    1. Das Wasserversorgungssystem des Iran ist vor allem wegen der Entnahme des Wassers für Landwirtschaft und Industrie komplett und irreparabel zusammengebrochen. Dabei ist das Land immer mehr Hitzewellen ausgesetzt, bei denen in einigen Gebieten Temperaturen von über 55° C erreicht werden. Durch die Verarmung in den letzten Jahren ist die Bevölkerung in den betroffenen Provinzen besonders verwundbar. Reportage der New York Times. https://www.nytimes.com/2023/07/23/world/middleeast/iran-heat-water.htmltopic

    1. Afghanistan ist zur Zeit von Starkregen und Flutwellen betroffen und leidet zugleich unter Hitzewellen. Die Überflutungen sind das Ergebnis der Ausdehnung der Monsungebiete nach Nordwesten. Die Temperaturen haben in Afghanistan seit 1950 um 1,8 Grad zugenommen. Unter anderem drei aufeinanderfolgende Dürren haben den Grundwasserspiegel in Afghanistan in fünf Jahren um 11 m gesenkt. Umfassender Bericht der taz über das von der globalen Erhitzung besonders betroffene Land.

    1. Eine neue Studie beschäftigt sich mit der zunehmenden Frequenz der Aufeinanderfolge extremer Trockenheit und extremer Niederschläge in Pakistan und in vielen afrikanischen Ländern.

    1. Zwei neue Studien aufgrund einer genaueren Modellierung der Zusammenhänge von Erhitzung und Niederschlagen: Es lässt sich besser voraussagen, wie höhere Temperaturen die Bildung von Wolkenclustern in den Tropen und damit Starkregenereignisse fördern. Außerdem lässt sich erfassen, wie durch die Verbrennung von fossilen Brennstoffen festgesetzten Aerosole bisher die Niederschlagsmenge in den USA reduziert und damit einen Effekt der globalen Erhitzung verdeckt haben.

    1. Rational optimism regarding our future, then, is only possible to the extent we can find prior evolutionary steps which are plausibly more improbable than they look. Conversely, without such findings we must consider the possibility that we have yet to pass through a substantial part of the Great Filter. If so, then our prospects are bleak, but knowing this fact may at least help us improve our chances. For example, if our prospects are likely bleak we should search out and take especially seriously any plausible scenarios, such as nuclear war or ecological collapse, which might lead to our future inability to explode across the universe. A long list of such scenarios for concern can be found in [Leslie 96]. Our main data point, the Great Silence, would be telling us that at least one of these scenarios is much more probable than it otherwise looks. With such a warning in hand, we might, for example, take extra care to protect our ecosystems, perhaps even at substantial expense to our economic growth rate. We might be even especially cautious regarding the possibility of world-destroying physics experiments. And we might place a much higher priority on projects like Biosphere 2, which may allow some part of humanity to survive a great disaster.

        • risks go up disproportionately with every 0.1 deg C of warming. There is no longer a business-as-usual option now. We CANNOT ACT INCREMENTALLY NOW.
      • 00:36:00

        • we calculate a need of a speed up of a factor of 7 to shut down greenhouse gas emissions and that is done through positive tipping points.

      -00:37:00 - We have accelerating positive feedbacks and if we coordinate policy changes with consumer behavior change and business behavior change to reinforce these positive feedbacks, we can help accelerate change in the other sectors of the global economy responsible for all the other emissions

    1. four different types of initiators of new community projectsbased in neighbourhoods:local government,governmental organisations,non-governmental organisations or activists andexisting communities.
      • for: types of initiators of community projects, SONEC - initiators of community projects, question - frameworks for community projects, suggestion - collaboration with My Climate Risk, suggestion - collaboration with U of Hawaii, suggestion - collaboration with ICICLE, suggestion - collaboration with earth commission, suggestion - collaboration with DEAL

      • question: frameworks for community projects

        • If our interest is to attempt to create a global collective action campaign to address our existential polycrisis, which includes the climate crisis, then how do we mobilize at the community level in a meaningful way?

        • I suggest that this must be a cosmolocal effort. Why? Knowledge sharing across all the communities will accelerate the transition of any participating local community.

        • This means that we cannot rely on citizens living in small communities to construct an effective coordination framework for rapid de-escalation of the polycrisis. The capacity does not exist within small communities to build such a complex system. The system can be more effectively built before the collective action campaign is started by a virtual community of experts and ready for trial with pilot communities.
        • To meet this enormous challenge, it cannot be done in an adhoc way. At this point in time, many people in many communities all around the globe know of the existential crisis we face, but if we look at the annual carbon emissions, none of the existing community efforts has made a difference in their continuing escalation.
        • The knowledge required to synchronize millions of communities to have a unified wartime-scale collective action mobilization to reach decarbonization goals that the mainstream approach has not even made a dent in will be a complex problem.
        • In other words, what is proposed is a partnership.
        • Since we are faced with global commons problems that pose existential threats if not mitigated in 5 to 8 years, the scope of the problem is enormous.
        • Super wicked problems require unprecedented levels of collaboration at every level.
        • The downscaling of global planetary boundaries and doughnut economics seems the most logical way to think global, act local.
        • Building such a collaboration system requires expert knowledge. Once built, however, it requires testing in pilot communities. This is where a partnership can take place

    1. The earlier a serious Manhattan-like project to develop nanotechnology is initiated, the longer it will take to complete, because the earlier you start, the lower the foundation from which you begin. The actual project will then run for longer, and that will then mean more time for preparation: serious preparation only starts when the project starts, and the sooner the project starts, the longer it will take, so the longer the preparation time will be. And that suggests that we should push as hard as we can to get this product launched immediately, to maximize time for preparation.

      for sure?
