Global warming pushes ocean temperatures off the charts: study

  • Oceans soaked up around 9 to 15 zettajoules more than in 2022, according to estimates from the US NOAA and the Chinese Institute of Atmospheric Physics
  • Some of the colossal amounts of energy stored in the ocean helped make 2023, a year rife with heatwaves, droughts and wildfires, the hottest on record

PARIS: In 2023, the world’s oceans took up an enormous amount of excess heat, enough to “boil away billions of Olympic-sized swimming pools,” according to an annual report published Thursday.
Oceans cover 70 percent of the planet and have kept the Earth’s surface livable by absorbing 90 percent of the excess heat produced by the carbon pollution from human activity since the dawn of the industrial age.
In 2023, the oceans soaked up around 9 to 15 zettajoules more than in 2022, according to the respective estimates from the US National Oceanic and Atmospheric Administration (NOAA) and the Chinese Institute of Atmospheric Physics (IAP).
One zettajoule of energy is roughly equivalent to ten times the electricity generated worldwide in a year.
“Annually the entire globe consumes around half a zettajoule of energy to fuel our economies,” according to statement.
“Another way to think about this is 15 zettajoules is enough energy to boil away 2.3 billion Olympic-sized swimming pools.”

In 2023, sea surface temperature and the energy stored in the upper 2000 meters of the ocean both reached record highs, according to the study published in the journal Advances in Atmospheric Sciences.
The amount of energy stored in the oceans is a key indicator of global warming because it is less affected by natural climate variability than sea surface temperature.
Some of the colossal amounts of energy stored in the ocean helped make 2023, a year rife with heatwaves, droughts and wildfires, the hottest on record.
That’s because the warmer the oceans gets, the more heat and moisture enters the atmosphere. This leads to increasingly erratic weather, like fierce winds and powerful rain.
Warmer sea surface temperatures are driven mostly by global warming, caused mainly by the burning of fossil fuels.
Every few years, a naturally occurring weather phenomenon, El Nino, warms the sea surface in the southern Pacific, leading to hotter weather globally. The current El Nino is expected to peak in 2024.
Conversely, a mirror phenomenon called La Nina periodically helps cool the surface of the ocean.
Increasing water temperatures and ocean salinity — also at an all-time high — directly contribute to a process of “stratification,” where water separates into layers that no longer mix.
This has wide-ranging implications because it affects the exchange of heat, oxygen and carbon between the ocean and atmosphere, with effects including a loss of oxygen in the ocean.
Scientists are also concerned about the long-term capacity of the oceans to continue absorbing 90 percent of the excess heat from human activity.

Court records raise doubts that ICE is detaining the ‘worst of the worst’ in Maine

  • Federal officials say more than 100 people have been detained statewide enforcement ‘Operation Catch of the Day’
  • ICE has said the operation is targeting about 1,400 immigrants in a state of about 1.4 million people
PORTLAND, Maine: Immigration and Customs Enforcement has highlighted the detention of people whom it called some of Maine’s most dangerous criminals during operations this past week, but court records paint a more complicated picture.
Federal officials say more than 100 people have been detained statewide in what ICE dubbed “Operation Catch of the Day,” a reference to the fishing industry. ICE said in a statement that it was arresting the “worst of the worst,” including “child abusers and hostage takers.”
Court records show some were violent felons. But they also show other detainees with unresolved immigration proceedings or who were arrested but never convicted of a crime.
Immigration attorneys and local officials say similar concerns have surfaced in other cities where ICE has conducted enforcement surges and many of those targeted lacked criminal records.
One case highlighted by ICE that involves serious felony offenses and criminal convictions is that of Sudan native Dominic Ali. ICE said Ali was convicted of false imprisonment, aggravated assault, assault, obstructing justice and violating a protective order.
Court records show Ali was convicted in 2004 of violating a protective order and in 2008 of second-degree assault, false imprisonment and obstructing the reporting of a crime. In the latter case, prosecutors said he threw his girlfriend to the floor of her New Hampshire apartment, kicked her and broke her collarbone.
“His conduct amounted to nothing less than torture,” Judge James Barry said in 2009 before sentencing Ali to five to 10 years in prison.
Ali was later paroled to ICE custody, and in 2013 an immigration judge ordered his removal. No further information was available from the Executive Office for Immigration Review, and it remains unclear what happened after that order.
Other cases were more nuanced, like that of Elmara Correia, an Angola native whom ICE highlighted in its public promotion of the operation, saying she was “arrested previously for endangering the welfare of a child.”
Maine court records show someone with that name was charged in 2023 with violating a law related to learner’s permits for new drivers, a case that was later dismissed.
Correia filed a petition Wednesday challenging her detention, and a judge issued a temporary emergency order barring authorities from transferring her from Massachusetts, where she is being held. Her attorney said she entered the United States legally on a student visa about eight years ago and has never been subject to expedited removal proceedings.
“Was she found not guilty, or are we just going to be satisfied that she was arrested?” Portland Mayor Mark Dion said during a news conference in which he raised concerns that ICE failed to distinguish between arrests and convictions or explain whether sentences were served.
Dion also pointed to another person named in the release: Dany Lopez-Cortez, whom ICE said is a “criminal illegal alien” from Guatemala who was convicted of operating under the influence.
ICE highlighted Lopez-Cortez’s case among a small group of examples it said reflected the types of arrests made during the operation. Dion questioned whether an operating-under-the-influence conviction, a serious offense but one commonly seen in Maine, should rise to the level of ICE’s “worst of the worst” public narrative.
Boston immigration attorney Caitlyn Burgess said her office filed habeas petitions Thursday on behalf of four clients who were detained in Maine and transferred to Massachusetts.
The most serious charge any of them faced was driving without a license, Burgess said, and all had pending immigration court cases or applications.
“Habeas petitions are often the only tool available to stop rapid transfers that sever access to counsel and disrupt pending immigration proceedings,” she said.
Attorney Samantha McHugh said she filed five habeas petitions on behalf of Maine detainees Thursday and expected to file three more soon.
“None of these individuals have any criminal record,” said McHugh, who is representing a total of eight detainees. “They were simply at work, eating lunch, when unmarked vehicles arrived and immigration agents trespassed on private property to detain them.”
Federal court records show that immigration cases involving criminal convictions can remain unresolved or be revisited years later.
Another whose mug shot was included in materials on “the worst of the worst” of those detained in Maine is Ambessa Berhe.
Berhe was convicted of cocaine possession and assaulting a police officer in 1996 and cocaine possession in 2003.
In 2006 a federal appeals court in Boston vacated a removal order for him and sent the case back to the Board of Immigration Appeals for further consideration.
According to the ruling, Berhe was born in Ethiopia and later taken to Sudan by his adoptive parents. The family was admitted to the United States as refugees in 1987, when he was about 9.
ICE has said the operation is targeting about 1,400 immigrants in a state of about 1.4 million people, roughly four percent of whom are foreign-born.
