As devastating wildfires continue to rage in the western U.S. and Canada, a team of environmental engineers at Washington University in St. Louis have discovered that light-absorbing organic particulate matter, also known as brown carbon aerosol, in wildfire smoke loses its ability to absorb sunlight the longer it remains in the atmosphere.

A Zika virus outbreak in coastal Ecuador in 2016 was likely worsened by a strong El Niño and a magnitude 7.8 earthquake that struck the region in April, according to a new study.

The economically important big bluestem grass — a dominant prairie grass and a major forage grass for cattle — is predicted to reduce its growth and stature by up to 60 percent percent in the next 75 years because of climate change, according to a study involving Kansas State University researchers.

NASA scientists are once again on the hunt for greenhouse gases in the sky.

Infrared imagery from NASA’s Aqua satellite showed powerful thunderstorms around the center of Tropical Storm Ophelia with a band of thunderstorms stretching to the southwest, giving the storm the appearance of a comma.

Aside from inflicting devastating natural disasters on often vulnerable communities, climate change can also spur outbreaks of infectious diseases like Zika , malaria and dengue fever, according to a new study by researchers at the University of  Colorado Anschutz Medical Campus.

While strong seasonal hurricanes have devastated many of the Caribbean and Bahamian islands this year, geologic studies on several of these islands illustrate that more extreme conditions existed in the past. A new analysis published in Marine Geology shows that the limestone islands of the Bahamas and Bermuda experienced climate changes that were even more extreme than historical events. In the interest of our future world, scientists must seek to understand the complexities of linked natural events and field observations that are revealed in the geologic record of past warmer climates.

On Monday I woke to the terrifying smell of smoke. From my home south of San Francisco, I could see the entire Bay Area covered in a thick layer, obscuring the sun.

A team of scientists, led by British Antarctic Survey (BAS), is planning an urgent mission to investigate a mysterious marine ecosystem that’s been hidden beneath an Antarctic ice shelf for up to 120,000 years.  The researchers want to discover how this marine ecosystem will respond to environmental change in a climate-sensitive region.

The Colorado River tumbles through varied landscapes, draining watersheds from seven western states. This 1,450-mile-long system is a critical water supply for agriculture, industry and municipalities from Denver to Tijuana.
