Nessun agnostico nella trincea del clima

SYDNEY – Durante un recente volo di 14,5 ore da Los Angeles a Sydney, ho avuto modo di leggere la collezione di saggi dell’editorialista Charles Krauthammer, Things that Matter. Ha reso il volo inquietante.

Ho apprezzato gli scritti di Krauthammer per anni, ma c’era qualcosa nel suo libro che ho trovato profondamente preoccupante: la sua descrizione di se stesso come un “agnostico” sul cambiamento climatico. Lui “ritiene istintivamente che non può essere molto salutare immettere grandi quantità di anidride carbonica nell’atmosfera”, e ancora lui “è ugualmente convinto che quelli che suppongono di sapere esattamente dove porta tutto ciò parlano senza cognizione di causa”.

La parola che ho trovato più irritante è stata “agnostico” – non solo perché Krauthammer è uno scienziato qualificato, ma anche perché la parola è stata usata ripetutamente dall’ex Primo Ministro australiano John Howard quando si è rivolto a un gruppo di negatori del cambiamento climatico a Londra negli ultimi mesi del 2013. “Parte del problema con questo dibattito”, ha detto Howard agli scettici riuniti, “è che per alcuni dei fanatici coinvolti la loro causa è diventata un surrogato della religione”.

    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.
