Researchers analyzed gas inclusions in 1.4-billion-year-old halite from Ontario to directly measure Mesoproterozoic atmospheric oxygen (~3.7% of modern) and CO2 levels (~10× preindustrial), revealing a milder climate than previously thought and offering new insight into Earth's ancient atmosphere during the so-called 'Boring Billion.'
The article highlights the extensive efforts and advanced technologies used in climate science, including fieldwork in remote locations, ice core analysis, cloud research, and satellite monitoring, to understand Earth's climate system and address global warming.
People in several US states were treated to a rare display of the Northern Lights, or aurora borealis, on Thursday night and Friday morning. The phenomenon was visible in Washington state, Montana, Wyoming, Minnesota, Wisconsin, South Dakota, North Dakota, and New York. The aurora was caused by a blast of solar energy that triggered geomagnetic storms, which in turn brought the aurora. The colorful aurora forms when particles flowing from the sun get caught up in Earth's magnetic field and interact with molecules of atmospheric gases.
