Den Westen beim Klimawandel zusammenbringen

WASHINGTON, DC – Präsident Barack Obama hat den Klimawandel als eine der bedeutsamsten Herausforderungen unserer Zeit bezeichnet und drängt mit einem Gesetz zur Emissionsbegrenzung und zum Emissionsrechtehandel voran, wobei er gleichzeitig die Vereinigten Staaten wieder vollständig in die Verhandlungen der Vereinten Nationen einbindet.

Doch bedeutet diese veränderte Haltung nicht, dass die USA und die Europäische Union sich jetzt einig sind, wie dem Klimawandel beizukommen ist.

  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.

    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.
