What do you think is Population Density? How does population density affect global warming?

Per-capita greenhouse gas emissions may drop,

Explanation:

Per-capita greenhouse gas emissions may drop, but the population bulge will continue to contribute to a dangerous increase in greenhouse gases in the atmosphere. Time is short, but it not too late to stop runaway global warming.

Population density allows for broad comparison of settlement intensity across geographic areas. When comparing population density values for different geographic areas, then, it is helpful to keep in mind that the values are most useful for small areas, such as neighborhoods. For larger areas (especially at the state or country scale), overall population density values are less likely to provide a meaningful measure of the density levels at which people actually live, but can be useful for comparing settlement intensity across geographies of similar scale.
