While extreme cold and snow often make headlines in the Northeast, by 2060, there will be far more record heat. Imagine the most sweltering day of the year. By 2060, you will experience that type of hot day for approximately three weeks of the year, assuming we don't substantially reduce greenhouse gas emissions. According to a Dartmouth study, of the rural Northeast counties represented, those in the bottom two lowest income quartiles will be hit hardest.
Australia's world-famous Great Barrier Reef is located in the Coral Sea, east of Queensland and on May 14, 2019 Tropical Cyclone Ann was moving over it. From their orbit in space, NASA's Terra and Aqua satellites passed over the Southern Pacific Ocean obtained visible and infrared imagery of the storm as it moved toward the Queensland coast.
An innovative use of instruments that measure the ocean near Antarctica has helped Australian scientists to get a clearer picture of how the ocean is melting the Antarctic ice sheet. Until now, most measurements in Antarctica were made during summer, leaving winter conditions, when the sea freezes over with ice, largely unknown.
NASA-NOAA's Suomi NPP satellite passed over the Southern Pacific Ocean and captured a visible image of Tropical Cyclone Ann in the Coral Sea, off the east coast of Queensland, Australia.
Topping the list of Australia's major crops, wheat is grown on more than half the country's cropland and is a key export commodity. With so much riding on wheat, accurate yield forecasting is necessary to predict regional and global food security and commodity markets. A new study published in Agricultural and Forest Meteorology shows machine-learning methods can accurately predict wheat yield for the country two months before the crop matures.
A years-long study that involved scientists and experiments at Berkeley Lab and UC Berkeley concludes that an odd assortment of particles found in beach sands in Japan are most likely fallout debris from the 1945 Hiroshima A-bomb blast.
A new analysis suggests that the moon is actively shrinking and producing moonquakes along thousands of cliffs called thrust faults spread over the moon's surface. The faults are likely the result of the moon's interior cooling and shrinking, causing the surface crust to shrivel and crack like a raisin's skin. The research, published in Nature Geoscience, combines data from NASA's Apollo and Lunar Reconnaissance Orbiter missions.
NASA's Aqua satellite used infrared light to analyze the strength of storms in Tropical Cyclone Lili as it moved through the Southern Indian Ocean. Infrared data provides temperature information, and the strongest thunderstorms that reach high into the atmosphere have the coldest cloud top temperatures.
A report describes the main features of the recently published World Ocean Experiment-Argo Global Hydrographic Climatology. This climatology is based on profile data from ships, Argo floats, and sensors attached to marine mammals. As an important deviation from the widely used climatologies produced previously by the National Oceanographic Data Center, the spatial interpolation was performed on local potential density surfaces, so that no 'artificial water masses' were created.
South Korea and southern-central Japan are frequently affected by extreme heat, and the extreme heat in these two regions tend to occur simultaneously. A scientific collaboration of climatologists examined the large-scale circulation leading to the concurrent extreme heat over South Korea and southern-central Japan.
