El huracán Sandy y el cambio climático

ATHENS (GEORGIA) – En las últimas semanas de la temporada norteamericana de huracanes, época en la que no se espera que una supertormenta cause daños generalizados en la costa oriental de los Estados Unidos, el huracán Sandy nos recuerda la sombría amenaza de los episodios climáticos extremos. Con la más baja presión central de la temporada de huracanes en 2012, Sandy puede haber causado daños de hasta 20.000 millones de dólares, por lo que ha resultado ser una de las supertormentas más costosas de la Historia.

Sandy se combinó con un sistema meteorológico que avanzaba desde el Este, lo que creó grandes dificultades a los pronosticadores y unas condiciones climáticas sin precedentes para la región. Una tormenta similar azotó a Nueva Inglaterra hace veinte años, pero Sandy ha sido peor, al ir acompañado de vientos huracanados, lluvias torrenciales y graves inundaciones de las costas en todo el populoso corredor nordoriental y atlántico central.

Naturalmente, algunos intentarán relacionar Sandy con el cambio climático. El mismo juicio apresurado se dio a raíz de los brotes de tornados en masa de los últimos años en los Estados Unidos, pese a que la bibliografía científica no respalda en gran medida esa conexión. Así, pues, desde la perspectiva del cambio climático, es mejor adoptar una opinión mesurada sobre Sandy para que las reacciones apresuradas no perjudiquen al crédito científico.

    Empowering China’s New Miracle Workers

    China’s success in the next five years will depend largely on how well the government manages the tensions underlying its complex agenda. In particular, China’s leaders will need to balance a muscular Communist Party, setting standards and protecting the public interest, with an empowered market, driving the economy into the future.

    The Sovereignty that Really Matters

    The preference of some countries to isolate themselves within their borders is anachronistic and self-defeating, but it would be a serious mistake for others, fearing contagion, to respond by imposing strict isolation. Even in states that have succumbed to reductionist discourses, much of the population has not.

    Resurrecting Creditor Adjustment

    When the Bretton Woods Agreement was hashed out in 1944, it was agreed that countries with current-account deficits should be able to limit temporarily purchases of goods from countries running surpluses. In the ensuing 73 years, the so-called "scarce-currency clause" has been largely forgotten; but it may be time to bring it back.

    Trump’s Republican Collaborators

    Republican leaders have a choice: they can either continue to collaborate with President Donald Trump, thereby courting disaster, or they can renounce him, finally putting their country’s democracy ahead of loyalty to their party tribe. They are hardly the first politicians to face such a decision.

    How Money Could Unblock the Brexit Talks

    With talks on the UK's withdrawal from the EU stalled, negotiators should shift to the temporary “transition” Prime Minister Theresa May officially requested last month. Above all, the negotiators should focus immediately on the British budget contributions that will be required to make an orderly transition possible.

    Is Vladimir Putin Losing His Grip?

    In recent decades, as President Vladimir Putin has entrenched his authority, Russia has seemed to be moving backward socially and economically. But while the Kremlin knows that it must reverse this trajectory, genuine reform would be incompatible with the kleptocratic character of Putin’s regime.

    Don’t Bank on Bankruptcy for Banks

    As a part of their efforts to roll back the 2010 Dodd-Frank Act, congressional Republicans have approved a measure that would have courts, rather than regulators, oversee megabank bankruptcies. It is now up to the Trump administration to decide if it wants to set the stage for a repeat of the Lehman Brothers collapse in 2008.
