How can you determine if a resource is biased?

There are a couple of things to consider: first, where did you find the information? Academic databases tend to be more reliable than information found from a google search. There are always things to consider though. Check the author(s) affiliations: do they work for a company that may want to present the information in a certain light? Check the publisher: is the information coming from a known Conservative think tank? A religious group? Do other resources support the same conclusions? It is important when doing research to not take a single piece of information as definite. Always be willing to dig a little more.

How do ocean currents affect our climate?

Ocean currents move large amounts of water from one geographical area to another. This can result in the movement of nutrients, but also the movement of masses of water of different temperatures. An example of an ocean current that affects climate is the Gulf Stream. This current brings warmer water from region of the Caribbean up the Atlantic and across to the United Kingdom, where it keeps the climate a bit warmer than that of the United States along the same latitude.
