But this is a herculean undertaking, both technically and politically, as the lack of progress at United Nations climate talks here this week attests. And even if we are able to do this over the next 40 years, we would not slow the rate of warming enough by midcentury to moderate consequences like rising sea levels, the release of methane and carbon dioxide from melting arctic permafrost, and a rise in extreme weather.…  Seguir leyendo »
