For a few weeks over the summer in 2011, teams of scientists from around the world converged on a small patch of ponderosa pine forest in Colorado to carry out one of the most detailed, extended survey of atmospheric chemistry ever attempted in one place, in many cases using new measurement devices created especially for this project. Now, after years of analysis, their comprehensive synthesis of the findings have been released this week.

While Hurricane Irma moves through the Caribbean islands toward South Florida with sustained winds of 185 miles per hour, forecasters are warning that two other major named storms have formed in the Atlantic Basin — Hurricanes Katia and Jose. It is the first time since 2010 that three hurricanes have been active in the region at the same time.

Satellite imagery from NASA's Aqua satellite and NASA-NOAA's Suomi NPP satellite have provided different data on the still Category 5 Hurricane Irma as it headed for the Turks and Caicos Islands.  

Satellite imagery from NASA's Terra and Aqua satellites showed that Hurricane Katia had not moved much, just about 30 miles in 16 hours.

Thunderstorms directly above two of the world’s busiest shipping lanes are significantly more powerful than storms in areas of the ocean where ships don’t travel, according to new research.

Researchers from the University of California, Irvine and NASA’s Jet Propulsion Laboratory have reported the first observation of sea level “fingerprints,” tell-tale differences in sea level rise around the world in response to changes in continental water and ice sheet mass. The team’s findings were published today in the American Geophysical Union journal Geophysical Research Letters.

Marine restoration, rather than protection, might be the most cost-effective solution for coastal marine ecosystems suffering from human activities, a new study has found.

Hidden in plain sight – that’s how researchers describe their discovery of a new genus of large forest tree commonly found, yet previously scientifically unknown, in the tropical Andes.

Hurricanes are the most violent storms on Earth. They form near the equator over warm ocean waters. Actually, the term hurricane is used only for the large storms that form over the Atlantic Ocean or eastern Pacific Ocean.

The Global Precipitation Measurement mission or GPM core satellite has been providing rainfall rates and cloud heights in tropical cyclones, and recently found towering thunderstorms that indicated strengthening in Tropical Storm Jose. Those "hot towers" were an indication the storm was strengthening and it later became a hurricane.
