Une année de la terre

STOCKHOLM – Le 22 avril, le monde célèbrera le 45e anniversaire du Jour de la Terre, établi en 1970 pour attirer l'attention sur les défis environnementaux. Ces défis n’ont jamais été aussi importants et urgents qu’aujourd'hui. La combinaison du changement climatique, de l'érosion de la biodiversité et de l'épuisement des ressources naturelles propulse la planète vers un point de basculement, au-delà duquel des objectifs tels que le développement durable et la réduction de la pauvreté seront plus difficiles que jamais à atteindre.

Depuis 1970, les scientifiques ont appris non seulement que l'activité humaine représente le principal moteur des changements environnementaux sur la terre, mais aussi qu’elle est en train de pousser la planète au-delà de ses limites naturelles. Si nous ne procédons pas rapidement à de grands changements, les résultats pourraient être dévastateurs.

Les dirigeants mondiaux semblaient en avoir pris conscience en acceptant il y a cinq ans de limiter le réchauffement climatique au cours de ce siècle à 2º celsius au-dessus des niveaux préindustriels – seuil au-delà duquel nous risquons de déclencher les conséquences plus dévastatrices du changement climatique. Or, aucune mesure énergique pour réduire les émissions de gaz à effet de serre n'a pas été prise. Au contraire, les émissions ont considérablement augmenté ; en conséquence, l'année dernière a été l'année la plus chaude jamais enregistrée.

    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.
