• Resumen

  • Despite decades of research, nobody is really sure how sensitive the climate is to carbon dioxide. According to the most recent Intergovernmental Panel on Climate Change report, doubling the CO^sub 2^ concentration in the atmosphere would raise global temperatures between 1.5 and 4.5°C. But there's no consensus on this climate sensitivity. To estimate how much the sensitivity varies, Gary Russell of the NASA Goddard Institute for Space Studies in New York and colleagues ran a climate model repeatedly. Each run of the model kicked off with a different concentration of CO^sub 2^ in the atmosphere. In each case they ran the model for 100 years to see how much the world warmed as CO^sub 2^ levels increased.
