Hablar con sensatez del calentamiento planetario

LONDRES – En febrero, catorce destacados científicos, economistas y expertos en políticas del clima se reunieron para hablar sobre cómo abordar el calentamiento planetario. Esta semana, la London School of Economics y la Universidad de Oxford van a publicar sus conclusiones. Vale la pena examinarlas.

Reunió al grupo Gwyn Prins, reputado experto en política de seguridad y relaciones internacionales que dirige el Programa Mackinder de la LSE para el estudio de las tendencias a lo largo de períodos muy largos. Entre los participantes, figuraron el científico del clima Mike Hulme, de la Universidad de East Anglia, el experto en política climática Roger Pielke Jr., de la Universidad de Colorado, y el economista del clima Christopher Green, de la Universidad McGill.

El informe del grupo, “el documento Hartwell”, expone a grandes rasgos una nueva orientación para la política del clima después del rotundo fracaso de los intentos de negociar un acuerdo mundial sobre el clima el año pasado. Los autores observan que, después de dieciocho años de formularse el “planteamiento del protocolo de Kyoto” de la política internacional sobre el clima, no se ha logrado en el mundo real reducción discernible alguna de las emisiones de los gases que provocan el efecto de invernadero.

    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.
