El verano interminable de las ciudades asiáticas

POTSDAM/MANILA – Tras meses de temperaturas abrasadoras, comenzó la estación de monzones en Asia. Pero el calor extremo regresará, y las ciudades enfrentarán condiciones particularmente brutales. Las áreas urbanas de Asia ya experimentan el doble de días calurosos que las rurales, y es posible que en 2100 la diferencia sea de diez a uno. A partir de entonces, no habrá modo de revertir la tendencia.

La primera evaluación detallada del riesgo climático para Asia, realizada por el Banco Asiático de Desarrollo y el Instituto de Investigación del Impacto Climático en Potsdam, deja en claro que en la lucha contra el cambio climático, las ciudades asiáticas están en primera línea. De hecho, en las áreas urbanas se cruzan muchas de las consecuencias del calentamiento del planeta, por ejemplo, fenómenos meteorológicos más extremos, aumento del nivel del mar, migración ambiental y agravamiento de tensiones sociales.

Esto se aplica especialmente a Asia, donde las ciudades albergan a más de la mitad de la población y casi el 80% de la producción económica. Es posible que en 2050 la población urbana de Asia haya crecido a casi el doble, a tres mil millones de personas. De no tomarse medidas adicionales para mitigar el cambio climático, las ciudades de la región tal vez contribuirán más de la mitad del aumento de la emisión mundial de gases de efecto invernadero en los próximos veinte años.

  3. Murdoch's Last Stand?

    Rupert Murdoch’s sale of 21st Century Fox’s entertainment assets to Disney for $66 billion may mark the end of the media mogul’s career, which will long be remembered for its corrosive effect on democratic discourse on both sides of the Atlantic. 

    From enabling the rise of Donald Trump to hacking the telephone of a murdered British schoolgirl, Murdoch’s media empire has staked its success on stoking populist rage.

    The Dangerous Delusion of Price Stability

    Since the hyperinflation of the 1970s, which central banks were right to combat by whatever means necessary, maintaining positive but low inflation has become a monetary-policy obsession. But, because the world economy has changed dramatically since then, central bankers have started to miss the monetary-policy forest for the trees.

    Jeffrey Frankel, a professor at Harvard University’s Kennedy School of Government and a former member of President Bill Clinton’s Council of Economic Advisers, outlines the five criteria he uses to judge the efficacy of tax reform efforts. And in his view, the US Republicans’ most recent offering fails miserably.
