Widespread melting of snow and ice is observed as well as a rising  global sea level. In short, warming of the climate system is  unequivocal, the fourth assessment report of the intergovernmental panel  of climate change (IPCC) concludes.<\/strong><\/p>\n<p><!--more-->The main difference between this report and the previous one from 2001  is that the IPCC now qualifies human activities as the \u0152very likely\u00b9  (&gt;90% chance) cause for the global warming. In 2001 the term \u0152likely\u00b9  was used. Industrial activities and agriculture have pushed up the  levels of greenhouse gases carbon dioxide, methane and nitrous oxide to  levels unprecedented in geological history.<\/p>\n<p>In fact, global warming has only just begun. Between 1990 and 2005 the  average global temperature increased by 0.33 degrees Celsius. But the  rate of increase is accelerating. For the next two decades the IPCC  predicts a warming of 0.2 degrees Celsius per decade. More heat waves  and floods are \u0152very likely\u00b9. More intensive tropical storms on the  scale of Katrina are considered \u0152likely\u00b9. Because of the timescales  associated with climate processes and feedbacks, anthropogenic warming  and sea level rise will continue for centuries, even if greenhouse gas  emissions were to be stabilised as of now.<\/p>\n<p>Is this already alarming enough? Not yet, German climatologist Stefan  Rahmstorf writes in a Science article that was published last week,  \u00b3Previous projections, as summarised by the IPCC, have not exaggerated  but may in some respects even have underestimated the change, in  particular for sea level.\u00b2 Rahmstorf and colleagues arrive at this  conclusion after comparing the predicted sea level rises with the  observed data from 1990 onwards. Satellite data show a rise of 3.3  millimetres per year, while the IPCC estimated 2 millimetres per year as  most probable. Thermal expansion of the oceans and glacier melting were  the main contributors. But increasing contributions are to be expected  from Greenland and Antarctica.<\/p>\n<p>\u00b3Clearly, the 20 percent CO2 reduction that the European Commission  agreed upon last January is not enough,\u00b2 according to Dorette Corbey,  socialist member of the European Parliament. \u00b3The reduction should have  been 30 percent in order to limit global warming to 2 degrees maximum,\u00b2  Corbey says. She thinks Europe should take the political lead in cutting  CO2 emissions. \u00b3Every week a new coal plant opens up in China. We  should make sure they should be equipped to capture and store the  greenhouse gases.\u00b2<\/p>\n<p>After this \u0152scientific basis\u00b9 report, IPCC will publish other scientific  reports in April. These coming reports will cover how to adapt to  climate change, and how to mitigate climate change with measures for  greenhouse gas emission reduction.<\/p>\n<p>More information on www.ipcc.ch<\/p>\n<p>copyright  \u00a9 Het Inzicht \/ Jos Wassink, 2007<\/p>\n","protected":false},"excerpt":{"rendered":"<p>GreenPrices Weekly, 5 February, 2007 &#8211; Eleven of the last twelve years were the warmest since records began.
