The MRI

One of the main outputs of the MRI Global Commission was a set of mind maps related to themes that themselves emerged at the Perth Conference in September 2010. These mind maps record the thoughts and ideas of Commission members about how the MRI should pursued these themes in the future. One of my main tasks since the Commission meeting has been to translate these thoughts and ideas is more concrete project ideas that the community could pursue and the the MRI Coordination Office could support. While these proposals hardly rank as state secrets, we are not disseminating them widely but have rather asked Commission members for their review first.  If you, the reader, are interested in putting some effort into designing these future "Concerted Efforts" then send us a message via the website.

Soon after London, a select group of scholars from around the world convened at the Park Hotel in Asechi to participate in the IGBP/MRI Synthesis Workshop on Changing Mountain Cryosphere and its Downstream Impacts. This workshop lead to a commitment by Bodo Bookhagen and Ray Bradley to co-edit a synthesis paper with help from Wouter Buytaert, Bryan Mark and Sandy Milner. We expect to see this synthesis paper soon with a Policy Brief for IGBP later in the summer.

As MRI has two more Synthesis Workshops this year (one next week in Colorado and one in September in Switzerland) it is important to critique how we run the workshops. My observations from Aeschi:

1) It always takes longer than you think.  We programmed 15 minutes for talks but participants spent at least that much time again in discussion after the talks. This was time well spent re: the objectives of the meeting but of course put us way off schedule. We recovered somewhat by halting the presentations earlier than foreseen on day 1 (and moving the rest of the presentations to day 2) and using the rest of the day discussing the lessons learned from the talks given on day 1.


2)  Groups cannot produce outlines. Outlines must be proposed by one/two persons and revised by the group.   We started the meeting with only very rough outline. We then spent most of the meeting  discussing what needed to be covered in the outline but in the end it was simply impossible for the group to write an outline.

Two people with two "advisors" worked until midnight on the second day to produce the outline based on all the input given be others. The "two people" also became the two lead authors. 

I don't assert that we wasted effort over the first two days of the meeting, but I would assert that it would have been much easier if we had had a more complete outline at the outset of the meeting and had then related each presentation to the outline: did presentation X cause us to change the outline and how?

The alternative argument is that one would not get ownership of the outline and the subsequent writing work if the participants did not feel that they were the originators of the outline.  This is likely true, in which case, see 1) above in spades!

3) A strict outline approach based on assertions is essential to laying the foundation for writing.

The three days we had in Aeschi were not sufficient to get to the writing (see 1 again). Nonetheless the writing will not be very hard because we will have a well-annotated outline, in which each line is an assertion that will be "proved" by points beneath it. The outline does not consist of "topics" because a topic is not a message, and an article is fundamentally about communicating a set of messages.  It is surprisingly difficult to get people to "say what they mean". They tend to want to say "what they are speaking about" so one must get them passed that to get at  the real messages.   So for instance when people have said "hydrographs under climate change" we have had to push them to get assertions "hydrographs in the future will show more pronounced seasonality" and so on.

Once people know what points they are supposed to be supporting or proving, writing is easy.

4) Ownership must move from the organizers to the participants. Toward the end of the meeting I have made myself scarce as, despite my strong feelings about what should be in the document, I will not be writing it, and so shouldn't have power over the content. The content has to be that of the participants.

I am sure that I will have yet more observations as a result of the Building Resilience Synthesis Workshop next week.

The MRI

This is what my wife calls "repurposing": I wrote this for the IHDP newsletter so I might as well post it here first.

Mountains as Arenas for Adaptation to Global Change

 

The global change in mountains research community, which in the past has often emphasized biogeophysical aspects of global change, focused squarely on institutional arrangements in its session at the PuP Conference, Mountains as arenas for adaptation to global change. The session organizers included UNESCO, the Mountain Research Initiative (MRI), the University of Highlands and Islands (UK), the University of Bern (CH) and Makerere University (UG). The session. The presenters and their abstracts can be found on the PuP Conference site. The MRI has made available recordings of the slides and the speakers' talks through its website .

 

Martin Price started the session by highlighting the utility of Biosphere Reserves as sites for experimentation on adaptation to global change, as the concept of Biosphere Reserves includes at its core both human use of the environment and research. Bob Nakileza and Willem Ferguson described transboundary conservation areas in the mountain regions of Africa similarly as sites for research on adaptation. Stephan Rist and Bishnu Ray Upreti looked outside government reserve boundaries at common property regimes and reported on pre-requisites for the expansion of such regimes. Jörg Balsiger with a host of co-authors reviewed a wide range of regional governance arrangements in mountains from NGO alliances to treaty organizations as potential adaptive mechanisms. Finally Christian Huggel and his co-authors examined the mechanisms by which scientific expertise can inform adaptation in mountain regions.

 

The session showed a wide range of institutional arrangements, of which many if not most could be seen as potentially adaptive. The very diversity of arrangements is itself an interesting research topic, but in any event, the inventory is very far from complete and needs to be pursued further.

 

The research community needs as well to address the performance and effectiveness of these institutional arrangements as adaptive mechanisms. These institutional arrangements all have idiosyncratic origins and are thus not simply different responses to the same demand, in the case for adaptation to global change, but in fact are responses to a great variety of different expectations. Thus we must disentangle their performance relative to their avowed missions from that related to adaptation to global change.

 

Finally and in keeping with the transdisciplinary thrust of the PuP Conference, research certainly has a role to play in the conscious development of new institutional arrangements focused on adaptation to global change, as opposed to the more academic project of assessing the utility of existing arrangements in a new context. But such research must take seriously engagement with existing network of authority to surmount its own preconceptions and to achieve true co-production of knowledge.

______________

Mountain Research Initiative Global Commission

 

Thirty-three researchers from five continents, and from political science to climatology met together as the Mountain Research Initiative Global Commission at Imperial College on 30 March 2012, the day after the PuP Conference, to incorporate lessons learned from the Conference and to chart new directions for the Initiative.

 

Prominent among the lessons learned at the Conference was the on-going consolidation within global change research community into a single project, Future Earth. This consolidation has many origins and implications, but on the face of it, MRI is well aligned with the motivations behind this new project. MRI's objectives have always included one on the provision of useful knowledge to policy and practice, something that is now central to Future Earth. Beyond that, MRI's emphasis on interdisciplinary research within the context of a kind of landscape fits very well the announced objective of more "integrated" research. While other GC research programs have pronounced disciplinary roots, MRI has from the beginning espoused a whole system approach. While espousing and conducting are two different things, but at least our community has a place-based focus that provides a unifying context for our disciplinary pursuits. Finally, MRI has promoted "real projects in real places" for years, principally through the development of regional networks to complement the Global Commission. Thus we are several steps closer than many other projects to incorporating stakeholders and "co-producing" of knowledge. But we are not yet there.

 

As for new directions, the Commission discussed ten different themes that emerged from our community's last major conference, Global Change and the World's Mountains, held in Perth in September 2010:

· Mountains in the Global South

· Nature and Trajectory of Ecological Systems under Global Change

· Nature of Institutions and Social Systems and their Interactions with Ecological Systems

· Nature of Global Social Drivers

· Long-Term Mountain Observing Systems

· Ecosystem Services

· Human Agency in the Mountains

· Communication

· Human Presence in the Mountains

· Integrated Analysis and Modeling for Land Sustainability

 

The brainstorming at the meeting was extremely productive and will lead to specific propositions for "Concerted Effort" by the global change in mountains community in the next five years.

The MRI

Before I launch into more ruminations about Planet Under Pressure, I want to highlight some data. First. I tweeted extensively during the Conference. You can find those tweets under my Twitter name, MRIDIR, or under the hashtag #planetconf. I have been reviewing the conference today, a week later, and the tweets are a great record for me. I recommend that you try tweeting at your next conference, if only as a good way of recalling what happened.

And I suggest that you review some of the recording plenary talks. These are available here.

For the life of me, I can't understand why the organizers didn't record the speakers' slides along with their speeches! I's clear to me that MRI knows how to do this better than Elsevier!

On day 1 you should check out the talks by Diane Liverman and Will Steffens, talks that I mention in my earlier post. On day 2 Yves de Boer' is quite good, and during the panel discussion the business member, Keith Clarke, seemed particularly lucid. In general the business people at the conference seemed much less confused about social process and the ways forward than did the scientists.

I strongly recommend that you watch the plenaries on day 3, particularly the first by Richard Wilkinson, and the third by Laurence Tubiana, as well as the panel discussion led by Andy Revkin, formerly of the NYTimes. These may have been the best talks of the conference.

Finally on day 4, Johan Rockstrum's description of the new Future Earth consortium is very good. Richard Norgaard also spoke on day 4 and his video is under Parallel Sessions.

So what did I get out of all this? I was struck by the endless repetition of "need for new governance" with very little analysis of how to get there or even why we need to get there, other than the obvious observation that we don't seem to be approaching sustainable development very quickly, and in particularly have largely failed to address anthropogenic climate change. Laurence Tubiana said it well in her talk: in the 40 years since Stockholm 1972 (which is pretty much my entire professional life, and so I take this personally), sustainable development has been useful only as a diagnostic measure and has failed utterly to provide pathways toward its achievement.

To me the central question is "why?" Whenever I say this, there is a cacophony of responses. My soixante-huitard cousin harangues corporations. Andy Revkin talks about the scale of the problem exceeding our culture's grasp. Others talk about the need to change consciousness and so on. All of these may be true to some extent, but the fact is that the global change social science community has not examined this question as the social science question that it really is.

I do not delude myself into thinking that this is a trivial project nor that the data needed are easily available, but we must first see the question itself as something worthy of study, not just speculation and anecdote. As a result of this failure the community flails about, lurching from one mantra ("learning societies", "communication", "transdisciplinarity") to another without the benefit of evidence. (This is not entirely true as IGEC did a decent job and when Oran Young speaks it is still worth listening. Nonetheless I don't think that they went far enough into the dynamics of change.)

For me the problem takes almost crystalline form when we speak of "internalizing externalities". Numerous people correctly diagnosed our predicament as a market failure: that the full costs of our activities, particularly our consumption of fossil carbon energy, are not included in the costs of the goods and services that we buy. I suspect that few would contest that if these externalities were internalized, the market would work efficiently to reduce if not eliminate them. I think Richard Norgaard clearly said as much, that markets work well within the context of the incentives that underlie them. Such an approach is completely congruent with the prevailing market ideology of the world, and simply requires "getting the price right". And there are many "revenue neutral" options by which higher prices for fossil carbon (and other environmental damages) are offset by lower income taxes, so that one creates a price signal without necessarily changing the overall economic situation of households and firms. Yet for all the options that exist we have systematically failed to do so.

The response of many in the conference is then to promote changes in consciousness: less consumption, gross national happiness instead of product, etc. I see much merit in these idea, yet I fail to understand how they are easier to achieve - a quasi-religious conversion for billions of people - than simply getting the price of coal and oil to include their full costs in the world's commodity markets. I suspect those advocates might answer is that we would need this change in consciousness in order to change the political economy that sets world energy prices. While I don't know if I agree with that statement either, it at least embodies a hypothesis about the force and structures that lead to social change (or the maintenance of the status quo). We should treat such an implication as a hypothesis to examine, one of many that that global change social science should explore!

Andy Revkin said at one point that he doubted that the international climate negotiations would have succeeded even if there hadn't been a deliberate campaign by special interests to discredit the science. This is an experiment I dearly wished we could run: what would the world be like if there hadn't been such a campaign? Would we in fact have been able to stay with a 2°C warming instead of a 3-4°C warming? Some points in history are critical, where taking one route closes off forever other options. It is painful of course to recognize that we could have had a much better world if the "merchants of doubt" had not weighed so heavily on our political system. I fear that in the past 20 years we have indeed missed the turnoff to a better world, and that while we shouldn't give up, the world that we could've achieved is no longer available to us. Discounting the role of disinformation makes that miss marginally more palatable: maybe we couldn't have made that turn anyway, not because of a conspiracy but because the larger culture was in the way. However I doubt that assessment, and would like to focus the light of critical inquiry on the question.

There is of course much more to understand than just the role of well-financed interest groups. While they are undoubtedly important, and maybe more important than we generally believe, they are nonetheless part of a much larger process of social change, or more grandiloquently, human development. It is this system, the human equivalent of a coupled ocean-land surface- atmosphere model, that we lack. Yet without a clearer delineation of the structure and function of this system, all proposals for how science should interact with society are fundamentally anecdotal. While they are possibly true and might be "win-win", would any of us accept such anecdotes about oceans or atmosphere or the land surface without proof?

The MRI

Upon first entering the huge ExCel Center (more like the Shanghai combination airport and train station!) I not surprisingly bumped into a bunch on familiar people: Dave Schimel, Dennis Ojima, Ray Bradley, Prakash Tiwari and his wife Bhagwati, Chad Dear, Jeremy Littell, Jörg Balsiger, who else am I forgetting. It is gratifying to see that some of the mountain community is here.

Technically the conference is close but not equal to the AGU. The hall has wireless everywhere but very few power outlets, so you can tweet for awhile but soon power management becomes an issue. The organizers are streaming the plenary talks, and have established two-way communication with remote sites, so that observers at distant locations can send in questions via SMS or Twitter. The website allows some searching but if you want to find out who is speaking about mountains, you can only search the pdf of poster title, not session presentations. The AGU supports searches much better!

The talks: the first two by Diane Liverman and Will Steffens, focusing respectively on drivers of change and responses by the earth system were excellent and I hope that we can eventually provide a link on our website to either their ppts or to video stream put out by the conference. The main points here were that the drivers, principally population growth, GHG intensity and land use are still increasing but their rate of change is dropping. Most interesting statistic from Liverman: since 1950, average child/woman global has dropped from around 5 to around 2.5. This highlights the central role that women play in global change via their fertility. (Of course, as a husband and a father of three women I know that women also run the rest of the world too!). To be clear, LIverman did not say that GHG emissions were bending lower as we all know that they are not, but rather that GHG intensity has declined significantly, so we can say that the situation could have been worse than it is. Finally she should a great slide about GHG emission by income level within one country (UK? US?) that clearly showed that the impact of the higher income deciles was 50- 100% greater than the poorer deciles.

All that said, Will Steffens pointed out that the physical indicators of the earth system (e.g. atmospheric CO2) do not show any such slowing of the rate of change. He emphasized complex systems and tipping points, discussing the ice sheets, the Amazon and Siberia permafrost as three important possible tipping points. The map he showed (which we have all seen before) shows Tibet as another potential tipping point, the only one that explicitly involves a mountain region. This could conceivably be an MRI Concerted Effort.

Sandra Diaz gave an overview of how the tree of life (an evolutionary view) and the web of life (the trophic view) are being pruned by humans. Not only are we losing branches of the tree but we are also lopping away the top-level consumers while jacking up the primary producers with nitrogen.

Anthony Giddens, a sociologist, addressed the state of humanity. Here again my unease with the community's inability to articulate a clear social science vision was exacerbated. Giddens focused largely on the unreality of international treaty negotiations and stressed much more action at multiple levels of governance. He discussed the need for a new politics of "utopian realism", a theme that is well put, but once again he failed to address how one creates such a politics, and did not sketch how a more serious social science research agenda could lay the basis for such an approach. Nor did he offer any insights about economics and markets, something the Watson notes - "must get the economics right" - but similarly failed to articulate as a program. ON the light rail last night coming back for an incredible Indian dinner in London, Jörg Balsiger said that all this has been done already by others not present. We as a research community need to find that work and elevate it.

I had a similar problem with the panel discussion of eminent folks, not one of whom said, in reply to "What is one thing that you would think would lead to progress?", increase the market cost of fossil carbon. And it was not as if what they did say was easier or more likely to occur ("more transdisciplinary science", etc., etc.). I figure that if you are free to suggest things that plausible but nonetheless difficult, raising the price of fossil C would be at the top of the list!  The social science question is thus "since such a change would be both biophysically effective and would fit with the current ideology of market economics, why hasn't it happened?"

The MRI

What themes emerged at the AGU 2011 meeting that the MRI community might want to follow up with a Synthesis Workshop, or with a new category of activity that I'll just call a Concerted Effort?

Treeline appeared in many talks and posters, perhaps not surprisingly as Session B12B focused on treelines! I particularly liked W.K. Smith's talk in which he addressed how high elevation treeline environments differed from arctic or antarctic treeline environments, with for instance much higher radiation loads and much lower partial pressures. I noted shortly after the AGU that a recent paper by Malanson et al. in JAAAR proposed next steps in treeline research, so perhaps we don't need a Synthesis Workshop  but rather a Concerted Effort to pursue the lines of inquiry laid out by George, Lynn and Co.  A treeline effort modeled on MIREN(the mountains invasive network with standard protocols, etc.)  might be a viable option.

Many people reported on the use of smart sensor networks. When I asked if there were any platform that supported dialogue among developers and users of such sensor networks, no one seemed to know of any. So we have a very promising approach being developed by many different labs around the world with little interaction. Hmmm, this sounds to me like a good topic for a platform hosted by MRI.

Himalayan glaciers were also the topic of many different projects but it appeared to me that the projects weren't conferring with each other. There were projects funded by USAID, by NASA, by the EU and so on. And there will certainly be a number of papers that appear in the near future that attempt to fill the gap created by the IPCC AR4 gaffe. Still I wonder if a workshop where all the researchers could confront the data and analyses of others would not be a useful adjunct to the appearance of several disconnected summary papers in different journals. The point would not be to eliminate competition or even to seek consensus, but rather to accelerate the process of review and critique.

High resolution analyses and models of mountain meteorology also fascinated me. The role of aerosols in the form of snow, how clouds formed over mountainous islands, the development of jets that impede circulation: it seems that we are still learning quite a lot about the basic mechanisms of mountain meteorology. As climate change occurs physically through changes in these processes, a better understanding of them,  and especially of how changes in forcing will alter them seems like the most effective way to improve our forecasts of climate change.

The MRI Coordination Office has launched a call for new ideas for Synthesis Workshops, some of which might actually be the basis for what I am calling Concerted Efforts. If you want to propose something, click here!

American Geophysical Union Fall Meeting 2011: Part 1

The MRI

I wished that I had a dime for every time I heard people complain about how big the AGU meeting has grown! It is an enormous meeting: the number of participants this year was rumored to be around 22,000 people. Moscone South, the venue for the poster sessions, stretches one entire city block so that if you forget something at one end and remember it only at the other end, you are in for a hike back to retrieve your stuff! And shuttling back and forth between Moscone South and Moscone West, where the sessions are held, became a bit like a salmon run with hundreds of researchers streaming from one venue to the other. It was hard to advance if you are going against the flow.

But it is the very size of the AGU that makes it such a useful meeting. While not all the world's earth science researchers attend, a significant fraction do, including very strong representations from East Asia. And the AGU meeting management provides very good tools for navigating the 12,000 posters and 6,000 invited presentations.

I found so much relevant material at the AGU meeting that I have decided to break this blog entry into two parts. This first part will explain the informational resources that I have brought back from the meeting and highlight some of the talks that caught my attention. The second will explore some of themes that I saw emerging from the conference as relevant to MRI.

 

Informational Resources

 

The AGU Scientific Program webpage appears to be public so that you can search the program and create an itinerary (complete with abstracts) as I did (see below) even if you were not registered to attend.

 

In addition, poster presenters were encouraged to submit their posters to an "ePosters" site. Thus if you know the session code for the poster (and if the presenters uploaded their poster to the site, which alas many did not), one can download the poster! For instance the very first poster in my itinerary, C11B-0674. Glacier Surge-like signals detected by SAR-based technique in West Kunlun Shan, NW Tibet T. Yasuda; M. Furuya, has been uploaded to the site. By inserting the code "C11B-0674", I can download the poster itself.

 

Finally, the AGU has finally begun to record some of the presentations and has made them available via a Sessions on Demand button.  The AGU recorded numerous Union sessions and plenary lectures over the five days of the meeting. I suggest that you look at all five days to see what might be of interest to you. I particularly suggest the sessions GC43G Stephen Schneider session and the GC43H session on the history of global warming, both on 8 December 2011.

 

What exactly did I do? I searched the program using keywords such as "mountain", "Sierra", "Himalaya", "Tibet", and so on. After several iterations, I arrived at a nearly feasible itinerary focused on mountain-related topics, which runs to 254 pages and 18.3 MB. This itinerary kept me shuttling back and forth between sessions and posters for the whole time that I was there. I was extremely pleased with this modus operandi as I felt like I was able to focus right in on the most relevant work presented at the meeting. While I was not present on Friday,  I included Friday in my itinerary document so that the full five days were searched.

 

How can you use this mountain-focused itinerary of posters and papers? If you browse the first pages of the itinerary you will find the titles of papers and posters by session. Yes, there are 27 pages to this section of the document but as the papers and posters are organized by session title, you should be able to see quickly those that are of interest to you.

To see the abstract of any of the posters or papers listed there, simply search the rest of the document for the name of the first author and you will eventually find the abstract.

Papers and posters that made an impression on me


B12B-01. Mechanisms of Alpine Treeline Stability (Invited) W.K. Smith; G. Wieser; F. Holtmeier

I am always taken by papers that explain something at one level by mechanisms at another. Bill Smith assessed treeline dynamics by looking first at seeding survival, then at growth of seedling to tree stature and finally the facilitation of survival and growth by the presence of existing vegetation. Seedling survival was a question not just of carbon acquisition under low temperatures, high radiation loads and water stress but also of the processing of that carbon into plant structures. Snow played an important role is protecting seedlings and young trees but also presented physical challenges, especially abrasion, to growth above the snow layer into tree form. Finally, the presence of other plants greatly influenced the success of plants moving from one life stage to the next, a point also made by Lara Kueppers in one of her several papers or posters on the Alpine Treeline Warming Experiment on Niwot Ridge (though I can't seem to find mention of it in the abstracts). Smith emphasized that from an ecophysiological point of view, high elevations differ considerably from low-elevation polar environments in at least two ways - very high incoming radiation which often leads to photoinhibition of carbon processing, and very low partial pressures of CO2 with large impacts of fluxes. These two points seem directly relevant to the "why are mountains different" theme that was proposed by Mark Williams and Dave Schimel in Perth last year.


C23F-03. Mountain front precipitation accumulation over a 3300m elevation gradient from scanning LiDAR snow depth and in-situ instrumental measurements, southern Sierra Nevada, California P.B. Kirchner; R.C. Bales; J. Flanagan; K.N. Musselman; N.P. Molotch

I am always on the lookout for papers that examine the relationship between elevation and precipitation. Pete Kirchner created a very high resolution dataset on spring snow depths from the difference between snow-on and snow-off LIDAR measures, and found three distinction relationships between snow depth and elevation: a steep relationship below 2100m where precipitation was frequently mixed rain and snow, a shallower but highly significant relationship above 2100m (in non-forested areas), and then a flat relationship but with great variance at high elevation where snow redistribution was dominant.

Related talks included Danny Marks who reported on trends and projections of the rain-snow transition line and its impacts on runoff, a poster by Anders looking at elevation- precipitation relationships from different mountain regions around the world, and another poster by Minders looking at the mechanisms for ascent-forced convective precipitation over a mountainous island in the Caribbean. Minder also gave a good paper on the mechanisms for a lowering of snow line as the rain-snow transition zone approached mountain fronts.

 

A23E-06. Representation of the Sierra Barrier Jet in 11 years of a high-resolution dynamical reanalysis downscaling M.R. Hughes; P.J. Neiman; E. Sukovich; F.M. Ralph

Just prior to Minder's paper on declining snow line, I listened to a fascinating talk about a low level jet that runs parallel to the Sierra Nevada in California. For years I lived in the foothills of the Sierra, and never did I suspect that a thousand feet above me was a river of air moving parallel to the crest that forced upward incoming Pacific moisture and thus initiated precipitation well before the mountains. Several other talks in this session examined the nature and the impacts of the jet. I wondered if such jets were features in other mountain ranges as well, such as the Himalaya, that block prevailing winds.

 

H24D-05. Widespread hillslope gullying on the southeastern Tibetan Plateau: Human or climate-change induced? (Invited) J.D. Pelletier; J. Quade; R. Goble; M. Aldenderfer

Having seen these gullies myself, I had to go to this talk, which concluded quite simply that the advent of pastoralism with a reduction in vegetation cover was insufficient in itself to initiate gullying, as gullying had not begun in earlier, drier periods when the vegetation cover had been previously reduced. The gullying required as well on-going and increasing precipitation of the late Holocene to push the landscape over a threshold. I like this line of inquiry as I think climate change impacts on geomorphology in mountains is not well researched.

 

GC32B-03. The Modification of Orographic Snow Growth Processes by Cloud Nucleating Aerosols (Invited) W.R. Cotton; S. Saleeby

I listened to Bill Cotton four years ago at a meeting that MRI recorded in Boulder CO . I found his talk quite interesting then and so I expected a good talk this time. I was not disappointed. Here he talked about how aerosols, which can come from pollution, changed the rate at which snow flakes form and fall, so much so that horizontal winds push the precipitation further downwind often for 10's of kilometers. In the area of the study (on the Continental Divide in Colorado) this horizontal shift in precipitation moved significant amounts of precipitation from the Colorado River Basin on the Pacific side of the Divide to the North Platte River on the Atlantic side. Thus aerosol pollution can change not only the amount but also the location of precipitation.

 

GC32B-04. Hydrometeorological Scales Interactions in the Andes and their Impact on the Amazon Climate (Invited) R. Avissar; D. Medvigy; R.L. Walko

This talk showed the importance of mountains to the climate of surrounding areas. These researchers use the Ocean-Land-Atmosphere Model, which, besides featuring these coupled elements, models the entire planet using a variable sized grid. It thus produces regional climate predictions from a single model with a very fine grid spacing in regions of interest and larger grid spacing over the rest of the globe. Here they demonstrated that if one did not model the topography of the Andes at a sufficiently fine scale, then predictions of the inter-annual variability of precipitation over the Amazon were incorrect. I would have liked to have heard exactly what about the topography was important in getting better predictions of precipitation over the Amazon, but a little more digging in ISI will probably lead me to the answer.

 

C33F-08. Past peak water in Peru’s Cordillera Blanca: diagnosing the demise of glacier influence on stream discharge M. Baraer; B.G. Mark; J.M. McKenzie

Michel Baraer participated as well in the MRI KCW on 4 Dec in Berkeley. His talk here reviewed the expected time course for stream discharge from basins in which glaciers are receding, that is, an initial increase in discharge due to the melting ice volume and then when the glaciers are considerably small a reduction in discharge. He then reviewed discharge data to show that "peak water" had already occurred in the Cordillera Blanca of Peru, and that stream discharge was now on the descending limb of the expected curve. Thus the Cordillera Blanca is now where other major "glacierized" basins, such as those in the Alps, Central Asia and the Himalayas, may be in the future.

 

GC34A-08. Non-linear feedbacks between climate change, hydrologic partitioning, plant available water, and carbon cycling in montane forests (Invited) P.D. Brooks; M.E. Litvak; A.A. Harpold; N.P. Molotch; J.C. McIntosh; P.A. Troch; X. Zapata

Paul Brook's talk was one of eight talks in the CIRMOUNT-organized session: GC34A. Climate Change and Drought: Climatic Water Deficit and Water Balance in Mountain Systems: Biophysics, Ecohydrology, and Impacts.  All the talks here revolved around the ecological importance of potential evapotranspiration, actual evapotranspiration, and the difference between the two, climatic water deficit. All of these measures integrate precipitation and energy over the annual cycle and so are more pertinent than total annual precip or mean annual temperature at explaining the distribution and abundance of organism. I recommend that you look at all the abstracts in this session.

Brook's talk focused on some of the mechanisms related to snow accumulation and melt that strongly influenced water availability to vegetation. These include sublimation of snow, which is strongly influenced by tree canopy cover, and the depth of early snow pack as it influences the depth of frost in the soil and the soil's subsequent porosity at the time of spring snow melt. Once again, factors that one might not suspect at first (e.g. the degree of tree canopy or the timing and depth of first snowfall) turn out to be very important in the ecohydrology of mountains. Only when we know these will we be able to project better the impact of future climate and land cover change.

 

C44A-04. Past and future glacier changes the western Nyainqentanglha Range on the Tibetan Plateau (Invited) T. Bolch; F. Chen; W. Yang; M. Buchroithner; E. Huintjes; S. Kang; A. Linsbauer; F. Maussion; F. Paul; C. Schneider; D. Scherer; T. Yao

Tobias Bolch of the University of Zürich gave several talks at the AGU, all of them excellent. One (C43A-02) focused on a summary of glacier trends over the entire Himalaya, a definitive statement of which is essential in the face of the erroneous statements in the IPCC AR4. This talk (C44A-04) highlighted a method to assess glacial area and volume over time that is applicable at the scale of an entire mountain range. The relevance and clarity of the question was matched by the scope and completeness of the answer, representing to me the best of what research can do.

 

GC13C-06. Hurricanes in a Warming Climate (Invited) K. Emanuel

One of the reasons to go to the AGU is to hear talks from people who have made important contributions to the climate change debate (or to other scientific questions, such as the origin of life), even if their contribution has nothing to do with mountains. Kerry Emanuel updated his findings on the growing intensity of Atlantic hurricanes. He presented an amazing map of historic tropical cyclone paths, which clearly showed that the Pacific Ocean has many more tropical cyclones than the Atlantic ( a similar image is here) and leads one to wonder why the media focuses so strongly on Atlantic hurricanes.  He noted that there is no climate change signal apparent in the intensity of Pacific cyclones, which seems to vary with ENSO. However the intensity of Atlantic hurricanes does show a climate change signal, a combination of warming sea surface temperatures coupled with a cooling tropical tropopause. He emphasized that the damage from cyclones is overwhelming associated with a few high-intensity storms so even a minor increase in intensity would have major impacts on damage.

Despite some unfortunate last minute cancellations due to family affairs and illness the MRI Synthesis Workshop on Urbanization in High Mountain Regions (1-5 November) was a great success. Prakash Tiwari and his wife, Bhagwati Joshi, did an excellent job as local hosts, setting us up in the best hotel in Nainital, the Manu Maharani, a decision not without some poignancy as such luxury hotels are a key element in the development of some mountain cities and are not without their share of controversies.

The activities that really get traction are almost never the activities that you plan for, but rather are those that you think up on the fly. I noticed this years ago when back in California, I worked at a very innovative program called the California Forest and Rangeland Resource Assessment Program. It was, as with many things Californian, way ahead of its time, staffed with bright people and equipped with state-of-the-art GIS technology.

Session titles are now available for the IGBP Congress in March 2012 with abstracts due on 19 August 2011.

It's worth a few minutes of your time to peruse the list of sessions. There should shortly be a session on mountains in that list, but there are already some quite interesting sessions. One that caught my eye was one on tipping points in social networks chaired by Andy Revkin and involving Google and BBC.  Such a session smacks of the real world of politics and perception, a topic that, while recognized as central to our issue, never seems to be explored well enough at these kinds of meetings.
