A new assessment of NASA’s record of global temperatures revealed that the agency’s estimate of Earth’s long-term temperature rise in recent decades is accurate to within less than a tenth of a degree Fahrenheit, providing evidence that past and future research is correctly capturing rising surface temperatures.

Researchers at NYU Abu Dhabi have discovered how the Maud-Rise Polynya that was initially spotted in Antarctica in 1974, reappeared in September 2017 at the same location.

New modeling indicates mineral dust from the Sahara is the biggest contributor to air pollution-related premature deaths on the African continent.

Some coal-fired power plants in the United States emit gases that may produce harmful compounds in drinking water and can have significant effects on the atmosphere, according to new research. A new study published in the Journal of Geophysical Research: Atmospheres, a journal of the American Geophysical Union, finds unexpectedly high levels of reactive bromine-containing chemicals in plumes emitted by coal-fired power plants not using a particular type of exhaust-cleaning technology.

Researchers at NYU Abu Dhabi, along with other global scientists, have identified a new mechanism by which warm dust travels from the Sahara Desert to the Arctic Circle, which has been proven to affect rising temperatures and ice melt in Greenland. Their findings highlight the role that the polar jet and associated atmospheric circulation plays in the transport of mineral dust from the Sahara Desert to the Arctic across the eastern side of the North Atlantic Ocean.

Two years after a research team discovered a previously unknown class of waves rippling continuously through the upper Antarctic atmosphere, they’ve uncovered tantalizing clues to the waves’ origins. The interdisciplinary science team’s work to understand the formation of “persistent gravity waves” promises to help researchers better understand connections between the layers of Earth’s atmosphere—helping form a more complete understanding of air circulation around the world.

Clouds are an inspiration to most of us, but a nightmare for climate scientists. Clouds are exceptionally complex creatures, and that complexity makes it difficult to predict how and where they’ll form – which is unfortunate, since those predictions are essential to understanding precipitation patterns and how our climate will change in the future.

A new study in the Journal of Geophysical Research: Atmospheres observes rare terrestrial gamma ray flashes produced by lightning strikes.

Using a sophisticated computer model, scientists have demonstrated for the first time that a new research approach to geoengineering could potentially be used to limit Earth’s warming to a specific target while reducing some of the risks and concerns identified in past studies, including uneven cooling of the globe.
