A new modeling study led by two NOAA researchers highlights the vast challenges and potentially damaging consequences of solar geoengineering actions large enough to ward off extreme warming by the end of the 21st century.

Trust, safety and security are the most important factors affecting passengers’ attitudes towards self-driving cars.

Oxygen is essential for the development of higher life. However, it was hardly present in the oceans of the young Earth.

A recent study analyses data collected at 44 of the darkest places in the world, including the Canary Island Observatories, to develop the first complete reference method to measure the natural brightness of the night sky using low-cost photometers.

A new study from McGill University suggests that some Icelandic killer whales have very high concentrations of PCBs (polychlorinated biphenyls) in their blubber.

Plants are unparalleled in their ability to capture CO2 from the air, but this benefit is temporary, as leftover crops release carbon back into the atmosphere, mostly through decomposition. 

New research indicates that the legendary Sargasso Sea, which includes part of the Bermuda Triangle and has long featured in fiction as a place where ships go derelict, may actually be an important nursery habitat for young sea turtles.

Sea ice cover in the Southern Hemisphere is extremely variable, from summer to winter and from millennium to millennium, according to a University of Maine-led study. Overall, sea ice has been on the rise for about 10,000 years, but with some exceptions to this trend.

A new study led by scientists at the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science tracked large sharks in Miami and The Bahamas to understand how these migratory animals respond to major storms, like hurricanes.

Lightning bolts break apart nitrogen and oxygen molecules in the atmosphere and create reactive chemicals that affect greenhouse gases.
