Is Clear Air Turbulence becoming more common?
In recent years there has been a noticeable uptick in publicized incidents of turbulence affecting commercial aircraft. These events, sometimes unexpected and severe, have led to passenger injuries, emergency landings, and a recent rare fatality. Turbulence can be caused by a variety of factors, from the mixing of air…

Fastest rate of natural carbon dioxide rise over the last 50k years
CORVALLIS, Ore. – Today’s rate of atmospheric carbon dioxide increase is 10 times faster than at any other point in the past 50,000 years, researchers have found through a detailed chemical analysis of ancient Antarctic ice. The findings, just published in the Proceedings of the National Academy of Sciences, provide…

ESO telescope captures the most detailed infrared map of the Milky Way
Astronomers have published a gigantic infrared map of the Milky Way containing more than 1.5 billion objects ― the most detailed one ever made. Using the European Southern Observatory’s VISTA telescope, the team monitored the central regions of our Galaxy over more than 13 years. At 500 terabytes of data, this is the…
