Executive editor
I agree with the handling editor that this paper shows an important aspect of heterogeneous ice nucleation in water under capillary tension. The results can be of general interest to a broad geoscience community.

Short summary
Using computer simulations of water, we find that water under tension freezes more easily than under normal conditions. A linear equation describes how freezing temperature increases with tension. Accordingly, simulations show that naturally occurring tension in water capillary bridges leads to higher freezing temperatures. This work is an early step in determining if atmospheric cloud droplets freeze due to naturally occurring tension, for example, during processes such as droplet collisions.
