Changing ocean chemistry threatens to harm marine life
Fifty-five million years ago, Earth endured a period of rapid global warming, a shift so dramatic it altered ocean and atmospheric circulation, driving plankton in the seas and mammals on land to extinction. The event, called the Paleocene-Eocene Thermal Maximum, may have been caused by volcanic eruptions that flooded the atmosphere with billions of tons of carbon dioxide. Or, methane gas frozen beneath the sea on continental shelves could have destabilized, diffusing into the atmosphere where it was oxidized into CO2. ...

The carbon dioxide chronicles
Late scientist's work hailed as crucial in global warming fight
On the lobby walls of the National Academies building in Washington, D.C., icons of achievement in science, engineering and medicine are engraved in limestone and granite. There is a star map drawn by Galileo Galilei, a sketch of a light bulb by Thomas Edison and images of Charles Darwin's Galápagos Island finches. ...

By measuring methane in ancient ice, researchers hope to piece together clues from past climate shifts
On the western edge of Greenland, where the Jakobshavn ice fjord flows toward the sea, the story of Earth's climate is laid out like chapters in a book. ...

U.S. to honor top researcher of atmosphere
One day in the late 1980s, Charles David Keeling walked into his boss's office at UCSD's Scripps Institution of Oceanography and pointed to an odd blip on a graph showing steadily rising levels of carbon dioxide in the atmosphere. "Ed, do you know what that is?" he asked Edward Frieman, then director of Scripps. The blip, Keeling explained, revealed a slowdown in rising levels of carbon dioxide around the globe caused by a spike in oil prices - and a resulting fall in consumption - during the Iran-Iraq war from 1980 to 1988. ...
I've been a regular contributor at Yale Climate Connections since its debut in 2007. The website, which offers original reporting, analysis, and commentary on climate change, is published by Yale University.
When I was a science reporter at The San Diego Union-Tribune from 2002-2007, I wrote numerous articles about climate change. This page includes a few highlights.
