La falsedad del ataque a la ciencia del clima

NUEVA YORK – En las semanas anteriores y posteriores a la conferencia de Copenhague sobre el cambio climático celebrada el pasado mes de diciembre, la teoría científica sobre el cambio climático recibió un duro ataque de los críticos que sostienen que los científicos del clima han suprimido pruebas deliberadamente y que esa tesis científica misma presenta graves errores. El Grupo Intergubernamental sobre el Cambio Climático (IPPC), el grupo mundial de expertos encargado de evaluar el estado de la ciencia del clima, ha sido acusado de parcialidad.

Esos ataques han desconcertado al público mundial. Si los expertos no se ponen de acuerdo en que existe una crisis climática, ¿por qué deben gastar los Estados miles de millones de dólares para abordarla?

La realidad es que los críticos, cuyo número es pequeño, pero sus ataques son agresivos, están desplegando tácticas que han ido perfeccionando durante más de 25 años. Durante su larga campaña, han exagerado enormemente los desacuerdos científicos para detener las medidas contra el cambio climático y han contado con la financiación aportada por grupos de interés especiales, como Exxon Mobil.

  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.

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.
