An uprecedented belt of brown algae stretches from West Africa to the Gulf of Mexico—and it’s likely here to stay. Scientists at the University of South Florida in St. Petersburg's College of Marine Science used NASA satellite observations to discover and document the largest bloom of macroalgae in the world, dubbed the Great Atlantic Sargassum Bel

There are several wildfires burning in Arizona as the wildfire season in the West begins in earnest.

Month: January 2013

Unusual Cold in China and Northeast Asia

Between late November 2012 and early January 2013, China recorded its lowest temperatures in 28 years. In northeastern China, air temperatures dipped to -15.3°Celsius (4.5°Fahrenheit), according to the state news agency Xinhua. Frigid temperatures and blizzards stranded air and rail passengers, killed roughly 180,000 cattle, and forced authorities to open hundreds of shelters. Read more

Air Quality Suffering In China

Beijing Smog

Residents of Beijing and many other cities in China were warned to stay inside in mid-January 2013 as the nation faced one of the worst periods of air quality in recent history. The Chinese government ordered factories to scale back emissions, while hospitals saw spikes of more than 20 to 30 percent in patients complaining of respiratory issues, according to news reports.

Intense Bushfires in Tasmania

In January 2013, intense bushfires blazed in Tasmania, an island south of Australia. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured this image showing numbers fires burning across the island on January 7, 2013. Red outlines indicate hot spots where MODIS detected unusually warm surface temperatures associated with fires. Read more.

Dust Dominates Foreign Aerosol Imports to North America

Dust Moving West of Sea of Japan

NASA and university scientists have made the first measurement-based estimate of the amount and composition of tiny airborne particles that arrive in the air over North America each year. With a 3-D view of the atmosphere now possible from satellites, the scientists calculated that dust, not pollution, is the main ingredient of these imports.Read more.
