    1. 250. Tackling ‘Big History’ feat. Ian Morris<br /> unSILOed Podcast with Greg LaBlanc

      • Most of human history and evolution is about energy capture.
      • Investing 80x energy into land to get 4x output from it has been transformational for modern farmers. (Turning oil into bread.)
      • Marshall Sahlins - synopsis: agriculture is a really bad idea.
      • Morris Theorem: human history is driven by lazy, greedy people.
      • "Fossil fuel values" (00:39:00)
      • fairness is a fundamental human value; justice is dramatically different across time and space (00:45:08)
      • Morris' "5 Horsemen of the Apocalypse" (the five problems humans encounter when they reach the limits of energy extraction): massive movements of people (mobility); epidemics; climate change; war; governmental collapses;
      • The price of overhunting for one person versus the price for the collective. How do we solve these collective problems (particularly for lazy, greedy humans)? (00:52:35)
      • Regional failures were the general pattern before; now failures are a global scale problem.

    1. Der Artikel diskutiert die Notwendigkeit von Carbon Dioxide Removal (CDR) zur Erreichung der Klimaneutralität. Aktuell werden weltweit etwa 2,2 Gigatonnen CO₂ pro Jahr entnommen, hauptsächlich durch Aufforstung. Neue Technologien wie Direct Air Capture (DAC) sind noch wenig verbreitet, machen nur ein Promille aus. Um die Pariser Klimaziele zu erreichen, müsste die CO₂-Entnahme bis 2050 auf 7 bis 9 Gigatonnen pro Jahr steigen. Deutschland plant, bis 2045 klimaneutral zu werden, und benötigt dafür eine nationale CDR-Strategie. Derzeit kostet die Entnahme einer Tonne CO₂ mit neuen Methoden 100 Mal mehr als die Vermeidung einer Tonne Emissionen. 27 Staaten und die EU haben Vorschläge zur Ausweitung von CDR bis 2050 gemacht.

      I'm not sure exactly where this would fit in, but some way to reporting total service hours (per week or other time period) would be useful, esp as we start gauging traffic, volume, usage against number of service hours. In our reporting for the Univ of California, we have to report on services hours for all public service points.

      Likewise, it may be helpful to have a standard way to report staffing levels re: coverage of public service points? or in department? or who work on public services?
