¿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.

    Populist Plutocracy and the Future of America

    • In the first year of his presidency, Donald Trump has consistently sold out the blue-collar, socially conservative whites who brought him to power, while pursuing policies to enrich his fellow plutocrats. 

    • Sooner or later, Trump's core supporters will wake up to this fact, so it is worth asking how far he might go to keep them on his side.

    The Man Who Didn’t Save the World

    A Saudi prince has been revealed to be the buyer of Leonardo da Vinci's "Salvator Mundi," for which he spent $450.3 million. Had he given the money to the poor, as the subject of the painting instructed another rich man, he could have restored eyesight to nine million people, or enabled 13 million families to grow 50% more food.

    Two Myths About Automation

    While many people believe that technological progress and job destruction are accelerating dramatically, there is no evidence of either trend. In reality, total factor productivity, the best summary measure of the pace of technical change, has been stagnating since 2005 in the US and across the advanced-country world.

    The Hungarian Government’s Failed Campaign of Lies

    The Hungarian government has released the results of its "national consultation" on what it calls the "Soros Plan" to flood the country with Muslim migrants and refugees. But no such plan exists, only a taxpayer-funded propaganda campaign to help a corrupt administration deflect attention from its failure to fulfill Hungarians’ aspirations.
