Washington's shift from liberal‑values diplomacy toward a Christian‑nationalist framework is weakening the traditional basis of the U.S.-Japan alliance and turning religious freedom into a selective diplomatic tool. https://www.japantimes.co.jp/commentary/2026/07/16/japan/us-japan-relations-next/?utm_medium=Social&utm_source=mastodon #commentary #japan #us #coldwar #sovietunion #donaldtrump #christianity #china #usjapanrelations #dei #chinesecommunistparty #jinmingri #xijinping #xinjiang #tibet #falungong #shinzoabe

Jean-Jacques Annaud – „Sieben Jahre in Tibet“ (1997)Anlässlich des Geburtstages von Tenzin Gyatso, des 14. Dalai Lama (* 06.07.1935) erinnert sich auch die ZDF-Spielfilmredaktion wieder an Tibet. Doch das Land wird hier nur dargestellt als entgrenzte Projektionsfläche für spirituelle Sehnsüchte und als Bühne für die persönliche Erweckungsgeschichten eines Nazis. Jean-Jacques Annaud bedient diese Logik mit all der grandiosen Kraft des Kinos – und scheitert gerade deshalb daran, Tibet als politischen Ort ernst zu nehmen. (ZDF, Wh.)

Davanti alla sede dell’ONU, Lobsang Palden è morto dopo essersi dato fuoco per richiamare l’attenzione sul Tibet: dal 2009 oltre 170 tibetani hanno compiuto gesti simili.
La repressione cinese d'altronde non si ferma ai confini: sorveglianza della diaspora e presunte stazioni di polizia non dichiarate mostrano una repressione transnazionale che riguarda anche l’Europa.
L’UE deve proteggere tibetani e uiguri, chiedere accesso indipendente a Tibet e Xinjiang e vincolare i rapporti con Pechino ai diritti umani.#Tibet #Uiguri #DirittiUmani #Xinjiang #RepressioneCinese #EuropaFederale #Volt #VoltItalia #VoltEuropa

If some channel you follow suddenly started posting about how great life in Tibet or Xinjiang is under Chinese rule, you can now be sure they are a part of the CCP's propaganda machine, or at the very least, a useful idiot.

another reminder that CCP is a threat for democratic countries, engages at cultural genocide, and they will stop at nothing. and dependency on its manufacturing, rare earth minerals etc. for Europe is tenfold bigger than on russian oil & gas.
the sooner people realise it, the better.

Rock Weathering Can Counteract River CO2 Emissions Induced By Permafrost Thaw

“[The researchers] measured carbon emissions and water chemistry in 50 headwater rivers draining 780,000 km² of the Tibetan Plateau.
The rivers flow in landscapes underlain by continuous permafrost and landscapes in which the permafrost has retreated since the last glacial maximum. They collect[ed] organic carbon from soils and dissolved inorganic carbon that is fixed by rock-weathering.
Where the permafrost cover is continuous, rivers emit CO2 from degrading (permafrost) soil carbon. Weathering reactions in these catchments are relatively slow.
In landscapes with (almost) no permafrost, carbon fluxes from weathering are faster than CO2 emissions from rivers.
Thus, as permafrost landscapes transition to landscapes without permafrost cover, chemical weathering reactions may play an ever more important role in riverine carbon cycling.
Interestingly, weathering can affect the carbon cycle in different ways. Where sulfide minerals are present, weathering reactions can emit CO2. Where silicate minerals dominate, weathering draws down CO2 from the atmosphere…”

“Climate-induced permafrost thaw unlocks large stores of organic carbon that are mineralized and emitted as carbon dioxide (CO2) from rivers to the atmosphere. Concurrently, warming and permafrost thaw can increase mineral weathering rates, thus affecting the release and sequestration of inorganic carbon. Yet how these biological and geological carbon cycles interact and jointly affect CO2 dynamics (emission compared with drawdown) in permafrost rivers remains unknown. Here [they] combine[d] CO2 emissions, organic and inorganic solute concentrations, dual carbon isotopes (δ13C–Δ14C) and geochemical modelling to infer how permafrost thaw may affect river biogeochemistry over decades to centuries across the Qinghai–Tibet Plateau. Leveraging a gradient of thermal permafrost degradation, we find that river CO2 emissions decline, whereas solute fluxes from rock weathering increase with decreasing permafrost cover. Across this region, net CO2 drawdown fluxes from rock weathering are about 35% of river CO2 emissions, varying from around 15% in catchments with continuous permafrost to more than 100% in catchments with discontinuous or isolated permafrost. Thus, carbon fluxes from chemical weathering may become increasingly important with ongoing permafrost thaw, potentially even outpacing river CO2 emissions. [Their] findings disentangle the interplay between biological and geological carbon fluxes that are important for the cryosphere and the global carbon cycle…”

La Chine construit le plus grand barrage du monde dans une région sismique du Tibet
Pour réduire sa dépendance aux énergies fossiles, la Chine s’apprête à construire le plus grand barrage hydroélectrique du monde. Un projet titanesque, qui n'est pas sans risque pour les populations locales et les pays voisins.
Les motivations chinoises sont multiples: lutter contre la pénurie d'eau dans ces régions industrialisées et densément peuplées, soutenir l'essor de la demande énergétique et s'affranchir davantage des énergies fossiles. Pékin a ainsi choisi de miser sur l’hydroélectricité. Le barrage de Motuo s’inscrit également dans une stratégie géopolitique plus large, celle de renforcer le contrôle chinois sur les sources d’eau dont dépendent les pays voisins.
La Chine est le plus gros constructeur mondial de barrages.

Warming unlocks ancient carbon in Tibetan permafrost, triggering climate tipping point
The results revealed a clear and troubling pattern across all warming levels. Even under low to moderate warming, #carbon losses through respiration outpaced photosynthetic carbon gains by 1–16-fold.
Warming by +1°C, +2°C, and +4°C increased annual net #CO2 release by 44%, 80%, and 176%, respectively, and the site was a net carbon source before any experimental warming began.
"When warming reaches around 2–4°C, the system changes fundamentally," Ding told Phys.org. "Plants begin to reach their thermal and water-stress limits, so photosynthesis declines. At the same time, thaw penetrates deeper into the #soil, exposing old #permafrost carbon that has been frozen and protected for hundreds to thousands of years. Once thawed, microbes can decompose it and release it as CO2."
