Among the most extreme planets discovered beyond the edges of our solar system are lava planets: fiery hot worlds that circle so close to their host star that some regions are likely oceans of molten lava. According to scientists, the atmosphere and weather cycle of at least one such exoplanet is even stranger, featuring the evaporation and precipitation of rocks, supersonic winds that rage over 5000 km/hr, and a magma ocean 100 km deep.
The biggest study yet of West Coast wildfire plumes shows how a smoke plume's chemistry changes over time. Results suggest current models may not accurately predict the air quality downwind of a wildfire.
Researchers with the University of Saskatchewan's Institute of Space and Atmospheric Studies are part of a global team that has found that the smoke cloud pushed into the stratosphere by last winter's Australian wildfires was three times larger than anything previously recorded.
POSTECH-Korea University joint research team develops a non-energy consuming radiative cooling material.
252 million years ago at the boundary between the Permian and Triassic epochs, Earth witnessed a mass extinction event that extinguished about three-quarters of all species on land and some 95 percent of all species in the ocean. Volcanic activity in today's Siberia has long been debated as a likely trigger of this event. Now, an international team of researchers provides for the first time a conclusive reconstruction of the key events that led to the mega-catastrophe.
Tropical Storm Nangka made landfall south of Haiphong, Vietnam and began to weaken. NASA's Aqua satellite revealed wind shear was affecting the storm as it continued to push inland.
Climate experts today released an assessment of carbon dioxide emissions by industry, transportation and other sectors from January through June, showing that this year's pandemic lockdowns resulted in a 9 percent decline from 2019 levels.
Sediments from a lake in the Canadian High Arctic allow climate scientists to extend the record of Atlantic sea-surface temperature from about 100 to 2,900 years. It shows that the warmest interval over this period has been the past 10 years. A team led by Francois Lapointe and Raymond Bradley in the Climate System Research Center at UMass Amherst analyzed "perfectly preserved" annual layers of sediment that accumulated in the lake on Ellesmere Island, Nunavut Territory.
Winter is on its way. And in this year of coronavirus, with it comes the potential for a second wave of COVID-19. Add in flu season and our tendency to head inside and close our windows to the cold, wet weather, and it appears the next several months are going to present us with new health challenges.
When permafrost thaws due to global warming, not only the greenhouse gases known to all, but also organic compounds are released from the soil. They may have a significant impact on climate change.
