Why extinctions ran amok in ancient oceans, and why they slowed down

Not long after the dawn of complex animal life, tens of millions of years before the first of the “Big Five” mass extinctions, a rash of die-offs struck the world’s oceans. Then, for reasons that scientists have debated for at least 40 years, extinctions slowed down. A new Stanford University study shows rising oxygen levels […]

Methane: Potential of an overlooked climate change solution

Earlier this month, President Biden urged other countries to join the U.S. and European Union in a commitment to slashing methane emissions. Two new Stanford-led studies could help pave the way by laying out a blueprint for coordinating research on methane removal technologies, and modeling how the approach could have an outsized effect on reducing […]

Stanford Reveals Potential of an Overlooked Climate Change Solution

Analyses lay out a blueprint for speeding development of atmospheric removal and modeling how the approach could improve human health and have an outsized effect… The post Stanford Reveals Potential of an Overlooked Climate Change Solution appeared first on SciTechDaily.

Muskrats are a bellwether for a drying delta

The muskrat, a stocky brown rodent the size of a Chihuahua – with a tail like a mouse, teeth like a beaver and an exceptional ability to bounce back from rapid die-offs – has lived for thousands of years in one of Earth’s largest freshwater deltas, in northeastern Alberta, Canada. Today, this delta lies within […]

Is Venus still geologically active?

One day toward the end of this decade, a NASA spacecraft orbiting Venus is slated to begin sending radar signals through the planet’s thick, yellowish shroud of corrosive sulfuric acid clouds to measure the rise and fall of the planet’s hellish surface, centimeter by centimeter. Venus is often called Earth’s sister planet or twin because the […]

A climate change solution: invest in youth environmental education

Governments need to double down on investments and innovation in educating youth and communities about the environment if future generations are to be able to respond effectively and with appropriate urgency to the climate emergency, according to experts, including Nicole Ardoin, an associate professor at the Stanford Graduate School of Education. In the recent Environmental Education Research article(link is […]

Reinventing concrete

Concrete has given us the Pantheon in Rome, the Sydney Opera House, the Hoover Dam and countless blocky monoliths. The artificial rock blankets our cities and roadways, underlies wind farms and solar panel arrays – and will be poured by the ton in infrastructure projects supported by COVID recovery investments in the United States and […]

How does climate change drive migration, and what can be done about it?

In the face of a mounting humanitarian crisis at the U.S./Mexico border, the Biden administration has acknowledged climate change among the powerful forces pushing migrants from Central America. A $4 billion federal commitment to address the root causes of irregular migration acknowledges the need for adaptation efforts to help alleviate the situation. The challenge is […]

Flood risk’s impact on home values

Buyer beware: Single-family homes in floodplains – almost 4 million U.S. homes – are overvalued by nearly $44 billion collectively, or $11,526 per house on average, according to a new Stanford University-led study. Published in Proceedings of the National Academies of Sciences, the study suggests that unaware buyers and inadequate disclosure laws drive up financial risks that […]

Can extreme melt destabilize ice sheets?

Nearly a decade ago, global news outlets reported vast ice melt in the Arctic as sapphire lakes glimmered across the previously frozen Greenland Ice Sheet, one of the most important contributors to sea-level rise. Now researchers have revealed the long-term impact of that extreme melt. Using a new approach to ice-penetrating radar data, Stanford University […]
