G-7 se hlásí k dekarbonizaci

NEW YORK – Jednání skupiny G-7 v hotelu Schloss Elmau v bavorských Alpách přineslo tento týden významný průlom v oblasti klimatické politiky. Zástupci sedmi největších vysokopříjmových ekonomik (Spojených států, Japonska, Německa, Velké Británie, Francie, Itálie a Kanady) dospěli k revolučnímu rozhodnutí dekarbonizovat během tohoto století své ekonomiky.

Poprvé v dějinách se velké bohaté ekonomiky shodly na potřebě ukončit svou závislost na fosilních palivech. Německá kancléřka Angela Merkelová, americký prezident Barack Obama i ostatní vedoucí představitelé skupiny G-7 vzali věci za správný konec a zaslouží si silné celosvětové uznání.

Historický průlom je zaznamenán v závěrečném komuniké. Státy G-7 nejprve zdůraznily význam udržení globálního oteplování pod úrovní 2° Celsia. To znamená, že průměrná teplota zeměkoule by se neměla odchýlit o více než 2°C od průměrné teploty, která na Zemi převažovala před vypuknutím průmyslové revoluce (zhruba před rokem 1800). Dosavadní globální oteplení však dosáhlo přibližně 0,9°C – takže jsme již téměř z poloviny vyčerpali prostor pod horní hranicí.

    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.
