When NASA’s Aqua satellite passed over the U.S. Eastern seaboard, it captured an infrared image of Hurricane Chris that showed an eye staring back at the satellite. Chris is expected to continue generating heavy ocean swells along the U.S. East Coast and bring heavy rainfall to Newfoundland, Canada.

Hot temperatures continued to bake the U.S. last month, making it the third warmest June on record.

If you can predict the path of the jet stream, the upper atmosphere’s undulating river of wind, then you can predict weather – not just for a week or two, but for an entire season. A new Stanford study moves toward that level of foresight by revealing a physical link between the speed and location of the jet stream and the strength of the polar vortex, a swirl of air that usually hovers over the Arctic.

As the remnants of former tropical cyclone Beryl moved through the northern Leeward Islands and Puerto Rico, the Global Precipitation Measurement mission or GPM core satellite gathered important rainfall data on the storm.

When NASA's Aqua satellite passed over the northwestern Atlantic Ocean, an instrument aboard looked at Tropical Storm Chris' water vapor and cloud temperatures. Appropriately, the image showed a backwards "C" or comma shaped storm. The water vapor imagery indicated Tropical Storm Chris has the potential to generate heavy rainfall.  

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
