Study Finds Ocean Warming Is Largely Man-Made

Responding to Climate Change

The study, published in Nature Climate Change, examined rising ocean temperatures over the past five decades and compared them with a dozen different models used to project climate change.

It found that while 10 percent of the rising temperatures could be blamed on natural variations, man-made greenhouse gases were the major cause.

The researchers looked at the average temperature in the upper layers of the ocean—from the surface to 700 meters—and found global average ocean warming of around 0.025°C per decade, slightly more than one tenth of a degree warming over 50 years.

The researchers say this kind of warming would not have been possible without human impacts.

Scientists believe that the oceans absorb around 90 percent of atmospheric heat—warning that as temperatures in the atmosphere rise, ocean warming will also become an increasing problem.

Ocean warming has been blamed for events such as coral bleaching. Scientists are also concerned about the impact of fish and plant species from warming oceans—particularly Krill which like to breed in particularly cold water near sea ice.

Sub-surface, deeper ocean warming was noticeably less than the observed Earth surface warming—mainly due to the relatively slow transfer of ocean surface warming to lower depths, according to the researchers.

The latest report, a collaboration from researchers across America, India, Japan and Australia is said to be the most comprehensive look at how the oceans have warmed to date.

Oil rigs around the world keep pulling crude oil out of the ground, but the global pandemic has sent shockwaves into the market. The supply is up, but demand has plummeted now that industry has ground to a halt, highways are empty, and airplanes are parked in hangars.

Under an agreement negotiated by community groups — represented by NRDC and the Pennsylvania Utility Law Project — the Pittsburgh Water and Sewer Authority (PWSA) will remove thousands of lead water pipes by 2026 in order to address the chronically high lead levels in the city's drinking water and protect residents' health.

So, they finally went and did it — the Trump administration just finalized a rule to undo requirements on manufacturers to improve fuel economy and reduce greenhouse gas emissions from new passenger cars and trucks. Even with the economy at the brink of a recession, they went forward with a policy they know is bad for consumers — their own analysis shows that American drivers are going to spend hundreds of dollars more in fuel as a result of this stupid policy — but they went ahead and did it anyway.

A blood test that screens for more than 50 types of cancer could help doctors treat patients at an earlier stage than previously possible, a new study shows. The method was used to screen for more than 50 types of cancer — including particularly deadly variants such as pancreatic, ovarian, bowel and brain.

Preliminary data from the Centers for Disease Control showed a larger number of young people coming down with COVID-19 than first expected, with patients under the age of 45 comprising more than a third of all cases, and one in five of those patients requiring hospitalization. That also tends to be the group most likely to use e-cigarettes.
