Warmer waters increase CO2 dissolution into the water.
- hcknwscommenter 7y agoThat is very incorrect. While heat helps dissolve ionic compounds like salt, it has the opposite effect for CO2.
- roter 7y agoCO2 solubility typically decreases with increasing water temperature [0]. [0] https://www.engineeringtoolbox.com/gases-solubility-water-d_1148.html https://www.engineeringtoolbox.com/gases-solubility-water-d_...
- duelingjello 7y agoCO2 solubility in H2O is inversely proportional to temperature but proportional to pressure. Even at 500 atmospheres (~5 km / ~15,000 ft depth), it's still not proportional to temperature. Whether a high-pressure environment precipitates out supercritical CO2 as a "solidish" hydrate or affects solubility is beyond my current laziness to look for. I would guess supercritical CO2 has a density higher than the densest water, but that's only a guess.

Sorry, that's not the intention.
