Gentle response here that journal paywall systems have diversity and privilege problems. Not everyone doing climate-relevant research is in an academic position and paywall systems are not scaled to the economics of different fields.
I'm currently an independent consultant with a Ph.D. in anthropology doing work in climate change social science. My projects aren't directed toward producing peer-reviewed journal articles (meaning, that's not what my clients pay for), but their projects generate data and observations that are relevant to a range of climate issues. So I'm in the position of writing these up on my own time - and then being expected to pay out of my own pocket to publish the papers that I've written for free. Even when colleagues in my field get a grant, they are often in the range of $20-30,000* - and standard journal paywall fees often demand double digit percentages of that, with limits both the work and publishing we're able to do.
At the same time, climate change response needs creativity and innovation, which includes work on people and social systems. So when physical and natural science academics have grants that pay their publication fees and put up posts that assume that everyone doing necessary climate work is like them - this harms and suppresses fields like mine.
I don't have a solution to the paywall situation, but individual authors and projects paying to publish their articles isn't the answer.
* we're worth a lot more than this and could do a lot more with more funding, but see above re: systems, and power
