Kyotos falsche Prioritäten

Wenn am 16. Februar das Kyoto-Protokoll in Kraft tritt, werden sich die Klimaschützer weltweit selbst gratulieren: Um Gutes zu tun, haben sie das Zustandekommen des teuersten Vertrages aller Zeiten gesichert. Es gelang ihnen, die globale Erwärmung zu einem zentralen moralischen Test unserer Zeit zu machen. Das war falsch.

Die globale Erwärmung ist ein Faktum und wird durch Kohlendioxidemissionen (CO2) hervorgerufen. Allerdings zeigen vorhandene Klimamodelle, dass wir wenig dagegen unternehmen können. Selbst wenn alle Länder dieser Welt (einschließlich der Vereinigten Staaten) das Kyoto-Protokoll annehmen und sich das ganze nächste Jahrhundert daran halten, wäre die dadurch hervorgerufene Veränderung kaum messbar sein und die Erwärmung würde sich um magere sechs Jahre auf das Jahr 2100 verschieben. Die dabei entstehenden Kosten betragen aber jährlich mindestens 150 Milliarden Dollar.

Die globale Erwärmung wird vor allem die Entwicklungsländer treffen, weil sie ärmer sind und daher weniger gut mit dem Klimawandel umgehen können. Allerdings erwartet man selbst in den pessimistischsten Prognosen der UNO, dass um das Jahr 2100 ein durchschnittlicher Einwohner in den Entwicklungsländern reicher sein wird als heute und daher bessere Möglichkeiten haben wird, mit den Veränderungen fertig zu werden.

    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.
