    Elektrárny na zemní plyn nejsou vhodnou náhradou za uhlí, ukazují studie
    https://www.czechsight.cz/...arny-na-zemni-plyn-nejsou-vhodnou-nahradou-za-uhli-ukazuje-nova-studie/

    Elektrárny na zemní plyn tedy stále nabízejí úspory skleníkových plynů oproti elektrárnám na uhlí, tyto úspory jsou však v současnosti značně menší, než se předpokládalo. Evropská komise na tato zjištění reaguje novým nařízením, kdy od roku 2021 budou muset všichni dovozci zemního plynu do EU měřit a dokládat úniky zemního plynu při těžbě a budou mít povinnost tyto úniky snižovat na přijatelnou úroveň. Podle letošní zprávy International Energy Agency (IEA) je možné za použití současných technologií úniky zemního plynu na světě snížit až o 75 %.

    Green bonds fall short in biodiversity and sustainable land-use finance
    https://news.globallandscapesforum.org/...odiversity-and-sustainable-land-use-finance-says-research/

    How can Green Bonds catalyse investments in biodiversity and sustainable land-use projects? - Global Landscapes Forum
    https://www.globallandscapesforum.org/...estments-in-biodiversity-and-sustainable-land-use-projects/

    Despite their significance to life on Earth, biodiversity and sustainable land-use sectors attracted a mere three percent of the USD 257.7 billion raised through green bonds issued last year, says a new paper. Dominant sectors, including energy and transportation, absorbed almost 80 percent of green bond proceeds in the past three years.

    ...

    Overall, the green bond market is “rapidly scaling up” in value, according to the paper, but biodiversity and sustainable land use have been less appealing to investors because these can be under-developed in terms of information reporting, measurement and impact metrics. Yet the need is great: some 2 billion hectares of degraded land worldwide require restoration – a figure growing by about 12 million hectares annually, says the paper, citing figures from the World Resources Institutes (WRI) and the United Nations Convention to Combat Desertification (UNCCD). Forest and landscape restoration will require no less than USD 40 billion annually in each of the next 10 years to achieve the world’s commitments made through the Bonn Challenge, Initiative 20×20, AFR100 and the New York Declaration on Forests.

    ...

    There is a significant need for finance for the landscape approach and for biodiversity protection,” says Chahine. Landscape approaches balance competing land use demands in a way that is best for human well-being as well as the environment.

    “Green bonds might represent a good, innovative tool for these sectors, which hasn’t been receiving much attention within the broader green bond allocation,” he says.

    Furthermore, the European Union Sustainable Finance Taxonomy, now in development, could be a “game-changer” in terms of boosting interest in green bonds, by setting clear definitions of what economic activities and investments can be sold as genuinely “green” and that contribute to sustainable land use, biodiversity and other critical sectors, says Liagre.

    zpatky k plastum. ktery klima sice nezachrani, ale aspon se usetri naka ropa a skladkovani

    Můžeme se nějak zbavit záplavy jednorázových plastových obalů? Britský startup sází na překvapivý materiál - Ekolist.cz
    https://ekolist.cz/...avy-jednorazovych-plastovych-obalu-britsky-startup-sazi-na-prekvapivy-material

    Výhodou takových obalů je, že se po vyhození rozloží za 4-6 týdnů. V porovnání s normálním plastovým obalem, kterému to trvá několik set let, jde o zanedbatelný čas. Chaluhy jsou oproti jiným alternativám klasického plastu založených například na škrobu ekologičtější – na jejich pěstování není zapotřebí žádná půda a rostou velmi rychle.
    „Je to jeden ze zdrojů, kterého je opravdu hodně,“ říká spoluzakladatel společnosti Rodrigo Garcia. „Jedna z chaluh, kterou používáme, roste metr za den. Dokážete si představit něco takového? Přitom nepotřebujete žádné hnojivo. A navíc je to zdroj, který můžete používat opravdu dlouhodobě.“

    tento "navod" ma pobavil:

    "While it is clear that paper towels are not the best for those wanting to live with less waste, the good news is that paper towels are, for the most part, entirely optional. There are many viable alternatives to traditional paper towels that will still help you wipe, dry, and clean without all the negative impacts on the environment."

    TADEAS: tady jeste jeden katastrofictejsi. tyhle zmeny uz se musi promitnout do nejakejch civilizacne hmatatelmejch nasledku pristi rok

    https://www.discovermagazine.com/...warm-arctic-ocean-waters-are-delaying-freeze-up-and-pouring-heat

    As of Oct. 29th, sea ice extent was 1.3 million square miles less than the median extent for the years 1981 through 2010. That area of 'missing' ice is about a third again as large as all of the U.S. states east of the Mississippi River.

    ...

    In September, sea surface temperatures in the Laptev Sea off Siberia climbed higher than 5 degrees C, or 41 F. "That’s insanely warm for the Arctic Ocean, especially in that region, far away from any warmer inflow from the Atlantic or Pacific."

    ...

    Here, temperatures are forecast to be 10 degrees C, and even more, above normal. This, according to Meier, is a result of all the heat escaping from open Arctic waters into the atmosphere.

    Arctic sea ice loss could trigger huge levels of extra global warming | New Scientist
    https://www.newscientist.com/...ctic-sea-ice-loss-could-trigger-huge-levels-of-extra-global-warming/

    Global warming due to loss of large ice masses and Arctic summer sea ice
    https://www.nature.com/articles/s41467-020-18934-3

    Ricarda Winkelmann at the Potsdam Institute for Climate Impact Research in Germany and her colleagues modelled the impact of such feedbacks on global temperature rises if ice disappeared from mountain glaciers, the Greenland and West Antarctica ice sheets, and the Arctic in summer. They found that the loss of ice in all four places would, over centuries to millennia, contribute an extra 0.43°C of warming globally in the event of the world holding temperature rises to 1.5°C.

    ...

    Arctic feedbacks could bring warming on much shorter time scales. Summers in the region are expected to be ice-free before 2050. That means the Arctic alone could account for an extra 0.19°C of global warming around mid-century, on top of the 1.5°C.

    Prisoners of the Wrong Dilemma: Why Distributive Conflict, Not Collective Action, Characterizes the Politics of Climate Change
    https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3281045

    Thread by @mmildenberger on Thread Reader App – Thread Reader App
    https://threadreaderapp.com/thread/1321858069827973125.html

    Exciting news! @MichaelAklin and my new provocation is out in @GepJournal. We make a simple but far-reaching claim. **Empirically, climate politics is NOT primarily about collective action or free-riding**. A quick on why we've all been prisoners of the wrong dilemma

    For decades now, we've all assumed that free-riding is the binding constraint on global climate politics. Google "climate change" and "free-riding", and it generates 18000+ unique hits. Economists mince few words about this.

    The logic of free-riding seems powerful. No country can solve climate change alone. But acting is costly. So every country wants to free-ride off of other country's action. But then no-one has an incentive to act

    It's a fabulous idea. And you literally cannot overstate its influence. We've structured decades of climate negotiations on the assumption it is true. But is it? Do the empirics match this reality we've constructed? The surprising answer: not really!

    In our article, @MichaelAklin and I review the empirical evidence to evaluate whether it's consistent with our dominant collective-action flavored theory of climate politics. Shocking fact: we can't find ANY empirical evidence that shows it to be clearly correct.

    Instead, our review points to three things:

    1⃣National policy action occurs in the absence of institutions to manage free-riding. For example, US leaving Kyoto did not alter pace of reforms in other countries

    2⃣The public behaves like an unconditional climate cooperator! Most experiments and surveys do not find evidence that public support for action goes down in the presence of free-riding.

    3⃣National political actors also behave in a mostly unconditional fashion. For example, we revisit the Byrd-Hagel resolution and Bush's decision to reject Kyoto. We show that free-riding concerns were largely rhetorical, not substantive

    In short, we can't actually locate any empirical evidence to suggest that free-riding in practice constrains global climate politics, even though policymakers and academics have blindly assumed this fact for decades. Much more on this in paper (and more nuanced too!).

    So what explains climate politics if not free-riding concerns? We think economic conflict between policy winners and losers is the real binding constraint on global climate politics. It can account for existing empirical evidence more completely *and* parsimoniously.

    ...

    We've spent four decades assuming international institutions should primarily remedy free-riding. But maybe that's the wrong dilemma! Given the urgency of the threat, we can't risk our climate politics being a prisoner of the wrong theories. The stakes are too high.

    How the World Will Look if We Don't Address Climate Change | Time
    https://time.com/5824295/climate-change-future-possibilities/

    It is 2050. Beyond the emissions reductions registered in 2015, no further efforts were made to control emissions. We are heading for a world that will be more than 3 degrees warmer by 2100.

    ...

    You try not to think about the 2 billion people who live in the hottest parts of the world, where, for upward of 45 days per year, temperatures skyrocket to 140°F (60°C) —a point at which the human body cannot be outside for longer than about six hours because it loses the ability to cool itself down. Places such as central India are becoming increasingly challenging to inhabit. For a while people tried to carry on, but when you can’t work outside, when you can fall asleep only at 4 a.m. for a couple of hours because that’s the coolest part of the day, there’s not much you can do but leave. Mass migrations to less hot rural areas are beset by a host of refugee problems, civil unrest, and bloodshed over diminished water availability.

    Even in some parts of the United States, there are fiery conflicts over water, battles between the rich who are willing to pay for as much water as they want and everyone else demanding equal access to the life-enabling resource. The taps in nearly all public facilities are locked, and those in restrooms are coin-operated. At the federal level, Congress is in an uproar over water redistribution: states with less water demand what they see as their fair share from states that have more. Government leaders have been stymied on the issue for years, and with every passing month the Colorado River and the Rio Grande shrink further

    Food production swings wildly from month to month, season to season, depending on where you live. More people are starving than ever before. Climate zones have shifted, so some new areas have become available for agriculture (Alaska, the Arctic), while others have dried up (Mexico, California). Still others are unstable because of the extreme heat, never mind flooding, wildfire, and tornadoes.

    One thing hasn’t changed, though—if you have money, you have access. Global trade has slowed as countries such as China stop exporting and seek to hold on to their own resources. Disasters and wars rage, choking off trade routes. The tyranny of supply and demand is now unforgiving; because of its increasing scarcity, food can now be wildly expensive. Income inequality has never been this stark or this dangerous.

    As committed as nations are to keeping wealth and resources within their borders, they’re determined to keep people out. Most countries’ armies are now just highly militarized border patrols. Lockdown is the goal, but it hasn’t been a total success. Desperate people will always find a way.

    Ever since the equatorial belt started to become difficult to inhabit, an unending stream of migrants has been moving north from Central America toward Mexico and the United States. Others are moving south toward the tips of Chile and Argentina. The same scenes are playing out across Europe and Asia. Some countries have been better global Good Samaritans than others, but even they have now effectively shut their borders, their wallets, and their eyes.

    In the end, the story of their minds opening up came down to three key things: The first was they began to understand how the key landscape functions and the entire ecological system worked, and how all were indivisibly connected: that none could function in isolation. The second was they got out of the way to let nature repair, self-organize and regenerate these functions. And the third and vital factor was they had the humility to “listen to their land”, to then change but also continue to learn with that same openness.
