Corals in Danger from Climate Change
Add coral to the long list of organisms threatened by climate change. According to a new study, global warming may be leaving corals very confused - so confused that they don't know when to reproduce.
Typically, corals reproduce by releasing sperm and egg cells into the water. They do this at the same time, in a process called synchronous spawning, to maximize their chances of success. Basically, the more sperm and egg cells that are in the water at the same time, the higher the rate of fertilization. With this in mind, corals have developed a keen sense of timing. Often, all of the coral in a reef will release their reproductive cells on the same day. Scientists do not know exactly how corals manage to time this so perfectly, but they believe it may involve water temperature, sunlight and moonlight. Researchers now believe that climate change may be disrupting this process, and causing corals to release their sex cells at different times. This greatly reduces their chances of reproductive success. Corals routinely face dangers from fishing, boating, tourism and other human activity. In light of this new research, we need to strengthen our efforts to protect coral reefs. They are a true treaure of this planet, and provide a habitat for a great number of amazing and unique species.

Coral is so beautiful, its such a shame that its our fault that its being harmed.
I am so suprised that you simply accept the statement that they are being harmed.
Coral have a relationship with other orgamism, that is why they are so important to the life of oceans. When oceans change temperature (as they have done in history, on a fairly regular cycle), the coral then change to have this "relationship" with other similar organism which are better for the coral to have this relationship with (called bleaching). It is a normal change which has happened repeatedly over history. We are simply seeing this change is some places at this time. It may continue as the normal cycle of global teperature change occurs.
This is a difficult science to follow since it relies on current biology and the history, which is somewhat incomplete (coral keep lousy blogs).
We just need to be careful not to jump to conclusions.
