The average temperature of the earth's surface has risen by 0.74 degrees C since the late 1800s. It is expected to increase by another 1.8° C to 4° C by the year 2100 - a rapid and profound change - should the necessary action not be taken. Even if the minimum predicted increase takes place, it will be larger than any century-long trend in the last 10,000 years.
The Kyoto Protocol is generally seen as an important first step towards a truly global emission reduction regime that will stabilize GHG concentrations at a level which will avoid dangerous climate change.
