As expected, tropical cyclone Owen recently intensified as it moved over the Gulf of Carpentaria and NASA and the Japan Aerospace Exploration Agency's GPM core satellite found very heavy rainfall occurring within the revived storm. The storm has made a U-turn in the Gulf and is now headed back to Queensland.
An infrared look by NASA's Aqua satellite found intense storms around the center of the recently revived Tropical Cyclone Owen.
More and more rainfall extremes are observed in regions around the globe -- triggering both wet and dry records, a new study shows. Yet there are big differences between regions: The central and Eastern US, northern Europe and northern Asia have experienced heavy rainfall events that have led to severe floods in recent past. In contrast, most African regions have seen an increased frequency of months with a lack of rain.
The low pressure area formerly known as Tropical Cyclone Owen continued to organize and cross the southern Gulf of Carpentaria, Australia on Dec. 11. The Global Precipitation Measurement mission or GPM core satellite provided a look at the rainfall rates within the system.
The world's primary archive of tree ring data, which holds more than 52 million cost-free records spanning 8,000 years of history, has gotten a makeover by scientists from four countries committed to making science more accessible. The International Tree Ring Data Bank, developed in 1974 and populated by hundreds of contributing scientists and agencies, had only been used for a handful of studies at a global scale due to inconsistent data accessibility and formatting.
The remnants of Tropical Cyclone Owen have been lingering in the Southern Pacific Ocean for days. On Dec. 10, 2018 the storm finally appeared more organized on satellite imagery providing forecasters with a strong indication that it may be reborn as a tropical cyclone. NASA-NOAA's Suomi NPP satellite passed over the Gulf of Carpentaria and saw the storm.
Urban areas are warmer than the adjacent undeveloped land, a phenomenon known as the urban heat island effect. A new interactive map developed by Yale researchers gives us the most detailed look yet at these 'urban heat islands' across the world.
The production of chlorofluorocarbons, which damage the ozone layer, has been banned as far as possible. However, other substances can also tear holes in the ozone layer in combination with ice particles, such as those found in clouds. Researchers at Ruhr-Universität Bochum, the University of Duisburg-Essen and Friedrich-Alexander-Universität Erlangen-Nürnberg have discovered a possible mechanism for this. They describe it in the journal Physical Review Letters on Nov. 13, 2018.
Global carbon emissions are set to hit an all-time high in 2018. A projected rise of more than 2 percent has been driven by a solid growth in coal use for the second year in a row, and sustained growth in oil and gas use. But the research team say energy trends are changing and that there is still time to address climate change if efforts to curb carbon emissions rapidly expand in all sectors of the economy.
New Mexico contains hundreds of historic uranium mines. Although active uranium mining in the state has ceased, rates of cardiovascular and metabolic disease remain high in the population residing close to mines within the Navajo Nation. According to a new study in ACS' journal Environmental Science & Technology Letters, inhaled uranium in dusts from the mines could be a factor.
