Polar bears are especially at risk if ice sheets continue to melt
The facts are clear: Global temperatures have risen 0.6°C in the last 140 years and most scientists predict that the Earth will warm 1.4 - 5.8°C by 2100. An overwhelming majority of climate experts agree the main reason for this is due to certain gases emitted by fossil fuel burning and other human activities such as intensive agriculture. These greenhouse gases, (the major one being CO2) are causing more of the sun’s energy to be trapped inside the Earth's atmosphere, increasing the global temperature.
Member countries to the United Nations Framework Convention on Climate Change, UNFCCC, came up with the Kyoto Protocol. Ratified by 84 countries, the protocol forces over 30 industrialised countries to reduce their emissions by an average of five percent below what they pumped out in 1990. They have until 2012 to do this.
A number of "flexible mechanisms" in the Kyoto Protocol are helping countries to reach their goals:
