How Does A Flood Become A Disaster? (Earth Science)

Review article summarizes state of research: One important factor is surprise What are the causes, patterns and effects of disastrous river flood? An international group of researchers led by GFZ hydrologist Bruno Merz has investigated this question in a review article published in the journal Nature Reviews Earth and Environment. The short answer: It’s complicated. … Continue reading How Does A Flood Become A Disaster? (Earth Science)

Lava Lamp Tectonics: How Giant Blobs of Subducted Sediment Float Up Through Deep Earth (Earth Science)

University of Wyoming professor has used computer modeling to propose that sand and mud subducted off the coast of California around 75 million years ago returned to the Earth’s crust by rising up through the mantle as enormous diapirs, like blobs in a lava lamp. These blobs are now found at the surface of the … Continue reading Lava Lamp Tectonics: How Giant Blobs of Subducted Sediment Float Up Through Deep Earth (Earth Science)

The Rise Of Oxygen On Early Earth Linked to Changing Planetary Rotation Rate (Earth Science)

The rise of oxygen levels early in Earth’s history paved the way for the spectacular diversity of animal life. But for decades, scientists have struggled to explain the factors that controlled this gradual and stepwise process, which unfolded over nearly 2 billion years. Now an international research team is proposing that increasing day length on … Continue reading The Rise Of Oxygen On Early Earth Linked to Changing Planetary Rotation Rate (Earth Science)

How Fire Today Will Impact Water Tomorrow? (Earth Science)

In 2020, Colorado battled the four largest wildfires in its history, leaving residents anxious for another intense wildfire season this year.  But last week, fires weren’t the issue—it was their aftermath. When heavy rains fell over the burn scar from the 2020 Cameron Peak fire, they triggered flash flooding and mudslides northwest of Fort Collins … Continue reading How Fire Today Will Impact Water Tomorrow?

How Climate Change And Fires Are Shaping The Forests of the Future (Earth Science)

Tracking future forest fires with AI As temperatures rise, the risk of devastating forest fires is increasing. Researchers at the Technical University of Munich (TUM) are using artificial intelligence to estimate the long-term impact that an increased number of forest fires will have on forest ecosystems. Their simulations show how Yellowstone National Park in the … Continue reading How Climate Change And Fires Are Shaping The Forests of the Future (Earth Science)

Have You Ever Wondered How Many Species Have Inhabited the Earth? (Earth Science)

Earth and environmental sciences professors explain why naming new species may be a never-ending journey. Ever since Swedish naturalist and explorer Carolus Linnaeus developed the uniform system for defining and naming species of organisms, known as binomial nomenclature (e.g. Homo sapiens for human beings), scientists have wondered if they will ever be able to predict the total … Continue reading Have You Ever Wondered How Many Species Have Inhabited the Earth?

New Type of Stellar Grain Discovered (Earth Science)

Unusual chemistry of grain could tell scientists more about the origin of Earth’s water Scientists have discovered a new type of star dust whose composition indicates that it formed during a rare form of nucleosynthesis (the process through which new atomic nuclei are created) and could shed new light on the history of water on … Continue reading New Type of Stellar Grain Discovered (Earth Science)

Changes in Earth’s Orbit Enabled the Emergence of Complex Life (Earth Science)

Scientists at the University of Southampton have discovered that changes in Earth’s orbit may have allowed complex life to emerge and thrive during the most hostile climate episode the planet has ever experienced. The researchers – working with colleagues in the Chinese Academy of Sciences, Curtin University, University of Hong Kong, and the University of … Continue reading Changes in Earth’s Orbit Enabled the Emergence of Complex Life (Earth Science)

Ancient Diamonds Show Earth Was Primed For Life’s Explosion At Least 2.7 Billion Years Ago (Earth Science)

A unique study of ancient diamonds has shown that the basic chemical composition of the Earth’s atmosphere which makes it suitable for life’s explosion of diversity was laid down at least 2.7 billion years ago. Volatile gases conserved in diamonds found in ancient rocks were present in similar proportions to those found in today’s mantle, … Continue reading Ancient Diamonds Show Earth Was Primed For Life’s Explosion At Least 2.7 Billion Years Ago (Earth Science)
