Warming and acidification are only 2 of the issues.
The oceans are also still used as garbage dumps.

When it comes to the northern sections of the Great Barrier Reef heavy metals and especially copper have to be considered as a contributing factor as well. The sludge runoff from the Bougainville Copper mines on the south side of Papua New Guinea was massive and hit the GBR straight on. The mines are closed for a good while now, but the pollution is still there.

When it comes to global effects you may get a more conclusive picture when looking at the line islands: http://ocean.si.edu/ocean-news/expedition-line-islands

As for the Bikini Atoll - the nuclear fallout didn't harm the surrounding ocean much because it was washed away rather quickly and diluted in the vast volume of the Pacific and by now all other oceans as well.
