Latest Earth's atmosphere Stories
Engineering our way out of global climate warming may not be as easy as simply reducing the incoming solar energy, according to a team of University of Bristol and Penn State climate scientists.
New research suggests that China's impressive feat of cutting Beijing's pollution up to 50 percent for the 2008 Summer Olympics had some help from Mother Nature.
Many of the particles in the atmosphere are produced by the natural world, and it is possible that plants have in recent decades reduced the effects of the greenhouse gases to which human activity has given rise.
Humans pump thousands of tons of vapor from the metallic element mercury into the atmosphere each year, and it can remain suspended for long periods before being changed into a form that is easily removed from the atmosphere.
Nitrogen derived from human activities has polluted lakes throughout the Northern Hemisphere for more than a century and the fingerprint of these changes is evident even in remote lakes located thousands of miles from the nearest city, industrial area or farm.
A Yale study examining the impact of aviation on climate change found that removing sulfur from jet fuel cools the atmosphere.
Scientists in the New York Center for Astrobiology at Rensselaer Polytechnic Institute have used the oldest minerals on Earth to reconstruct the atmospheric conditions present on Earth very soon after its birth.
NASA said on Monday that scientists have discovered lightning-made waves in Earth's atmosphere that leaked into space.
NOAA’s updated Annual Greenhouse Gas Index (AGGI), which measures the direct climate influence of many greenhouse gases such as carbon dioxide and methane, shows a continued steady upward trend that began with the Industrial Revolution of the 1880s.
Scientists braved ticks and a tiger to discover how human activities have perturbed the nitrogen cycle in tropical forests.
Atlantis launched from Kennedy Space Center on November 3, 1994 at 11:59 AM EST and landed at Edwards AFB on November 14 at 7:33 AM PST. The shuttle orbited 174 times at an altitude of 164 nautical miles at an inclination of 57 degrees and travelled 4.5 million miles. The mission lasted 10 days, 22 hours, 34 minutes, and 2 seconds. This mission further advanced efforts to collect data about sun's energy output, chemical makeup of the Earth's middle atmosphere, and how these factors affect...
Important things to know when it comes to weather are the terms that a meteorologist uses on the television, radio or on a weather website. The first term is Return flow. Sometimes you will hear a meteorologist use this term. The best way to understand this is to look at a weather map. When you see a High pressure center which is the blue H, look to the western side of that high pressure. This is where the warm moist air starts moving from the south back towards the north, which is why it...
Arctic haze is a phenomenon that occurs in the atmosphere at high latitudes in the Arctic due to air pollution. What distinguishes Arctic haze from haze found elsewhere, is the ability of its chemical ingredients to endure in the atmosphere for a longer period of time compared to other pollutants. Due to limited snowfall, rain, or turbulent air to displace pollutants from the polar air in the spring, Arctic haze can continue for more than a month in the northern atmosphere. Arctic haze was...
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...
Sky -- Although almost everyone have seen it, sky is hard to be defined precisely. Generally, sky is the space seen when one looks upward from the surface of a planet. Some people define sky as the denser gaseous zone of a planet's atmosphere. Clouds, rainbows and weather all occur amongst a planet's sky. In astronomy, the sky is divided into many regions, called constellations. The blue colour of the daytime sky results from the selective scattering of light rays. When the sunlight...
