It's said that by the time a baby born today is 80 years old, the world will be 6 and a half degrees warmer than it is now.

Scientists have determined that the ice in Greenland and the Arctic is melting so rapidly that much of it could be gone by the end of the century.

The four-year study of the Arctic climate involved an international team of more than 300 scientists. They used a number of climate models and made a "moderate estimate" of future emissions of carbon dioxide and other greenhouse gases that are widely believed to be contributing to the recent warming trend of the Earth's climate.

• Low-lying coastal areas in Florida and Louisiana could be flooded by the sea. A 1.5 feet (50-centimeter) rise in sea level could cause the coastline to move 150 feet (45 meters) inland, resulting in substantial economic, social, and environmental impact in low-lying areas.

• The health and food security of some indigenous peoples would be threatened, challenging the survival of some cultures.

• Should the Arctic become ice-free in summer, it is likely that polar bears and some seal species would become extinct.

• The melting of so much ice, and the resulting addition of so much fresh water to the ocean, could impact the circulation of currents and affect regional climate.

The list goes even further on.

Extra greenhouse gases are produced through activities which release carbon dioxide, methane, nitrous oxide and ozone CFCs (chlorofluorocarbons). These activities include:

Burning coal and petrol, known as 'fossil fuels'

Cutting down of rainforests and other forests

Animal waste which lets off methane

BACKGROUND

Global warming is the increase in the average temperature of the Earth's near-surface air and oceans in recent decades and its projected continuation.

Increasing global temperature will cause sea level to rise, and is expected to increase the intensity of extreme weather events and to change the amount and pattern of precipitation. Other effects of global warming include changes in agricultural yields, trade routes, glacier retreat, species extinctions and increases in the ranges of disease vectors.

This world will be completly different by the time your grandchildren's grandchildren's children come into this world. It's already changed enough in these past 10 years.
