Communists hate food. But no one hated food more than stalins favorite gardener Trofim Lysenko.
You could try planting plants in colder and colder environments and see which ones survive the ones that survive could be reprduced this would take multiple generations but could produce cold growing food plants to a certain degree
That would be a question for engineers construction workers and architects
That would also not help the plants that are more cold resistant reproduce their cold resistant genes through artifical selection
