Afsmeltningen af Himalayas gletchere ophørt?!

Håber I kan hjælpe mig!

Are Himalayan glaciers beating a rapid retreat in the face of global warming? That would seem to be the case, according to a flurry of recent reports by BBC and other mass media. But the picture is more complex—and poses scientific puzzles, according to a review of satellite and ground measurements released by India's Ministry of Environment and Forests earlier this week. The report, by senior glaciologist Vijay Kumar Raina, formerly of the Geological Survey of India, seeks to correct a widely held misimpression based on measurements of a handful of glaciers: that India's 10,000 or so Himalayan glaciers are shrinking rapidly in response to climate change. That's not so, Raina says.

suggesting the likelihood of the glaciers melting was "very high". The IPCC defines this as having a probability of greater than 90%"

Hasnain has since admitted that the claim was "speculation" and was not supported by any formal research

Preliminary mass balance values for the observation period 2007/08 have been reported now from more than 90 glaciers worldwide. The mass balance statistics (Table 1) are calculated based on all reported values as well as on the data from the 30 reference glaciers in 9 mountain ranges (Table 2) with continuous observation series back to 1980.

The average mass balance of the glaciers with available long-term observation series around the world continues to decrease, with tentative figures indicating a further thickness reduction of 0.5 metres water equivalent (m w.e.) during the hydrological year 2007/08. The new data continues the global trend in strong ice loss over the past few decades and brings the cumulative average thickness loss of the reference glaciers since 1980 at about 12 m w.e. (see Figures 1 and 2). All so far reported mass balance values, given in Table 3, are tentative.

Verdens gletchere fortsætter med at smelte.

Dagens foto fra MODIS rammer sagens kerne meget godt... tydelig afsmeltning på sydskråningerne i hele Himalaya

Manglende kildekritik/selvkritik i en International Institution skal man lede længe efter !!!

...blot se alle disse "Gates" nævnt i dette forum

Britisk Greenpeace beder formanden for IPCC om at træde tilbage, for at genvinde panelets troværdighed efter fejlen angående for hurtig afsmeltning på Himalaya.

Så her er nok en sjælden sag, hvor skeptikerne er enige med Greenpeace.

Men jeg synes måske, at det er lidt for voldsomt, når det er en enkelt fejl, som ikke er afgørende, og fejlen tilmed er erkendt og rettet..?

the key factor affecting their advance or retreat is the amount of debris – rocks and mud – strewn on their surface, not the general nature of climate change.

Glaciers surrounded by high mountains and covered with more than two centimetres of debris are protected from melting.

"Our study shows that there is no uniform response of Himalayan glaciers to climate change and highlights the importance of debris cover for understanding glacier retreat, an effect that has so far been neglected in predictions of future water availability or global sea level," the authors concluded.
