Earth’s oxygen levels rose and fell more than once hundreds of millions of years before the planetwide success of the Great Oxidation Event about 2.4 billion years ago, new research from the University of Washington shows.

Stronger westerly winds in the Southern Ocean could be the cause of a sudden rise in atmospheric CO2 in a period of less than 100 years about 16,000 years ago, according to a study published in Nature Communications.

A new study conducted at the University of Michigan reveals a previously unrecognized threat to monarch butterflies: Mounting levels of atmospheric carbon dioxide reduce the medicinal properties of milkweed plants that protect the iconic insects from disease.

Coastal cliffs from Santa Barbara to San Diego might crumble at more than twice the historical rate by the year 2100 as sea levels rise.

Nineteen inundation maps and detailed flood information from Hurricane Harvey are now available from the U.S. Geological Survey, in cooperation with the Federal Emergency Management Agency

Maria appeared as a well-organized storm on infrared NASA satellite imagery on July 9. Maria has fluctuated between typhoon and super typhoon strength and was a typhoon when NASA's Aqua satellite passed overhead.

Global fossil fuel emissions would have to be reduced by as much as 20% more than previous estimates to achieve the Paris Agreement targets, because of natural greenhouse gas emissions from wetlands and permafrost, new research has found.

Most of the carbon resulting from wildfires and fossil fuel combustion is rapidly released into the atmosphere as carbon dioxide. Researchers at the University of Zurich have now shown that the leftover residue, so-called black carbon, can age for millennia on land and in rivers en route to the ocean, and thus constitutes a major long-term reservoir of organic carbon. The study adds a major missing piece to the puzzle of understanding the global carbon cycle.

Fish that ‘farm’ their own patches of seaweed alter their ‘cropping’ practices under high CO2 conditions, researchers at the University of Adelaide in Australia have found.

Infrared imagery from NASA revealed two small area of strong storms remained in the remnants of Tropical Storm Beryl, moving into the eastern Caribbean Sea.
