Resumen de Global doom has not been ruled out
Headlines last week proclaimed the worst-case scenarios for climate change were debunked and not credible. As you might expect things aren't that simple. The stories were sparked by a study by Peter Cox at the University of Exeter, UK, and his colleagues, who attempted to work out how much warming will result from a given increase in carbon dioxide levels. Specifically, if we doubled CO2 levels in the atmosphere and waited for the temperature to stabilise, how much would the world warm? While there is uncertainty about the upper range of climate sensitivity, nearly all major recent studies agree that low values can be ruled out.
