NASA got an inside look at the heavy rainfall within developing Tropical cyclone Eliakim.
A new study finds that by 2150, the seemingly small difference between a global temperature increase of 1.5 and 2.0 degrees Celsius would mean the permanent inundation of lands currently home to about 5 million people, including 60,000 who live on small island nations.
Using data from NASA missions observing Earth, researchers at the University of California, Irvine have created new maps of the bed topography beneath a score of glaciers in southeast Greenland, thereby gaining a much better understanding of why some are undergoing rapid retreat and others are relatively stable.
Last year, 81 million people worldwide experienced severe food insecurity. About 80 percent of them live in Africa. While much of that food insecurity relates to civil war and violence in places like South Sudan and Nigeria, a good portion also stems from a sequence of five severe droughts that began in Ethiopia in 2015 and spread across parts of the continent in the ensuing three years.
Towering thunderstorms were found southeast of Tropical Cyclone Linda's center when the Global Precipitation Measurement mission or GPM core satellite passed overhead and analyzed the storm.
A growing network of lakes on the Greenland ice sheet has been found to drain in a chain reaction that speeds up the flow of the ice sheet, threatening its stability.
The impacts of global warming are felt especially in mountainous regions, where the rise in temperatures is above average. The repercussions of these changes are manifold and varied, from retreating glaciers to an increase in the frequency and intensity of snow avalanches. Researchers from the University of Geneva, Switzerland, has employed dendrochronology- the reconstruction of past disasters as recorded in growth series of trees- to disentangle the role of global warming in the triggering avalanches.
Infrared satellite data showed Tropical Cyclone 13P quickly developed powerful storms with very cold cloud top temperatures. NASA's Aqua satellite analyzed the system in infrared light to determine where its strongest storms were located.
When NASA-NOAA's Suomi NPP satellite passed over the South Pacific Ocean it captured a visible image of Tropical Cyclone Hola being torn apart by wind shear.
Early modern humans living in South Africa around 74,000 years ago prospered through the cataclysmic eruption of the Toba supervolcano in Sumatra. The Toba eruption was one of the Earth's most explosive volcanic events. The environmental effects of this event have been heavily debated, with some researchers having previously proposed that the eruption led to a worldwide volcanic winter that devastated contemporaneous human populations.
