Before industrialization, the atmospheric carbon dioxide concentration was around 280 parts per million, as it had been in previous interglacials. Today, because of fossil-fuel burning it now stands at around 424 parts per million—higher than it has ever been since the end of the Pliocene epoch...
In order to provide a viable alternative to fossil fuels, many businesses are seeking to engineer alternative sources of energy that do not generate atmospheric carbon. Solar and wind power are now among the mostinexpensive sources of energy, and solar panels are affordable to U.S. homeowners at...
Air quality managers monitor six common air pollutants: particle pollution, ozone, carbon monoxide, sulfur dioxide, nitrogen dioxide and lead, with the first two comprising the bulk of pollutants. Thereporting periodis different for each air pollutant in the AQI, according to AirNow.gov. For examp...
Like the northern and southern lights, STEVE is a glowing atmospheric phenomenon, but it looks slightly different from its undulating auroral counterparts. "These emissions appear as a narrow and distinct arc, are typically purple in color and often include a green picket-fence structure that ...

The size of a wave is measured by its wavelength. The wavelengths of the light we can see range from 400 to 700 billionths of a meter (nanometers). The amount of energy in a light wave is proportionally related to its wavelength: shorter wavelengths have higher energy. Of visible light,...
Atmospheric Pressure Sensors: Track pressure changes that can indicate weather shifts. They are often used in logistics to optimize transportation routes or in building management to control indoor environments. Gas Sensors: Monitor the presence of harmful gases in industrial environments. These sensors ...

aCareful measurements of atmospheric carbon dioxide taken in the rarefied air atop Mauna Loa, Hawaii, and elsewhere have established that levels of the gas are rising steadily, from 316 parts per million in 1959 to 392 parts per million today. The question is how Earth’s great ecosystems resp...
carbon dioxide in the atmosphere, it is300 times more powerfulat warming the planet, and it remains in the atmosphere, holding in heat, for over a century. Today, atmospheric N₂O levels areabout 25% higherthan before the Industrial Revolution, and they’re still rising at an accelerating...
