Are geologists different?

Filed under: — rasmus @ 19 August 2008

rockThe International Geological Congress (IGC) is sometimes referred to as the geologists’ equivalent of the Olympic Games and is an extremely large gathering of geologists from all over the world, taking place at 4-year intervals. This time, the IGC took place in Lillestrøm, a small place just outside Oslo, Norway (August 6-14). The congress was opened by the Norwegian King (before he continued to the real games in Beijing), and was attended by some 6,000 scientists from 113 countries. Even the Danish Minister of Energy & Climate participated in a panel discussion on climate change. In other words, this was a serious meeting.

A day when Hell was frozen

Filed under: — rasmus @ 7 February 2008

“Hell train station” I was honoured to be invited to the annual regional conference for Norwegian journalists, taking place annually in a small town called ‘Hell’ (Try Earth Google ‘Hell, Norway’). During this conference, I was asked to participate in a panel debate about the theme: ‘Climate – how should we [the media] deal with world’s most pressing issue?’ (my translation from Norwegian; by the way ‘Gods expedition’ means ‘Cargo shipment’ in ‘old’ Norwegian dialect).

Spanish perspectives

Filed under: — rasmus @ 9 October 2007

San Lorenzo de El EscorialThe main theme of the European Meteorological Society (EMS) annual meeting was high impact weather. This includes extreme weather and the predictability of these.

The majority of the presentations focused on the science, but aspects such as the utility and the benefit of meteorology and climatology were also discussed. A media session also provided some thoughts about outreach and presented some examples of how weather is presented on TV. While gender and educational issues were discussed, the underrepresentation of other minorities was neglected.

Why global climate models do not give a realistic description of the local climate

Filed under: — rasmus @ 27 May 2007 - (Português)

Global climate
glasses Global climate statistics, such as the global mean temperature, provide good indicators as to how our global climate varies (e.g. see here). However, most people are not directly affected by global climate statistics. They care about the local climate; the temperature, rainfall and wind where they are. When you look at the impacts of a climate change or specific adaptations to a climate change, you often need to know how a global warming will affect the local climate.

Yet, whereas the global climate models (GCMs) tend to describe the global climate statistics reasonably well, they do not provide a representative description of the local climate. Regional climate models (RCMs) do a better job at representing climate on a smaller scale, but their spatial resolution is still fairly coarse compared to how the local climate may vary spatially in regions with complex terrain. This fact is not a general flaw of climate models, but just the climate models’ limitation. I will try to explain why this is below.
