Resources are finite, even the sun, but new technologies will help us adapt over the next say 50 years. Meanwhile approximately 5 degrees further north Turoa has had record snowfall and there will be sking until Jan 2009!!!!! http://www.nzherald.co.nz/nz/news/article.cfm?c_id=1&objectid=10533086 Ecoglobe – 2008 tempertures are falling though.

Many things are growing: GHG emissions, population size, water shortages, deforestation, loss of biodiversity, depletion of fossil fuels, frequencies of droughts and floods, the loss of glacier volume and more. Constants are the size of the planet and the blatant incompetence of our leaders of all political colours to understand that resources are finite and growth is the sure road to total depletion, wars for the last resources, collapse and the demise of mankind.

From the WGMS <a href="http://www.geo.unizh.ch/wgms/mbb/mbb9/sum06.html" rel="nofollow">preliminary figures for 2006</a>: <blockquote>The average mass balance of the glaciers with available long-term mass balance series around the world continues to decrease, with tentative figures indicating a further thickness reduction of 1.4 m w.e. during the hydrological year 2006. <strong>This continues the trend in accelerated ice loss during the past two and a half decades</strong> and brings the total loss since 1980 at more than 10.5 m w.e.</blockquote> [Emphasis mine] So, Steve, got any other vapid assertions? Thanks rata.

From the WGMS preliminary figures for 2006:

The average mass balance of the glaciers with available long-term mass balance series around the world continues to decrease, with tentative figures indicating a further thickness reduction of 1.4 m w.e. during the hydrological year 2006. This continues the trend in accelerated ice loss during the past two and a half decades and brings the total loss since 1980 at more than 10.5 m w.e.

So, Steve, got any other vapid assertions?

I'm looking forward to comparing my photos on the Vanoise glaciers with those of a friend who lived there in the 1970s. This site is looking GREAT, Gareth, and is as interesting and well-informed as ever. Much the same story in the French Alps, where I’ve just been.

El Ninos bring cooler weather and more snow, La Ninas the reverse, so the frequency and strength of those events will dominate the process (PDO/IPO link, perhaps) - and be overlaid on the underlying warming trend. Also worth noting that NIWA's RCM suggests that warming will be particularly intense in the Alps, so that trend may steepen as the decades go by.
