In order to reduce the melting of polar ice, why couldn’t we use liquid nitrogen in some ways, to freeze parts of the pole’s seas?

Question

In order to reduce the melting of polar ice, why couldn’t we use liquid nitrogen in some ways, to freeze parts of the pole’s seas?

In: Physics

Answer 1

Global warming and the resulting climate change are baby versions of what all suffuciently advanced civilizations are likely to consider their most difficult problem: heat dissipation. How do you power all your cool things without cooking yourself?
