Life might thrive on the surface of Earth for an extra billion years
This schematic shows the relationship between the different physical and chemical processes that make up the carbonate-silicate cycle. In the upper panel, the specific processes are identified, and in the lower panel, the feedbacks associated are shown; green arrows indicate positive coupling, while yellow arrows indicate negative coupling.

Demand outstrips radar satellite supply
PARIS – Synthetic aperture radar constellations are expanding in response to growing public and private demand. In August, Finland-based Iceye launched four radar satellites. Japan’s Synspective sent aloft its fifth SAR satellite. And U.S.-based Capella Space added two satellites to its constellation. National security and defense organizations remain the dominant customers for SAR imagery and…

Sea Level Rise Uncertainty? Scientists Uncover Missing Piece in Current Predictions
Meltwater streaming across the top of the Greenland ice sheet. A study led by researchers at The University of Texas at Austin examines the flow and freezing of meltwater within old snow on the ice sheet, which can help improve estimate of sea level rise.
