Hot oceans could mean hotter air
Warm oceans could induce microbes to release more CO2 in air - interesting science news

The oceans absorb more than 25% of the CO2 release by humans and are considered as a powerful break on the greenhouse effect. However, this might change due to rising ocean temperatures due to global warming.

Most of the locked CO2 by the oceans is courtesy to the photosynthetic planktons and when they die, they go to the bottom of the ocean taking the CO2 with them. However, as the temperatures rise, bacteria are consuming more planktons at the surface and thereby release the CO2 back to the air.

This could accelerate the effects of climate change as the proverbial ‘powerful brakes’ fail over time due to raising ocean temperatures.
