Obsession with timelines

I am 19 and struggle with OCD. For the last 4.5 months my obsession has been climate change. I've been a lot better in the last few months but I still have days where I experience anxiety or more often feel tension in my body and have climate change at the back of my mind. A problem I have is with trying to form timelines of when collapse will happen. Like I've seen people say 2 degrees will be reached in 2030 while others say it will be mid /late 2030s. Does anyone have any advice on how I can stop fixating on these timelines and lack of certainty about the future and enjoy my life as I finally have been after a few months? I have also had pretty bad OCD over other things since mid 2023, though it's better than it's been in years now.
