Merry Christmas & Happy New Year!

This year, particularly the last 6 months, I have been mostly off blogging. However, many things have happened for me and my company BLB and hopefully I'll be able to be more active online in 2013.

With this card I wish you all the best for the rest of this holiday and of course for 2013!

Women and Science

 Prime Minister Gro Harlem Brundtland, 1981

Being a woman and an astrophysicist is unfortunately still a rare combination, particularly in the Nordic countries. Women have held leading political positions for many years in Norway. Former Prime Minister Gro Harlem Brundtland, being the most prominent and influential one, lead the way acting as Minister of Environment in 1974-1979. Later in 1981, she became Norway's first female Prime Minister starting the process that resulted in what today is gender equality in Norwegian political representation.

In spite of this strong female representation within politics and in spite of decades with a steady increase of female students on all levels at the universities, we find very few women in top academic positions; as professors and institute leaders. Statistics from the Research Council of Norway also show that scientific projects/grants still are dominated by male leadership and participation.

Since I worked on recruiting women to science, technology and medicine back in the early 90ties, I'm sad to say not much has changed. The statistics are about the same, the same obviously wrong explanations are offered, all in all pretty much status quo. 

My own very subjective understanding of this landscape has not changed after I worked on recruiting women to underrepresented fields of science. It can be summarized in a very simple conclusion:  Life is not fair. It is a conclusion that makes it easier to act and maneuver in the battlefield; a battlefield where we all fight for the best possible position for ourselves. As long as you know what you are up against, it is easier to develop an effective strategy. 

There are disadvantages and advantages being a woman in the research community. For instance, as a woman you are highly visible and you will get a lof of attention. However, that visibility also means that all your mistakes, small or big, will be noticed.

Being a woman in science was the topic of a workshop led by Prof. Eli Hustad at the University of Agder in May 2012. Prof. Hustad wanted to establish a network that could help women succeed in the world of science. Her more specific goal was to initiate concrete projects and collaboration, literally right on the money.


And money was what I talked about as one of the invited keynote speakers. Having access to resources is key to success within academia as in business in general. My knowledge about the research system and particularly the different funding instruments were the main reasons for me being there. The title of my presentation was "Challenges and Opportunities for women in science: the role of social network. How to make good research applications: experiences from The Research Council of Norway and project applications".  You can find my presentation here and although it is mostly pictoral, there are some useful information to be found too.

Prof. Aurilla Aurelie Bechina Arntzen is an expert on automation, artifical intelligence and general information system management. Based on her extensive experience from leading and participating in EU-projects, she gave the audience good advice on how to succeed with research applications. After she had told us some sad statistical stories about women in science....

At the University of Agder they try to encourage women to enter the world of science - as politicians ask them to do. Mrs Ragnhild Lager, advisor on gender issues at the university, informed us about their strategy plan to increase the number of female academics.  I am not sure if I was surprised or not when she said that the plan has a specific number with respect to % of female academic employees, but not a specific time when they should reach this number. It is a fail with respect to generally being a good strategy plan, that is for sure. Deadlines are given in good plans. Just saying.

Then two ph.d students told us about their work; Soffi Westin is a ph.d student coming from a global enterprise combing her phd work on improving quality in engineering projects through Information Management, while maintaing parts of her work in and for the company Aker Solutions, and Karen Stendal brought us into a virtual world being used by people with reduced functionality in the real world. All pretty interesting presented in an entertaining fashion.


University of Agder was the youngest university in Norway until 2011. (University of Nordland was born 1. january 2011). The University of Agder received funds from Gender Balance in Research to organize the workhop.

It is always a pleasure visiting the deep south of Norway and I am happy to say I will return this month.

Venus, The Moon and Jupiter - triple conjunction time

Although I went for an evening walk about one day late for the actual alignment of the Moon, Venus and Jupiter, it still looked pretty spectacular. I've put together some footage I captured on my walk. You'll see the Sun sets before I turn to the Moon and planets. Venus below and Jupiter above the crescent Moon.



Since this recording the Moon has 'departed' from the scene leaving Venus and Jupiter shine alone. Well, there's alway all the rest of the Universe present of course. :-) If you want to know what else to expect from the skies this month you should check out Our Night Sky by Carolyn Collins Peterson over at Astrocast.TV.

You hear Prokofiev's Violin Sonata No 2 played by my niece the violinist Sarah-Erin Bye with David Meier, Germany on piano. See and hear the entire concerto here.

Climate & Classical

Here is finally a short introduction of the Climate & Classical performance. Most of the footage of nature is recorded on the countryside in Norway where I grew up and still live.

Enjoy! And do let me know if you would be interested in working with us setting up the performance.

Climate Change Rhetoric - Communicating Uncertainty

With time the details have become blurry, but I still remember the anxiety I felt the first semester as a student at the University of Oslo. When I made the decision to move from the comfort of my parent's home on the countryside to the big unknown city of Oslo I had no idea what to expect. The uncertainty felt almost complete; Oslo was an urban environment that I had hardly ever visited, I didn't know a soul and I had never been to an university in my entire life. All I knew was that I wanted to become an astrophysicist. I made a life-changing decision based on very little information.

Some of us are willing to take bigger risk than others. In certain situations we have to make decision without knowing how big the risk is. All though it can be wonderfully exciting not knowing, the professional risk takers such as extreme sport athletes, stock traders or astronauts spend lots of time and energy on analyzing risk. That implies getting an idea of the uncertainty of the available information.



As illustrated by Sir Edmund Hillary, the first to reach the top of Mt Everest, acknowledging that you do not have exact information is an important part of risk management. Credit background image of Mt Everest: ddanforth

My decision-making was a personal one that only had an impact on me, my family and perhaps my closest friends. Decisions are being made on all levels in society implicating individuals, nations, regions and in some areas a number of decisions influence the entire planet.

Decisions related to climate change are ultimately and collectively global. The Earth is such a complex system that most of us realize that we do not have an overview of the risk our planetary management represent. We know that our information contains lots of uncertainty. Decisions based on anticipations of how climate will change in the future is high-risk business.

At the coming Rio +20 United Nations Conference on Sustainable Development (20-22 June 2012) conference, our world leaders will make yet another attempt to agree on decisions related to our climate. Already 20 years ago, at the first Rio conference, further scientific knowledge and Earth observations were encouraged (Agenda 21) because that would improve the decision-making process. In the language of policy-maker that is 'making informed decisions'.

I will take a closer look at how the uncertainty of this in-demand information about climate change has been communicated and I'll be bold enough to suggest some improvements. In order to provide you with a wider perspective of the subject I'll start with describing how uncertainty is being managed in a couple of related areas.

Communicating uncertainty of natural hazards

Daily, millions of decisions around the world are being made based on uncertain scientific information. Meteorological forecasts are good examples of such information. Take for example tornados; tornados are generally thought of as completely unpredictable, but modern site-specific forecasts are today able to keep people informed well ahead of a tornado and provide enough time for them to take shelter. These meteorological forecasts, be it the regular and daily weather forecasts, the occasional tornadoes or the seasonal hurricanes, all include estimates of uncertainty. Yet, we make all sorts of important to trivial decisions based on this information. While the current information is considered acceptable and actionable, scientists are relentlessly continuing their work on expanding our knowledge, reducing uncertainty as well as finding better ways of estimating and managing the uncertainty. It is all an integral part of operational services.

The author spoke with Prof. Seth Stein (Northwestern University, USA) at the European Science Foundation-COST High-Level Research Conference “Understanding Extreme Geohazards: The Science of the Disaster Risk Management Cycle.” November 2011. Prof. Stein articulates the need of communicating uncertainty connected to hazard maps.

Climate change is a natural hazard

Climate change is a slow natural hazard and as such in principle both easier and more difficult to manage than fast natural hazards like earthquakes, tsunamis, landslides and volcanic eruptions. It is easier because we have more time to prepare ourselves for the change and mitigate its effects. It is more difficult to manage because it is so slow its effects escape our attention and we do not feel the same urgency to act.

Although the disaster risk management system is well established, addressing uncertainty is in its infancy within the fast natural hazards community. (IUGG resolution 2010 and 2005?) Prof. Stein recommend that we accept that hazard maps are “living documents” that need to be continuously improved and updated. One way of improving the maps is to increasingly use empirical data suchusing a combination of statistical and empirical ( such as validation, and assimilation of Earth observation data) approaches in the production process. Concerning management of uncertainty in hazard maps, Prof. Stein points to the IPCC's systematic way of handling uncertainty and suggests a similar approach within his field of seismic hazards.

IPCC and uncertainty

Trying to look into the future development of climate, we use climate projections based on various climate models. These models and derived climate projections contains uncertainties. The IPCC addresses this issue in their guidelines for both AR3, AR4 and the latest for the coming AR5 were published 2010. However, not everybody find this satisfactory.

Climate scientist Prof. Judith Curry is voicing concerns about the way uncertainty is treated by climate scientists, in particular by the IPCC . She has written several articles on the subject arguing that the IPCC has oversimplified the issue of uncertainty in its Assessment Reports, which she warns can lead to misleading overconfidence. Curry suggests that a concerted effort by the IPCC is nescessary to identify better ways of framing the climate change problem including exploring and characterizing uncertainty. She also finds that we need to eliminate bias from the consensus building process itself. Members of the IPCC working groups have responded to Curry's suggestions and views and you'll find that the temperature of the scientific discussion is hot, making it exitingly interesting to follow. (Several links are at the end of this article if you are interested, for instance a special issue in the journal Climate Change published by Springer.)

Different kinds of uncertainty

Back in my early twenties, before I made my decision to become an astrophysicist and study in Oslo, I collected as much information as possible, but found almost nothing. I knew that I knew very little. In fact I knew that I would meet challenges that I did not even know existed, yet I made the decision. But I was prepared for the unknown uncertain future.

We all have a notion of what uncertainty is and have strategies to manage it. When we discuss uncertainty in a scientific context it is practical to distinguish between different kinds of uncertainty. We do not want to compare apples and pears. Take the Earth observations from space for instance. The processes to quality check, validate and calibrate are well defined and an integral part of the activity itself reducing the uncertainty both of the operations and the resulting observations. Meticulously designed and correctly performed experiments can be flawed just because of a malfunctioning cable, as we saw with the OPERA experiment at CERN. At a first glance the experiment seemed to have proven Einstein wrong and that it was possible to travel faster than light.

In addition to uncertainty related to human and instrumental errors we can group uncertainty in two categories: aleatory and epistemic. Epistemic uncertainty is associated with imperfections of knowledge, which may be reduced by further research and empirical investigation. Aleatory uncertainty is associated with inherent variability or randomness. When constructing climate models there will be epistemic uncertainty because we do not know if we have included all physical processes correctly, or all of them. Testing the climate models with observed data includes aleatory uncertainty.

Including information about uncertainty will definitely make the information more actionable for decision makers and then an important question is; how is uncertainty communicated outside the scientific community?

Climate change communication at American Geophysical Union (AGU) 2011

Communicating climate change is still a hot topic and I suspect will remain so in the foreseeable future. At the 2011 AGU Fall meeting the program was packed with presentations, workshops and other meetings addressing climate change. Although communicating the science of climate change is gaining attention, the rhetoric and general approach remain the same. The simplified message (in this rhetoric) is: we know the planet is in peril because of human activity and we need to act with great urgency. And fossil fuel is (the evil) to blame. I must admit I was a bit disappointed to see that even in the Town Hall meeting with the title “Directions in Climate Change Education and Communication” this same message was repeated – again and again. What is wrong with this rhetoric then?

Below you'll find a few more examples that show how the scientific community struggles to find ways to communicate scientific knowledge that include information about uncertainty in a way that is trusted, understood and accepted for decision-making.

The “Because I say so” argument

As a child I hated it when my parents tried to pull a “because I say so” argument on me. It just wasn't a valid argument, I thought. Unlike me, who respected my parent's authority, society does not even trust climate scientists, or any other experts, saying “because I say so”. Their authority is no longer recognized. This phenomena is illustrated by for instance the debate we had in connection with the so-called Climategate. Yet, the communication strategies often include arguments (rhetoric) like: 97 % of scientists agree that there is global warming. It doesn't matter what people we do not trust agree on. This authoritative “because I say so” rhetoric didn't work on me as a child nor does it work on our modern society. Whether we like the scientists loss of authority or not, it would be wise to develop a new rhetoric that takes this new reality into account.

Endorsing scientific facts by voting – IUGG and AGU

As a Norwegian delegate to the IUGG Council meeting in Perugia, Italy in 2007, I was asked to vote on a resolution concerning climate change The Urgency of addressing Climate Change. In this resolution it said: “ ...that human activities are the primary cause of the recent climate change...” with reference to the IPCC and other national and international bodies. It was a reinforcement and endorsement of the IPCC report by a body comprised of members with various background.

As a scientist I felt uncomfortable with this process, finding it to lack scientific foundation within the body I was a member of.

In its position statement Human Impact on Climate, AGU states: The Earth's climate is now clearly out of balance and is warming. That is a very bold statement approved by the AGU Council twice; in 2003 and 2007. The boldness in this particular statement lies in claiming that the climate is out of balance. Whereas claiming that the planet is warming can be supported by Earth observations, the balance question is highly speculative depending on modeling of the complex Earth system that are far from precise nor certain, and certainly cannot be supported by scientific proof or Earth observations for that matter. We can suspect and fear that the climate is out of balance, it is a reasonable hypothesis, but we cannot claim that this is a fact based on todays evidence. It is definitely not a matter that can be decided by voting.

As in the case with IUGG, the AGU Council is comprised of people with different background and competencies, voting for or against statements (hypotheses). Voting is not an element in a scientific method and therefore undermines the credibility of the entire scientific community.

Change of rhetoric

Rhetoric is the art of discourse, an art that aims to improve the facility of speakers or writers who attempt to inform, persuade, or motivate particular audiences in specific situations.

We are the most persuasive when we are found to be trustworthy and appeal to people's feelings. The current climate rhetoric might be efficient in a wake-up call phase. Al Gore with his “An inconvenient truth” wanted to scare us a bit and succeeded with that. As I already pointed out, the public no longer place the same trust in scientists as in earlier times. The scientific community need to work on re-establishing trust. The current rhetoric is also focusing too much on negative feelings or scaremongering. Even though we might find delight in being scared from time to time, it is not effective in the long run. We need to evoke more positive feelings in the population.

In his award winning documentary An Inconvenient Truth, Al Gore showed us what sea level rise would do to Manhatten, NY in USA. This unrealistic image can easily backfire when science based scenarios show much less dramatic effects.

Both the IUGG and IPCC do address uncertainty connected to climate change, but unfortunately they have not found a successful way of communicating it. By omitting or not fully inform about uncertainties, the messengers trustworthiness is at stake.

Reducing and managing uncertainty

Better access to and increased use of climate data will help reduce uncertainty and improve our understanding of climate change. Following recommendations from the UNFCC meetings, the Group of Earth Observation has worked since 2005 on implementing a Global Earth Observation System of Systems that will make data available in an interoperable way through a data portal.

Showing the carrot, hiding the whip.

In a positive environment it will be easier to communicate the uncertainty. Out starting point is more often than not, that the meteorologists do has best as they can.

Geolabel
In order to engage the science and technology communities in the development and use of GEO, GEO made a Science & Technology Roadmap. Among many activities in this roadmap we find the building a “GEO label” to recognise the scientific relevance, quality, acceptance and societal needs for activities in support of GEOSS. Labeling and certification are generally tools that we use to create trustworthiness and traceability. In this respect a GEO label can also function as a framework for managing uncertainty related to Earth observations

No matter how well we know the uncertainty connected to climate change or how well it is communicated to the various decision-makers, we as a society will continue to do exactly as I did when I made the choice of becoming an astrophysicist; making a decision. What do we have to loose to be aware of how good the basis for our decisions are?

Antennae Assembly

Antennae Assembly


The Antennae galaxies are among my favorite astronomical objects. I have even given this blog the nick name 'Science Antenna' with a lovely portray of the - Antennae. I was of course delighted today, when I saw that ESO's new ALMA telescope chose to publish images of the elegant galaxies dancing as the first result - the inauguration of the most impressive and highest lying! telescope on this planet.

The object consist of two galaxies merging. As they are smashing together they create billions of new stars, mostly in groups and clusters of stars. You'll even find some super star clusters as a result of this collision.

I will celebrate these events, the lovely collision AND the inauguration of ALMA, here with a series of images that I have collected over the years, starting with the latest - Antennae by ALMA! Enjoy!

The Hubble telescope registered the sharpest image of the Antennae galaxies until now. It is expected that a complete ALMA will provide much sharper images than today, so to better match these taken by Hubble.
