While the matter is serious, you should still keep in mind that its not something like lightning happening from clear sky. Nothing is going to happen over night and even the very worst would come true, you would still have years of time to prepare and if necessary move elsewhere (if its flooding youre afraid of).
Anyhow, like it was mentioned already, its nothing you can directly affect to come true or not, so its nothing you really should stress about. Personally i would simply move elsewhere for sake of good nights sleep, if that would prevent me from sleeping.
Climate change is really something that on long term even the scientist find difficult to agree upon, so you shouldnt feel too bad about :)
And oh boy i do hate autocad. with passion.
