El mensaje del Nobel

El Premio Nobel concedido a Al Gore es un homenaje digno de un líder mundial que ha mostrado presciencia, audacia y habilidad al alertar al mundo de los peligros del cambio climático producido por el hombre. Quienes recibieron el Premio Noble junto con Gore son menos conocidos pero no por ello lo merecen menos. El Grupo Intergubernamental sobre el Cambio Climático (IPCC por sus siglas en inglés) es el organismo de Naciones Unidas encargado de evaluar los conocimientos científicos sobre cambio climático y señalarlos a la atención del público y de los encargados del diseño de políticas del mundo. El hecho de que haya recibido el Nobel envía tres mensajes claros.

Primero, los principales científicos mundiales en el campo del clima y la mayoría de los gobiernos del mundo han puesto a las ciencias climáticas en el primer plano de los debates de política global. El cambio climático es complicado. Dominar el tema exige conocimientos en muchas disciplinas científicas, incluyendo la climatología, la oceanografía, la química atmosférica, la ecología, la ingeniería, la política y la economía. Ningún científico o equipo nacional pueden lograrlo por sí solos. Se necesita un esfuerzo a nivel mundial para entender los cambios en todas partes del planeta.

Desde su establecimiento en 1988, el IPCC ha reunido a las mejores mentes científicas de todo el mundo para documentar y explicar lo que se sabe y lo que se ignora sobre el cambio climático inducido por el ser humano. Varios grupos de trabajo preparan informes mediante la revisión escrupulosa de publicaciones científicas. El proceso de revisión es transparente y se invita a los gobiernos a participar mediante la designación de expertos para que formen parte de los diversos grupos de trabajo, la revisión y los comentarios sobre los borradores del IPCC y la aprobación de los informes definitivos.

    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.
