Facing a climate crisis, we may someday spray sulfur dioxide into the upper atmosphere to form a cloud that cools the Earth, but suddenly stopping the spraying would have a severe global impact on animals and plants, according to the first study on the potential biological impacts of geoengineering, or climate intervention.
New research from a Florida State University scientist has revealed a surprising relationship between surging atmospheric carbon dioxide and flower blooms in a remote tropical forest.
NASA found heavy rainfall in Tropical Cyclone Berguitta as it closed in on Mauritius and Reunion Islands. On Jan. 18, NASA's Terra satellite captured an early morning visible image that showed the center of the storm just south of Mauritius and the storm blanketing both islands. Warnings were in effect for both islands. A tropical cyclone alert class 3 is in effect for Mauritius and La Reunion is on Orange Alert.
Can tumors teach us about animal evolution on Earth? Researchers believe so and now present a novel hypothesis of why animal diversity increased dramatically on Earth about half a billion years ago. A biological innovation may have been key.
Heavy rain surrounded Tropical Cyclone Berguitta as it continued to move toward the island of Mauritius in the Southern Indian Ocean. NASA calculated the rate in which rain was falling within the hurricane-strength storm in the Southern Indian Ocean.
In an attempt to better understand the urban environment and its components, scientists have discovered that sunlight causes chemical reactions in the dust found on Edmonton roads. 'We found that when you shine light on road dust, it produces a reactive form of oxygen called singlet oxygen,' said environmental chemist Sarah Styler. 'It acts as an oxidant in the environment and can cause or influence other chemical reactions.'
Aerosol indirect effect (AIE) can significantly affect climate change and is one of the largest uncertainties in climate change studies. To date, only a few AIE studies using satellite measurements have been carried out in China, and no such study has been done using ground-based measurements. The AIE can only be assessed accurately from aircraft or ground-based measurements. The first comprehensive investigation into the AIE over this polluted region is presented.
NASA's Terra satellite passed over the Southern Indian Ocean and saw Tropical Cyclone Berguitta moving southwest toward the island of Mauritius. A tropical cyclone alert class 2 is in effect for Mauritius.
NOAA's JPSS-1 satellite provided a visible image of the tropical storm after it made landfall along the Pilbara Coast in the northwestern part of Western Australia.
Secondary aerosol formation and rapid increases in aerosol particle sizes are believed to play important roles in haze formation. However, some simple but important questions remain unanswered, such as: How frequently and how fast do fine aerosol particles grow? And what affects their rates of growth?
