A group of researchers discovered so far the strongest evidence of a planetary thermostat counteracting the warming. The effect is caused by vast amounts of greenhouse gas, as the carbon dioxide gets absorbed into the rocky sediments. Discovery was made by…
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…
New study from Boston University, the University of Michigan and other institutions identifies a new, direct fingerprint of human activity on Earth as agricultural crops play a big role in seasonal swings of carbon dioxide in the atmosphere.Modern agricultural
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
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
Actress Darryl Hannah and NASA scientist James Hansen are just two of the more than 800 environmental protesters that have been arrested in front of the White House this week. The crowd has been demonstrating against the proposed Keystone Pipeline XL project, which invo
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
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
