Las emisiones cero son un imperativo

DAVOS – Nuestro planeta se está calentando de manera peligrosa. Y, tal como el informe 2013 del Panel Intergubernamental sobre el Cambio Climático deja en claro, es muy probable que las culpables de dicho calentamiento sean nuestras emisiones de dióxido de carbono durante el último medio siglo. Si deseamos evitar la catástrofe, necesitamos un enfoque más robusto con relación al calentamiento global. A diferencia de la reciente crisis financiera, en el caso del clima de la tierra no existe la opción de implementar un plan de rescate.

Hace tres años, en la reunión sobre el cambio climático de la 16 Conferencia de las Partes de las Naciones Unidas en Cancún, los países se comprometieron a reducir sus emisiones hasta el año 2020, hasta que las mismas se reduzcan a un punto en el que se evite que la temperatura promedio mundial aumente en más de 2° C, sobre los niveles preindustriales. Sin embargo, las estimaciones de la ONU muestran que las tendencias actuales conducirían a que el mundo solamente logre avanzar entre un 25 al 50% del camino hacia el logro de dicho objetivo.

Es por ello que convoco a todos los gobiernos para que ellos sean más ambiciosos – para que los países aspiren a lograr emisiones netas cero, con relación a los combustibles fósiles, hasta finales de la segunda mitad de este siglo. Nada que sea menor a una transformación total de la economía de la energía será suficiente.

    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.
