Global warming is the increase in the average temperature of Earth's near-surface air and oceans since the mid-20th century and its projected continuation.... An increase in global temperature will cause sea levels to rise and will change the amount and pattern of precipitation, probably including expansion of subtropical deserts.… Other likely effects include changes in the frequency and intensity of extreme weather events, species extinctions, and changes in agricultural yields. Warming and related changes will vary from region to region around the globe, though the nature of these regional variations are uncertain.
That is because you will be directed to 'Wikipedia'1. The Wikipedia page goes on to predict glacial retreat, Arctic shrinkage including long-term shrinkage of Greenland ice sheet Ocean acidification will lead to the extinction of between 18% to 35% of animal and plant species by 2050. Horrifying predictions of temperature rises are given in graphics, with a note that not all effects of global warming are accurately predicted by the climate models used by the IPCC. Ah ha! a small concession to the sceptics? Not at all, the encyclopaedia merely wants us to worry more because, "For example, observed Arctic shrinkage has been faster than that predicted."
This is, of course, the 'full throttle' version of the theory of man-made global warming, as advanced by certain scientists and green groups. (Apart from the highly politicised IPCC summaries written by activists including government representatives with the aim of directing political policies, the sources are variously, RealClimate.org, James Hansen at the Goddard Institute, and so on. That is three names for essentially the same outfit.)
In general, Wikipedia reprints the IPCC notes for policy makers, produced by it political steering committees, as a kind of holy writ. Actually, to say something is the 'view of the IPCC' is a shorthand, because many of the past and present authors of the IPCC reports do NOT agree with particular claims. Naturally, given their origins, the reports consist of endless weasel words and hair-splitting distinctions between degrees of plausibility. 'Very likely' to happen, 'quite likely', 'likely'. None of these complications bog down Wikipedia, where the science is all very straightforward and unremittingly alarmist. To confirm its accuracy, the Global Warming page boasts a gold star meaning it has been approved by the Wikipedia system as one of the best, the most objective and the most encyclopaedic.
