Right now no one knows for certain what will happen, so that not exactly right either. At the moment all we have are theories and trends. At present sea temperatures are up on what they used to be. The oceans are responsible for a large part of the global weather. There is more energy in the system, so there will be more high energy events eg hurricanes etc. (maybe not in the uk). It's all news now, since the recent record breaking hurricane season in the Atlantic, and with climate change conferences going on.
