The intense farming practices of the “Green Revolution” are powerful enough to alter Earth’s atmosphere at an ever-increasing rate, boosting the seasonal amplitude in atmospheric carbon
Air pollution from Asia has been rising for several decades but Hawaii had seemed to escape the ozone pollution that drifts east with the springtime winds. Now a team of researchers has found that shifts in atmospheric circulation explain the trends in Hawaiian ozone pollution.
Last year was one of the hottest twelve months on record, according to a new report from the National Oceanic and Atmospheric Administration (NOAA).
Atmospheric carbon dioxide levels have surpassed 400 parts per million (ppm) for the first time in human history, according to data released by the National Oceanic and Atmospheric Administration.
An international, NOAA-led research team took a significant step forward in understanding the atmosphereâ€™s ability to cleanse itself of air pollutants and some other gases, except carbon dioxide.
For over two centuries, meteorologists were puzzled by the observation that atmospheric pressure in the tropics peaks at 10 a.m. and 10 p.m. nearly every day. In the late 1960s, a theory was proposed that these surface pressure variations result from waves that are generated by the sun's heating of the upper atmosphere. The waves, called solar tides, propagate to the ground as they travel around the globe. Strong support for this theory has now been presented in a study by a US-Japan team of...

Researchers from the National Oceanographic and Atmospheric Administration Earth System Research Laboratory (ESRL) reported new data that shows a higher than usual average increase in carbon dioxide levels over the last 30 years.
