Klimawandel und Wassersicherheit

Der internationale Klimaausschuss IPCC hat jüngst alarmierende Daten über die Auswirkungen der globalen Erwärmung in manchen der ärmsten Regionen der Welt veröffentlicht. Man rechnet, dass um das Jahr 2100 eine bis drei Milliarden Menschen weltweit unter Wasserknappheit leiden werden. Die globale Erwärmung bewirkt eine erhöhte Verdunstung und einen krassen Rückgang der Regenmenge – bis zu 20 % im Nahen Osten und Nordafrika – wodurch die pro Person zur Verfügung stehende Wassermenge in diesen Regionen bis Mitte dieses Jahrhunderts möglicherweise um die Hälfte zurückgehen wird.

Diese plötzliche Knappheit eines Elements, dessen symbolischer und spiritueller Stellenwert seiner zentralen Bedeutung für die Menschheit entspricht, wird zu Belastungen führen und Konflikte weltweit verschärfen. Afrika, der Nahe Osten und Zentralasien werden das als erste zu spüren bekommen. Die Auswirken werden allerdings globales Ausmaß erreichen.

Diese düsteren Aussichten sind jedoch weder eine Ausrede für Gleichgültigkeit noch ein Grund für Pessimismus. Konflikte sind vielleicht unausweichlich, Kriege jedoch nicht. Unsere Möglichkeiten, „Wasserkriege“ zu verhindern, werden von unserer Fähigkeit abhängen, Spannungen frühzeitig zu erkennen sowie technische und institutionelle Lösungen zu finden, um diese Konflikte zu bewältigen. Die gute Nachricht ist, dass es diese Lösungen gibt und sie ihre Wirksamkeit jeden Tag unter Beweis stellen.

    Populist Plutocracy and the Future of America

    • In the first year of his presidency, Donald Trump has consistently sold out the blue-collar, socially conservative whites who brought him to power, while pursuing policies to enrich his fellow plutocrats. 

    • Sooner or later, Trump's core supporters will wake up to this fact, so it is worth asking how far he might go to keep them on his side.

    The Man Who Didn’t Save the World

    A Saudi prince has been revealed to be the buyer of Leonardo da Vinci's "Salvator Mundi," for which he spent $450.3 million. Had he given the money to the poor, as the subject of the painting instructed another rich man, he could have restored eyesight to nine million people, or enabled 13 million families to grow 50% more food.

    Two Myths About Automation

    While many people believe that technological progress and job destruction are accelerating dramatically, there is no evidence of either trend. In reality, total factor productivity, the best summary measure of the pace of technical change, has been stagnating since 2005 in the US and across the advanced-country world.

    The Hungarian Government’s Failed Campaign of Lies

    The Hungarian government has released the results of its "national consultation" on what it calls the "Soros Plan" to flood the country with Muslim migrants and refugees. But no such plan exists, only a taxpayer-funded propaganda campaign to help a corrupt administration deflect attention from its failure to fulfill Hungarians’ aspirations.
