The Earth's ice cover acts as a protective mirror, reflecting a large share of the sun's heat back into space and keeping the planet cool.

Scientists suspect that the enhanced melting is among the first observable signs of human-induced global warming, caused by the unprecedented release of carbon dioxide and other greenhouse gases

Page 5: Global warming

The Earth's ice cover is melting in more places and at higher rates than at any time since record keeping began

Loss of the ice would not only affect the global climate, but would also raise sea levels

Wildlife is already suffering as a result of global ice melt-particularly at the poles, where marine mammals, seabirds, and other creatures depend on food found at the ice edge

Methane (CH4) is a relatively potent greenhouse gas with a high global warming potential that remains in the atmosphere for approximately 9-15 years.

Page 7: Global warming

Methane is over 20 times more effective in trapping heat in the atmosphere than carbon dioxide (CO2)

It is emitted from a variety of natural and human-influenced sources (agricultural activities).

Page 8: Global warming

It means the permanent destruction of forests and woodlands

Page 9: Global warming

Alteration of local and global climates.

Extinction of species which depend on the forest for survival.

Forests contain more than half of all species on our planet - as the habitat of these species is destroyed, so the number of species declines.

Reduce the electric energy consume

Electricity does cause a large quantities of carbon dioxide (CO2), which affect the

atmosphere
