Very passionate with a bit of ego, though. Pretty interesting lectures so if you pay attention to some extent it's a pretty easy and straightforward class. Tests are medium difficulty.

He's passionate about his job. Although it was at 8 in the morning, I enjoyed it because of his energy and how informative it was. Not an Earth Science major but it was a fairly easy class if you understand the material and do the homework assignments and quizzes. Great, friendly professor who cares about what he does!!! Highly recommend!

Uses iClicker, so attendance is mandatory. Really helpful, although the material wasn't really interesting to me, personally.

He is very clear with explaining information during lecture. His tests are very fair and he lets you know what to expect on them. iClicker required. Very nice professor too.

I don't think Prof Lea has an ego like some of these reviews mention, but there's certainly an air to him that's a little unconventional. He keeps the course updated as climate science advances year to year, which is pretty cool. He does attendance iclickers and very short+easy weekly quizzes. Exams curved.

He is such a kind person and a great lecturer! Always makes it easy to ask questions and explains everything so well. Readings not necessary if you take good notes in class. Weekly quizzes, midterm, final (all online) and section work weekly. Has some math in the beginning but totally manageable. Makes material accessible to non-STEM majors too!
