Why is the climate change issue divided along party lines?

CNN isnt my Go-to, but it can generally pass a fact check search and doesn't feature opinion and commentary over actual news.
Generally, I use AP, NPR, and NBC as morning go-to, trying Smartnews as an aggregator, which gets into the weeds on both sides. I tend to avoid sites with a known bias like Breitbart as credible news sources.
