Global warming has caused a number of problems around the world, but it has amazingly been linked to resolving an issue that existed between two countries.
The countries in question were India and Bangladesh, and the dispute was over land. So, how did global warming manage to make a difference? Well, the land in question was New Moore, and it was an island. Both countries claimed control of it, as it pretty much sat between them. However, this all changed in 2010 as the island simply vanished beneath the waves, so if there was no land left, then there could be no dispute.
Now, if only other global disputes could be resolved in this manner.
