Thawing permafrost in the Arctic is already unleashing methane and carbon dioxide to the atmosphere, exacerbating global temperature rise. As well adding to the climate crisis, this ground, which has been frozen for thousands of years, is becoming unstable and causing serious issues for local communities. For the first time, data from the Copernicus Sentinel-1 and Sentinel-2 missions along with artificial intelligence have been used to offer a complete overview of the Arctic to identify communities and infrastructure that will be at risk over the next 30 years.

The recent increase of Sphagnum mosses over wet aapa mires can be detected from Landsat satellite data. Aapa mire is a northern peatland complex type characterized by wet, sparsely vegetated fens in the central part, while margins are dominated by peat mosses. In recent years, the increase of Sphagnum mosses has been observed in many parts of Finland and some regions of North America. The

Radiocarbon records are critical to understanding the history of Earth's climate, magnetic field, and the Sun's activity, say researchers. In an article published in the journal Science, scientists have highlighted how recent advances in our knowledge of past radiocarbon levels are improving our understanding of climate processes, solar activity, geophysics and the carbon cycle. Unde

NASA has selected a new Earth science mission that will study the behavior of tropical storms and thunderstorms, including their impacts on weather and climate models. The mission will be a collection of three SmallSats, flying in tight coordination, called Investigation of Convective Updrafts (INCUS), and is expected to launch in 2027 as part of NASA's Earth Venture Program. NASA selected

The LIGO-Virgo-KAGRA Collaboration unveiled several studies that shed important new light on the nature of gravitational waves-ripples in time and space produced by merging black holes and/or neutron stars. They include a "census" of gravitational wave events to date and a new catalog of results from the second half of its third observing run (O3b), describing 90 gravitational wave events observ
