    Asi polovina světové populace se přinejmenším část roku potýká s nedostatkem pitné vody. A bude hůř, varovala zpráva Organizace spojených národů.

    „Blízký východ intenzivně pracuje na získávání sladké vody z té mořské. Pokud se tak ale činí ve velkém, nese to s sebou značná ekologická rizika,“ varuje klimatolog Miroslav Trnka z projektu Intersucho.

    Pít, či zavlažovat? Na nedostatek vody existují řešení, něco nás to ale bude stát, říká expert - VOXPOT

    Ani pandémia covidu či následná energetická kríza, zdá sa, nedokázali zásadnejšie (v podstate vôbec) ovplyvniť vývoj koncentrácií hlavných skleníkových plynov v zemskej atmosfére (oxid uhličitý & metán). Tie aj v roku 2022 pokračovali v rýchlom raste, v prípade CO2 o 2,13 ppm a metánu o 13,98 ppb (oxid dusný rastie už tretí rok za sebou rekordne rýchlo). Pri CO2 ide pritom o už 11. rok za sebou, kedy medziročný nárast neklesol pod 2 ppm (naposledy sa tak stalo v roku 2011; +1,68 ppm). Na globálnej úrovni tento rok oficiálne dosiahneme priemernú koncentráciu CO2 ---> 420 ppm! [Naposledy sme mali na Zemi takto vysokú koncentráciu CO2 približne pred 3 až 5 mil. rokmi.] Ako však ukazujú podklady z CAMS/ECMWF, úroveň CO2 na severnej pologuli už v súčasnosti výrazne presahuje hodnotu 424 ppm (regionálne až do 430 ppm) - samozrejme prihliadnuc k jeho ročnému cyklu. V prípade, že v tomto roku príde El Niňo, medziročný nárast CO2 môže atakovať hodnotu 3 ppm. Úhrnný radiačný ohrev zemskej atmosféry antr. skleníkovými plynmi je dnes o 45 % vyšší ako v roku 1990 a rýchlo rastie!

    Marec 2023 skončil "prekvapujúco" globálne ako druhý najteplejší marec v histórii (s odchýlkou +0,51 °C), a to za marcom 2016, kedy vrcholilo silné El Niňo (+0,63 °C). Prekvapujúco preto, že aj v priebehu tohtoročného marca sa ešte stále prejavoval ochladzujúci vplyv ustupujúcej La Nine. Na severnej pologuli sa v priebehu mesiaca vytvorili dve pozoruhodne rozsiahle teplotné anomálie, a to studená v priestore západnej polovice Sev. Ameriky (USA +Kanada), a oveľa rozsiahlejšia teplá anomália siahajúca od Mauretánie v záp. Afrike až po Kamčatku a Japonsko (rozsah takmer 15 000 km). Podľa toho, ako sa vyvíja v tomto roku tepelný obsah oceánov vo vrchných 100 m možno usudzovať na to, že ďalšie mesiace môžu byť ešte relatívne teplejšie.

Despite a severe housing shortage in France, new homes just aren’t worth the drain on water resources that construction, and eventual new residents, would cause, say nine communes in the south of the country. https://www.wired.co.uk/article/europe-drought-2023

    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.

    Partha Dasgupta is a Cambridge University economist who in 2021 prepared a more than 600-page report for the British government about the financial value of nature.

    Not your average bedtime reading.

    But believe us when we say his report, the culmination of decades of scholarship, is incredibly important. Or at least believe the United Nations, which awarded him the title Champion of the Earth for his work. Or King Charles III, who this year made Mr. Dasgupta a Knight Grand Cross of the Order of the British Empire — an extremely rare honor — for his services to economics and the natural environment.

    Mr. Dasgupta’s voluminous study is so important, that we decided to publish a short film about it, the Opinion video above

    Americká NOAA a austrálska BOM predpokladajú, že v tomto roku príde ďalšie El Niňo (už pomaly štartuje). Počiatočný stav je však taký, že globálne oceány sú teraz ešte teplejšie ako počas vrcholenia posledného El Niňa na začiatku roka 2016. Neuveriteľné! Tipujem, že ak by sa prognózy NOAA/BOM naplnili a El Niňo 2023/24 by bolo aspoň stredne silné, odchýlka globálnej teploty v roku 2024 bude aspoň +1,5 °C (február až apríl 2024 budú mať možno až +2,0 až +2,5 °C). A čo to bude znamenať? No minimálne to, že niektoré systémy sa priblížia k "tipping pointom" svojej stability (napr. koralové útesy). Inými slovami povedané, čakajú nás tri veľmi turbulentné roky, kedy nebudeme ani stíhať zapisovať "klimatické" extrémy a uvidíme veci, o ktorých sme rozprávali len v tých najviac pesimistických scenároch.

    Scott Duncan - We just observed Earth's 2nd warmest March... | Facebook
    https://m.facebook.com/story.php?story_fbid=937871050928558&id=100041170155733

    We just observed Earth's 2nd warmest March on record. Some of the strongest hotspots with many records were found in Argentina and across a vast area reaching from NW Africa all the way through Asia.

    It wasn't warm for everyone though. Swipe through...

    Intense cold lingered over large portions of North America. Some very striking cold anomalies and particularly stormy weather for the west coast (delivering much needed rain and mountain snow). It was also cold in Iceland & Fennoscandia. Very notable intensity to the cold especially late in the month.

    But the area of significant warmth from Morocco to Kamchatka really is impressive. Large portions of Central Asia averaged more than 5°C warmer than the 1981-2010 baseline.

    A look at the Southern Hemisphere... Relentless heatwaves in South America with the Bullseye in Argentina. Long-standing monthly records were broken.

    Also, no more La Niña...
