Ausstieg aus fossilen Brennstoffen

BERN – Der Zeitpunkt für einen Ausstieg aus fossilen Brennstoffen war noch nie so günstig. Weltweite Temperaturrekorde, drastisch sinkende Preise bei fossilen Brennstoffen, historische Investitionen in erneuerbare Energieträger und der weltweite Druck, den Verpflichtungen im Bereich Klimaschutz auch nachzukommen, bilden den idealen Rahmen für diesen weitreichenden Wandel.

Dieser Wandel könnte dringender nicht sein. In dem im letzten Dezember in Paris verhandelten Klimaschutzabkommen der Vereinten Nationen wird die Begrenzung der globalen Erwärmung auf 2 Grad über vorindustriellem Niveau erneut als absolute Obergrenze bestätigt, deren Überschreitung für den Planeten katastrophale Folgen hätte. In dem Abkommen bekannte man sich allerdings auch dazu, „Anstrengungen zu unternehmen“, die globale Erwärmung auf 1,5 Grad zu beschränken. Aufgrund der jüngsten von der NASA veröffentlichten Daten gilt es, diese Untergrenze als Gebot der Stunde zu betrachten.

Die neuen Daten bestätigen, dass 2015 das wärmste Jahr seit Beginn der Aufzeichnungen war und sie zeigen, dass sich die Temperaturrekorde auch in den ersten zwei Monaten dieses Jahres fortsetzten. Angaben der NASA zufolge lagen die Temperaturen im Februar im Vergleich zu den Werten von 1951 bis 1980 1,35 Grad über dem Durchschnitt.

    Angela Merkel’s Endgame?

    The collapse of coalition negotiations has left German Chancellor Angela Merkel facing a stark choice between forming a minority government or calling for a new election. But would a minority government necessarily be as bad as Germans have traditionally thought?

    Preparing for the Trump Trade Wars

    In the first 11 months of his presidency, Donald Trump has failed to back up his words – or tweets – with action on a variety of fronts. But the rest of the world's governments, and particularly those in Asia and Europe, would be mistaken to assume that he won't follow through on his promised "America First" trade agenda.

    The Platform Economy

    While developed countries in Europe, North America, and Asia are rapidly aging, emerging economies are predominantly youthful. Nigerian, Indonesian, and Vietnamese young people will shape global work trends at an increasingly rapid pace, bringing to bear their experience in dynamic informal markets on a tech-enabled gig economy.

    Profiles in Discouragement

    One day, the United States will turn the page on Donald Trump. But, as Americans prepare to observe their Thanksgiving holiday, they should reflect that their country's culture and global standing will never recover fully from the wounds that his presidency is inflicting on them.

    How Women Shape Coups

    In Zimbabwe, as in all coups, much behind-the-scenes plotting continues to take place in the aftermath of the military's overthrow of President Robert Mugabe. But who the eventual winners and losers are may depend, among other things, on the gender of the plotters.

    The Abnormality of Oil

    At the 2017 Abu Dhabi Petroleum Exhibition and Conference, the consensus among industry executives was that oil prices will still be around $60 per barrel in November 2018. But there is evidence to suggest that the uptick in global growth and developments in Saudi Arabia will push the price as high as $80 in the meantime.

    The Saudi Prince’s Dangerous War Games

    Saudi Arabia’s Crown Prince Mohammed bin Salman is working hard to consolidate power and establish his country as the Middle East’s only hegemon. But his efforts – which include an attempt to trigger a war between Israel and Hezbollah in Lebanon – increasingly look like the work of an immature gambler.
