what is a good research paper topic? I can only use one online source, and it has to be one of those very 'official' sites like Britanica, etc. aisde from 4 other book/newspaper/magazine resources. I was thinking about something with global warming, but it can't be that broad. Oh, what should I break it down to? I don't want to spend hours upon hours researching this in the school library :/ help anyone?
Write about the effects on global warming on the Gulf Stream and other ocean currents.
Some background: Warm ocean currents are the major factor that keeps the world's temperatures stable. They're the major reason that, while Rome and northern nebraska are at the same altitude, Rome is awesome and nebraska is ick. They're also the reason that there are temperate rainforests in Alaska. Essentially, the major Atlantic water currents flow in an approximately circular path which warms Spain, coastal Africa, the Meditteranean, melts southern icebergs, and then comes back through the tropics while warming the coast of South America, Mexico, and the Eastern United States. Around New England, the stream begins to head back towards England as it cools. A bit to the northwest of England, the cold water begins to sink toward the bottom of the ocean, where it hits an area of intense geothermal activity. These underwater volcanoes rewarm the water and it rises to the surface to continue on its path around the Atlantic, gradually cooling as it goes along with slight warmth in the tropics.
how this relates to Global Warming: With global warming, the polar ice caps in the north and south both begin to melt due to carbon dioxide increases in the atmosphere, and therfor heat increases. The few degrees from the CO2 will hardly affect anything on the planet, but the influx of cold water into both the Atlantic currents and various other ocean cycles could have dire ramifications. The warm currents mainly keep the heat because there is so much water and that much is not heated or cooled easily beccause it has a relatively minor surface area. With the general ocean temperature dropping, the air temperature will be not long to follow, and plunge the world into an almost inevitable ice age.
Please forgive my naysaying and doomtalk, I just go like that sometimes...
That's all off of the top of my head, you ought to take a look at Wikipedia before you go to the online Brittanica, even if you can't cite it, it has great information on the topic. The books about currents can be a bit dry, but they're worth it if you can get enough statistics to make it a good paper.
Have fun, whatever you choose!
