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!

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.

this class actually has a good amount of math despite what he says at the beginning of the class. If you're not paying attention all the time in class, it'll be very hard to do the assignments. He's not very clear on most things as far as the structure of the class.

He is very conceited/vein but he's cool. Also, he has the same tests throughout the years so just ask someone who took it before for help with studying for the midterm (the midterm is 50% of your total grade)

As a non-STEM major, this class was still one of the most engaging and interesting classes Ive ever taken. Lea genuinely wants you to learn the materials big concepts and he doesnt make you memorize tiny details. He gave extra credit to everyone on the midterm and the TAs are not harsh graders as long as you make an effort. Hes also hilarious!
