Key message An influence of the recent changes in temperature or rainfall was demonstrated, increasing background tree mortality rates for 2/3 of the 12 studied tree species. Climate change-induced tree mortality was exacerbated towards the warm or dry limits of the species ranges, suggesting in these areas a progressive replacement by more xeric s...

In our everyday experience, life, environment, and nature are connected and we tend to confuse the value we assign to them. One way around this issue is to analyze our intuitions on the terraformation of other planets such as Mars. In this way, we are forced to consider whether the original abiotic nature has a value of some kind regardless of its...
