That megafauna didn't live in e.g. megacities (containing vital infrastructure and toxic chemical factories) built on coastal flood plains. They also didn't have a (fairly) monocultured web of food items that could be devastated by climate change. Or a bee infrastructure that was already struggling and could be tipped over into extinction which then leads to much bigger problems.
Sure, we're going to have a smaller change in climate but we're also a lot more precariously placed than they were (and about as incapable of dealing with it.)
Is it well understood why bee infrastructure is struggling? I was under impression causes behind bee problems are still unknown so I wouldn't connect it to climate change necessarily.
You are right that our civilization is very vulnerable because of our agriculture and food logistics being very fragile. A single really bad draught on a global scale would cause massive problems in feeding the large population we have.
I would argue that in this respect overpopulation is a bigger problem than climate change though. Instead of focusing on emissions and renewable energy there should be more focus on decreasing world population from current unsustainable level.

Oh, no, sorry, I wasn't - I was just saying that it was already quite wobbly and even a small push from something like climate change could topple it.
