Human-induced changes to Earth’s carbon cycle — for example, rising atmospheric carbon dioxide and ocean acidification — have been observed for decades.
The first detailed, high-resolution 3-D maps of Antarctic sea ice have been developed using an underwater robot.
Using ocean observations and a large suite of climate models, Lawrence Livermore National Laboratory scientists have found that long-term salinity changes have a stronger influence on regional sea level changes than previously thought.
Humans appear to have done a thorough job of contaminating the Earth’s rivers, oceans and atmosphere, says Rachel Nuwer. Is there anywhere pristine left on the planet?

Scientists from the UMass Dartmouth School for Marine Science and Technology drove up to the Fairhaven Shipyard before dawn Tuesday with a bright yellow, 6-foot torpedo-shaped object they call Blue.
Most of the concerns about climate change have focused on the amount of greenhouse gases that have been released into the atmosphere.
Earth is rapidly being wired with fiber-optic cables—inexpensive, flexible strands of silicon dioxide that have revolutionized telecommunications.
In 1966, 10 days after a U.S. plane carrying four nuclear bombs had run into another and crashed into Spain, the Department of Defense was not yet ready to admit that they were missing a bomb.
Using a first-of-its-kind, high-resolution numerical model to describe ocean circulation during the last ice age about 21,000 year ago, oceanographer Alan Condron of the University of Massachusetts Amherst has shown that icebergs and meltwater from the North American ice sheet would have regularly reached South Carolina and even southern Florida.
Nearly a quarter century ago, Greg Johnson was a freshly minted PhD in oceanography puttering north in the South Pacific Ocean.
