Resumen de Climate's seven deadly sinners
It's a chart that no one wants to top, but global warming's worst offenders, in absolute terms, are the US, China, Russia, Brazil, India, Germany and the UK. New calculations suggest that these nations are responsible for more than 60 percent of the global warming between 1906 and 2005. Damon Matthews of Concordia University in Montreal, Canada, and his colleagues calculated national contributions to warming by weighting each type of emission according to the atmospheric lifetime of the temperature change it causes.
