I agree that is a different situation.
How about this in college I was required to do a paper on a issue facing the worlds oceans. I chose the bleaching of the worlds reefs. The research has been proven the oceans are warming at a rate that turns ocean reefs white. It destroys them. Turns them white like the description suggests. It only takes a half a degree or more over time to start this process. It has an effect on the whole food chain. So it affects the tuna and other fish we eat. The process can be reversed by getting the temps down. Part of this problem is caused by the destruction of the ozone layer that is being depleted. The suns rays are not filtered enough in the shallow waters that then reach the reefs. Combine with the temps rising it destroys the reef ecosystems.
