| | Some Economics of Global Warming |
 | | Demography, economics, biology, and the technology sciences are needed to project emissions, atmospheric chemistry, oceanography, biology, and meteorology are needed to translate emissions into climates; biology, agronomy, health sciences, economics, sociology, and glaciology are needed to identify and assess impacts on human societies and natural ecosystems. |
 | | To the first question, the answer is that average global temperature--summer and winter, both hemispheres, night and day--has apparently risen by half a degree in the last hundred years, but whether "as predicted" depends on what qualifications one reads into the predictions. |
 | | And if they deal with global emissions, they have to make some assumption about the distribution of abatement efforts among nations, especially among the developing countries, which, including China, account for about a quarter of emissions now and would be expected to account for half by the middle of the next century. |
