Well, the last thing about oceanic circulation seemed pretty important. I know I go into a lot of detail but it's important that understand the little details in order to come with a simpler system. Sometimes a lot of these details are irrelevant but unless you have an idea of the whole picture, who can't realize they are.

No we don't understand all the climate on Earth. I don't delve into thermohaline circulation or El Nino because their impact of the climate and why they form is not fully understood. Maybe the thermohaline makes the Brazil current weaker than the Gulf stream but it does not seems to have any meaningful impact ...

I just need to go into a lot of details to eventually be able to explain it simply with a model.
