    The new estimates of the “levelised cost” of electricity, published this week by the Department for Business, Energy and Industrial Strategy (BEIS), show that renewables are much cheaper than expected in the previous iteration of the report, published in 2016.

    The previously published version had, in turn, already trimmed the cost of wind and solar by up to 30%. As a result, electricity from onshore wind or solar could be supplied in 2025 at half the cost of gas-fired power, the new estimates suggest.

    Wind and solar are 30-50% cheaper than thought, admits UK government

    TUHO: komentar k fotce:

    "Bare soil around the trees?"

    "Correct observations. The photo shows quite a simple agroforestry system, with poplars and wheat, the tree lines most probably managed with herbicides. There is much convincing evidence to show that including poplars in a conventional wheat operations already has interesting benefits for the farmer and the land's ecology. Although relatively simple, creating this type of system can already represent quite complex changes for a farmer. We agree with you that from the picture it is not possible to say if this farm is regenerative or not. 'Regenerative' for us is actually an ideal to reach, but the path to get there definitely will not be perfect. We also believe there is much value in incremental improvement and changes of conventional operations, and we hope to document a lot of of farms in this type of situation. It is not easy to transition a farm towards regenerative practices in an economically viable way, and we applaud the farmer who has been brave enough to plant poplars with wheat.

    Unless we change course, the US agricultural system could collapse | Agriculture | The Guardian
    https://www.theguardian.com/commentisfree/2020/aug/26/us-farming-agriculture-food-supply-danger

    Interactions between Native Americans, plants, animals, microbes and climate left behind a majestic store of fertile topsoil that scientists call mollisol. Even today, the US midwest boasts the largest of four major mollisol stores on the planet. Mollisols develop over millennia yet can be squandered in decades. US colonial-settler agriculture transformed this ecological niche, a land mass 1.5 times the size of California, into a factory churning out just two crops – corn and soybeans.

    This kind of agriculture fouls water as a matter of course. Since corn and soybeans are planted in the spring and harvested in the fall, the vast majority of corn-belt farmland lies bare for the winter months, leaving the ground naked when storms hit. These deluges pummel bare topsoil and send it – and the agrochemicals and manure farmers apply to it – cascading off farms and into streams and creeks that flow into rivers, lakes and ultimately the Gulf of Mexico. But there’s another problem with subjecting the land to the same two crops every year: loss of the region’s precious black topsoil. According to research by the soil scientist Rick Cruse, Iowa – and much of the surrounding corn belt – is losing soil at a rate 16 times the pace of natural replenishment.

    Again, climate change is a driver. Today’s farmers encounter a weather regime radically different from that of their grandparents: more intense off-season storms, and thus ever-heavier pressure on the soil. If global greenhouse gases continue rising, the region faces a 40% increase in precipitation by the late 21st century, according to the Fourth National Climate Assessment. The soil that makes one of the globe’s most important growing regions so productive is vanishing before our eyes, degrading a crucial food production region at the very time when climate change and global population growth call for building resilience.

    Sucho navzdory dešťům neodeznělo. A bude se pravidelně vracet - Radek Kubala
    https://denikreferendum.cz/...nek/31579-sucho-navzdory-destum-neodeznelo-a-bude-se-pravidelne-vracet

    Dlouhá suchá období, jaké jsme zažili v posledních pěti letech, se podle vědeckých předpovědí budou v důsledku klimatické krize vracet stále častěji. Budou je však střídat vlhké roky provázené přívalovými dešti, které zvýší riziko povodní.


    Increased future occurrences of the exceptional 2018–2019 Central European drought under global warming
    https://www.nature.com/articles/s41598-020-68872-9

    Since the spring 2018, a large part of Europe has been in the midst of a record-setting drought. Using long-term observations, we demonstrate that the occurrence of the 2018–2019 (consecutive) summer drought is unprecedented in the last 250 years, and its combined impact on the growing season vegetation activities is stronger compared to the 2003 European drought. Using a suite of climate model simulation outputs, we underpin the role of anthropogenic warming on exacerbating the future risk of such a consecutive drought event. Under the highest Representative Concentration Pathway, (RCP 8.5), we notice a seven-fold increase in the occurrence of the consecutive droughts, with additional 40 (±5) million ha of cultivated areas being affected by such droughts, during the second half of the twenty-first century. The occurrence is significantly reduced under low and medium scenarios (RCP 2.6 and RCP 4.5), suggesting that an effective mitigation strategy could aid in reducing the risk of future consecutive droughts

      Co se stane, až bude v atmosféře dvakrát více CO2 oproti předindustriálním poměrům?
      Reakce globálních teplot na dvojnásobnou koncentraci CO2 se označuje jako klimatická citlivost (climate sensitivity) a po čtyřicet let se téměř neměnně udávala jako 1.5-4.5°C. Na konci července byly ale zveřejněny výsledky čtyřletého výzkumu, který se citlivostí klimatu zabýval a který nově ukazuje, že při dvojnásobném obsahu CO2 s největší pravděpodobností globální teploty stoupnou v rámci intervalu 2.3°C-3.9°C. Studie je velmi rozsáhlá (165 stran) a krom jiného ukazuje, že nárůst teplot pod 2°C má pravděpodobnost menší než 5%. Naopak je šance 6-18%, že by teploty mohly narůst o více jak 4.5°C.

      Tak hurikan Laura prichazi do USA.

      @capitalweather
      So far, Hurricane Laura has intensified at the fastest rate on record for any hurricane in the Gulf of Mexico (tied with Hurricane Karl in 2010). It went from Cat 1 to Cat 4 in 24 hrs.
      +
      Hurricane Laura is now forecast to be the strongest storm to ever make landfall along the western Louisiana and north Texas coast, with winds of 145 mph and storm surge of up to 20 feet. But what determines how much devastation a hurricane produces, and what hazards cause the most damage, varies from storm to storm.

      Meteorologists rate hurricanes by the intensity of the maximum sustained winds. It's fairly simple: the stronger the winds, the stronger the hurricane:

      Category 1: 74-95 mph
      Category 2: 96-110 mph
      Category 3: 111-129 mph
      Category 4: 130-156 mph
      Category 5: 157 mph or higher
      Any storm that's Category 3 or higher is considered a major hurricane. And the difference in damage between a run-of-the-mill hurricane and a major hurricane is, well, major. And major hurricanes all have a personality of their own, some heavy on wind damage and some heavy on water damage.


      Hurricane Laura packs the strongest winds the region has ever seen — but that's not the biggest threat - CBS News
