Some animal species respond to the emergence of new diseases by social distancing from other members of their species.
The big picture: Social distancing remains the most direct way to reduce the spread of disease, as we've discovered with COVID-19. The behavior may be so basic to survival that some animals do it instinctually — a model skeptical human beings might want to follow.
Greenland's ice sheet has melted beyond the point of no return, contributing to rising ocean levels, a new study published in the journal Nature Communications Earth and Environmentfinds.
Why it matters: Even if global warming were to stop imminently, annual snowfall that replenishes the ice sheet cannot keep pace with the ice that is flowing into the ocean from glaciers.
