Particulate air pollution continues to cut global life expectancy by nearly two years as progress in some countries counterbalances worsening air quality in others, according to the Air Quality Life Index (AQLI).

In June this summer, a team of military personnel touched down on Alaska’s Colony Glacier with a somber mission: to recover newly unthawed wreckage and human remains from a fatal Cold War-era plane crash.

Current regulations on air pollution mainly focus on the mass of particles of a particular size range in a sample, and this has been used as a marker for their threat to human health.

Former Hurricane Douglas has encountered strong wind shear after passing the Hawaiian Islands and has now weakened to a tropical storm. 

Nowadays, life in the soil must contend with several problems at once. 

To remove carbon dioxide from the Earth’s atmosphere in an effort to slow climate change, scientists must get their hands dirty and peek underground.

Tree and plant cover has deteriorated considerably in some areas, while advancing in other areas that previously burned or used to be frozen.

The new projects look at food- and water-supply stability and how changes in human activity are affecting the environment.

NASA’s Aqua satellite provided infrared data on Tropical Depression Hanna while imagery from NASA-NOAA’s Suomi NPP satellite was used to create an animation showing its movement from Texas to Mexico.

Imagery from NASA’s Terra satellite was used to create an animation showing Douglas’ movement past the Hawaiian Islands.
