The world may warm by 1.5 degrees Celsius by the early 2030s, a climate change expert from The Australian National University (ANU) warns. Professor Mark Howden is a Vice-Chair of the Intergovernmental Panel on Climate Change (IPCC) and a contributing author to its Sixth Assessment Report , released today and which makes clear that global temperatures are … Continue reading Global Temperatures Likely To Rise In Next Decade (Geology)
Stanford-led expeditions to a remote area of Yukon, Canada, have uncovered a 120-million-year-long geological record of a time when land plants and complex animals first evolved and ocean oxygen levels began to approach those in the modern world. Hundreds of millions of years ago, in the middle of what would eventually become Canada’s Yukon Territory, … Continue reading Longest Known Continuous Record of the Paleozoic Discovered in Yukon Wilderness (Geology)
New study that includes contributions by Baylor planetary geophysicist Peter James, identifies previously unrecognized pattern of tectonic deformation on Venus A new analysis of Venus’ surface shows evidence of tectonic motion in the form of crustal blocks that have jostled against each other like broken chunks of pack ice. Published in the PNAS (Proceedings of … Continue reading Crustal Block Tectonics Offer Clues to Venus’ Geology, Study Finds (Planetary Science)
Analysis of 260 million years of major geological events finds recurring clusters 27.5 million years apart Geologic activity on Earth appears to follow a 27.5-million-year cycle, giving the planet a “pulse,” according to a new study published in the journal Geoscience Frontiers. “Many geologists believe that geological events are random over time. But our study provides statistical … Continue reading The Earth Has A Pulse — A 27.5-million-year Cycle Of Geological Activity (Geology)
A recent discovery by a research team that includes Kennedy College of Sciences Prof. Nelson Eby is shedding light on the debris created by an atomic blast, and it could set the stage for advances in materials research, including potential applications in energy, health care and nuclear forensics. The team, which also included researchers from the University of Florence … Continue reading Researchers Discover New Quasicrystal in Atomic Rock (Geology)
There has long been controversy about whether the world’s highest region, Tibet, has grown taller during the recent geological past. New results from the University of Copenhagen indicate that the ‘Roof of the World’ appears to have risen by up to 600 meters and the answer was found in underwater lava. The knowledge sheds new … Continue reading Geological Riddle Solved: Roof of the World Has Gotten Higher (Geology)
Findings will help better identify Earth-like planets that could sustain life Astronomers have identified more than 4,000, and counting, confirmed exoplanets — planets orbiting stars other than the sun — but only a fraction have the potential to sustain life. Now, new research from UBC’s Okanagan campus is using the geology of early planet formation … Continue reading UBCO Researcher Uses Geology to Help Astronomers Find Habitable Planets (Planetary Science)
A University of California San Diego engineering professor has solved one of the biggest mysteries in geophysics: What causes deep-focus earthquakes? These mysterious earthquakes originate between 400 and 700 kilometers below the surface of the Earth and have been recorded with magnitudes up to 8.3 on the Richter scale. Xanthippi Markenscoff, a distinguished professor in … Continue reading UC San Diego Engineering Professor Solves Deep Earthquake Mystery (Geology)
Rare earth elements are the gold of the 21st century: rare and highly prized all over the world. Most known and economically viable sources of rare earths are located in China, where more than 80 percent of them are refined. This has resulted in a near monopoly situation, with China dominating international trade, particularly in … Continue reading Rare Earths Outside China: FAU Researchers Identify New Deposits (Geology)
