La muerte de los sitios de Patrimonio Mundial

SAN FRANCISCO, CALIFORNIA – El cambio climático ha cobrado otra víctima más. Casi una cuarta parte del coral en la zona de Patrimonio Mundial de la Gran Barrera de Coral de Australia – uno de los ecosistemas del mundo más ricos y más complejos – ha muerto este año, en el peor blanqueamiento de coral de toda la historia conocida. Incluso en los confines más septentrionales de este arrecife, que se encuentran a una distancia lo suficientemente alejada de presiones humanas – por ejemplo de desarrollos costeros – como para poder preservar la salud del coral en gran medida, ha muerto un impactante 50% del coral.

Las temperaturas marinas por encima del promedio que desencadenaron este blanqueamiento se hicieron 175 veces más probables debido al cambio climático. A medida que el océano continúa absorbiendo calor de la atmósfera, es aún más factible que blanqueamientos de coral a gran escala, como el que diezmó a la Gran Barrera de Coral, sean aún más frecuentes y más devastadores – sin ni siquiera tener que citar otros fenómenos destructivos estimulados por dichas temperaturas en aumento.

El futuro de invaluables sitios de Patrimonio Mundial – y, en los hechos, el futuro de nuestro planeta – depende de la reducción inmediata de las emisiones de gases de efecto invernadero inductores del cambio climático. Sin embargo muchos de los gobiernos responsables de proteger estos lugares situados dentro de sus fronteras no sólo no toman medidas fuertes en cuanto al cambio climático, si no que están trabajando activamente en proyectos de energía sucia, como ser minas de carbón y plantas eléctricas a carbón.

    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.
