It is with a heavy heart that I write this first blog post since my holiday, catching up with the latest climate news. A piece by Alex Kirby of Climate News Network drews my attention to the fact that temperatures in Barrow, Alaska, one of the first places to feature on the Ice Blog when it was created in 2008, have risen by an astonishing 7°C in the last 34 years (looking at the average October temperature). As Alex Kirby puts it, “an increase that, on its own, makes a mockery of international efforts to prevent global temperatures from rising more than 2°C above their pre-industrial level”. We need more climate action

The Arctic on the UN agenda

To those of us who deal with the Arctic on a regular basis, the significance of the melting ice for the UN climate negotiations and vice versa is abundantly clear. But not everybody understands all the connections. A major media event like this week’s New York climate summit hosted by the UN Secretary General Ban Ki Moon in person was a fine chance to focus attention on the need to protect the Arctic. Greenpeace made good use of it, handing over a petition with six million signatures just ahead of the big event, and with hundreds of thousands gathered in New York for the Climate March.

It was timely in more ways than one, just as the latest sea ice figures were published to confirm the melting trend.

The petition calls for long-term protection of the Arctic, with the region warming more than twice as fast as the global average and opening the high north to shipping and commercial exploitation. Greenpeace and other groups are calling for a ban on oil exploration, which could endanger the fragile ecosystem. Experts also have safety concerns about increased shipping.

The UN Secretary General is presented with a six million signature petition calling for long term protection of the Arctic region. The delegation consists of Indigenous rights activist, youth leader and Saami politician Josefina Skerk, Margareta Malmgren-Koller, who has signed dozens of leaders up to Greenpeace’s Arctic Declaration policy proposal; Greenpeace Senior Political Advisor Neil Hamilton and Greenpeace International Executive Director Kumi Naidoo.

Commercial development versus environment

Earlier this month, a survey showed that 74% of people in 30 countries support the creation of a protected Arctic Sanctuary in the international waters surrounding the North Pole. The study was commissioned by Greenpeace and carried out by Canadian company, RIWI. Around the same time, the Arctic Council, which combines the Arctic states and indigenous peoples’ representatives, currently chaired by Canada, supported the founding of a new business grouping, the Arctic Economic Council. Its aim is to promote the commercial development of the Arctic region. I wrote about this here on the Ice Blog and on the DW website.

Global responsibility for the Arctic

The UN Secretary General accepted the Greenpeace petition saying:
“I receive this as a common commitment toward our common future, protecting our environment, not only in the Arctic, but all over the world.”

Ban Ki-moon said he would consider convening an international summit to discuss the issue of Arctic protection. He also expressed a desire to travel aboard one of the organisation’s  campaigning ships in the Arctic in the near future.

Greenpeace Executive Director Kumi Naidoo, who was part of the delegation, said: “The Arctic represents a defining test for those attending the summit in New York”.

He said leaders should bear in mind that concern for the rapid warming of the world was not consistent with planning oil and gas development in the melting Arctic.

The small delegation that met Ban Ki Moon included Indigenous rights activist and Saami politician Josefina Skerk, who last year trekked to the North Pole to declare the top of the world ‘the common heritage of everyone on earth’.
Skerk, a member of the Saami Parliament, said: “We, who want to continue living in the North, are gravely concerned about climate change and the destructive industries that are closing in. My people know and understand the Arctic, and it is changing in a manner, which threatens not just our survival, but the survival of people all over the world.”

Skerk said humans had created the crisis and had to take action to solve it.

“I urge the Arctic countries in particular to take a giant step up and I think the world needs to pay much closer attention to ensure that it happens. They might as well start here in New York.”

From Kiribati to Svalbard and New York

Melting ice especially from the Arctic Greenland ice sheet is raising sea levels around the globe, endangering low-lying areas. At the weekend, the President of Kiribati, Anote Tong, ended a Greenpeace-organized tour of glaciers in Norway’s Svalbard Archipelago. He said the trip to the Arctic ice had made a deep impression on him, which he would share with world leaders at the U.N. climate summit:

“It’s a very fascinating sight. In spite of that, what I feel very deeply is the sense of threat,” Tong said. “If all of that ice would disappear, it would end up eroding our shores.”

Kiribati is a group of 33 coral atolls located about halfway between Hawaii and Australia. Many of its atolls rise just a few feet above sea level.

In last year’s report by the Intergovernmental Panel on Climate Change (IPCC), experts concluded oceans could rise by as much as 1 meter (3.3 feet) by the end of this century if no action is taken to cut the greenhouse gas emissions causing global warming.

“It won’t take a lot of sea level rise to affect our islands,” Tong said. “We are already having problems.”

Sea ice minimum confirms melting trend

The New York summit coincides with the annual announcement of the minimum sea ice for the year, as the summer season comes to an end. The sea ice – in contrast to glaciers on land – does not influence global sea level, but is regarded as a key indicator of how climate change is affecting the region. This year the figure announced by the US National Snow and Ice Data Centre (NSIDC) was 5.01 million square kilometers. The figure is the sixth lowest extent since records began.

The minimum ever recorded at the North Pole was 3.29m sq km in 2012 – and the eight lowest years have been the last eight years.

Ice levels in the Arctic have recovered from their all-time low, but are still on a shrinking trend, said Julienne Stroeve of the National Snow and Ice Data Centre. ”We have been telling this story for a long time, and we are still telling it,” she said.

NSIDC records showed that, this year, ice momentarily dipped below 5million sq km to 4.98m on 16 September, but the official figure is taken from a five day average.

Satellite data shows that one part of the Laptev Sea was completely clear from sea ice for the first time this summer. One of the most important questions for climate scientists is how soon the Arctic will experience its first sea ice-free summer.

Rod Downie, head of WWF UK’s polar programme, said that this year’s new Arctic minimum should prompt new action from the leaders meeting in New York. He stressed the connection between the Arctic and weather conditions in other parts of the world:

“As David Cameron prepares to meet other global leaders at the UN climate change summit in New York, the increased frequency of extreme weather that is predicted for the UK as a result of a warming Arctic should serve as a reminder that we need urgent action now to tackle climate change,” he said.

The summit was a major PR event to draw attention to the need for urgent and substantial climate action. The accompanying protests around the globe show people are not happy with the slow pace of the climate talks and their governments’ efforts to reduce emissions. Of course there was little in the way of concrete pledges. Still, on the whole, I see it as a successful step on the way to a new climate agreement because it has put the spotlight on climate change at a time where international conflicts are dominating the news agenda.

UN Climate Chief on New York summit

Your Ice Blogger has been busy with the New York climate summit around the corner. I was delighted to read that Ban Ki Moon is considering a special Arctic summit and a trip on a Greenpeace Arctic mission vessel after receiving a petition to Save the Arctic. I am also hoping there will be some high-profile promises of climate action.

Meanwhile, here in Bonn, I talked to Christiana Figueres, the Executive Secretary of the UNFCCC (Climate Secretariat), which is based here in Bonn, just next door to my Deutsche Welle Office, before she left for New York.

UN climate chief Christiana Figueres

UN climate chief Christiana Figueres

She told me what she expects of this meeting, which is something different from the regular UN climate summits. She also told me why she was joining yesterday’s climate march.

Let me share some excerpts from the interview in writing here with you, and offer you a full length audio version of my talk to this very influential and passionate lady.


More on the climate summit and the Arctic here soon.

 Excerpts from my interview with Christiana Figueres:

Ice Blogger: Why do we need yet another climate summit?

The conferences we organize once a year have the purpose of moving towards a legally based agreement, scheduled to be adopted in Paris next year. In New York, nothing is going to be negotiated. It’s very much an attempt to blow wind into the sails of the formal process. It’s about raising political will and public awareness.  It is a powerful opportunity for the leaders of countries and corporations to come forward and say what each of them is going to do.

UN Secretary-General Ban Ki-moon has asked these leaders to bring bold announcements and actions to the summit. What do you expect to come out of it?

We will have a host of announcements from governments about what they are already doing and will undertake with respect to bringing down their own emissions and increasing the resilience that they need to incorporate into their planning and their infrastructure to deal with the variability and the vulnerability of climate change. From the private sector we expect the same: announcements as to how they are going to contribute to reduce emissions, either in their own operations or, even more interestingly, how they are going to be shifting their capital into low-carbon services and products to accelerate the global shift towards a low-carbon economy.

Are you expecting major announcements by the host country USA or a key player such as China?

Yes, we are expecting all countries to come forward and begin to put on the table what they will be able to contribute next year into a much more formal setting. But for that, the deadline is not until March 2015. What we expect is indications of what is possible. The fact is that most countries around the world are currently doing their homework and figuring out at a national scale what is financially, politically, economically and technically possible for them to do.

The summit is taking place in the USA, a key player in terms of emissions and a possible new climate agreement. Can hosting the summit there make a difference to US attitudes and policy?

The second term of President Obama has seen an accelerated and up-scaled engagement on climate change. The latest move of the Obama administration to ask the EPA (US Environmental Protection Agency) to come forward with regulations on power plants is probably the most ambitious action the US government has taken on climate change. We expect President Obama will be giving indications of how the United States is going to further build on those efforts. It is also very interesting that on US land, there will be the people’s climate march, just two days before the summit. That will show that there is, even in the United States, broad and deep public support for global climate policy making.

Do you think this kind of grassroots movement is what we need to take things forward?

I think it’s a very important component. I’m very grateful to the organizers of the march and to everyone who’s going to be at the march. I will be there, because it’s important to give a very strong message that it is not just the responsibility of governments or corporations, but rather there is also civil society responsibility here to make their awareness and concern felt, and encourage countries and companies to move towards low-carbon economies as soon as possible.

Some people say cities and regions should play a bigger role while governments struggle to negotiate a climate agreement?

Well it’s not an either or. Cities all around the world have already taken a very impressive lead. And we will hear from them. The mayors of hundreds of cities will be in New York, and the same goes for regions, whether it’s groups of countries or groups of municipalities. The optimization of climate action is going to come from the coherent integration of policy from the international level to the national to the local level.

Isn’t it difficult to arouse interest in an additional climate summit in the current world political situation with attention focused on conflicts in the Middle East, Ukraine and other places?

The whole week in New York will see much press attention to the summit. Not only because we will have hundreds of thousands of people on the street, not only because we will have hundreds of political leaders there, hundreds of corporations, but because they are all coming to New York for one very powerful reason. That is, climate change is now the biggest challenge that humanity has faced, certainly in this century. And there is growing awareness of this. There is already a lot of conflict around the world, around water scarcity, around migration, around food and security, and that is exacerbated by climate change. So if we want to prevent conflicts that will scale out of control, then we have to address climate change in a timely fashion.

The latest figures show greenhouse gas emissions are still rising. Scientists say the two degree target is virtually out of reach. What has to happen to bring about the kind of action we need to avert disastrous climate change?

Science has made it very clear: there is only one pathway that will allow us to stay under the maximum two degree maximum temperature increase which is the maximum temperature increase we could allow, and still maintain a more or less predictable climate for all populations around the world. So this summit and the formal processes which will occur in Peru at the end of this year and in France at the end of next year are three very important clarion calls to world leaders both public and private that time is running out. We still have the time to do it, but in order to avert the worst effects of climate change, we have to come to a global agreement by next year.

Coal, climate, cryosphere

Fossil fuel power plants are still on the increase – committed carbon emissions are rising fast. At first glance you might respond to that with “so what’s new”? Well, a study is new, which indicates that in spite of all the political rhetoric in a lot of places about switching to renewable energies and moving away from fossil fuels, we are building more fossil fuel power plants than ever before. Unsurprisingly, that is leading to an increase of carbon dioxide emissions, which is bad news for plans to keep global temperature rise below 2°Celsius. It is extremely bad news for those of concerned about the cryosphere and the increasing melt rates of Greenland and parts of Antarctica. The main problem, the authors tell us, is that we have already committed to huge emissions by investing in polluting technologies.

Steven Davis of the University of California, Irvine and Robert Socolow of Princeton University in the US, report in the journal Environmental Research Letters that existing power plants will emit 300 billion tons of additional carbon dioxide into the atmosphere during their lifetimes. In this century alone, emissions from these plants have grown by 4% per year.

The two scientists have already reported on the increasing costs of delay in phasing out fossil fuel sources of energy, notes Tim Radford of the Climate News Network. Thanks again to you people for drawing attention to the study. Their latest research looks at the steady future accumulation of carbon dioxide in the atmosphere from power stations.

“Despite international efforts to reduce CO2 emissions, total remaining commitments in the global power sector have not declined in a single year since 1950 and are in fact growing rapidly,” the report states.

Massive emissions already committed

Governments worldwide have in principle accepted that greenhouse gas emissions should be reduced and average global warming limited to a rise of 2°C.

At the current pace though, scientists have warned that the world is on track for at least 4° Celsius by the end of the century. That could mean drastic rises in sea levels and catastrophic drought in some areas of the world.

The shift from fossil fuels to renewables is not happening fast enough

“We are flying a plane that is missing a crucial dial on the instrument panel,” said Socolow. The needed dial would report committed emissions. Right now, as far as emissions are concerned, the only dial on our panel tells us about current emissions, not the emissions that capital investment will bring about in future years.”

In the latest study, scientists asked: once a power station is built, how much carbon dioxide will it emit, and for how long? They assumed a functioning lifetime of 40 years for a fossil fuel plant and then tallied the results.

The fossil fuel-burning stations built worldwide in 2012 alone will produce 19 billion tons of carbon dioxide over their lifetimes. The entire world production of the greenhouse gas from all of the world’s working fossil fuel power stations in 2012 was 14 billion tons.

“Far from solving the problem of climate change, we’re investing heavily in technologies that make the problem worse,” the experts stress.

The US and Europe between them account for 20% of committed emissions, but these commitments have been declining in recent years. Facilities in China and India account for 42% and 8% respectively of all committed future emissions, and these are rapidly growing in number. Two-thirds of emissions are from coal-burning stations ad the share from gas-fired stations had risen to 27% by 2012.

Fossil fuel wind-down not fast enough

Davis says more fossil fuel-burning facilities have to be retired than new ones built. “But worldwide we’ve built more coal-burning power plants in the past decade than in any previous decade, and closures of old plants aren’t keeping pace with this expansion”, he added.

According to Socolow, a high-carbon future is being locked in by the world’s capital investments: “current conventions for reporting data and presenting scenarios for future action need to give greater prominence to these investments,” he said.

The current draft of a summary report to the International Panel on Climate Change (IPCC) due to be released in November and viewed by the Times this week, warns of “severe, pervasive and irreversible impacts” unless carbon emissions are brought under control. The IPCC stresses that human-induced climate change will lead to the devastation of homes and property, a scarcity of food and water and human mass migration, as sea levels rise through warming temperatures and – alas – melting ice.

Human action speeds glacial melting

The Sermeq Kujualleq glacier discharges icebergs into the sea (I. Quaile, Ilulissat 2009)

It might sound like stating the obvious, but in fact it is not easy to find clear evidence that human behavior is behind the retreat of glaciers being monitored in different parts of the world. Hence my interest in a study just published in the journal Science.

The main problem is that it usually takes decades or even centuries for glaciers to adjust to climate change, says climate researcher Ben Marzeion from the Institute of Meteorology and Geophysics of the University of Innsbruck. He and his team of researchers have just published the results of a study for which they simulated glacier changes during the period from 1851 to 2010 in a model of glacier evolution. They used the recently established “Randolph Glacier Inventory” (RGI) of almost all glaciers worldwide to run the model, which included all glaciers outside Antarctica.

“Melting glaciers are an icon of anthropogenic climate change”, the authors say. However, they stress that the present-day glacier retreat is a mixed response to past and current natural climate variability and “current anthropogenic forcing”. Their modeling shows though that whereas only 25% of global glacier mass loss between 1851 and 2010 can be attributed to human-related causes, the fraction increases to around 69% looking at the period between 1991 and 2010. So human contribution to glacier mass loss is on the increase, the experts write.

Marzeion says the global retreat of glaciers observed today started around the middle of the 19th century at the end of the Little Ice Age, responding both to naturally caused climate change of past centuries (like solar variability), and to human-induced changes. Until now, the real extent of human contribution was unclear. The authors say their latest piece of work provides clear evidence of the human contribution.

Once more I am happy to refer to the Climate News Network, in this case to Tim Radford, for an easy-to-read summary of the main research results and the background. There is no doubt that glaciers are losing mass, retreating uphill and melting at a faster rate, says Radford. He refers to some Andes glaciers and the the Jakobshavn glacier in Greenland, or Sermeq Kujualleq as I prefer to call it, using the indigenous name. Ice Blog followers may remember my own trip to Greenland and that particular glacier. I have also written on the speeding of the melt there on the Ice Blog and on the DW website.

Radford also refers to ascertaining the melting of alpine glaciers by comparing historic paintings and other documentation with the current ice mass. That decline is something I have observed at first hand in Valais in Switzerland during regular visits over the past 30 years. Look out for a comparative photo gallery of my own pics, when I get time to put it together. Since most of the shots are from the pre-digital era, that will be a time-consuming task.

I also remember a trip to the Visitor Centre of the Begich Boggs glacier in Alaska in 2008. The glacier has already retreated so far you can’t see it at all from the Centre built specially for the purpose of viewing it.

The question until now was how much of all this was caused by natural developments and how much to changes in land use and the emission of greenhouse gases? The latest study supported, among others, by the Austrian Science Fund (FWF) and the research area Scientific Computing at the University of Innsbruck, has come up with some answers. Since the climate researchers were able to include different factors contributing to climate change in their model, they can differentiate between natural and anthropogenic influences on glacier mass loss

“While we keep factors such as solar variability and volcanic eruptions unchanged, we are able to modify land use changes and greenhouse gas emissions in our models,” says Ben Marzeion, who sums up the study: “In our data we find unambiguous evidence of anthropogenic contribution to glacier mass loss.”

As always, there is still need for further research – and a lot more monitoring. The scientists say the current observation data is insufficient in general to derive any clear results for specific regions, even though anthropogenic influence is detectable in a few regions such as North America and the Alps, where glaciers changes are particularly well documented.

With global glacier retreat contributing to rising sea-levels, changing seasonal water availability and increasing geo-hazards, the study’s conclusions should help put a little more pressure on the world’s decision-makers to get serious about emissions reductions.
