    TUHOKlimaticka zmena / If the fracturing of our once stable climate doesn’t terrify you, then you don’t fully understand it


    "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?
    Ale take jak funguji masove dezinformacni kampane ropneho prumyslu a boj o verejne mineni na prahu noveho klimatickeho rezimu post-holocenu.

    The Fastest Warming on Earth
    https://www.pressenza.com/2024/02/the-fastest-warming-on-earth/

    In the High Arctic, scientists discovered million-year-old methane (CH4) trapped under some of the world’s mightiest glaciers detected via unprecedented groundwater springs. Analyses of 123 springs found CH4 in all but one. As the massive glaciers recede, space opens at the edge of permafrost, releasing ancient methane. This is one more totally unexpected global warming headache.

    Methane detected in the High Arctic puts a big hole in the Global Methane Pledge of more than 100 countries that agreed to cut emissions by 30% by 2030. It’s an add-on that nobody knows how to deal with.

    The High Arctic location is Svalbard, Norway (pop. 2,642) which is the fastest warming region of the planet only 700 miles from the North Pole. Ironically, the fastest warming is the farthest northern human outpost, deep into the Arctic North.

    “On the Dot with David Schechter,” CBS News released a 45-minute film on December 4th, 2023, documenting the warmest place on Earth: Ancient Methane Escaping from Melting Glaciers Could Potentially Warm the Planet Even More.

    As the ice melts, a perilous Russian threat is emerging in the Arctic | Barry Gardiner | The Guardian
    https://www.theguardian.com/commentisfree/2023/jun/13/arctic-russia-nato-putin-climate

    The eight Arctic states – Canada, Finland, Denmark, Iceland, Norway, Sweden, the US and Russia – have long collaborated on scientific research through the Arctic Council, a non-military body. Until now. After Russia’s invasion of Ukraine, Arctic Council meetings ceased. So did cooperation with Russia. This has hampered progress on climate and environmental research and turbocharged the militarisation of the Arctic.

    The success of the Arctic Council depended on its geopolitical balance. It is not a security alliance and has always tried to remain independent from politics. Five of the eight countries were part of Nato; the other three were not. That has now changed. Finland joined Nato in April. Sweden is in the process of joining. Soon, Nato will literally be surrounding Russia in the Arctic.

    To understand why this matters, we must first understand the climate emergency taking place in the region. Summer sea ice has declined by 30% in the past 30 years; 90% of old ice, which is classified as five years old or more, has gone. That ice used to act as the great heat shield for the planet, reflecting back the sun’s rays. But the loss of ice is producing a vicious spiral of heating. The Arctic is now warming three times faster than the global average. This process is called Arctic amplification. It means that scientists now project an Arctic free from summer ice by 2040–45.

    As the ice cover is lost, a trans-polar route is opening to connect east Asia to Europe and the eastern coast of North America. And the ice barrier that once protected Russia’s northern shore will be exposed as never before. Russia represents 53% of the Arctic coastline and the need to protect its northern border as the ice barrier melts is a key national security concern.

    Vladimir Putin already had ambitious plans for the northern sea route, seeking to more than double the cargo traffic. But over the past six years, Russia has also built 475 military sites along its northern border. The port of Severomorsk, on the Kola peninsula, is the base of the country’s northern fleet. In recent years, the Russians have reactivated 50 Soviet outposts in the Arctic and equipped its northern fleet with nuclear and conventional missiles.

    The challenge of all this has not been purely logistical. As the permafrost thaws, the structural base for roads, buildings and other key infrastructure has collapsed. Russia is trying to deploy huge amounts of infrastructure and military capacity to build structures on land that is disintegrating, across roads that are disappearing

    ...

    On a recent visit to the Ny-Ålesund international research station on Svalbard, it was depressing to hear that scientific cooperation with Russia on climate matters has effectively ceased. The Arctic is an environment where cooperation is essential. Arctic science must be done over the long term, and the relationships and trust built up between partners offer predictability and greater stability. In a region that is becoming over-securitised, every opportunity to minimise accidental misunderstandings and avoid a military response should be seized.

    A militarised Arctic would undermine scientific cooperation and pose an existential threat. Somehow, we need a diplomatic effort to separate the politics of war from the imperatives of climate research.

    We have, until yesterday morning, warned of the 3-times faster warming of the Arctic, compared to the Planet. Now we have to make a correction. It is 4 times faster (7 times faster on Svalbard). Implications remain poorly understood.

    Exceptionally warm air temperatures in summer 2022 have caused record melting across Svalbard.
    “The melt anomaly is 3.5 times larger than the 1981–2010 average, and 5 times the interannual variability,” Fettweis said. “Only a changing climate can explain this.”

    Exceptional warming over the Barents area | Scientific Reports
    https://www.nature.com/articles/s41598-022-13568-5

    In our new study in @SciReports we identify a record-high observed warming of up to 2.7 °C per decade over the Barents area

    We have established a comprehensive high-quality dataset on surface air temperature (SAT) observed over the past 20 to 40 years from the Arctic warming hotspot archipelagos Svalbard and Franz Josef Land in the northern Barents area

    Until now, the surface air temperature development of Northern and Eastern #Svalbard has been unexplored. This new dataset provides time series that are longer than those that have been used so far

    From observations: The highest warming rates were found in the Northern and Eastern parts of the Barents area and were up to twice as high than hitherto known in this region from reference station series in the Western and Southern part of Svalbard

    The recently released high-resolution @CopernicusECMWF Arctic Regional ReAnalysis (#CARRA) supported our findings and showed notably greater trends and represented temperature more accurately than the widely used reanalysis ERA5

    From reanalysis: The regional warming rate for the Northern Barents Sea is exceptional on the #Arctic and #global scale and corresponds to five to seven times the global average!

    Both the long-term trend and the interannual variability showed high compliance between the Sea Ice Concentration (SIC, @OSISAF, @Istjenesten) versus Surface Air Temperature (SAT, @Meteorologisk, @CopernicusECMWF) - both locally around the weather stations and regionally

    We demonstrated that the temperature (SAT) increase is strongly linked, both in space and time, to the large reduction of sea ice (SIC) in the Northern Barents Sea

    V Arktidě se děje něco velmi neobvyklého. Na neobvyklé změny upozornil tým biologů. Těmito změnami jsou zárodky rašelinišť, které se začaly objevovat v arktických oblastech, které rychle tají. Díky tomu mohou za polárním kruhem vznikat místa, která budou pohlcovat uhlík z atmosféry.

    (...) Není to ještě rašelina v pravém slova smyslu, ale dalo by se říci, že je to výchozí bod pro její vznik. Pokud tento proces, který vytváří proto-rašeliniště, probíhá ve velké míře, může se na severu objevit neočekávaná zásobárna uhlíku, nebo dokonce rostlinné společenstvo, které zmírňuje klimatické změny,“ uvedla vedoucí výzkumu Minna Välirantová z Helsinské univerzity.

    Tento rezervoár zatím nebyl zahrnut do žádného modelování ekosystémů a atmosféry, protože se tradičně předpokládalo, že žádná nová rašeliniště nevznikají. Jedná se tak možná o takzvaný zpětnovazební jev, kdy planeta reguluje zvyšující se množství uhlíku v atmosféře tvorbou nových rašelinišť.

    They are a gardener’s best friend, good for the soil and a treat for birds. But the humble earthworm may not always be good news, according to a study that suggests invasive earthworms could be making Arctic soils too fertile.
    The earthworm is not typically thought of as an invasive species. “Most parts of Europe have earthworms so we never really saw them as a problem,” says lead researcher Dr Gesche Blume-Werry, an ecologist from the University of Greifswald in Germany. But Blume-Werry and her colleagues realised that “more and more spots in the Arctic have worms because humans brought them there”.
    Earthworms move at around five to 10 metres a year in the Arctic, but human mobility means they can jump from the UK to Svalbard in a single move. They are reaching remote areas by hitchhiking in the treads of people’s shoes, from being used as bait for fishing and in imported soils for gardening. As the Arctic warms, they are able to colonise more areas.
    Early research indicates that the earthworms could have the same effect on Arctic plant productivity as a 3C rise in temperature.

    Through his music, acclaimed Italian composer and pianist Ludovico Einaudi has added his voice to those of eight million people from across the world demanding protection for the Arctic.
    Einaudi performed one of his own compositions on a floating platform in the middle of the Ocean, against the backdrop of the Wahlenbergbreen glacier (in Svalbard, Norway).

    Travelling on board Greenpeace ship Arctic Sunrise on the eve of a significant event for the future of the Arctic: this week's meeting of the OSPAR Commission, which could secure the first protected area in Arctic international waters.
