    SHEFIK: Jestli to budou prodavat za 100 Kc / 20 m2 v kazdem hobby marketu a vydrzi to alespon 10 let teploty - 20/+ 50 °C a bude to UV stale, tak se to asi prodavat bude.
    Jenom mas smulu, ze velka cast budov je v pamatkove chranenych zonach.

    SEJDA: tak na prefabrikovanejch vyrobkach mozna ano, ale kdyz to pretres v ramci zachrany klimatu a zadnou folii nelepis, tak se muzes s bilou dostat na 98% odrazivosti.

    Imho to nebude rozsahla investice. A pokud barva strechy domu neni vyslovne zakonem dana, tak je to jedna z levnych akci s hmatatelnym dopadem, co pro (lokalni) klima muze clovek udelat.

    'Whitest ever' paint reflects 98% of sunlight - BBC News
    https://www.bbc.com/news/science-environment-56749105

    Commercially available white paints reflect between 80% and 90% of sunlight, according to lead researcher Prof Xiulin Ruan from Purdue, in West Lafayette, Indiana. "It's a big deal, because every 1% of reflectance you get translates to 10 watts per metre squared less heat from the Sun," he explained.

    French President Emmanuel Macron to give exclusive interview to FRANCE 24
    https://www.france24.com/en/environment/20230622-emmanuel-macron-to-give-exclusive-interview-to-france-24

    Emmanuel Macron vyzval k novému mezinárodnímu zdanění, které by financovalo boj proti chudobě a klimatickým změnám.

    Francouzský prezident to řekl v rozhovoru s francouzskými veřejnoprávními médii k summitu pro Nový globální finanční pakt, který v pátek končí v Paříži.

    Podle něj se žádná země nesmí dostat do situace, kdy si bude muset vybrat "mezi chudobou, klimatem a biodiverzitou".

    SHEFIK: fakt nevim, kdyz vezmes kus plechu na strchu ma na zakladovce barvu a na te ochranou folii.
    Takze musis vzit odrazivost te folie, i to co pohlti a pak az vzit tu barvu. Jenom si treba vsimat, ze "bila" ma odrazivost jenom 50 % .. antracitova 70 %. No a cevena palena cihla asi taky nekde okolo tech 70 %, ale ta nema tu ochrannou folii.

    Satellite images show that Spain is in danger of drying out one of the main wetlands in Europe

    Satelitní snímky ukazují, že Španělsku hrozí vysušení jednoho z hlavních mokřadů v Evropě – !Argument
    https://casopisargument.cz/?p=50944

    Mokřady patří mezi biologicky nejrozmanitější, ale zároveň nejohroženější ekosystémy na Zemi. Jen za poslední století jich zmizelo přibližně 70 %, přičemž hlavní hrozbou je v mnoha případech nadměrné využívání vodních zdrojů.

    Cool Roof Technology Could Eliminate Billions Of Tons Of Carbon Dioxide - CleanTechnica
    https://cleantechnica.com/2023/06/22/cool-roof-technology-could-eliminate-billions-of-tons-of-carbon-dioxide/

    If all eligible urban flat roofs in the tropics and temperate regions were gradually converted to white (and sloped roofs to cool colors), they would offset the heating effect of the emission of roughly 24 gigatons of CO2, but one-time only,” said Art Rosenfeld, a physicist at Berkeley Lab. “However, if we assume that roofs have a service life of 20 years, we can think of an equivalent annual rate of 1.2 Gt per year. That offsets the emissions of roughly 300 million cars (about the cars in the world) for 20 years!”

    XCHAOS: ta boure nevznikla v atlantiku. Ale rekneme, ze od atlantiku se hnal vitr chladnejsi vzduch pres alpy, jak klesal k Mnichovu zacal tlacit horky vzduch a tam zacaly vznikat boure. Nez boure usla 70 km mela 4x vetsi prumer.
    Druhy smer, na Severu Nemecka zacal casove drive a nabral silu nad Francii, a pres Belgii se stocil k Berlinu.
    Tentokrat to sbiralo silu ne nad morem ale az nad pevninou.

    TADEAS:

    Overall, the team, comprised of scientists from Southampton, Sheffield and Bangor universities, as well as Rothamsted Research, looked at two lake ecosystems and two forests, using computer models with 70,000 adjustments of variables. They found that up to 15% of collapses occurred as a result of new stresses or extreme events, even while the primary stress was maintained at a constant level. The lesson they learned was that even if one part of an ecosystem is managed sustainably, new stresses such as global warming and extreme weather events could tip the balance towards a collapse.

    While the scope of the study was limited, the authors said the results showed the need for policymakers to act with more urgency.

    “Previous studies of ecological tipping points suggest significant social and economic costs from the second half of the 21st century onwards. Our findings suggest the potential for these costs to occur much sooner,” the co-author Prof John Dearing noted.

    ‘A green transition that leaves no one behind’: world leaders release open letter | Emmanuel Macron, Mia Mottley, Luiz Inácio Lula da Silva, Ursula von der Leyen, Charles Michel, Olaf Scholz, Fumio Ki...
    https://www.theguardian.com/environment/2023/jun/21/a-green-transition-that-leaves-no-one-behind-world-leaders-release-open-letter

    We, leaders of diverse economies from every corner of the world, are united in our determination to forge a new global consensus. We will use the Paris Summit for a New Global Financing Pact on June 22-23 as a decisive political moment to recover development gains lost in recent years and to accelerate progress towards the SDGs, including just transitions. We are clear on our strategy: development and climate commitments should be fulfilled and, in line with the Addis Ababa Action Agenda, we recognise that we need to leverage all sources of finance, including official development assistance, domestic resources and private investment.

    Delivering on that consensus should start with existing financial commitments. Collective climate-finance goals must be met in 2023. Our total global ambition of $100bn (£78bn) of voluntary contributions for countries most in need, through a rechannelling of special drawing rights or equivalent budget contributions, should also be reached.

    No country should have to wait years for debt relief. We need greater and more timely cooperation on debt, for both low- and middle-income countries. This starts with a swift conclusion of solutions for debt-distressed countries.

    A top priority is to continue ambitious reform of our system of multilateral development banks, building on the existing momentum. We are asking development banks to take responsible steps to do much more with existing resources and to increase financing capacity and private capital mobilisation, based on clear targets and strategies in terms of private finance contribution and domestic resource mobilisation. These financial resources are essential, but this reform is about far more than money. It should deliver a more effective operational model, based on a country-led approach. We also need our development banks to work together as an ecosystem, closely with other public agencies and streamlined vertical funds – and, where appropriate, with philanthropists, sovereign wealth funds, private finance and civil society – to deliver the greatest impact.

    Technology, skills, sustainability, and public and private investment will be at the core of our partnerships, to promote voluntary technology transfer, a free flow of scientific and technological talents, and contribute to an inclusive, open, fair and non-discriminatory economy. We will promote an agenda of sustainable and inclusive investment in developing and emerging economies, based on local economic value added and local transformation, such as fertiliser value chains. This comprehensive approach will require new metrics to update our accountability instruments.

    Public finance will remain essential to achieving our goals. We should start with strengthening our instruments (the International Development Association, the International Monetary Fund’s Poverty Reduction and Growth Trust and Resilience and Sustainability Trust, the International Fund for Agricultural Development, the Green Climate Fund, and other concessional windows of our banks, as well as the Global Shield against Climate Risks). But we acknowledge that meeting our development and climate goals, including the fight against hunger, poverty, and inequality; adapting to climate change; and averting, minimising and addressing loss and damage, will require new, innovative, and sustainable sources of finance, such as debt buy-backs, engagement from sectors that prosper thanks to globalisation, and more trusted carbon- and biodiversity-credit markets.
