I had "Blue Planet 2" on in the background last night, and Attenborough mentioned that a 2C increase in ocean temperature, even just momentarily, can cause coral to die. My immediate thought was that means somewhere else temperatures have just warmed to the right temperature for coral to begin growing. Then there's the other factor, that ocean depth has to be just right for coral to grow, so that rising depth makes certain areas unsuitable for coral growth... again, that just means some other area is now made suitable for coral growth.
Pointing out changes in environment isn't a compelling argument. A compelling argument shows that something is lost and not gained back anywhere else.
As I always point out, our direct actions always cause way more disruption than indirect consequences. For instance, oceans fish populations might be affected by temperature changes, but overfishing is an even more severe problem.
