Encender una luz sobre el cambio climático

NUEVA YORK – Una bombilla eléctrica puede no ser lo primero que se nos ocurra al pensar en tecnología revolucionaria. Sin embargo, en el mundo actual la ciencia y una política inteligente tienen posibilidades de transformar un objeto doméstico corriente en una innovación revolucionaria.

Recientemente, visité un proyecto ambicioso para fomentar el ahorro de energía para iluminación en China. Mediante el abandono progresivo de las bombillas eléctricas incandescentes y la introducción de una nueva generación de medios de iluminación, China espera reducir en un ocho por ciento el consumo nacional de energía, lo que puede tener una profunda repercusión mundial. Piénsese en lo siguiente: la iluminación representa el 19 por ciento del consumo mundial de energía. Los científicos dicen que podemos reducirla en un tercio o más simplemente cambiando las bombillas.

Un avance semejante pone de relieve una de las muchas formas en que las personas y las empresas corrientes pueden reducir el uso de la energía y reducir los gases que producen el efecto de invernadero. Subraya el papel esencial que los Estados pueden –y deben– desempeñar en el fomento de la economía verde y pone de manifiesto el deber especial del Gobierno de China de encabezar la lucha mundial contra el cambio climático.

    The Brexit Surrender

    European Union leaders meeting in Brussels have given the go-ahead to talks with Britain on post-Brexit trade relations.

    • Congressional Republicans are finalizing a tax-reform package that will reshape the business environment by lowering the corporate-tax rate and overhauling deductions. 

    • But will the plan's far-reaching changes provide the boost to investment and growth that its backers promise?

  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.

  5. Harvard’s Jeffrey Frankel Measures the GOP’s Tax Plan

    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.

    The Holy Grail of Genetic Engineering

    CRISPR-Cas – a gene-editing technique that is far more precise and efficient than any that has come before it – is poised to change the world. But ensuring that those changes are positive – helping to fight tumors and mosquito-borne illnesses, for example – will require scientists to apply the utmost caution.
