The ppt presentation Policy-relevance of the Working Group II Contribution to IPCC AR4 (Fourth Assessment Report) by Jean-Pascal van Ypersele (IPCC Vice-chair) "with the kind collaboration of Chris Field, IPCC WGII Co-chair, and the IPCC Secretariat" at a UNFCC conference in Barcelona, 3 November 2009, contains "cases studies on impacts", among them on page 5 an assessment of the Glacial retreat in the Himalaya
•receding and thinning of Himalayan glaciers can be attributed primarily to the global warming; in addition, high population density near these glaciers and consequent deforestation and land-use changeshave adversely affected these glaciers
•the total glacial area will likely shrink from the present 500,000 to 100,000 km2(or disappear entirely) by the year 2035
•the 15,000 Himalayan glaciers form a unique reservoir of water which in turn, is the lifeline of millions of people in South Asian countries
•it is likely that glacial melt will turn the big Asian river systems into seasonal rivers and affect economies in the region
The reason for having this desinformation still on the web may be an attempt for keeping the documents historically in order - the talk has seemingly given in this way, and the original, unchanged material is provided on the IPCC web-site. This reason would have to be applauded. However, it shows that the false claim of a consensus view in this matter was not just somewhere hidden in a technical document, but used prominently by leading IPCC persons, namely a vice chair of AR4, and - as it seems - the new chair of WG 2.
I have asked Chris Field for an explanation.
