A few things I read this week on different websites and that sound close to the IMAGINE initiative:

The Planum newsletter tells us that on May 15-18, the next annual congress of the SCUPAD (Salzburg Congress on Urban Planning and Development) will focus on "Planning for the Carbon Neutral World: Challenges for Cities and Regions".

"The major challenge facing this and the next generation of architects, planners and builders is how to develop land use patterns that respond to the demands of the post-carbon age and provide a high quality of life for future generations. How our profession adapts to the need for reducing dependency on fossil fuels and contributes to the use of new technologies and approaches to planning and development that foster sustainability is critically important and will be the focus of this year’s SCUPAD Congress.[...]"

In its last newsletter, Climate Alliance echos a very interesting abstract from the Department of Evolutionary Ecology, Max Planck Institute for Evolutionary Biology. It's about... "Anxiety as method against climate change?"
"Will a group of people reach a collective target through individual contributions when everyone suffers individually if the target is missed? This "collective-risk social dilemma" exists in various social scenarios, the globally most challenging one being the prevention of dangerous climate change. Reaching the collective target requires individual sacrifice, with benefits to all but no guarantee that others will also contribute. It even seems tempting to contribute less and save money to induce others to contribute more, hence the dilemma and the risk of failure.[...]"
