Make no bones about ocean acidification

Extra carbon dioxide in the atmosphere is posing a real problem for the world's oceans. It's leading to ocean acidification and coral reefs are the big losers. See how acidification of the water leads to less calcium carbonate, a vital ingredient corals use to build their skeleton. Watch this clip to find out more.

Oil from super-greenhouse events

Why did most of the world's oil deposits form at a specific prehistoric time? Learn how overheated super-greenhouse climates caused vast stretches of the world's oceans to stagnate and become depleted of oxygen. Discover the connection between these anoxic events and Earth's oil reserves. Watch scientists investigating ...
