The world’s oceans are heating up at an accelerating pace as global warming threatens a diverse range of marine life and a major food supply for the planet, researchers said Thursday.
The findings in the US journal Science, led by the Chinese Academy of Sciences, debunk previous reports that suggested a so-called pause in global warming in recent years.
The latest technology shows no such hiatus ever existed, raising new concerns about the pace of climate change and its effect on the planet’s main buffer — the oceans.
“Ocean heating is a very important indicator of climate change, and we have robust evidence that it is warming more rapidly than we thought,” said co-author Zeke Hausfather, a graduate student in the Energy and Resources Group at the University of California, Berkeley.
About 93 percent of excess heat — trapped around the Earth by greenhouse gases that come from the burning of fossil fuels — accumulates in the world’s oceans.
The latest report relied on four studies, published between 2014 and 2017, that gave more precise estimates of past trends in ocean heat, allowing scientists to update past research and hone predictions for the future.
A key factor in the more accurate numbers is an ocean monitoring fleet called Argo, which includes nearly 4,000 floating robots that “drift throughout the world’s oceans, every few days diving to a depth of 2,000 meters (yards) and measuring the ocean’s temperature, pH, salinity and other bits of information as they rise back up,” said the report.
Argo “has provided consistent and widespread data on ocean heat content since the mid-2000s,” it said.
The new analysis shows warming in the oceans is on pace with measurements of rising air temperature.
And if nothing is done to reduce greenhouse gases, “models predict that the temperature of the top 2,000 meters of the world’s oceans will rise 0.78 degrees Celsius by the end of the century,” it said.
The thermal expansion — water swelling as it warms — would raise sea level 12 inches (30 centimeters), above any sea level rise from melting glaciers and ice sheets.
“While 2018 will be the fourth warmest year on record on the surface, it will most certainly be the warmest year on record in the oceans, as was 2017 and 2016 before that,” Hausfather said.
“The global warming signal is a lot easier to detect if it is changing in the oceans than on the surface.”
Cop says Alexandria Ocasio-Cortez should be shot following Trump’s racist targeting of The Squad
Following racist attacks on members of The Squad by President Donald Trump and his supporters, a police officer in Louisiana reportedly said that one of the congresswomen of color should be shot.
Trump has been lashing out at the four first-term congresswomen, who include Representatives Alexandria Ocasio-Cortez (D-NY), Ilhan Omar (D-MN), Ayanna Pressley (D-MA), and Rashida Tlaib (D-MI).
"A Gretna police officer posted a comment on his Facebook page this past week calling U.S. Rep. Alexandria Ocasio-Cortez a 'vile idiot' who 'needs a round, and I don't mean the kind she used to serve,'" NOLA reported Saturday.
Internet piles on ABC reporter for lavishing praise on Trump for allowing press to ask questions
ABC News reporter Kyra Phillips on Saturday heaped praise on President Donald Trump for his treatment of the press.
Despite the White House no longer holding daily press briefings, Phillips praised the "access" she receives from the administration.
"No matter what your politics are, I have to say that I appreciate the access ?Trump? gives us on a regular basis and the ability to ask any question," she said.
She tagged Stephanie Grisham in her tweet, who is Trump's latest press secretary. She also tagged her husband, John Roberts, who does not work in the White House, but works for Fox News.
‘Trump wants to start a race war’: Ex-advisor alleges his campaign planned ‘Send her Back’ chants
President Donald Trump is attempting to start a race war in America, a long-time advisor declared on MSNBC on Saturday evening.
Omarosa Manigault Newman was interviewed by Donny Deutsch on "Saturday Night Politics."
"You said could it happen here? It is happening here," Newman told Deutsch.
"As a woman of color watching him attack those four women, it made it very clear that Donald Trump is a clear and present danger to our democracy," she said.
"And everyone has been kind of tiptoeing what this actually is. Donald Trump wants to start a race war in this country and it started at that rally — it started with the tweets," she said.
