Winds of Change - an outline of the Kyoto Protocol: Some Background

摘要

Climate change resulting from emissions of greenhouse gases is one of the biggest environmental challenges facing mankind in the 21st century. No other environmental problem affects all parts of society in such an all embracing way. Scientific observations show that the warming trend seen over the 2oth century is continuing, and the average global temperature over land is now around 10 Celsius warmer than at the end of the 19th century. This increase in temperature correlates rather well with the continental distribution of greenhouse gases as emissions.
