Global warming is more than a fact, it's a reality that we need to deal with. We may hear about global warming, temperatures increasing...blah blah blah, but it doesn't have much of an effect to us since we don't understand how it affects the world in general. Glaciers are shrinking, the polar ice cap is melting, and more storms are occuring due to global warming. Again, how does that affect us? I'm assuming most of us have seen "the day after tomorrow", and in theory it's pretty accurate, though it can never get that extreme that fast. The fact is that glacial ice is melting and more freshwater is being added to the ocean, which in turn decreases the salinity of the water. When the salinity decreases, the deep ocean current slows down, which makes the gulf stream slow down as well. The heat that the gulf stream contains is responsible for warming northwestern europe and greenland, but if the currents slow down, then the heat will be lost before it reaches the northern latitudes. Over the last 50 years or so the strength of the gulf stream has decreased approximately 30%, and still is decreasing. In a few decades, the temperature in western europe could drop about 18 degrees. Imagine what that would do to the fish...that's how it affects us.
