Las enfermedades provocadas por el calentamiento de la Tierra

Hoy pocos científicos dudan que la atmósfera de la Tierra se está calentando. La mayoría convienen en que ese proceso se está acelerando y sus consecuencias podrían llegar a ser cada vez más perturbadoras. Incluso los colegiales pueden recitar algunos resultados previstos: los océanos se calentarán y los glaciares se derretirán, con lo que aumentarán los niveles del mar y el agua salada invadirá las zonas costeras bajas. Las regiones idóneas para la agricultura cambiarán.

Pero los efectos menos conocidos del calentamiento de la Tierra -a saber, los trastornos médicos graves para los seres humanos- no son menos preocupantes. Muchos de ellos están ya entre nosotros.

El más directo es el de que, según las previsiones, en 2020 el calentamiento de la Tierra habrá duplicado el número de fallecimientos relacionados con las olas de calor. El calor prolongado puede aumentar la niebla tóxica y la dispersión de alérgenos, lo que causará síntomas respiratorios.

    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.

    Rage Against the Elites

    • Taken together, they help us to understand what that moment is and how it arrived, while reminding us that history is contingent, not inevitable

    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.
