Sea levels have risen 10-20 cm which is caused mainly by the expansion of warming oceans.
Most glaciers in temperate regions of the world and along the Antarctic Peninsula are in retreat;
and records show Arctic sea-ice has thinned by 40% in recent decades in summer and autumn.
B. Global warming is also explained by the greenhouse effect. The greenhouse effect refers to the role played by gases which effectively trap energy from the Sun in the Earth's atmosphere. Without them, the planet would be too cold to have any form of life as we know it.
The most important of these gases in the natural greenhouse effect is water vapour, but concentrations of that are changing little and it plays almost no role in modern human-induced greenhouse warming.
Other greenhouse gases include carbon dioxide, methane ['mi:9ein] and nitrous oxide, which are thrown into the atmosphere by modern industry and agriculture.
Their concentration in the atmosphere is going up - the concentration of carbon dioxide has risen by more than 30% since 1800.
C. The majority of climate scientists accept the theory that an increase in these gases will cause a rise in the Earth's temperature, and say that human activites are to blame
