Vuelta a la razón

COPENHAGUE – El sentido común fue una de las cosas que primero se perdió en la acalorada batalla acerca de la realidad del calentamiento global causado por el hombre. Por cerca de 20 años, un grupo de activistas argumentó -ante evidencias cada vez más claras- que el calentamiento global era un invento. Mientras tanto, sus oponentes exageraron el impacto probable del fenómeno y, en consecuencia, se obsesionaron dogmáticamente con que la reducción drástica y de corto plazo de las emisiones de carbono era la única solución, a pesar de las abrumadoras evidencias de que esto sería enormemente costoso e ineficaz.

Esta torpe guerra entre científicos, caracterizada por inmaduros epítetos lanzados por unos a los otros, tácticas innobles e intransigencia de ambas partes, no sólo dejó al público general confuso y asustado, sino que socavó los esfuerzos de las organizaciones más importantes que buscan determinar las bases científicas del cambio climático. Casi inevitablemente, en las cumbres internacionales de Kioto a Copenhague los gobiernos no lograron acordar ninguna medida de peso sobre el asunto.

Afortunadamente, parece estar surgiendo un grupo de científicos, economistas y políticos que representa un enfoque más sensato al respecto.

    The Brexit Surrender

  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.
