¿Podremos sobrevivir al “Antropoceno”?

Durante los últimos tres siglos, los efectos del ser humano sobre el medio ambiente global se han intensificado. Lo que es más importante, nuestras emisiones de bióxido de carbono podrían provocar patrones climáticos que se alejen significativamente de su curso natural durante muchos milenios.

Parece adecuado asignar el término “Antropoceno” a la actual era geológica, dominada de muchas formas por el ser humano, como complemento del Holoceno –el período cálido de los últimos 10-12 milenios. Podría decirse que el Antropoceno comenzó en los últimos años del siglo XVIII, cuando los análisis del aire atrapado en el hielo polar muestran el principio de las concentraciones globales de CO2  y metano. Esta fecha también coincide con el diseño de la máquina de vapor de James Watt en 1784.

Ya desde 1873, cuando el geólogo italiano Antonio Stoppani se refirió a la “era antropozoica” definida por “una nueva fuerza telúrica, que se puede comparar en poder y universalidad a las grandes fuerzas de la Tierra", se observaba la influencia de la humanidad sobre el medio ambiente.

    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.
