But these things are clearly related, for example,
yesterday:
The journal Science has published a paper today that is
the most comprehensive review to date of the effects
rising ocean temperatures are having on the world’s
coral reefs. The Carbon Crisis: Coral Reefs under Rapid
Climate Change and Ocean Acidification, co-authored by
seventeen marine scientists from seven different
countries, reveals that most coral reefs will not
survive the drastic increases in global temperatures and
atmospheric CO2 unless governments act immediately to
combat current trends.
The paper, the cover story for this week’s issue of
Science, paints a bleak picture of a future without all
but the most resilient coral species if atmospheric CO2
levels continue on their current trajectory. Marine
biodiversity, tourism and fishing industries and the
food security of millions are at risk, the paper warns.
Coral reef fisheries in Asia currently provide protein
for one billion people and the total net economic value
of services provided by corals is estimated to be $30
billion.
Atmospheric CO2 levels are currently at 380 parts per
million (ppm) and the paper’s authors, members of the
Coral Reef Targeted Research & Capacity Building for
Management Program (CRTR), calculate that once levels
reach 560ppm, the calcification process could be reduced
by up to 40 percent. Recent science also suggests that
by 2100 the oceans will be so acidic that 70 percent of
the habitat for deep-water corals, once considered
relatively safe from the effects of climate change, will
be uninhabitable.
