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.

High-altitude dust may disperse bacterial and fungal pathogens for thousands of miles, seeding far-flung ecosystems and potentially impacting human health

A recent discovery based on observations by the ESA/NASA Solar and Heliospheric Observatory, SOHO, shows that the gaseous layer that wraps around Earth reaches up to 630,000 km away, or 50 times the diameter of our planet.

Hurricane-strength storms in the Mediterranean could hit the region with increasing power by the end of the 21st century, growing to robust Category 1 strength, according to a new study in the AGU journal Geophysical Research Letters.

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.

Sea levels around the world have risen by 1.7 millimeters (0.07 inches) on average each year since 1880, but in recent years, scientists have observed a rapid increase in sea level in the north Indian Ocean. Tide gauge records and other datasets reveal the pace of sea level rise in the north Indian Ocean has accelerated to 3.1 millimeters (0.12 inches) per year within the last three decades. The accelerating sea level rise has confounded scientists but new research claims weakening of South Asian monsoons may be to blame.

A team of scientists led by postdoctoral researcher Takatoshi Sakazaki, from the University of Hawaiʻi at Mānoa’s International Pacific Research Center (IPRC), has analyzed satellite-based observations and computer model simulations of tropical rainfall variation throughout the day in an effort to determine the root cause of the temporal patterns. Their results, accepted for publication in Geophysical Research Letters, a journal of the American Geophysical Union, show that daily tropical rainfall distribution is significantly shaped by heating of the upper atmosphere.

Wildfires can perpetuate mercury contamination by releasing it from soil and plants and spreading it through smoke and ash. It doesn’t take much heat to convert mercury to a gas.

New research finds that as the climate warms, Earth’s atmosphere could trap more volcanic and plumes in the troposphere, the lower part of the atmosphere where weather happens. Volcanic aerosols that stay in the troposphere get washed out by precipitation in days or weeks.

The phrase “tipping point” passed its own tipping point and caught fire after author Malcolm Gladwell’s so-named 2000 book. It’s now frequently used in discussions about climate change, but what are “climate tipping points”? And what do they mean for society and the economy?
