My experience working as a clean air and water advocate in my early 20s was that people who don't buy into climate change also tend to rationalize away things like potable water, wildlife, and preservation of natural resources. The venn diagram of people who don't "believe in" climate change and would support CO2 cuts to stop ocean acidification is tiny.
However, I'd love to be proven wrong.
This is emergent behavior from a lifetime inculcating conditioned responses to acute challenges in narrow fields of interest, combined with a lack of frame of reference to externalities. People who never plan beyond a horizon of a few decades, and only in very constrained domains, spending the vast majority of their time addressing perceived here-and-now challenges to their social/economic/personal domains are going to find it very difficult to connect with these long-term incubation period threats.
It doesn't help that Upton Sinclair, Jr.'s The Jungle is not widely-read, or reading critical analysis non-fiction is not widespread. Nor does it help that our economic system doesn't account with a high fidelity for where we establish our entropy sinks (at our current technological level, aiming as close to the outer reaches of the solar system as we can is sufficient for now, and we move the aim point higher as we acquire more energy manipulation capabilities).
Impactful stories and imagery can sometimes pierce this veil. Connecting to an imminent threat to personal, individual health seemed to galvanize the food safety and pollution control issues, which again points us back to presenting say, ocean acidification via the lens of an acute challenge to individuals.
