La respuesta de la naturaleza al riesgo climático

LONDRES – Casi la mitad de la población mundial -unos 3.500 millones de personas- vive cerca de la costa. En tanto el cambio climático exacerba los efectos de las tormentas, las inundaciones y la erosión, la vida y la subsistencia de cientos de millones de esas personas están en riesgo. En verdad, la última edición del Informe de Evaluación de Riesgo Global del Foro Económico Mundial ve la imposibilidad de adaptarse a los efectos del cambio climático como el riesgo más importante, en términos de impacto, para las sociedades y las economías de todo el mundo.

Más allá de poner vidas en peligro, las tormentas más frecuentes y más fuertes podrían costar muchos miles de millones de dólares, debido a los daños a la infraestructura y a los ingresos perdidos provenientes de la agricultura, la pesca y el turismo. Y, como observó recientemente la publicación Harvard Business Review, el costo proyectado aumenta con cada nuevo estudio. Aun así, la comunidad internacional actualmente invierte en mitigar el riesgo menos de una quinta parte de lo que gasta en responder a los desastres naturales.

Cuando hablamos de riesgo climático, una onza de prevención vale tanto como una libra de cura.  Como dijo Rebecca Scheurer, directora del Centro Global de Preparación para Desastres de la Cruz Roja, "Gastamos millones de dólares en brindar respuesta, pero si invirtiéramos una mayor parte de esos recursos en la planificación salvaríamos a más personas. Es tan simple como eso".

    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.
