Misc: Global warming

From the article:
The report says this point will be two degrees centigrade above the average world temperature prevailing in 1750 before the industrial revolution, when human activities - mainly the production of waste gases such as carbon dioxide (CO2), which retain the sun's heat in the atmosphere - first started to affect the climate. But it points out that global average temperature has already risen by 0.8 degrees since then, with more rises already in the pipeline - so the world has little more than a single degree of temperature latitude before the crucial point is reached.
