”A one-degree global change is significant because it takes a vast amount of heat to warm all the oceans, atmosphere, and land by that much. In the past, a one- to two-degree drop was all it took to plunge the Earth into the Little Ice Age. A five-degree drop was enough to bury a large part of North America under a towering mass of ice 20,000 years ago."

We are causing climate change, it's not a debate anymore.

Russia is heavily investing in ice breakers (some armed) so they can control the Arctic shipping lanes and natural resources. The USA has two, and they're both about 40 years old. We need to get our heads out of the sand.
