A new study suggests the modern (1994-2004) surface
temperatures in the South China Sea are colder now than any time in the
last 6000 years.
Except for a brief interval ~500 years ago, SSTs have been
consistently 2-4°C warmer than today since the middle Holocene in the
South China Sea (Zhou et al., 2021).
This is consistent with many other studies in the western Pacific
which also show a “decreasing SST trend” since the end of the Little Ice
Age (He et al., 2019).
