There is a scientific consensus on the topic, so one could see why it may appear like a 'pushed' agenda. Scientists are not easily swayed by adverts on TV, radio, disagreeable slashdotters, etc.. They come to conclusions by looking at data (try it, there's a fuck ton on climate science), examining their methods, examining the conclusions drawn from the data sets, verifying that other experiments of a similar nature present data that agrees or disagrees.
And you know what? They keep looking for more data. They may even set up their own experiments. They are smart mother fuckers that love to know how the world works, their effect on it, and their place in it. They also enjoy finding out new things. So if they run a test and the results disagree with the current body of data, they present it all over the place, and they have their methods examined, their testing redone, and they are either shown to be right or wrong.... eventually. Hell, if they are right about something major, we give them a million bucks and a medal!
Currently, there is a 97% consensus among climate scientists that not only is the climate changing dramatically, but humans are the likely cause via the burning of fossil fuels.

When you start your research, it would be prudent to start at NOAA before BP, as sometimes conflicts of interest exist -- even in science. Something something money.
