Volcanic eruptions have been known to cool the global climate, but they can also exacerbate the melting of ice sheets, according to a paper published today in Nature Communications.

Researchers who analyzed ice cores and meltwater deposits found that ancient eruptions caused immediate and significant melting of the ice sheet that covered much of northern Europe at the end of the last ice age, some 12,000 to 13,000 years ago.

Vastly expanding sugarcane production in Brazil for conversion to ethanol could reduce current global carbon dioxide emissions by as much as 5.6 percent, researchers report in the journal Nature Climate Change.

An estimated 1.9 million U.S. homes could be flooded by 2100 if seas rise 6 feet in response to climate change, according to a new analysis by the real estate company Zillow. The affected properties are valued at $916 billion dollars and represent 1.8 percent of the country’s housing stock.

Rising sea levels and human activities are fast creating a "worst case scenario" for Native Americans of the Mississippi Delta who stand to lose not just their homes, but their irreplaceable heritage, to climate change.

Saline lakes around the world are shrinking in size at alarming rates. But what—or who—is to blame?

Rising sea levels caused by a warming climate threaten greater future storm damage to New York City, but the paths of stronger future storms may shift offshore, changing the coastal risk for the city, according to a team of climate scientists.

Now an extra-tropical cyclone over northern Japan, Lan was a typhoon when it made landfall just south of Tokyo over the weekend of Oct. 21 and 22. NASA's Aqua satellite and NASA-NOAA's Suomi NPP satellite provided imagery of the extra-tropical cyclone.

Until recently, glaciers in the United States have been measured in two ways: placing stakes in the snow, as federal scientists have done each year since 1957 at South Cascade Glacier in Washington state; or tracking glacier area using photographs from airplanes and satellites.

Forecasters at NOAA’s Climate Prediction Center released the U.S. Winter Outlook today, with La Nina potentially emerging for the second year in a row as the biggest wildcard in how this year’s winter will shape up. La Nina has a 55- to 65-percent chance of developing before winter sets in.

NOAA produces seasonal outlooks to help communities prepare for what's likely to come in the next few months and minimize weather's impacts on lives and livelihoods. Empowering people with actionable forecasts and winter weather tips is key to NOAA’s effort to build a Weather-Ready Nation.

Tropical rainforests continue to buffer wildlife from extreme temperatures even after logging, a new study has revealed.
