Here’s a mammoth controversy on climate. Geneticists at @Harvard are trying to create an elephant-mammoth hybrid to combat climate change. The mammoth’s trampling power can compact snow cover that acts as insulation for the ground in tundra environments, which can make permafrost melt more quickly. There are currently no large animals in this ecosystem to facilitate the task of trampling snow, and permafrost is needed to stop the release of greenhouse gases stored underground. Most climate models do not take into account permafrost melt, which could double the amount of carbon in our atmosphere. However, is bringing this beast back to life really the best solution?
