Erderwärmung: Wahr ist vielmehr das Gegenteil

NEW YORK – Wenn Politiker auf der ganzen Welt die Geschichte der globalen Erwärmung erzählen, stellen sie diese als die größte Herausforderung der Menschheit dar. Doch sie versprechen auch, in der Lage zu sein, diese Herausforderung kostengünstig zu bewältigen und die Welt gleichzeitig in vielfacher Hinsicht zu verbessern. Mittlerweile wissen wir, dass dies Unsinn ist.  

Politische Schwergewichte, von US-Außenminister John Kerry bis hin zu UNO-Generalsekretär Ban Ki-moon, bezeichnen den Klimawandel als „die größte Herausforderung unserer Generation.” Gelingt es uns nicht, ihr zu begegnen, so Kerry, werden die Kosten „katastrophal” ausfallen. Tatsächlich ist das die Standard-Behauptung von Politikern seit der Veröffentlichung des von der britischen Regierung im Jahr 2006 in Auftrag gegebenen so genannten Stern-Reports.

In diesem Bericht wird der Schaden aufgrund der globalen Erwärmung bekanntlich mit 5 bis 20 Prozent des BIP bewertet – ein erheblicher Einschnitt „der sich in ähnlichen Dimensionen bewegt wie die Auswirkungen der großen Kriege und der wirtschaftlichen Depression in der ersten Hälfte des 20. Jahrhunderts.“

    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 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.
