Solar geoengineering might work, but local temperatures could keep rising for years
Imagine a future where, despite efforts to reduce greenhouse gas emissions quickly, parts of the world have become unbearably hot. Some governments might decide to "geoengineer" the planet by spraying substances into the ...

Salt in sea spray found to be the reason for less lightning over tropical oceans
An international team of researchers has uncovered the reason that less lightning occurs over tropical oceans than over land. In their paper published in the journal Nature Communications, the group describes their multi-year ...
Discovering a new way by which aerosols rapidly form and grow at high altitude
Aerosol particles can form and grow in Earth's upper troposphere in an unexpected way, reports the CLOUD collaboration in a paper published today in Nature. The new mechanism may represent a major source of cloud and ice ...

Atmospheric turbulence may promote cloud droplet formation
Clouds form when water vapor in moist packets of air condenses onto atmospheric aerosols, such as particles of dust. The transition from dry particle to liquid water droplet is known as activation. The threshold for activation ...
