The next story on that topic says that we've only been monitoring Coral for a very limited amount of time. The glaciers that are receding are revealing signs of past human habitation in those areas, which would seem to indicate that when the local climate changes humans move away

That's assuming CO2 wiped out the coral. That's my point. Someone says global warming is the reason and you can find someone who says the opposite. Alternative Energy can't meet the energy requirements so fossil fuels aren't going anywhere anytime soon. Find a use for CO2 instead

I would consider microplastics and water contamination to be much bigger problems. I want to eat a piece of fish that's full of plastic like most of it is today. I don't want to be at the perfect temperature and not have a clean glass of water to drink.

Warming is the biggest coral killer by far now. I've done extensive homework here. "Someone says it isn't global warming" – who? Coral experts 100% in agreement on that afaik. This paper includes authors from all major scientific reef orgs including NOAA http://www.nature.com/articles/nature21707.epdf …pic.twitter.com/xCakOKXSVr

I find coral extinction difficult to grasp. Coral first evolved ~500 mil years ago, and survived the PETM ~50 mil years ago. With the claimed lethal sensitivity to 1°C, how the hell did they make to present day? The species that survived necessarily would be more heat resistant.

Most coral disappeared during the PETM. Coral may well survive now, but the existing reefs won't, and impact to humans, ecosystems, food sources and economies scale with cover, not survival. They survived by moving and adapting, of course, but pace is key...

Well the current coral species managed to survive similar temps in the past 10k years for several thousand years. That should have wiped them out according to current projections.pic.twitter.com/afEWGowY4l

Pace of change is the key factor (per papers). Thermal tolerance varies by areas they've adapted to. If temp changes slowly, reefs simply migrate or adapt. That screaming rise on the right end is the challenge; there aren't easy historical comparisons. http://scientiamarina.revistas.csic.es/index.php/scientiamarina/article/viewArticle/1352 …

Also, there are marine biologists finding some species which are adapting better than others. There is active work on creating "heat-resistant" strains but as Geoff said, all bets are off if the rate of temp rise is too great.https://video.nationalgeographic.com/video/news/00000153-a3a3-d742-a553-b7efc7fe0000 …

That only applies to specific areas. Does coral have to stay where it is?
