An annual analysis of air samples collected at remote sites around the globe that is tracking a continued decline in the atmospheric concentration of ozone-depleting substances shows the threat to the ozone layer receding below a significant milestone in 2022, NOAA scientists have announced.

First Underground Radar Images from Mars Perseverance Rover Reveal Some Surprises
After a tantalizing year-and-a-half wait since the Mars Perseverance Rover touched down on our nearest planetary neighbor, new data is arriving — and bringing with it a few surprises.
Climate Change May Have Doubled the Number of Houston Homes Flooded by Hurricane Harvey
If not for climate change, 2017’s Hurricane Harvey might have flooded half as many homes in the Houston area, a new study finds.
Signs of CO2 in a Planet Beyond Our Solar System
In a remarkable display of its precision and accuracy, the James Webb Space Telescope (JWST), a collaboration between NASA, the European Space Agency, and the Canadian Space Agency, has captured definitive evidence for carbon dioxide in the atmosphere of a gas giant planet orbiting a Sun-like star 700 light-years away.
An Extrasolar World Covered in Water?
An international team of researchers led by Charles Cadieux, a Ph.D. student at the Université de Montréal and member of the Institute for Research on Exoplanets (iREx), has announced the discovery of TOI-1452 b, an exoplanet orbiting one of two small stars in a binary system located in the Draco...
A New Concept for Low-Cost Batteries
Made from inexpensive, abundant materials, an aluminum-sulfur battery could provide low-cost backup storage for renewable energy sources.
New research tracks the history of manatees across Earth’s oceans
While only four species of slow-moving aquatic herbivores of the order Sirenia remain on Earth, many different kinds of sea cows lived over the past 47 million years. Sea cows have lived along the coasts of every continent but Antarctica, and at times numerous species coexisted. A new article has...
‘Dangerous’ and ‘extremely dangerous’ heat stress to become more common by 2100
Even if countries manage to meet the Paris Agreement goal of keeping global warming to 2 degrees Celsius, combinations of heat and humidity that are dangerous to humans will become more frequent by 2100. A new statistical analysis finds that the tropics could be exposed to dangerous levels of heat...
Climate change exacerbated hurricane Harvey’s flood damage, hitting low-income and Latinx neighborhoods disproportionately harder
New research shows that if it were not for the impact of climate change, up to 50 percent of residences in Houston's Harris County would likely not have been flooded by Hurricane Harvey five years ago. The study coincides with the fifth anniversary of Hurricane Harvey, a Category 4 hurricane...
Scientists develop new technique to reveal the hidden genome
Thousands of short RNA sequences that code for microproteins and peptides have been identified, opening new avenues for disease research and drug development.
