The video lectures are great but the level of guidance is nil! The Quizzes are a waste of one's precious time as one needs to rely mostly on the forum. The lecturer is nowhere to be seen on the forums nor course assistant. Looking at posts on the forums, I see students with degrees and Master degrees finding difficult to fathom answers to quizzes.

I was really excited about taking this course and I am now very disappointed. I paid for this course!

It's a very comprehensive and extremely tough course to negotiate. Some of the quiz answers are still a mystery. It has arisen the appetite of Climate Change within me, like never before.

Excellent course. My understanding of the world and how we are affected by climate has grown tenfold if not more. I recommend this to anyone who has an interest in living on this planet.

I worked really hard on this course, but was stymied by a couple of quizzes. If I could not answer one question correctly, it meant I could not answer two or three of the next questions, meaning that I could not pass quiz. With no recourse, I was prevented from passing although my overall percentage of points earned was passing. I would still like to pass, as I feel that I really earned the certificate. I would really like a chance to speak to someone who can help me resolve my questions. My other problem was using one of the models, which I never could master, despite reading the help sites and trying two or more times.

There is a lot of good information in this course, as well as access to a number of climate models. HOWEVER, the material in the quizzes is NOT the same as the material in the video lectures. Questions are NOT explained well- which, when you're dealing with math and physics, is about the worst thing I can think of. On top of not being explained well, there is next to no help to be found in the forums, and no staff around much to answer new questions from what I could see.

There is no support outside of discussion forum/others taking the class. Simulation modules are difficult and glitchy. Again without proper support or direction, these are far too difficult to understand to complete assignments. The lectures are interesting and informative however, the quizzes were often not covered in the discussions.

Databases very difficult to work with, and badly programmed.

The course tutor's explanations were very poor with lots of the physics justified with incomplete or partial explanations (ie lots of arm waving etc). The diagrams and graphs were hand-drawn and were of very poor explanatory quality - no indication of what the axes referred to, for example. As a result I found myself having to look up subjects referred to in lectures in the web. I found that web material was far superior and of greater depth (try NOAA for one). If you have reasonable knowledge of maths and physics (even high school level) this course is a waste of time. Half way through I dropped this course out of frustration and found a far superior MOOC from Univ of Bergen.

Excellent course, thoroughly enjoyable. PROS: - Lectures by Professor Archer are well explained, easy to follow and include useful diagrams. - Good breadth of topics, from basic chemistry (e.g. dipoles from vibrating molecules) to economics (e.g. viability of carbon taxes). - Videos are typically short and sweet and have useful in-lecture questions. - Plenty of opportunity to play around with a variety of climate models - The explainer assignments are useful to ensure understanding of basic principles. CONS - Quizzes can be vaguely worded and frustrating at times (stipulating how many significant figures are required in answers would help) - Some scientific and mathematical background may be helpful: for example I can imagine the explanation of oxidation / reduction status of atoms may be difficult, plus one quiz question involved a basic understanding of logarithmic equations ( I only learned these things at A-level i.e. 17-18 years old). - Peer review of written work means that requests to review work dominate the discussion boards, rather than more useful discussion of course topics.

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.

Many thanks to Prof. Archer for this amazing course!

It is not easy and you will need to spend much time to fully understand all the points raised in lectures and assignments, but in the end, you will feel like the doors of your world understanding have opened a bit more.

There are many practical quizzes and many worthy climate models to be mastered within the course, which will be extremely useful in case you deal with climate analysis and forecasting on a daily basis.

One more time thanks to professor - this is one of the best courses on Coursera and this is exactly that same level at which I would like to see other courses on the platform.

Good luck and all the best to people who were engaged in preparation of this course!

Great course!!! The course is comprehensive and it progresses at a good pace (except for week 5 and 6, too fast from my point of view). Professor Archer is a very precise and clear lecturer (he uses very helpful analogies). He writes on a blackboard and does it very well which is a nice change from the usual - poorly prepared - slides. He is calm and has a soft voice but at the same time he is not soporific for one second. If you are interested in the topic, go for it! If you're not, give it a try!

This course has given me insight into the realm of climate change. The quest to learn about climate change started with reading a research paper that I could not understand, completely. So I decided to take up this course. The course has kindled a search in me to know more about climate change and that is not going to stop. There are still some answers that I am looking for, but taking up this course has immensely helped me in my journey.

A great introductory course into Global Warming as well as modelling which gives you a better insight into what is actually happening with our planet. Started another course and it all fits in.

A detailed and really knowledgable course. The course structure and the knowledge shared by Prof. David made learning simple and interesting. The assignments are also very well structured.

Eye opening course, interesting content easily explained concepts and fantastic practice materials. Highly recommend this course to start creating conscience on issues affecting us all.

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

This course is addressing a critical subject matter. The material is great. I love the math.

But these are my personal metrics: A 4-star course has a high level of student collaboration and teaching staff participation, a 5-star course has very responsive teaching staff. I love learning the material but the learning environment is disappointing.

As the course progresses to the later weeks, the inconsistency between quizzes and lectures grows. Not greatly but enough to frustrate. Some quiz questions, with multiple choice options with only one correct answer, will not accept any answer. There are a few questions which are not covered in the video lecture (or covered in later weeks). Some answers can be found in the book (but the book supposedly is not required). Some answers can be googled but the answers vary wildly between sources.

Mathematical Thinking from Stanford is the gold standard.

No Explanation at all. It looks like the professor has spent more time in framing the questions for quizzes but little time explaining in detail the underlying cause of climate change.

I completed the course only because I wrongfully paid initially and was past the refund period. Complete waste of hard earned money.

I recommend the course, for anyone who understands some math and science. The quizzes and writing exercises were challenging in different ways, and helped me to develop my skills in computing, understanding, looking at data, and practice sharing in the enterprise of science.

I would give my performance maybe a B since I did very well in some areas (I understood the science very well, and mainly aced the quizzes) but not so well in others (in the writing assignments I kept getting into trouble with the deadlines and the interface, and in grading other people's papers sometimes I wasn't very thoughtful in my judgments and statements.)

Also, I said I understood the science very well, but also I know I could have looked more thoroughly at some parts of the science. Especially about the analysis of radiation as it interacts with the atmosphere, I think I went too fast, and relied on looking at a graph to get myself through the lesson. I am sure the graph has a solid foundation, but I would like to review that part of the course or look at that information more deeply.

There is a term project at the end that took me by surprise and I procrastinated on it - bad habit.

I decided to go ahead and purchase the course since I am willing to support the course. My finances are really not good but considering the amount of time I put into the course, I should be able to afford that much.
