Histeria climática

Tendríamos que haber estado metidos en lo más recóndito de Mongolia para no enterarnos de que la semana pasada, el panel climático de Naciones Unidas, el Grupo Intergubernamental sobre el Cambio Climático, (IPCC) publicó un nuevo informe. Tal vez incluso en las profundidades de Mongolia habríamos escuchado las terribles advertencias de los periodistas. Del estruendo desesperado con el que concluyó el informe, habríamos deducido que el calentamiento global es peor de lo que imaginábamos y que necesitamos emprender acciones rápidas y enérgicas inmediatamente. Habríamos estado mal informados.

El IPCC elaboró un buen informe –un intento de resumir lo que los científicos de todo el mundo saben acerca del calentamiento global. A diferencia de la administración Bush, ocupada en restar importancia a la ciencia, el IPCC nos dice directamente que la humanidad es en gran parte responsable del calentamiento global reciente. Y, a diferencia de Al Gore, que ha viajado por el mundo para advertir que nuestras ciudades pronto podrían estar cubiertas por el mar, se abstiene de ser alarmista.

Pero perdida entre la exageración, está la realidad nada emocionante de que, de hecho, este informe no es más terrible que el que publicó el IPCC en 2001. La obra de este año es en efecto menos terrible en dos formas importantes.

    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.
