NASA-NOAA's Suomi NPP passed over newly formed Tropical Storm Ava and analyzed the storm in infrared light. Ava, the third tropical cyclone of the Southern Indian Ocean season formed off the coast of northeastern Madagascar on Jan. 3. 

A new report from the National Academies of Sciences, Engineering, and Medicine calls for an international, multi-institutional comprehensive campaign of research, observation, and analysis activities that would help improve understanding and prediction of the Gulf of Mexico’s Loop Current System (LCS).  The position, strength, and structure of the LCS -- the dominant ocean circulation feature in the Gulf -- has major implications for oil and gas operations, hurricane intensity, coastal ecosystems, oil spill response, the fishing industry, tourism, and the region’s economy. 

 

In 1870, explorer Adolf Erik Nordenskiöld, trekking across the barren and remote ice cap of Greenland, saw something most people wouldn’t expect in such an empty, inhospitable landscape: haze.

Climate scientists often warn that rising CO2 levels in the atmosphere will cause an increase in the number and intensity of heat waves in many regions of the world. But a new study is cautioning that climate change will also significantly increase humidity, magnifying the effects of these heat waves and making it more difficult for humans to safely work or be outside.

The first tropical depression of the northwestern Pacific Ocean 2018 tropical cyclone season didn't waste any time forming after the first of the new year. Tropical Depression 1W formed just west of the Philippines in the Sulu Sea as NASA's Terra satellite passed overhead early on Jan. 2, 2018.

Over a quarter of the world’s land could become significantly drier if global warming reaches 2ºC - according to new research from an international team including the University of East Anglia.

Cookstoves are a central part of millions of homes throughout Asia: families often use readily available and cheap biofuels — such as crop chaff or dung — to prepare the food needed to survive.

Humans may be the dominant cause of global temperature rise, but they may also be a crucial factor in helping to reduce it, according to a new study that for the first time builds a novel model to measure the effects of behavior on climate.

Forty percent of the world’s 2.5 billion people live in coastal cities and towns. A team including Smithsonian marine biologists just released 25 years of data about the health of Caribbean coasts from the Caribbean Coastal Marine Productivity Program (CARICOMP). The study provides new insights into the influence of both local and global stressors in the basin, and some hope that the observed changes can be reversed by local environmental management.

As Tropical Cyclone Hilda was coming together in the Southern Indian Ocean the GPM satellite analyzed its rainfall from space. 

On December 26, 2017 at 3:06 a.m. EST (0806 UTC) the Global Precipitation Measurement mission or GPM core observatory satellite flew above northwestern Australia and measured rainfall as Tropical Cyclone Hilda was forming along the coast
