Global Warming

During the last week in January, leading Scientists from around the globe met in Paris, France as part of the Intergovernment Pannel on Climate Change (IPCC). The IPCC report was published on February 2, 2007. Its key conclusions were that:

• Warming of the climate system is unequivocal

• Most of the observed increase in globally averaged temperatures since the mid-20th century is very likely due to the observed increase in anthropogenic greenhouse gas concentrations .

• Hotter temperatures and rises in sea level "would continue for centuries" no matter how much humans control their pollution.

• The probability that this is caused by natural climatic processes is less than 5%

• World temperatures will probably rise by 1.1 to 6.4°C and that:

• Sea levels will probably rise by 18 to 59cm

• It is more than 66% certain that there will be an increase in droughts, tropical cyclones and extreme high tides.

• Both past and future anthropogenic carbon dioxide emissions will continue to contribute to warming and sea level rise for more than a millennium.

• Global atmospheric concentrations of carbon dioxide, methane and nitrous oxide have increased markedly as a result of human activities since 1750 and now far exceed pre-industrial values over the last 650,000 years.
