Stolpern im Dunkeln

SAO PAULO – Wie immer bei gut gemeinten Aktionen ist auch gegen Earth Hour schwer etwas zu sagen. Am Samstag den 27. März, um Punkt 20:30 Uhr, demonstrierte fast eine Milliarde Menschen in über 120 Ländern ihren Wunsch, etwas gegen die Erderwärmung zu tun. Dafür schalteten sie eine Stunde lang das Licht ab. Aus offizieller Solidarität blieben auch manche der berühmtesten Sehenswürdigkeiten der Welt dunkel, wie beispielsweise das Opernhaus in Sydney, die Pyramiden in Gizeh sowie auch die Verbotene Stadt in Peking, das Empire State Building in New York, der Londoner Big Ben, der Eiffelturm in Paris und die Skylines von Hongkong und Las Vegas.

Was immer diese Kampagne auch sonst noch sein mag, fest steht, dass Earth Hour mit Sicherheit einer der erfolgreichsten jemals ersonnenen Werbegags ist. Seit die Aktion im Jahr 2007 erstmals in Sydney vom lokalen Büro des World Wildlife Fund organisiert wurde, stiegen Beliebtheit und Beteiligung (auf individueller und offizieller Ebene) sprunghaft an – so dass es mittlerweile kaum einen Winkel auf dieser Welt gibt, der von dieser Kampagne verschont bleibt. Greg Bourne, CEO des World Wildlife Fund in Australien formuliert es so: „Alle Menschen von Casablanca bis zu den Safari-Camps in Namibia und Tansania beteiligen sich.”

Aber hat Earth Hour irgendetwas dazu beigetragen, die Erderwärmung zum Stillstand zu bringen – oder wenigstens zu verlangsamen? Nicht allzu viel.

    Empowering China’s New Miracle Workers

    China’s success in the next five years will depend largely on how well the government manages the tensions underlying its complex agenda. In particular, China’s leaders will need to balance a muscular Communist Party, setting standards and protecting the public interest, with an empowered market, driving the economy into the future.

    The Sovereignty that Really Matters

    The preference of some countries to isolate themselves within their borders is anachronistic and self-defeating, but it would be a serious mistake for others, fearing contagion, to respond by imposing strict isolation. Even in states that have succumbed to reductionist discourses, much of the population has not.

    Resurrecting Creditor Adjustment

    When the Bretton Woods Agreement was hashed out in 1944, it was agreed that countries with current-account deficits should be able to limit temporarily purchases of goods from countries running surpluses. In the ensuing 73 years, the so-called "scarce-currency clause" has been largely forgotten; but it may be time to bring it back.

    Trump’s Republican Collaborators

    Republican leaders have a choice: they can either continue to collaborate with President Donald Trump, thereby courting disaster, or they can renounce him, finally putting their country’s democracy ahead of loyalty to their party tribe. They are hardly the first politicians to face such a decision.

    How Money Could Unblock the Brexit Talks

    With talks on the UK's withdrawal from the EU stalled, negotiators should shift to the temporary “transition” Prime Minister Theresa May officially requested last month. Above all, the negotiators should focus immediately on the British budget contributions that will be required to make an orderly transition possible.

    Is Vladimir Putin Losing His Grip?

    In recent decades, as President Vladimir Putin has entrenched his authority, Russia has seemed to be moving backward socially and economically. But while the Kremlin knows that it must reverse this trajectory, genuine reform would be incompatible with the kleptocratic character of Putin’s regime.

    Don’t Bank on Bankruptcy for Banks

    As a part of their efforts to roll back the 2010 Dodd-Frank Act, congressional Republicans have approved a measure that would have courts, rather than regulators, oversee megabank bankruptcies. It is now up to the Trump administration to decide if it wants to set the stage for a repeat of the Lehman Brothers collapse in 2008.
