11. Question: We expounded (Bava Basra 144b): "Hash-m will remove from you all illness" to refer to the cold!
12. Answer #1 (Tosfos, ibid.): He will warm the world or give you clothing, so you will not need to be careful.
This means that Global Warming can either be that Hashem will warm the world and its a positive thing or that Hashem will allow it to happen because its a positive thing.
But either way. Global Warming is a positive thing for the world.
