NASA's P-3 research plane begins flights this month through both clouds and smoke over the South Atlantic Ocean to understand how tiny airborne particles called aerosols change the properties of clouds and how they influence the amount of incoming sunlight the clouds reflect or absorb.
Drought-stricken areas anxiously await the arrival of rain. Full recovery of the ecosystem, however, can extend long past the first rain drops on thirsty ground.
According to a study published August 10 in Nature, the length of drought recovery depends on several factors, including the region of the world and the post-drought weather conditions. The authors, including William Anderegg of the University of Utah, warn that more frequent droughts in the future may not allow time for ecosystems to fully recover before the next drought hits.

One hundred small streams in the Midwest were tested for pesticides during the 2013 growing season and found to contain, on average, 52 pesticides per stream
More than 180 pesticides and their by-products were detected in small streams throughout 11 Midwestern states, some at concentrations likely to harm aquatic insects, according to a new study by the U.S. Geological Survey.
University of Florida scientists discover cause of Atlantic coastline’s sea level rise hot spots.
July is the hallmark of summer in the United States. Long days, intense sun and high humidity typically make it the hottest month of the year. The heat can also trigger flash droughts, wildfires and summer storms. This July didn’t disappoint.
Here’s how July and the year to date fared in terms of the climate record.
Researchers at Newcastle University found that European sea bass experienced higher stress levels when exposed to the types of piling and drilling sounds made during the construction of offshore structures.
The fish also showed signs of being confused when they encountered a potential predator while exposed to these underwater noises. When researchers played recordings of piling sounds and mimicked an approaching predator, the seabass made more turns and failed to move away from the predator.
When exposed to drilling sounds the sea bass actively avoided these areas, spending more time in what the research team called the ‘safe zone’.
