Faulty figures but glaciers still melting fast
(Aerial view, Greenland 2009)
The latest report by the World Glacier Monitoring Service says glaciers around the world are melting so fast that many will disappear by the middle of this century.
The organisation’s results come from monitoring in nine mountain ranges on four continents.
Unfortunately, quite a few people will probably be sceptical about the news after the revelation that a figure in the 2007 IPCC report warning of a “very high” risk that Himalayan glaciers could disappear by 2035 was false. This mistake has done a huge amount of damage. It has shaken people’s trust in the reliability of the scientific monitoring and peer reviewing process and provided more ammunition for the “climate sceptics”.
I had the chance to talk to one of the IPCC lead authors, Professor Adil Najam, born in Pakistan, now Professor at Boston University. He was taken by surprise when the mistake was revealed while he was on a lecture tour in Germany.
I’d like to quote him on this issue here:
It’s a bad mistake and a matter of serious concern, he says, because it questions climate and shakes people’s confidence in science. Coming from South Asia, Pakistan, which depend on the glaciers of the Himalaysa for their existence, the Professor says, “I am happy they were wrong… But science and the IPCC need to be much more careful, because climate science is happening in the public view.” He says allowing scientific details to dominate the headlines is detracting attention from the necessary process of accepting climate change is happening and pushing political action to help countries adapt.
There was apparently a kind of “Chinese whispers” game approach to the communication of the worrying Himalayan figure. It was quoted by a journalist, who had interviewed an expert (who says he was misquoted), and WWF, an organisation I normally respect for their thoroughness and professionality, took it over from there, and then it found its way into the report.
Let me quote Prof. Najam again: “The IPCC needs to be more rigorous. But one mistake should not sully all the very clear data”. This is the crux of the matter. Mistakes happen. This was not a deliberate exaggeration but an “honest mistake”, the Professor says. And he is convinced the data we have is worrying enough without anyone having to exaggerate anything.
The World Glacier Monitoring figures would seem to confirm that. The most vulnerable glaciers are not in the Himalayas but lower mountain ranges like the Alps or the Pyrenees in Europe, in Africa, parts of the Andes in South and Central America, and the Rockies in North America.
The WGMS figures show glacier melting is less extreme than in the last couple of years, but that the important 10-year trend show an unbroken acceleration in melting.
Somehow this has not made as many headlines as the IPCC mistake.
Copenhagen, Bonn, Mexico
Well, they didn’t do it. The EU is sticking to its 20% by 2020 figure. They could do 30%, but only will if others take more action. So much for being a leader.
UN climate chief Yvo de Boer held his first press conference since Copenhagen this week. It can’t be easy to keep going in the face of the Copenhagen fiasco. Of course he has to try to stay optimistic about the process continuing in Bonn this summer and Mexico towards the end of the year. But bearing in mind the US administration is in a even more difficult position after losing the Senate majority it will need to pass a climate bill, it’s hard to see where the impetus is going to come from.
Follow the leader?
The question is who is the leader, in the crusade to avert a climate catastrophe? (I know, sounds a bit melodramatic, but…)
Today WWF is calling on the EU to push ahead and set a firm goal of a 30% reduction by 2020 instead of 20%. (There is a meeting of EU reps in Brussels to discuss this on Wednesday).
WWF says this would give the EU the leading position it seeks. If it sticks to its position of only going up from 20 to 30% if other countries also make some concessions, the leadership claim would have to lie elsewhere, says WWF. Seems logical.
On the “climate change calendar”, January 31st is an interesting deadline. The agreement drawn up in Copenhagen includes a list where countries are supposed to enter their planned emissions reduction targets by that date.
Don’t get your hopes up too much – but it’s a date to watch.
Alarming rise in Arctic methane emissions
Sound familiar? Ice-blog readers will remember methane is more than 20 times as powerful as CO2 as a greenhouse gas, and that scientists in the Arctic are measuring the extent of methane emissions from melting permafrost.
There are billions of tonnes of methane captured in the Arctic soil. As temperatures rise and the permafrost melts, more methane is released. It increases the greenhouse effect further, resulting in a “feedback loop”, with the increased warming melting more permafrost and releasing even more methane.
Zackenberg station in Greenland, which I visited this year, is one of the Arctic stations measuring methane. If you haven’t heard the programme I made including interviews with Prof. Morten Rasch, who heads the Greenland environment monitoring programme, it’s available under the “climate” banner on the right of DW’s environment page. There’s also a photo gallery with brief texts if you don’t have the time to listen to the full feature.
Climate Monitoring in Arctic Greenland
Now a study presented in the journal Nature reports a massive rise in the amount of methane being released from the Arctic permafrost.

Guardian’s David Adam on rise in Arctic methane emissions
Although only 2% of global methane comes from the Arctic, the increase is highest in the Arctic, which is warming much faster than the rest of the planet.
The Guardian quotes Prof. Paul Palmer from Edinburgh University as saying the study “does not show the Arctic has passed a tipping point, but it should open people’s eyes. it shows there is a positive feedback and that higher temperatures bring higher emissions and faster warming”.

Happy Icy New Year
Happy New Year Ice Blog readers. I have been on holiday enjoying the winter weather in Germany and the UK. A lot of people are complaining about the cold and the bad road conditions and delays on planes and trains – but I for one am happy to have a real winter. What else would you expect from the ice-blogger? Some colleagues reckon this will save me an Arctic trip…
There is a lot of talking and joking as usual about whether the extreme winter conditions will undermine the acceptance that humankind is affecting the climate.
I was interested to read in the British press today that some British newspapers have even been taking the name of Professor Mojib Latif in vain, a respected climate expert at the Leibniz Institute of Kiel University Germany – whom I have interviewed several times. Two conservative papers apparently misinterpreted his research as signalling a switch from global warming to cooling. Fortunately (i.e. in the interests of the truth and no misrepresentation) today’s edition of The Guardian puts his research into context and quotes him as affirming his strong belief in man-made global warming.Prof Latif says the cold spell is short-term “weather” and not a cooling related to ocean cooling which he describes in his work. He also compares the complexity of the climate problem to Einstein’s theory of relativity and stresses the difficulty of presenting it accurately in the media. I’ll second that, but keep doing my best.
Before I stop for today I’d like to draw your attention to a comment posted by David Scrimgeour under the last entry.
He draws attention to the question of how clean technologies are going to be trasferred across borders, and what incentives there will be for example to German companies to invest in projects in potentially risky locations. Good question, David.
I personally think companies will only go into this if they know there is a market, and a market with a future. We need clear signals from governments – which we didn’t really get in Copenhagen – but we also need to draw companies’ attention to the finance experts who say it will ultimately be cheaper to work against global warming, and to all the studies which indicate the future lies with clean technology which does not put a burden on the climate. And of course companies are ultimately interested in making a profit. Look how some energy companies have realised fossil fuels are finite and are getting into alternative renewables – to secure their future.
Any other views on this?
