Carbon dioxide is a green house gas?

Greenhouse gases have stayed balanced for the past 150 years until what?

1

What is happening as humans continue to burn fossil fuels, like gas ?

1

The ocean absorbs much of the carbon dioxide that is released from burning fossil fuels. This extra carbon dioxide is lowering the ocean’s pH, causing it to become more acidic . When ocean water becomes more acidic it interferes with the ability of marine organisms (including crabs, and snails) to build their shells and skeletons. Without a shell or skeleton, these organisms are either left unprotected to predators or never make it to birth.

What would happen to the marine organism population if the burning of fossil fuels by humans continues to increase?
