A major new study in Science magazine, "Future CO2 Emissions and Climate Change from Existing Energy Infrastructure" (subs. req'd), makes a powerful case for rapid deployment of low-carbon technology.
The study, one of whose authors is climatologist Ken Caldeira, looks at current and future emissions from existing energy infrastructure. It concludes that if the world built no new polluting infrastructure, we would end up with "mean warming of 1.3°C (1.1° to 1.4°C) above the pre-industrial...
