The climate and ecological crisis poses an unprecedented challenge, with scientists playing a critical role in how society understands and responds. This study examined how 27 environmentally concerned scientists from 11 countries construct the future in the context of climate change, applying a critical discursive psychology analysis. The degree to which the future is constructed as predetermined or transformable impacts both the urgency and scope of proposed actions. ...
With the help of the contingency concept, the article explores the reasons behind these surprises by introducing a new category of threats that complements the ones in the existing literature on surprise. It adds the concept of ‘known—corporally unknown’ threats to the list of known-unknowns, unknown-unknowns as a way to emsphasize the difference between abstract knowledge of ‘facts and figures’ (of e.g., global warming) and the acquiring of knowledge through personal, bodily experience (tangere) (of flooding and draughts).

After 50 years, there is still an ongoing debate about the Limits to Growth (LtG) study. This paper recalibrates the 2005 World3-03 model. The input parameters are changed to better match empirical data on world development. An iterative method is used to compute and optimize different parameter sets. This improved parameter set results in a World3 simulation that shows the same overshoot and collapse mode in the coming decade as the original business as usual scenario of the LtG standard run. The main effect of the recalibration update is to raise the peaks of most variables and move them a few years into the future. The parameters with the largest relative changes are those related to industrial capital lifetime, pollution transmission delay, and urban-industrial land development time.
