Acidic or Base whether minomer or not, warming doesn’t concern me nearly as much as the PH changes... the impact of that are far more threatening than temperature shifts.
Temperature shifts do have their own threats... Biggest would be if they started to shut down the deep water currents... as this would trigger rapidly a new ice age most likely.
However PH changes, do not have to swing in huge directions to have a major impact. If the PH gets thrown off too much, various crustacean offspring cannot form shells as it affects their ability to absorb and utilize calcium... this could rapidly affect the entire food chain and have far more widespread and rapid impact than a few degrees of temperature.
Also, mercury levels are another concern, which is undeniably a result of human activity... Unlike general climate which cannot be shown, no matter what you are told to be largely impacted by human activity.
Humans do have an impact, and we should not ignore that... And should do things to minimize it when it is undeniable... Sadly the focus of way too much is on things that are dubious in terms of human cause, to the detriment of things that are clearly human related.
