A Wake-up Call from the Sun
A sudden burst of activity from the Sun in early September 2017 caused a wide range of space weather effects at Earth.
How Do Clouds React to Regional Warming?
Researchers illuminate how and why cloud feedbacks depend on spatial patterns of global warming.
California Floods Linked to Atmospheric Water Vapor “Rivers”
Narrow atmospheric streams of water vapor that deliver heavy rains are more commonly associated with floods and debris flows in northern California than with flash floods in southern California.
Diamonds Really Do Rain on Neptune, Experiments Conclude
Researchers subjected hydrocarbon samples in a laboratory to Neptune-like pressures. The samples, reminiscent of molecules found in the ice giant’s atmosphere, compressed into nanodiamonds.
VIDEO: The Weird, Wonderful Science Behind Titan’s Atmosphere
Scientists are baffled by a spacecraft’s detection of large molecules in a moon’s atmosphere.
Taking the Pulse of the Planet
How fast is Earth warming? Ocean heat content and sea level rise measurements may provide a more reliable answer than atmospheric measurements.
Mystery of the Ionosphere’s “Gyro Line” Solved
A new study provides an updated hypothesis to describe a unique radar signature from plasma waves high above Earth, correcting errors that had stood for decades.
New Data Record Extends History of Global Air Pollution
Researchers extend long-term aerosol records to the past 40 years by combining two existing algorithms to process satellite data over both land and sea.
Powerful Pacific Forces Disrupt the California Current
Scientists create a 66-year data record to shed light on the role of El Niño in the California Current System’s shifting temperatures.
