[Coral-List] increasing alkalinity on a reef increases calcification

[Douglas Fenner]

Coral reefs: turning back time.
An *in situ* experiment finds that reducing the acidity of the seawater
surrounding a natural coral reef significantly increases reef
calcification, suggesting that ocean acidification may already be slowing
coral growth.

Reversal of ocean acidification enhances net coral reef calcification.

A manipulative experiment in which a reef is alkalinized *in situ* shows
that calcification rates are likely to be lower already than they were in
pre-industrial times because of acidification.

January 2016 was the hottest January since records began in 1880.  The
arctic was hottest by far.  This is the 9th straight monthly record heat.
