Oceans warming much faster than previously thought

Oceans heating up faster than expected, set record in 2018

Climate scientists alarmed at speed of ocean warming

In fact, the Earth's oceans are warming 40% faster than that United Nations panel predicted, according to new analysis published Thursday in the journal Science.

The planet is "clearly warming", according to the analysis.

A resident of Pariahan village pumps drinking water from a well, on November 28, 2018 in Bulacan, north of Manila in the Philippines.

The thermal expansion - water swelling as it warms - would raise sea level 30 centimeters, above any sea level rise from melting glaciers and ice sheets. This Trend has far-reaching consequences for fish or other organisms in the already oxygen-poor marine regions, for example, because in particular large fish in oxygen are not able to survive poor areas.

Human-made greenhouse gas emissions are still heating up the Earth's atmosphere, and the majority of that heat goes into the oceans, as the scientists revealed in recent studies. On January 11, 2019, an important article in Science magazine asks the question about "How fast are the oceans warming?"

Huawei fires sales director arrested in Poland, says case not related
A LinkedIn profile for a man named Stanislaw Wang appears to match details of the man described by Polish television. Yesterday, we reported that two Huawei employees have been arrested in Poland over allegations of espionage .

Mr Hausfather said: "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". "2018 was the warmest year on record for the global ocean, surpassing 2017", added the research leading author, Lijing Cheng at the Institute of Atmospheric Physics at the Chinese Academy of Sciences. The studies accounted for the fact that older assessments of ocean temperature relied on less accurate methods than we have today.

Overall, temperatures in the ocean down to 2,000 metres rose about 0.1 degree Celsius (0.18F) from 1971-2010, he said.

In the Arctic, the warming oceans are also causing a serious decline in sea ice, which only compounds the ongoing threats of climate change such as sea level rise. Dubbed Argo, the AI fleet has provided consistent ocean warming data since the mid-2000s, and enabled the team to correct previous ocean warming observations. U.S. President Donald Trump, who wants to promote U.S. fossil fuels, plans to pull out of the pact in 2020.

"If the ocean wasn't absorbing as much heat, the surface of the land would heat up much faster than it is right now", Malin Pinsky, an associate professor in the department of ecology, evolution and natural resources at Rutgers University, told The New York Times. For over a decade, more than 3000 floats have provided near-global data coverage for the upper 2000 m of the ocean.

A warmer ocean also contributes to increases in rainfall and leads to stronger and longer-lasting storms like Hurricanes Florence and Harvey.
