Last year the Warmers were defending the IPCC’s Fourth Assessment Report’s conclusion that the Himalayan glaciers would disappear by 2035. Oops, they then said, we meant 2350. Even so, we are being told that the glaciers were melting and so quickly that the people in Asia would be in big trouble when there was no more melt water. They believed that melting of Himalayan glacial ice was equivalent to 50 billion tons of water every year. But now a study ( lead scientist John Wahr and team) published in Nature tells that the Himalayan glaciers have lost no ice over the last decade. The measurements of global ice for this study were done using satellites. According to the report:
The reason for the radical reappraisal of ice melting in Asia is the different ways in which the current and previous studies were conducted. Until now, estimates of melt water loss for all the world’s 200,000 glaciers were based on extrapolations of data from a few hundred monitored on the ground. Those glaciers at lower altitudes are much easier for scientists to get to and so were more frequently included, but they were also more prone to melting.
The bias was particularly strong in Asia, said Wahr:
“Their extrapolation is really tough as only a handful of lower-altitude glaciers are monitored and there are thousands there very high up.”
Satellite data for the rest of the world’s glaciers were also measured and the team reported no changes in the melt rate.
Glaciers have been melting for the last 10,000 years. The question is really— is the present rate particularly unusual? This study certainly puts into question the warmers previous assertion that it is. Isn’t this just one more indication that there has been no statistically significant global warming over the past decade.
But whenever a study comes out like this, it is required to say—- nothing has changed, CO2 is still the problem. Prof Jonathan Bamber, the director of the Bristol Glaciology Centre said:
“The new data does not mean that concerns about climate change are overblown in any way. It means there is a much larger uncertainty in high mountain Asia than we thought. Taken globally all the observations of the Earth’s ice – permafrost, Arctic sea ice, snow cover and glaciers – are going in the same direction.
NOT OVERBLOWN????? (Just more uncertainty!!)
Professor Bamber also participated in an online Q and A session. He responded to a question from “On Earth” as follows:
OnEarth. For Antarctica and Greenland the results from this study are in very good agreement with most recent previous estimates of mass loss from the ice sheets so it doesn’t change our view of what these are doing.
I have always had a lot of respect for “most recent previous estimates..” what ever they are.
Are we to assume that much stress is being felt in Asian lands where the Himalayan ice melt is so important according to the IPCC? If there is no net change in total ice as the study tells us, does that mean there is a vastly reduced melt water flow? By the way, there are many studies that say the monsoons are the principal source of the water these Asian countries rely upon.
