Since 1850 there has been a mean rise in global temperature of approximately 1°
C (approximately 1.8° F). Even a limited rise in average surface temperature
might lead to at least partial melting of the polar icecaps and hence a major
rise in sea level, along with other severe environmental disturbances. An
example of a runaway greenhouse effect is Earth's near-twin planetary neighbor
Venus. Because of Venus's thick CO2 atmosphere, the planet's cloud-covered
