Global coral reef bleaching event underway as oceans get
warmer
The world’s oceans experience unprecedented rising
temperatures: last month, the average global sea surface
temperature reached a record 21° Celsius. Last week, the National
Oceanic and Atmospheric Administration (NOAA) reported the
4th global bleaching event on record. A press release stated,
“Within the last 14 months, significant coral bleaching has been
documented in the Northern and Southern Hemispheres of each
major ocean basin. Since 2023, the problem has become more
frequent in the Atlantic, Pacific and Indian oceans.”
According to NOAA, warmer ocean temperatures can result
in expulsion of algae that live in the coral tissue, leaving the coral
completely white ? something known as ‘coral bleaching’. This
does not necessarily mean corals will die, as they can recover if
the strain on their ecosystems is reduced. At a local level, storms,
disease, sediments and changes in salinity can cause corals to
bleach. However, mass bleaching, which is when several varieties
of coral reefs are bleached, is largely caused by increased sea
temperatures. When these events are sufficiently severe or
prolonged, they can cause coral mortality, which hurts the people
who depend on the coral reefs for their livelihoods.
In 2019, NOAA published a study that provided “resilience?
based management practices” and __________ the importance of
coral restoration. “We are on the frontlines of coral reef research,
management and restoration, and are actively and aggressively
implementing the recommendations of the 2019 study.” A buoy
in Florida reported an ocean temperature of 38° Celsius in July
2023, according to meteorologists at the time. In response, NOAA
started a program to attempt to offset the effects of global
climate change on the local coral reefs by moving coral nurseries
to deeper, cooler waters and deploying sunshades to protect
corals in other areas.
