Gulf Stream System at its weakest in over a millennium  

Never before in over 1000 years the Atlantic Meridional Overturning Circulation (AMOC), also known as Gulf Stream System, has been as weak as in the last decades. Researchers compiled proxy data, reaching back hundreds of years to reconstruct the AMOC flow history. They found consistent evidence that its slowdown in the 20th century is unprecedented in the past millennium.

Understanding the evolution of SARS and COVID-19 type viruses  

As COVID-19 sweeps the world, related viruses quietly circulate among wild animals. A new study shows how SARS-CoV-2, the virus that causes COVID-19, and SARS-CoV-1, which caused the 2003 SARS outbreak, are related to each other. The work helps scientists better understand the evolution of these viruses, how they acquired the ability to infect humans and which other viruses may be poised for human spillover.

Extreme melt on Antarctica's George VI ice shelf  

Antarctica's northern George VI Ice Shelf experienced record melting during the 2019-2020 summer season compared to 31 previous summers of dramatically lower melt, a new study found. Using satellite observations that detect meltwater on top of the ice and within near-surface snow, the researchers found the most widespread melt of any season. Surface meltwater ponding is potentially dangerous to ice shelves because when these lakes drain, the ice fractures and may trigger ice-shelf break-up.
