The Mystery of the Missing Acorns

I was surprised to read in the Washington Post yesterday that oak trees from northern Virginia to Nova Scotia failed to produce any acorns this year


And the Next Species Predicted to Be Lost to Climate Change is…

…the antilopine wallaroo, a type of kangaroo that lives in wet, tropical areas of Australia

Ground Thaw

Geographer Christopher Burn explains why permafrost is thawing

A gray reef shark swims over corals in remote Kingman Reef in the Line Islands. Researchers believe that a large number of sharks is indicative of healthy reefs.

Deep Trouble

Coral reefs are clearly struggling. The only debate for marine scientists is whether the harm is being done on a local or global scale


Turning the Tide

Our oceans are in trouble, says Nancy Knowlton. But it's not too late to do something about it

Nudibranchs (seaslugs) are favorite with amateur divers. The advent of SCUBA diving and digital photography has revolutionized how we document and describe these soft-bodied, shell-less gastropods.

Species Explosion

What happens when you mix evolution with climate change?

"If global warming's worst predictions come true in 100 years," says Fabio Carrera, "the real issue is preserving Venice as a liveable place—not stopping the occasional tide from coming in."

Venice's Uncertainty

A new floodgate system should protect the city from high tides—unless climate change interferes
