The Whitechuck Glacier, Washington, USA, 1973 and again in 2006UKC Articles, Aug 2009© Neil Hinckley / Leor PantilatEs Tresidder is a regular UKC contributor and an environmental consultant. He has written a thought provoking article on climate change and the relationship between climbing and carbon emissions.UKC Article:Environmentalism and Climbing: An Uneasy PartnershipIn this article Es interviews several climbing companies and well known climbing figures, such as Yvon Chouinard fromPatagonia, as well as making his own case for reducing air travel in Europe.Mountainous areas will face glacier retreat, reduced snow cover and winter tourism, and extensive species losses (in some areas up to 60%) under high emissions scenarios by 2080.Intergovernmental Panel on Climate ChangeInstead of preaching that we should all cycle to Ceuse, Es takes a more realistic view of what is possible, what needs to be done and how we can do it; using real world examples of other climbers, skiers and mountain guides that have made a shift in their habits to a more sustainable lifestyle.He states: „Of all the things we do in climbing, travelling by plane has by far the biggest impact.“The overall message of the article is summed up nicely by Patagonia founderYvon Chouinard:?For me there's no difference between a pessimist who says; ?it's all over don't bother doing anything? and an optimist who says; ?oh it's all going to be fine don't bother doing anything?. Either way nothing gets done.?For those of you who are interested in travelling to the Alps this summer, Es has drawn a comparison table of carbon emissions – see below:Example Carbon Emissions – Travel to Chamonix
