Clouds on Venus race across the sky at speeds of more than 100 meters per second, driven by incompletely understood atmospheric dynamics. Credit: Kevin M. Gill, CC BY 2.0 Imagine the catastrophic ...

The way climate change affects thermodynamic signals, such as atmospheric temperatures, is relatively well understood. Its effects on atmospheric circulation, however, are more complex because the ...

Livestock like these Raya cattle represent a growing source of greenhouse gas emissions in Africa. Credit: Kelley Lynch/Flickr, CC BY-NC 2.0 The population of Africa, the second-largest continent in ...

Located at the intersection of South, Central, and East Asia, the massive Tibetan Plateau is often considered to be Earth’s “Third Pole.” A land of large glaciers, permafrost, and heavy snow, the ...

Warm water flowing into fjords and beneath ice shelves will continue to be a prime cause of glacial melting as global temperatures rise. This melting will, in turn, contribute to sea level rise and ...

Many ecosystems on Earth are affected by pulses of activity: temperature swings between seasons, incoming and outgoing tides, the yearly advent of rainy periods. These variations can play an important ...

During wildfires that blazed in Oregon and Washington in 2022, large plumes of smoke blew across the landscape and over the Pacific Ocean. Credit: NASA Earth Observatory The wrong kind of weather can ...

Clouds are an influential and complex element of Earth’s climate system. They evolve rapidly in time and exist over small spatial scales, but also affect global radiative balance and large-scale ...

Alfvén waves are fundamental to the dynamics of space plasmas. New space missions, sophisticated rocket campaigns, and advances in radar networks and computer modeling have grown our understanding of ...

In high-latitude Arctic fjords, warming seas and reduced sea ice are boosting seaweed growth. This expansion of seaweed “forests” could alter the storage and cycling of carbon in coastal Arctic ...

CalHeatScore provides a hyperlocal map of heat risk in California. Users can also overlay a map of public cooling centers (represented by blue triangles), including their addresses, hours, and contact ...

The Loop Current flows northward into the Gulf of Mexico through the Yucatán Channel and then exits eastward through the Straits of Florida. The current can be seen in this image from May 2010, which ...
