       In just 40 years, the Atlantic Ocean around Bermuda has become a
       lmost unrecognizable.

       On climate change and the global ocean - a recently published
       example of how things are changing at an alarming rate near
       Bermuda:

       The percentages they list may seem small, but when considering
       the time scale these are huge changes!  This still shocks me a
       bit even though I have been reading much of the published works
       of scientists who study climate change and the oceans for more
       than 20 years now.  A shelled creature, like a mussel or clam,
       cannot build a proper shell in an ocean that is too
       acidic/warm/saline (this drastically alters ocean
       biogeochemistry for shell building), and this defect changes
       their ability to reliably reproduce.  "Shelled creatures" also
       includes all of the most important species of phytoplankton, and
       phytoplankton produce about half of the oxygen in our
       atmosphere.
       It will be a completely different planet when we lose the bulk
       of the phytoplankton biomass in our oceans (whilst also watching
       wildfires ravage most our oxygen producing and carbon
       sequestering forests on land), and I believe that is coming, I
       just don't know when.  And, of equal importance, phytoplankton
       are the base for the food web in the ocean, much like grass is
       on land.  The potential for widespread damage to food webs from
       large losses in phytoplankton populations is also inevitable.
       Simply put, shit rolls downhill - more of our important
       fisheries will collapse, and it is unclear if those fisheries
       will be able to recover even if we stop fishing them for
       decades.
       This is the bottom line:
       "Similar observation stations can also be found near Hawaii, the
       Canary Islands, Iceland, and New Zealand. The researchers
       explain that all of them are seeing similarly worrying changes
       in regard to warming, salinification, and ocean acidification.
       “These observations give a sense of the rate of change in the
       recent past of ocean warming and ocean chemistry. They provide
       key indications of future changes in the next decades. They also
       are proof of regional and global environmental change and the
       existential challenges we face as individuals and societies in
       the near future... "
