The destruction of atmospheric ozone can take place within newly forming Polar Stratospheric Clouds (PSCs), which serve as the battleground for manmade chlorofluorocarbons (CFCs) to attack and destroy ozone. These clouds form when clusters of frozen water "pick up" other atmospheric molecules such as methane, nitrogen oxides, and water molecules, similar to the way a snowball's girth increases as it rolls down a mountainside. Most previously established atmospheric models have assumed that a...

Estimates capitalize on instrumental measurements of CO2 in smokestacks and pollutants in the air by satellites and surface stations Atmospheric scientists at the Harvard School of Engineering and Applied Sciences (SEAS) and Nanjing University have produced the first "bottom-up" estimates of China's carbon dioxide (CO2) emissions, for 2005 to 2009, and the first statistically rigorous estimates of the uncertainties surrounding China's CO2 emissions. The independent estimates, rooted in...

When evaluating the historic contributions made by different countries to the greenhouse gasses found in Earth's atmosphere, calculations generally go back no further than the year 1840. New research from Carnegie's Julia Pongratz and Ken Caldeira shows that carbon dioxide contributions from the pre-industrial era still have an impact on our climate today. Their work is published in Environmental Research Letters. The burning of fossil fuels that came with industrialization released...

Brett Smith for redOrbit.com Cutting edge carbon capture technology is having quite the year so far as UK scientists said they have developed a "metal-organic framework" that works like a sponge, absorbing carbon dioxide from high pressure emissions. This latest breakthrough in clean energy technology, called NOTT-202, absorbs CO2 from the atmosphere by soaking in pressurized gasses and releasing these gases under lowered pressure while retaining the greenhouse gas, according to a...

Earth's Atmosphere

Earth's Atmosphere -- Earth's atmosphere consists of nitrogen (78.1%) and oxygen (20.9%), with small amounts of argon (0.9%), carbon dioxide (variable, but around 0.035%), water vapor, and other gases. The atmosphere protects life on Earth by absorbing ultraviolet solar radiation and reducing temperature extremes between day and night. 75% of the atmosphere exists within 11km of the planetary surface. Temperature and the Atmospheric Layers The temperature of the Earth's atmosphere...

call-note
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
