Uh, these articles drive me nuts from a scientific perspective.
Some of the devastated coral can never be replaced because it only grows the width of one dime a year, Miller said.
So, how did they get there?
They grew over hundreds or thousands of years. We are SO focused on human life spans. Will it regrow in a human lifespan? Probably not. Will it regrow eventually. Yeah, I think so. Will it be in the same place? Maybe not. If the oceans are getting warmer, maybe we will get reefs in different areas of the ocean where we don't have them now.
Wow, 20 years of satelite monitoring of sea surface temperature.
That is almost laughable to consider as a major source of data.
Ya know, I bet those continents moving around killed some coral, as did meteor impacts and climate changes of geologic history that had NOTHING to do with humans.
Keep in mind that scientists need money. They have to live too, and saying "Hey this is normal!" will not get you the dollars. That is not worth researching. It is not exciting. It does not make the news. Doom and destruction makes the news. I can tell you because I have been there.
We know that over geologic history these reefs are not always dominated by large massive corals. That at periods, a hypothesis called "alternate stable states," different corals and algae...yes algae...dominate reefs. This can be correlated to coral die offs or the loss of certain keystone species (eg the grazer urchin Diadema about 20 years ago).
Everything is very gloom and doom but I assure you that corals will continue on. It is adaptation or die. Maybe not as we are used to NOW, but do not confuse changes on a HUMAN lifespan with being a major variation from what occurs over GEOLOGIC time. That HUMANS think that what they see now is what is "right" and how it has always been.
Now I believe global warming exists, but I believe it has been a long long long term pattern since this planet came to be. These sort of stories just irk me.
And a guarantee you if sea surface temperatures DROPPED considerably, the article would be very very similar. In fact I think I recall reading something like that somewhere recently...must look that up.
Now don't go out and dump a barrel of oil down the storm drain, but always consider that there are parts of these stories that people don't talk about, IMO
Humans may very well be killing things off...but IMO they do not have the ability to destroy this planet. We may kill ourselves off in some way, and take stuff with us, but in the end is it much worse than some of the other things that have influenced life on the planet?
And above all, if this concerns you, I hope you are buying captive raised animals, corals and aquacultured LR....this hobby IS part of the problem in many ways.
