Trees in California communities are working overtime. From removing carbon dioxide and pollutants from the air, intercepting rainfall and increasing property values, California's 173.2 million city trees provide ecosystem services valued at $8.3 billion a year. However, according to a recent study, more benefits could be realized if the Golden State's urban forests didn't have the lowest canopy cover per capita in the nation.

It’s tempting to believe that the devastating sequence of hurricanes in the Atlantic this year has blown in a new awareness of the risks of rising waters and increasingly powerful storms on our rapidly warming planet. In a rational world, the destruction wrought by these storms would inspire us to redouble our efforts to cut carbon pollution as quickly as possible and begin planning for an orderly retreat to higher ground. 

Agriculture is the economic engine that powers the Great Plains, the vast stretch of treeless prairie that covers parts of 10 states – and where the next drought can appear with little warning.

Now there’s a powerful new tool to help provide farmers and ranchers in the arid western United States critical early indications of oncoming droughts, and its name is EDDI.

Tropical Depression Dahlia was weakening into a remnant low pressure area when the Global Precipitation Measurement mission core satellite or GPM analyzed the storm's precipitation. GPM found the center devoid of rainfall and light rainfall to the east of center.  

NASA's Terra satellite passed over the Arabian Sea on Dec. 4 and found Tropical Cyclone Ockhi moving north as desert dust pushed into the region north of the storm.

An international team of scientists, led by the University of Leeds, has quantified the relationship between natural sources of particles in the atmosphere and climate change.

Their study, published today in Nature Geoscience, shows that the cooling effect of natural atmospheric particles is greater during warmer years and could therefore slightly reduce the amount that temperatures rise as a result of climate change.  

About 40 percent of northern Malaysian Borneo’s carbon stocks exist in forests that are not designated for maximum protections, according to new remote sensing and satellite mapping from Carnegie’s Greg Asner and his colleagues.

Moody’s Investors Service, one of the top credit rating agencies in the world, warned cities and states in the U.S. that unless they prepare for climate change, the agency could lower their credit ratings, making it harder for them to obtain low-interest bonds.

Droughts can grip the vast Sahel region of Africa for decades, dramatically altering the border where forest and savannahs give way to the Sahara Desert. Predicting those droughts is vital, but hard.

On Nov. 29 Tropical Cyclone Dahlia became the first tropical cyclone of the 2017-2018 Southwest Indian Ocean season. The Global Precipitation Measurement Mission or GPM core satellite provided forecasters with a look inside the clouds and into the rate rain was falling. Heavy rainfall has created the potential for landslides and NASA analyzed areas that may be subject.
