... Actually, the Climate Migration is already well under way ... ask the people living near the Southern Border. All you ever HEAR about is the crime rate and the gangs and the poverty, but this issue IS beginning to have an effect too ... and it's gonna get a LOT worse ... ☮

... And while you are throwing around the term " Ice Age " you SHOULD explain what that actually means, because a lot of people don't really know ... I do, and I get the point that you, as Climate Video producers are trying to get across - most people that get their info (mostly) from YouTube videos DON'T understand that it is a long-term condition, comprised of colder (glacial) and warmer (inter-glacial) periods ... Maybe explain it in a New video !

@Mrbfgray " The greatest threat to reefs is the rise in oceanic carbon dioxide levels. When carbon dioxide dissolves in seawater, the water becomes more acidic and the ocean’s pH (a measure of how acidic or basic the ocean is) drops. Even though the ocean is immense, enough carbon dioxide can have a major impact. In the past 200 years alone, ocean water has become 30 percent more acidic—faster than any known change in ocean chemistry in the last 50 million years. Calcium carbonate, the building block of a coral's skeleton, forms only if the water pH sits in a specific range. The more acidic seawater makes it more difficult for corals to build their calcium carbonate skeletons. And if acidification gets severe enough, it could even break apart the existing skeletons that already provide the structure for reefs. Scientists predict that by 2085 ocean conditions will be acidic enough for corals around the globe to begin to dissolve. For one reef in Hawaii this is already a reality. " ...
