Climate change is a fact. The earth is warming – and the certainty is greater than 90% that human activity is the cause.
The United Nations Report published in February 2007 gives us, what are now as close to facts as can be, that human activity is to blame for rising levels of carbon dioxide, methane and nitrous oxide in the atmosphere. These are just some of the UNFCCC’s findings:-
Carbon dioxide has increased from 280ppm in 1750 to 379ppm in 2005.
Methane has increased from a pre-industrial level of 715ppb to

Surface temperatures over 11 of the last 12 years have been the hottest since records began in 1850.
Since observations began in 1961, ocean average temperatures to a depth of 3,000 metres have increased, causing seawater expansion.
We have less than 10 years left to make huge changes, or global warming could become completely
