Terrestrial secondary vegetation ii. Marine ecosystems iii. Agricultural grasslands v. In the event of global warming, the temperature rise in winter may be greater in polar regions than that predicted for the Northern Hemisphere as a whole. The oceans are the biggest sink for carbon.
Water vapour is the major radiative gas based on the amount in the atmosphere.
The predicted rise in sea level is the result of melting of ice caps. All objects above absolute zero emit radiation. The host population must reach a critical density. Individuals in the population suffer from malnutrition. Small family sizes.
