Earthquake levels city of Antakya in southern Turkey
The Turkish city of Antakya, one of the hardest‐hit towns in
the earthquake zone, has been nearly destroyed by the massive
7.8 quake that struck on 6th February. Tall apartment buildings
were flattened, trapping residents who were sleeping when the
quake struck in the early morning hours. Thousands are
__________ to be buried in their homes. Most of the city was
heavily damaged and rescuers have been working around the
clock to pull survivors from under the rubble, racing against time
in cold weather. Many residents were left homeless and had to
spend nights outdoors, burning debris to keep warm as overnight
temperatures dropped below freezing. Workers pulled a man in
his 30s out of the ruins as a jubilant crowd burst into cheers and
tears. Not long after, they found an elderly woman. Then, a 10‐
year‐old girl was also rescued: the child was under the rubble for
90 hours. These moments of hope among the devastation keep
them going as darkness falls. More than 80 hours after the quake,
rescuers using pails along with other equipment, found a man and
his mother, and pulled them out alive. Amid the rubble, a group
of rescuers were able to pull out lost family members alive.
Even as more help arrives, hope for finding survivors
dwindles. Family members wait in the cold to see if their loved
ones will be found, alive or dead. There are more than 100 bodies
waiting for identification in a makeshift morgue outside the
Antakya hospital. More than 600 aftershocks are slowing recovery
efforts and make the task more dangerous. Little aid from the
government has reached the city and the need is overwhelming.
People walk the streets in tears, dazed. There is no place to go.
Everything is covered in dust. Even with some 120,000 rescuers
across Turkey and Syria now taking part in the effort, the task is
daunting. With every passing hour, the likelihood of finding
survivors diminishes.

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.
