For a longer time I have wanted to know more about the scientific background of climate change and global warming, and I am glad that I finally found the time to do this course. I liked the interactive aspect and the variety of tasks including writing small reports and explanations and reading the ones of other students as well as getting feedback from them. This interaction and combination of learning forms is way more effective than just reading a book, I think.

What I do not understand is the grading system for the final task, the term project. There is a scale ranging from 1 to 10, but you can only give a 1,4,7 or 10. It seems that, if do not get a 10 from someone, you fail the whole course. I don't think that this is fair.

Highly interesting, informative, challenging and time-consuming course, which has some frustrations when it comes to the exercises. I wish it was still maintained to iron out remaining quirks.

There appears to be no statement of accomplishment unless you buy the certificate.

Very good!

Great course content. Optional exercises seemed to have minor glitches with answers.

best one

One of the best courses on climate change.

This is a great course for the non-scientist to understand the scientific mechanism and models behind climate change. I requires quite a bit of work but the lecturer explains things extremely well. Overall, some of the quizzes could be better thought through but this is a very good MOOC.

It was an amazing class. The content was thorough and I really enjoyed all the models that I got to study. One improvement, however, would be making the peer edits more accessible. I finished this course in three months but then spent the next four waiting for other students from various "sessions" to submit their papers so that I could pass the peer-grading portion. I didn't learn the trick of actively switching between course dates until recently. But overall it was really informative :)

Good course! in hindsight i wish i bought the book at the beginning/there were some written summaries/pdfs of the key points.

Very nice balance of quizzes and interacting with the models. Very clear lectures. I also appreciated that Prof. Archer kept a sharp line between the known and the maybes.
