The term smog is used to describe air pollution that develops when sunlight interacts with specific substances in the environment. Ozone is one of the main elements of photochemical smog. Ozone on the ground is damaging to human health, whereas ozone in the stratosphere shields the earth from da...
When talking about greenhouse gases, including methane and carbon dioxide, we also have to mention water vapour. It is a significant greenhouse gas, actually,which can hang around for yearsin the stratosphere. The water vapour then absorbs heat from the...
The ozone layer is found in the lower stratosphere about 20 to 30 kilometers (12-19 miles) above the earth's surface. While at ground level it is a pollutant, up there it fulfills the incredibly useful function of stopping too much ultra violet light getting through, soaking up about 97...
Near-zero growth in energy consumption is a recent phenomenon, and there is substantial uncertainty about the main drivers of consumption as the United States continues to recover from the latest economic recession and resumes more normal economic growth. EIA’s analysis in the AEO2015 includes seve...
” And if all continues to go as planned, the plane could take its first test flight in 2019. Once that happens, it may be used to bring rockets into the stratosphere before sending them into space. This method is generally considered a more cost-effective and efficient path to low-Earth...
Another popular film trope is that nuclear warfare leads to what is called a nuclear winter. That’s the idea of nuclear blasts injecting soot into the stratosphere andblocking out the sun. Could a massive bomb do that all by itself?

Over Antarctica very cold air falls from the stratosphere and then when at the surface falls downhill, it flows from the highest points. These highest points are the "Domes" as shown in the map below. These domes are also the coldest places in Antarctica, they were initially visited for ...

World View, which has a number of differentsky-based projectson the go, just scored a success with its Stratollite balloon system by completing a five-day flight, its longest yet in the stratosphere. Recommended Videos The Stratollite is an uncrewed and remotely controlled vehicle that’s tak...
