Yes, you're absolutely right Markimedes, your exam will have been set Sep/Oct last year and then tweaked more recently to make sure it's suitable for an online exam.
I agree with you re climate change. Subject CP1 April 2020 Paper 2 is a good one to look at for that. There was also an ST9 question on the depletion of natural resources (ST9 April 2015, Q2).
I guess Brexit is always a possibility too, I'm not aware of any past exam questions along the lines of, "A developed country is considering leaving a large customs union ...". A few links below covering the impact of a no deal Brexit.
