Third footnote

Subtitled, perhaps, the revenge of the nerds. The IPCC Summary for Policymakers is just that: a summary. The real facts are contained in the technical summary, which will not be edited by politicians and will be released to the public.

Some highlights, not included in the 23-page already released summary:

- "More than one-sixth of the world population live in glacier- or snowmelt-fed river basins and will be affected by decrease of water volume." And depending on how much fossil fuels are burned in the future, "262-983 million people are likely to move into the water-stressed category" by 2050.

- Global warming could increase the number of hungry in 2080 by between 140 million and 1 billion, depending on how much greenhouse gas is emitted in coming decades.

- "Overall, a two- to three-fold increase of population to be flooded is expected by 2080."

- Malaria, diarrheal diseases, dengue fever, tick-borne diseases, heat-related deaths will all rise with global warming. But in the United Kingdom, the drop in cold-related deaths will be bigger than the increase in heatstroke-related deaths.

- In eastern North America, depending on fossil-fuel emissions, smog will increase and there would be a 4.5 percent increase in smog-related deaths.

- Because global warming will hurt the poor more, there will be more "social-equity" concerns and pressure for governments to do more.

The technical summary will also include the portions deleted from the policymakers' summary.
