It actually makes sense that even though there is a decline of the antarctic ice shelves, The center of the continent is still accumulating ice and snow at a steady pace. That would be ideal for insulation and would be much easier to remove than rock and soil. The the question is how is it that on an annual basis It is accumulating 200 billion tons of snow and ice. But the outer shelves are melting, due to climate change and the planet hitting record highs some years.🤔
