Historia de dos tratados

PRAGA – El mundo ha vuelto a fracasar en su intento de alcanzar acuerdo sólido alguno sobre el clima, esta vez en las negociaciones que concluyeron recientemente en Doha. El lector puede no haberlo advertido, porque, en contraste muy marcado con los años anteriores, la mayoría de los medios de comunicación, como reflejo de un desinterés cada vez mayor del público, se han limitado a pasar por alto dichas negociaciones.

La reunión de Doha era la continuación de veinte años de negociaciones fracasadas sobre el clima, desde la Cumbre de la Tierra inicial, celebrada en Río en 1992. Allí, los países prometieron reducir en el año 2000 las emisiones de gases que provocan el efecto de invernadero a los niveles de 1990; los países de la OCDE se alejaron del objetivo en casi un nueve por ciento. El Protocolo de Kyoto de 1998 ha fracaso casi enteramente y el empeño de salvar el mundo en Copenhague en 2009 se hundió estrepitosamente.

Hasta ahora, las emisiones del mundo no han cesado de aumentar –y a un ritmo acelerado–, pues las de 2011 fueron un 50 por ciento mayores que en 1990. Los veinte últimos años de negociaciones mundiales sobre el clima han reducido ese aumento en tan sólo medio punto porcentual.

    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.
