This! The idea that nature is balanced is strange since nature changes locally all the time. The issue with global warming is that it is a global change that chances every local ecosystem in such a fast way that the evolutionary processes are not adapting. In many ways, each animal's birth rate is calibrated for its the local environment and how fast it changes. Since if the animal had too many babies too quickly it could die off or if it had too many babies too slowly it can die off. So animals that have survived their habitats for a long time have a calibrated birth rate.
Global warming is changing the rate of how fast local habitats change and therefore NO ANIMAL ON THIS PLANET is likely going to be able to handle the rate of change. Which is why we are in the 6th mass extinction.
In other words, animal life is locally calibrated, not globally and if you change the global system (therefore changing every local system quickly) you will get a bad bad situation.
My guess is that cockroach will be fine. Perhaps no all species of cockroach.
Some animals have a wide distribution. Sparrows live in a wide range of climate, they have different size (in cold climates, they are bigger). Many birds migrate, some of them can probably change the extremes of the migration path and be fine.
I'm more worried for elephants and other animals with a long lifespan and small area where they can survive. (And I'm more worried about trees, because they can't move.)
