Other possible causes

Human activities

Human activities

With this link, we highlight all the degradations that humans are inflicting on marine life such as plastic pollution and overfishing. It's irrelevant to climate change, but it's interesting to make the connection anyway.
Fossil Fuels

Fossil Fuels

Oils slicks in the ocean are an example of a link between fossil fuels and marine biodiversity.
Melting of Sea Ice

Melting of Sea Ice

There's probably some sort of link here...
Hindered calcification process

Hindered calcification process

Calcification problems do not only affect pteropods and coccolithophores. Coral reefs are also affected, for example, so this link is acceptable.
