El rostro humano del cambio climático

Hace unas semanas en un periódico se describía un nuevo dispositivo inteligente. El aparato en cuestión extrae agua de la atmósfera y a cambio entrega un vaso de agua limpia y congelada. Es maravilloso lo que la tecnología puede ofrecerles a los ricos.

Sin embargo, no corren la misma suerte los millones de africanos que enfrentan la interrupción de las precipitaciones de las que dependen sus cultivos, su ganado y sus familias. En su caso, se puede esperar que el cambio climático traiga aparejadas tormentas más erráticas e inciertas, sin ninguna garantía de agua en el pozo, en el balde o en el campo.

El agua está en el corazón de la vida misma, ya sea para beber o lavar, para irrigar cultivos, para que abreve el ganado o para generar energía. Los que vivimos con un clima húmedo tendemos a maldecirlo, pero si enfrentáramos semana tras semana de sol ardiente sin ninguna perspectiva de nubes a la vista, estaríamos en serios problemas. Casi mil millones de personas en el planeta se las ingenian para vivir con una seria escasez de agua, y sus circunstancias muy probablemente empeoren con el cambio climático y la rápida urbanización.

  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.

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.
