US faces a water crisis, the Colorado is at like 30% capacity, etc. At the same time, more and more ice is melting. If it all melted global sea level would rise 95-200 feet, but it won't all melt at once. I was thinking, what if we just start daming up rivers in US, and stop releasing freshwater into the Oceans. Gradually. I know ocean ecosystems depend on that freshwater, but the ice is also freshwater isn't it? It seems like doing one should be able to offset the other, if it is done at the correct pace.
Earth has been hotter in the distant, and it has had much higher levels of carbon before. It is also believed that pole shift has occurred every so often. There is even reason to believe Antarctica wasn't frozen in the medieval ages, there are maps to that effect. All the Ice probably does melt at some point, which cools the oceans down, and creates a lot of cloudy weather globally, leading to lower temperatures as Earth self corrects itself.
