Explore Different Search Engines

I chose the term "global warming" to search all seven of the search engines listed. Below are the results:

Wink is a people search so of course it didn't work.
Gravee gave me 0 (zero) results, in fact it just gave me a blank page.
Exalead brought up a lot. The first three were focused on what an individual can do to help solve global warming, the next was an EPA site, there was a kids site and Wikipedia was 13 down, followed by a chevron site and then National Geographic.
Clusty brought up Wikipedia first, followed by a lot of informational sites. The Union of Concerned Scientists' site was number 8 and the scariest (I didn't even dare look at it) was a Global Warming Images site that provide relevant photos depicting the impact of climate change.
Mooter and KartOO interesting because they clustered groups of sites so that you can narrow down your search. In Kart00 I found a map of the world that was filled with little flags that when you click on them a window comes up telling of a particular early warning sign that was happening in that part of the world.
Yahoo I haven't used Yahoo in a long time and was impressed with it's "Search Assist" feature which offers relevant keywords in real time as you type your search term. I found a lot of good information.

This was a very interesting lesson. I tend to stick with Google search. I see now that I need to branch out and use different search engines.
