My first post here. I'm not sure who else to consult. Yesterday in my "Technical Physics" class, my professor went on a rant about climate change. He denied that the Earth is warming at all, but instead cooling due to solar activity. He made a claim that we are actually headed for a cooler period and that the data showing steadily increasing temperatures over the last hundred years was "bad science". He was very irate while on his rant and I didn't know enough facts off hand to debate him, so I didn't refute his opinion. Now I'm left with a very bad feeling about his class. I feel like I don't want to be taught science by him. Can anyone share some wisdom on this subject? If anyone can share credible information to support his claims I would like to see it. Thank you.
