New geological data indicate that marine life is somewhat resilient to warming in the tropics. Chris Fokkema, earth scientist at Utrecht University, discovered that tropical algae were largely unaffected by a number of periods of global warming of up to 1.5 degrees Celsius in the distant past. These unicellar organisms form the basis of food webs and are generally very sensitive to rising temperatures. Previous studies of periods of even greater warming showed a dramatic decline in these organisms. “Somewhere beyond those 1.5 degrees, a tipping point occurs.”
Researchers from the Department of Earth Sciences, University of Oxford, have resolved a long-standing debate about the strength of the Moon’s magnetic field. For decades, scientists have argued whether the Moon had a strong or weak magnetic field during its early history (3.5 - 4 billion years ago). Now a new analysis – published today (26 February) in Nature Geoscience – shows that both sides of the debate are effectively correct.
A team co-led by University of Minnesota Twin Cities researcher Peter Makovicky and Argentinean colleague Sebastian Apesteguía has identified a 90-million-year-old fossil that provides the “missing link” for a mysterious group of prehistoric animals.
