L’attaque bidon sur la science du climat

NEW YORK –A la veille tout comme aux lendemains de la conférence sur le changement climatique de Copenhague en décembre dernier, la science du changement climatique a subi les assauts de critiques soutenant que les climatologues ont délibérément omis certaines preuves – et que cette science est elle-même extrêmement déficiente. Le Groupe d’experts intergouvernementaux sur l’évolution du climat (GIEC), un panel international d’experts chargés d’évaluer l’état de la science du climat, a été accusé de partialité.

L’opinion publique internationale est déconcertée par ces attaques. Si les experts n’arrivent pas à s’accorder sur l’existence d’une crise climatique, pourquoi les gouvernements du monde entier dépensent-ils des milliards de dollars pour y répondre ?

Le fait est que les sceptiques, peu nombreux mais agressifs dans leurs attaques, déploient des tactiques qu’ils ont affinées durant plus de 25 ans. Au cours de leur longue campagne, ils ont grandement exagéré les désaccords entre scientifiques afin de faire arrêter toute action contre le changement climatique, le tout financé par des groupes d’intérêt comme Exxon.

    For four decades, China has achieved unprecedented economic growth under a centralized, authoritarian political system, far outpacing growth in the Western liberal democracies. So, is Chinese President Xi Jinping right to double down on authoritarianism, and is the “China model” truly a viable rival to Western-style democratic capitalism?

    Whither the Multilateral Trading System?

    The global economy today is dominated by three major players – China, the EU, and the US – with roughly equal trading volumes and limited incentive to fight for the rules-based global trading system. With cooperation unlikely, the world should prepare itself for the erosion of the World Trade Organization.

    The Globalization of Our Discontent

    Globalization, which was supposed to benefit developed and developing countries alike, is now reviled almost everywhere, as the political backlash in Europe and the US has shown. The challenge is to minimize the risk that the backlash will intensify, and that starts by understanding – and avoiding – past mistakes.

    A Better British Story

    Despite all of the doom and gloom over the United Kingdom's impending withdrawal from the European Union, key manufacturing indicators are at their highest levels in four years, and the mood for investment may be improving. While parts of the UK are certainly weakening economically, others may finally be overcoming longstanding challenges.

    The UK’s Multilateral Trade Future

    With Brexit looming, the UK has no choice but to redesign its future trading relationships. As a major producer of sophisticated components, its long-term trade strategy should focus on gaining deep and unfettered access to integrated cross-border supply chains – and that means adopting a multilateral approach.
