image for Chilling Forecast: Scientists Predict a Collapse of the Atlantic Ocean Current

Important ocean currents that redistribute heat, cold, and precipitation between the tropics and the northernmost parts of the Atlantic region will shut down around the year 2060 if current greenhouse gas emissions persist.

Using advanced statistical tools and ocean temperature data from the last 150 years, the researchers calculated that the ocean current, known as the Thermohaline Circulation or the Atlantic Meridional Overturning Circulation (AMOC), will collapse – with 95 percent certainty – between 2025 and 2095.

The researchers’ prediction is based on observations of early warning signals that ocean currents exhibit as they become unstable.

The researchers analyzed sea surface temperatures in a specific area of the North Atlantic from 1870 to the present day.

The Atlantic Meridional Overturning Circulation (AMOC) is part of a global system of ocean currents.

HIV Transmission Virtually Eliminated in Inner Sydney, Australia

Authored by

Use of HIV prevention tools increasing among gay and bisexual men in Australia, but younger men are more vulnerable to acquiring HIV.

In some countries, molecular analyses are being used to complement traditional HIV surveillance and public health efforts by defining HIV transmission groups, allowing rapid, tailored delivery of HIV prevention, testing and treatment services.

The study analysed HIV sequences collected from 2000 to 2020 from newly diagnosed people living with HIV in Victoria, Australia. »

Higher discounts likely to prompt India to buy more crude oil from UAE

Authored by

Higher discounts on crude oil offered by the United Arab Emirates (UAE) to wean India away from Russian crude may soon see Indian refiners ramping up purchases from the Gulf nation, officials at multiple refiners said.

“While discussions are underway, the UAE has offered discounts on crude, which will be more than that of the current level of Russian discounts.

But the level of discounts has continuously shrunk in 2023 as China snapped up large volumes of Russian crude. »
