im not sure I would call the last point anxiety. As existential threats go its not like nuclear war. Which might or might not happen based on our actions. Its something that is definately happening and extreme good action by us might mitigate it but we by and large have been taking worse actions or at best our beneficial vs non beneficial actions cancel each other out. Heck even without climate change pollution alone has the same ending.

“apprehensive uneasiness or nervousness usually over an impending or anticipated ill : a state of being anxious” -Merriam Webster
Nothing about the word ‘anxiety’ implies that it’s an unrealistic or irrational feeling. You might be thinking of phobias.
