How do oceans warm?

The ocean absorbs a lot of the trapped heat on earth and this is primarily caused by greenhouse gas emissions. The more greenhouse gases trapped in our atmosphere, the more ocean warming will occur

It is important to know that oceans absorbs 31% of C02 emissions that are released into the atmosphere. The lungs of the planet is also its largest carbon sink according to the United Nations.

How coral reefs are affected: You may have heard of coral bleaching, and that is when corals can lose their color and become vulnerable. They expel the algae in their tissues in which case, they turn white. Essentially they become stressed out; this is a response to warming ocean temperatures, and acidification.

Ocean warming does not cause acidification, and ocean acidification doesn’t cause ocean warming. Acidification is caused by C02 being absorbed into the ocean from the atmosphere. This lowers the ph levels increasing the ocean’s acidity. In conclusion, the warming of ocean is caused by greenhouse gas emissions in atmosphere making it so that heat radiated on to earth’s surface can’t escape as freely as it used to, resulting in the excess heat warming ocean temperatures.
