A new study published in Analytical Chemistry challenges the idea that the Vinland Map is a medieval forgery, instead suggesting that its ink composition supports its authenticity. The research finds that the map's ink contains elements consistent with medieval production methods, raising doubts about the possibility of forgery.
A study suggests that diesel cars could warm the climate more over time than gasoline-powered vehicles, even with lower CO2 emissions. This is because soot from diesel engines has a shorter lifetime in the air and warms it more intensely.
A new report suggests that soot particles could have a significant impact on global warming, with potential policy implications. The study's findings introduce new uncertainty into climate models and shift responsibility for reducing pollution to developing nations like China and India.
A NASA study suggests that black carbon particles are responsible for changes in precipitation patterns over China, leading to increased flooding in the south and droughts in the north. The study used climate computer models and aerosol data to analyze the effects of black carbon on hydrologic cycles in China and India.
A recent deep-sea drilling expedition off Japan has revealed that vast areas of the Pacific Ocean were low in oxygen for periods of up to a million years each. The expedition, which lasted two months, uncovered evidence of global warming events more common than previously thought, with some occurring every thousand years.
A new NASA satellite sensor and field experiment reveals that aerosols can both cool the surface and warm the atmosphere. By analyzing data from the Indian Ocean Experiment (INDOEX) campaign, scientists found a regional cooling effect of up to three times greater than the warming effect of greenhouse gases.
Scientists at Virginia Tech have discovered a crucial mechanism behind the growth of calcium carbonate crystals, which help remove carbon dioxide from the atmosphere. The research could lead to novel materials with unique properties for medical and high-tech applications.
