Are we in a "Sixth Extinction"?

Across Antarctica, some parts of the base of the ice sheet are frozen, while others are thawed. Scientists show that if some currently frozen areas were also to thaw, it could increase ice loss from glaciers that are not currently major sea-level contributors.

The technique helps us understand ice sheets right here on Earth -- and whether there could be life far, far beyond. (Source: Stanford Engineering)

A new study of tropical reef building corals shows these very long-lived animals are constantly changing and testing their genes – and some of these changes make it into the next generation. In this way a centuries-old coral might be a cauldron of genetic innovation, and it might help prepare them for climate change. (Source: Hopkins Marine Station)
