Extended periods of volcanism known as flood basalt eruptions lead to volcanic winters, which are often followed by an extended period of warming. But it was more than just carbon dioxide that warmed the globe.

Saturn’s Powerful Winds Explain Changes in the Length of Its Day
Atmospheric winds moving at more than 7,000 kilometers per hour distort Saturn’s magnetic field, revealing why spacecraft have measured changes in the length of a day on the ringed world.
¿Cuánto tiempo permanecen las partículas de carbono negro en la atmósfera?
Investigadores descubren cómo el carbono negro evoluciona de partículas hidrofóbicas a sitios de nucleación de nubes, removiendo eventualmente las partículas que absorben calor del cielo.
Pollution Is Disrupting Rain Cycles in the Amazon
A team of researchers in Brazil and the United States uncovered the importance of the mechanism of oxidation—a process with the potential to affect climate and precipitation across the tropics.
Iodine-Laden Desert Dust Is Eating at Ozone Pollution
In a happy accident, scientists found a potential solution to an atmospheric chemistry mystery. Their findings could be a missing piece in the iodine cycle and in atmospheric models.
How Do Marine Gases Affect Cloud Formation?
By using novel aircraft measurements over the eastern North Atlantic Ocean, researchers shed light on the relationship between common marine biogenic gases and the microphysical properties of clouds.
Searching for Earthquakes in the Ionosphere
Earthquakes may release bursts of electrical energy that can be felt in the ionosphere, kilometers above Earth. The theory remains controversial, though.
Modeling Forest-Atmosphere Exchange
Studying the interactions between the atmosphere and forests is a key component of understanding forest ecosystems and the interplay between our atmosphere and the living world.
Measuring Carbon Ion Loss from the Martian Atmosphere
The flux, observed with NASA’s MAVEN spacecraft, is in line with models and 1–2 orders of magnitude lower than that of oxygen ions.
