4 days ago · Global warming, the phenomenon of increasing average air temperatures near Earth’s surface over the past one to two centuries, happens mostly in the troposphere, the lowest level of the atmosphere, which extends from Earth’s surface up to a height of 6–11 miles.
- Human activity affects global surface temperatures by changing Earth’s radiative balance—the “give and take” between what comes in during the day a...
- Continued global warming is expected to impact everything from energy use to water availability to crop productivity throughout the world. Poor cou...
- Polar bears live in the Arctic, where they use the region’s ice floes as they hunt seals and other marine mammals. Temperature increases related to...
3 days ago · The atmosphere may be Earth’s largest microbial ecosystem. It is connected to all of Earth’s surface ecosystems and plays an important role in microbial dispersal on local to global scales. Despite this grand scale, surprisingly little is understood about the atmosphere itself as a habitat.

8 hours ago · A G2 geomagnetic storm is set to collide with the Earth's atmosphere, resulting in auroras as far south as New York state and Idaho.
4 days ago · Turbulence is important because it mixes and churns the atmosphere and causes water vapour, smoke, and other substances, as well as energy, to become distributed both vertically and horizontally. Atmospheric turbulence near the Earth’s surface differs from that at higher levels.
2 days ago · Broadly, land–atmosphere interactions can be defined as feedback between the land and the atmosphere that affects the transport of the momentum, energy, and mass of various chemical species on the Earth’s surface [8,9]. This feedback has a significant influence on the near-surface atmospheric state at different spatiotemporal scales.
