UWAB Faculty & Alumni Use Fossilized Raindrop Imprints to Explore Earth’s Ancient Environment

In a much-anticipated paper in Nature, UWAB faculty (Prof. Roger Buick & David Catling) and alum (Sanjoy Som, PhD ’10) have uncovered evidence — using 2.7 billion-year old, fossilized raindrop impressions — that an abundance of greenhouse gases in Earth’s ancient atmosphere likely caused warm temperatures that allowed the planet to retain liquid water… a crucial environmental component for the evolution of early life on our planet.
