Krankheiten durch globale Erwärmung

Heute bezweifeln nur noch wenige Wissenschaftler, dass sich die Erdatmosphäre erwärmt. Die meisten stimmen auch darin überein, dass sich der Grad der Erwärmung mit zunehmend zerstörerischen Folgen beschleunigen könnte. Schon Schulkinder können einige projizierte Ergebnisse vortragen: Die Ozeane erwärmen sich, die Gletscher schmelzen ab und lassen den Meeresspiegel ansteigen, so dass Salzwasser die Küstenniederungen überschwemmen; die landwirtschaftlichen Gebiete werden sich verlagern.

Doch sind die weniger vertrauten Wirkungen der globalen Erwärmung - namentlich, ernsthafte medizinische Störungen des Menschen - kaum weniger beunruhigend. Viele plagen uns bereits.

Unmittelbaren Folgen sind in erster Linie, dass die globale Erwärmung bis zum Jahr 2020 vermutlich zur Verdoppelung der Anzahl an Todesfällen aufgrund von Hitzewellen führen wird. Längere Hitzeperioden können für mehr Smog und die Ausbreitung derjenigen Allergene sorgen, welche die Symptome der Atemwegserkrankungen auslösen.

    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.
