotto”, but it is also extremely delicate and vulnerable to changes in the climate.

    A Revelation About Trees Is Messing With Climate Calculations | WIRED
    https://www.wired.com/story/a-revelation-about-trees-is-messing-with-climate-calculations/

    In a paper published this month in Science Advances, Dada’s team establishes a new heavy hitter in cloud creation: a kind of chemical released by trees. Trees emit natural volatiles like isoprene and monoterpenes, which can spark cloud-forming chemical reactions. Dada’s new work focuses on an overlooked class of less abundant volatiles called sesquiterpenes, which smell woody, earthy, citrusy, or spicy, depending on the molecule and type of plant or microbe that emits them.

    The team shows that sesquiterpenes are more effective than expected for seeding clouds. A mere 1-to-50 ratio of sesquiterpene to other volatiles doubled cloud formation.
    ...
    This research could help refine estimates of what the atmosphere was like before industrialization. Maybe we’ve been undercounting the world’s aerosol population by overlooking a large portion of those that come from trees. If so, climate models will need retooling.
    ...
    Lab tools have only recently become sensitive enough to understand which ones contribute the most.
    ..
    But scientists have trouble simulating just how many aerosols should be accounted for in models. “It’s been a long-standing problem,” Fan says. “A lot of climate models overestimate anthropogenic aerosol forcing.” Perhaps that is because they are underestimating the prevalence of natural aerosols—from microbes, plants, and trees—before the industrial revolution. “Maybe what we're using as our reference point may actually not be as low-aerosol as we thought,” agrees Zuidema.
    ....
    For example, heat stress, extreme weather, and droughts cause plants to release more biogenic volatiles—which seed more clouds. Deforestation and heat stress are pushing treelines to migrate to higher altitudes and latitudes. That affects where clouds form.

    “It’s a feedback loop,” Dada says. “The climate is affecting the cloud formation, and the clouds are affecting the climate.”

    Why we need a new economics of water as a common good
    https://www.nature.com/articles/d41586-023-00800-z

    Today, the sector concentrates on flows of ‘blue’ fresh water — liquid that runs off the land and is stored in rivers, lakes, reservoirs and underground aquifers. Utilities capture and extract this water locally for drinking and sanitation, agricultural irrigation and industry. They assume it will be continually replenished, naturally, within historical ranges. In many places, that premise already no longer holds.

    Each 1 °C of global warming increases global mean precipitation by 1–3%, and it could rise by up to 12% by the end of the century compared with the period 1995–20141. The impacts will be felt unevenly, with the frequency and severity of both floods and droughts rising. Deforestation, land degradation and infrastructure development are also altering precipitation patterns and affecting where water comes from and ends up2. Excessive extraction for irrigation and industry is aggravating water shortages in river basins, from the Colorado in the United States and the Yangtze in China to the Murray–Darling in Australia.

    To meet these growing challenges, water must be recast as a global common good. That means states establishing an obligation under international law to protect the global water cycle for all people and generations, and acknowledging that actions in one place have impacts in another — for instance, that deforestation in Brazil affects rainfall in Peru. It means assessing the role and economic value of not just blue fresh water, but also ‘green’ water that is held in the air, biomass and soils. And it means governments and the private sectors reformulating their roles and responsibilities, to develop objectives, policies and funds that can reshape markets and better manage global water supplies.

    Water has to become a common good – two new reports show — Potsdam Institute for Climate Impact Research
    https://www.pik-potsdam.de/en/news/latest-news/water-has-to-become-a-common-good-2013-two-new-reports-show

    „We are now pushing the global water cycle out of balance, undermining the source of all freshwater – precipitation – upon which societies are completely dependent on,” Johan Rockström explains.

    The 32-pages GCEW report titled Turning the Tide: A Call to Collective Action, marks the first time the global water system has been scrutinized comprehensively as well as its value to countries — and the risks to their prosperity if water is neglected.

    The majority of countries depend on the evaporation of water from neighboring countries for about half of their water supply. This "green" water is held in soils and transpired from forests and other ecosystems. Countries are not only interconnected by transboundary blue water flows but also through green water, i.e., atmospheric green water flows of water vapor, flows which extend far beyond traditional watershed boundaries.

    Water is not just a casualty but also a driver of the climate crisis. Extreme water events cause an immediate loss of carbon uptake in nature. Droughts lead to fires and massive loss of biomass, carbon, and biodiversity. The loss of wetlands is depleting the planet's greatest carbon store, while the drop in soil moisture is reducing the terrestrial and forest ecosystem's ability to sequester carbon.

    Klimatologie na MUNI
    Česká zemědělská produkce zažila za posledních 2 000 let výrazné extrémy, které zahrnují období, pro něž neexistuje analogie ani v současnosti. To je hlavní závěr článku od Maxe Torbensona, který s týmem dalších odborníků rekonstruoval hydroklimatické podmínky vegetačního období na J ČR a SV Rakouska na základě izotopů uhlíku a kyslíku v letokruzích stromů.
    Potvrdil mj. výraznou suchou periodu v rámci středověké klimatické anomálie (920-1000) i na poč. 16. stol., jakož i vlhká období v průběhu 3., 5. a 7. stol. Dlouhodobě pak směřuje náš region k současným teplejším a sušším podmínkám.

    Central European agroclimate over the past 2,000 years
    Central Europe has experienced a sequence of unprecedented summer droughts since 2015, which had considerable effects on the functioning and productivity of natural and agricultural systems. Placing these recent extremes in a long-term context of natural climate variability is, however, constrained by the limited length of observational records. Here, we use tree-ring stable oxygen and carbon isotopes to develop annually resolved reconstructions of growing season temperature and summer moisture variability for central Europe during the past 2,000 years. Both records are independently interpolated across the southern Czech Republic and northeastern Austria to produce explicit estimates of the optimum agroclimatic zones, based on modern references of climatic forcing. Historical documentation of agricultural productivity and climate variability since 1090 CE provides strong quantitative verification of our new reconstructions. Our isotope records not only contain clear expressions of the Medieval (920-1000 CE) and Renaissance (early 16th century) droughts, but also the relative influence of temperature and moisture on hydroclimatic conditions during the first millennium (including previously reported pluvials during the early 3rd, 5th, and 7th centuries CE). We conclude, Czech agricultural production has experienced significant extremes over the past 2,000 years, which includes periods for which there are no modern analogues.

    The UK can build a reliable, secure and cost-effective electricity system that is decarbonised by 2035, says the government’s advisory Climate Change Committee (CCC).
    The CCC’s new report is based on new hour-by-hour modelling of the country’s electricity system out to 2035, which includes stress-tests of how it could ride out extended “wind droughts”.
    In effect, the report is a 131-page answer to the question often posed by those sceptical of climate action: “But what about when the wind does not blow and the sun does not shine?”

    ‘I am an optimistic person’: the scientist who studies climate catastrophes | Climate crisis | The Guardian
    https://www.theguardian.com/environment/2022/dec/29/i-am-an-optimistic-person-the-scientist-who-studies-climate-catastrophes

    “He said to me: ‘Look, we have this large ensemble of climate models here, do something with it.’

    “So I was handed this huge gathering of data, and what that allows you to do is build statistics about rare and extreme events.”

    Otto was armed with the information which would lead her a few years later, with her late colleague Geert Jan van Oldenborgh, to create the world’s first climate attribution unit to examine to what extent human driven climate change is responsible for extreme heatwaves, droughts and floods.

    The journey from the creation of the World Weather Attribution unit to its current iteration, began with a paper Otto and Oldenborgh wrote on a heatwave in Russia in 2010. It was a classical academic paper, peer reviewed and published long after the event.

    But when Heidi Cullen, one time chief scientist at the NGO Climate Central, suggested the work would be more powerful if it could be carried out faster, it was a breakthrough moment. “There was no reason we shouldn’t be able to do it faster,” said Otto. “We had the methodology that in principle doesn’t take a huge amount of time technically to run, so we could do it.”

    Otto’s conclusions now come at speed, but are still written within the structure of scientific rigour and the available evidence. A great part of the work is communicating to the wider public and politicians the dangers of extreme weather and the message, most crucially, that it is being created by us.

    ...

    . “One of the biggest scientific surprises for me this year was the floods in Nigeria because there was such a huge climate change impact,” said Otto. “They were made 80 times more likely as a result of climate change. That makes me think: ‘Oh wow, there is really a lot that we don’t understand in Africa’.”

    La Niña's global effect

    La Niña occurrences have a devastating global impact because of its effect on weather and climate, Richard Seager, Ph.D., a research professor at Lamont-Doherty Earth Observatory of Columbia University, told ABC News.

    The weather has caused droughts in North and South America and equatorial eastern Africa. La Niña is also linked to floods in Asia, such as the devastating floods Pakistan has endured since June, Seager said.

    NOAA forecasts that the expected La Niña winter season, which is from December 2022 to February 2023, in the U.S. won't be atypical, as the northern Plains, Rockies and Pacific Northwest will also experience cooler temperatures; the South will be hotter than normal and the East Coast may be warmer than it usually is during that time of the year, according to L'Heureux.
