Den pro planetární spravedlnost

PRINCETON – To, co nedbalou produkcí skleníkových plynů způsobujeme naší planetě, dětem a vnoučatům a chudým lidem, patří k největším mravním špatnostem našeho věku. 24. října se proti této nespravedlnosti můžete postavit.

24. říjen je Den 350. Tento název pochází od počtu částic na milion (ppm) oxidu uhličitého v atmosféře, který bychom podle Jima Hansena, zřejmě nejpřednějšího světového klimatologa, neměli překročit, máme-li se vyvarovat potenciálně katastrofální změně klimatu. Mírou závažnosti našeho problému je, že už teď CO2 dosahuje 386 ppm a každoročně jej o dvě ppm přibývá.

Nutnost snižovat skleníkové plyny začala být čím dál jasnější, když se opakovaně ukázalo, že prognózy globálního oteplování – pranýřované jako „poplašné zprávy“, když se před pouhými několika lety objevily – jsou příliš konzervativní. Blížíme se do bodu, za nímž už nebude návratu, neboť začnou působit zacyklené zpětné vazby a budou planetu nadále ohřívat, ať děláme, co děláme.

    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.
