Il Cambiamento Climatico e la Chiesa Cattolica

ROMA – Papa Francesco chiede al mondo di agire contro il riscaldamento globale, e molti conservatori negli Stati Uniti sono sul piede di guerra. Il papa dovrebbe attenersi alla morale, dicono, e non avventurarsi nella scienza. Ma, poiché il dibattito sul clima si svolge quest’anno, la maggior parte dell’umanità troverà il messaggio di Francesco convincente: sono necessarie sia la scienza che la morale, per ridurre i rischi per il nostro pianeta.

Il primo punto da notare è che la stragrande maggioranza degli americani è d’accordo con l’appello di Francesco all’azione per il clima. Purtroppo, le loro opinioni non sono rappresentate nel Congresso degli Stati Uniti, che tutela le principali compagnie carbonifere (“Big Coal”) e petrolifere (“Big Oil”), non il popolo americano. L’industria dei combustibili fossili investe pesantemente in attività di lobbismo e nelle campagne elettorali di membri del Congresso come i senatori Mitch McConnell e James Inhofe. La crisi climatica del mondo è stata aggravata da una crisi di democrazia negli Stati Uniti.

In un sondaggio sugli Americani, condotto nel gennaio 2015, la stragrande maggioranza degli intervistati (78%) ha dichiarato che, “se non si fa nulla per ridurre il riscaldamento globale”, le conseguenze future per gli Stati Uniti potranno essere “piuttosto gravi” o “molto gravi”. Circa la stessa percentuale (74%) ha dichiarato che se non si fa nulla per ridurre il riscaldamento globale, le generazioni future verranno colpite “moderatamente”, “molto” o “moltissimo”. Più significativamente forse, il 66% ha dichiarato che sarebbe “più probabile” per loro sostenere un candidato che riconosca il cambiamento climatico in atto e richieda il passaggio alle energie rinnovabili, mentre per il 12% sarebbe “meno probabile” sostenere un tale candidato.

    The Brexit Surrender

    European Union leaders meeting in Brussels have given the go-ahead to talks with Britain on post-Brexit trade relations. But, as European Council President Donald Tusk has said, the most difficult challenge – forging a workable deal that secures broad political support on both sides – still lies ahead.

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

  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.
