16
Q

Why doesn’t sea ice contribute to rise in sea level

A

Sea ice is formed in the sea already so the mass of water in the ice is already represented by the level of water

17
Q

Melting of permafrost can cause what?

A

Release of greenhouse gases, collapse of infrastructure, mudslides

18
Q

How does the ocean help prevent warming?

A

It absorbs most of the heat energy, and directly absorbs CO2

19
Q

What reaction happens when the ocean absorbs CO2?

A

CO2 combined with H2O releases H+ which contributes to acidification

20
Q

What is an effect of ocean warming?

A

More intense storms, more melted ice
