Saturday Quote: When the universe is young and cute. Plus: Southern Ocean cooling trends explained
By analyzing the high-resolution cosmic microwave background, researchers were able to see simple models of the universe and eliminate many competing options. Credit: ACT Collaboration. ESA/Planck Collaboration One of the strangest facts in computer science is that it is really difficult to generate true random numbers. Anyway, on a computer. I can do it well: 173, 401, 530. It’s true…

Oceans emit sulfur, cooling the climate more than previously thought
Scientists have successfully quantified methanethiol emissions in the oceans on a global scale for the first time. Credit: Rafel Simó (ICM-CSIC) Researchers have for the first time quantified global emissions of sulfur gas produced by marine life, revealing that sulfur gas is cooling the climate more than previously thought, especially in the Southern Ocean. The study, published in the journal…

Cooling: Slowing ocean circulation could limit Arctic temperature rise
A map depicting the direction in which the AMOC transports warm water from the tropics to high latitudes. Credit: R. Currie, Woods Hole Oceanographic Institution/Science/USGCRP The Arctic is warming three to four times faster than the global average. But new research suggests that slowing major ocean currents could reduce projected Arctic warming by up to 2C by the end of…
