How climate change is pushing oxygen out of the world’s oceans
Species like tuna and sharks are especially vulnerable to these changes.

Since the 1960s, the oxygen level in the world’s oceans has dropped by about 2 percent. While that may not sound like a lot, the continuous decline in oxygen content of oceanic and coastal waters, called deoxygenation, can alter marine ecosystems and biodiversity. This is largely happening due to global warming and nutrient runoff.
