Volcanic activity related to Earth’s historical climate shifts

Volcanic activity related to Earth’s historical climate shifts

A new study, conducted by scientists from the University of Texas at Austin Jackson School of Geosciences, suggests the volcanic activity related to the plate-tectonic movements could have triggered climate changes in Earth's history. The research has…

Sunlight key to CO2 in Arctic, not microbes

Sunlight key to CO2 in Arctic, not microbes

A new study by scientists from Oregon State University, published this week in journal Science, concludes that sunlight and not bacteria is the key to triggering the production of CO2 from material released by Arctic soils. The finding is particularly importan

Watching Earth breathe: The seasonal vegetation cycle and carbon dioxide

Carbon dioxide is a naturally occurring gas in our atmosphere. View the seasonal cycle of carbon dioxide and the increase of carbon dioxide every year due to human activity. Embedded video from NASA Jet Propulsion Laboratory California Institute of

A new hypothesis on ocean acidification

A new hypothesis on ocean acidification

Since the beginning of the Industrial Revolution, the concentration of carbon dioxide in the atmosphere has been rising due to the burning of fossil fuels. Increased absorption of this carbon by the oceans is lowering the seawater pH (the scale which measures how

Arctic's spring phytoplankton blooms arrive earlier

Arctic's spring phytoplankton blooms arrive earlier

When summer comes to the Arctic, the tiny plants that feed the ocean's food chain form green blooms in the water. In some Arctic waters, the peak of this bloom has been arriving earlier every year since 1997, a study has found.

These areas, where peak bloom
