Density-dependent regulation of populations. An increase in the depth of the active layer following global warming. Increased snow cover on newly formed mountains at the end of the Tertiary Period. The net sinks for carbon are vegetation and the oceans. The major radiative gas in the atmosphere is water vapour.
Chlorofluorocarbons absorb infra-red radiation more effectively than water vapour.
The decline in snow cover is the likely cause for the predicted large rise in temperature in the event of global warming in polar regions in the Northern Hemisphere. In the event of global warming the predicted large rise in sea level is a consequence of the melting of the ice caps. All of the above 32. Production of primary chemical compounds. Clumping of individuals.
