This is super scary, more than the atmosphere. We know this was happening but this fast means accelerated extinctions and faster disruption of the world ecosystem.
It would've been so easy to fix it if we didn't live in a profit driven society.
It is. The oceans are the the Earth's heat sink. They can absorb a tremendous amount of heat without changing temperature much. They have soaked up much of the heat captured by greenhouse gasses over the decades and these temperatures may suggest that they cannot absorb much more.
