Levels of carbon dioxide in the atmosphere rise and fall each year as plants, through photosynthesis and respiration, take up the gas in spring and summer, and release it in fall and winter.
A new study led by the Georgia Institute of Technology provides further evidence of a relationship between melting ice in the Arctic regions and widespread cold outbreaks in the Northern Hemisphere. The study's findings could ...
The world lost record amounts of Arctic sea ice in 2012 and spewed out all-time high levels of greenhouse gases by burning fossil fuels, international climate scientists said Tuesday.
Atmospheric physicist Nick Gorkavyi missed witnessing an event of the century last winter when a meteor exploded over his hometown of Chelyabinsk, Russia. From Greenbelt, Md., however, NASA's Gorkavyi and colleagues witnessed ...
Western Australian mussel populations (Mytilus galloprovincialis) could potentially mix with translocated species from the eastern states according to a study by the WA Department of Fisheries and UWA.
Atmospheric carbon dioxide concentrations have crossed a new threshold, the UN's weather agency said Monday, highlighting the urgency of curbing manmade, climate-altering greenhouse gases.
Scientists have demonstrated a clear link between the 11-year sun cycle and winter weather over the northern hemisphere for the first time.
A study by scientists with the U.S. Forest Service, Harvard University and partners suggests that trees are responding to higher atmospheric carbon dioxide levels by becoming more efficient at using water.
They partly attribute the observed warming, and preceding cooling trends to ocean circulation changes induced by global greenhouse gas emissions and aerosols predominantly generated in the Northern Hemisphere from human activity.
