Weather Visualization: Fast & Slow

sea surface temperatures surrounding hurricane Katrina

NASA has done a wonderful visualization of the 2005 hurricane season showing the named storms from June 1 up until Oct 17 (missing Alpha and only getting the start of Wilma).

It reveals how weather patterns (fast variables) are structured by ocean temperatures (a slower variable) along with the storm paths.

Identifying changes in slow variables is an important part of managing for resilience. For a quick introduction to this idea see Lance Gunderson’s short 1999 article Resilient management: comments on “Ecological and social dynamics in simple models of ecosystem management”.

Climate Change Games

In Playing Games with the Climate WorldChanging discusses several games sponsored by the European Climate Forum, including Keep Cool - a climate change policy board game co-developed by Gerhard Petschel Held from Potsdam Institute for Climate Impact Research (PIK).

The game Keep Cool was a hit in Germany, where it sold out of stores.

The game lets:

each player takes a role within global climate politics. You have to put through economic interests, e.g. of the USA and its partners or of the Developing Countries. Yet you must not forget the strong lobby groups in your country like the oil industry or environmental groups as they also decide whether you win or loose. Within each round of the game you have to decide between measures for climate protection good for all and egoistic decisions just for your owns sake. The risk: catastrophes like droughts, floods or pandemics. The chance: welfare and a stable global climate. Whoever reaches his or her targets first wins, yet if you are not cooperative enough all players might loose due to a collapse of the world climate.

Tragically, and unexpectedly, Gerhard died in the summer of 2005. Those of us who knew him lost of great friend, while the scientific community lost a great mind.
