Compared to the large ozone hole that forms over Antarctica each year, Arctic ozone loss has generally been much more limited. But in 2011, Arctic ozone declined to surprisingly low levels. What did climate have to do with it?
As of 2022, the warming effect of long-lived greenhouse gases in Earth's atmosphere had increased by 49% compared to 1990. Relative to pre-industrial times, today's atmosphere absorbs more than 3 extra watts of energy per square meter.
The tornado outbreak across the southern United States in late April 2011 was deadly, devastating, and record breaking. NOAA's "CSI" team is investigating the possible connections between global warming, natural climate patterns, and tornadoes.
Another Wintry Winter for the Eastern U.S.

On Hawaii’s Big Island, prevailing Pacific trade winds from the northeast bring more rainfall to northern & eastern slopes, leading to dramatic differences in vegetation on different sides of the island.
CalNex—an intense data collection campaign to characterize the complicated interactions of air quality and climate over California—used an array of instruments and platforms this spring for a close look at greenhouse gases and pollutants.
Twice a month, scientists send weather balloons into the air to collect data about the atmosphere, from the ground all the way up to the darkness of near space. Many gathered for the launch of last week’s balloon, which marked 30 years of NOAA water vapor measurements in Boulder.
Iceland’s Eyjafjallajökull Volcano roared to life on April 14, 2010, injecting billowing clouds of steam and volcanic ash into the atmosphere.
The Global Hawk research aircraft soars to hard-to-reach areas of the atmosphere to collect samples of trace gases and chemicals. Find out just how high the Global Hawk flies.
As the sun sinks below the horizon at the South Pole, NOAA researchers stationed at the bottom of the world settle in for six months of darkness. Throughout the Antarctic winter, the researchers will collect air samples to help maintain long-term records of trace gases, aerosols, and solar radiation.
