Personally I have found reading both history and philosophy is helpful - not in "solving the problem" but being able to manage emotion and anxiety about climate change. I think learning about previous periods of large-scale ecological change or collapse of civilisations helps to normalise the possible/likely/inevitable upcoming events intellectually. Philosophy helps to figure out a workable emotional response. I think there is some value in stoic philosophy that can be applied in daily living, particularly in terms of managing responses to loss (e.g. loss of one's health, or one's material possessions, or loved one's, or perhaps one's society)
There's also this - Roy Scranton's "Learning How to Die in the Anthropocene":

> The biggest problem climate change poses isn’t how the Department of Defense should plan for resource wars, or how we should put up sea walls to protect Alphabet City, or when we should evacuate Hoboken. It won’t be addressed by buying a Prius, signing a treaty, or turning off the air-conditioning. The biggest problem we face is a philosophical one: understanding that this civilization is already dead. The sooner we confront this problem, and the sooner we realize there’s nothing we can do to save ourselves, the sooner we can get down to the hard work of adapting, with mortal humility, to our new reality.
i am not sure if you will find any of this helpful but i hope that you can find some peace with time
