"The twin stress factors of ocean warming and acidification increasingly
threaten coral reefs worldwide, but relatively little is known about how
various climate scenarios will affect coral reef growth rates.
Our research, published today, paints a grim picture. We estimate that even
under the most optimistic emissions scenarios, we’ll see dramatic reductions in
coral reef growth globally. The good news is that 63% of all reefs in this
emissions scenario will still be able to grow by 2100.
But if emissions continue to rise unabated, we predict 94% of coral reefs
globally will be eroding by 2050. Even under an intermediate emissions
scenario, we project a worst-case outcome in which coral reefs on average will
no longer be able to grow vertically by 2100.
The latter scenarios would have dramatic consequences for marine biodiversity
and the millions of people who depend on healthy, actively growing coral reefs
for livelihoods and shoreline protection. This highlights the urgency and
importance of acting now to drastically reduce carbon dioxide emissions."
