Scientists find new way global air churn makes particles

Posted by in categories: chemistry, climatology, particle physics

You can think of our atmosphere as a big chemistry set, a global churn of gaseous molecules and particles that constantly bounce off and change each other in complicated ways. While the particles are very small, often less than 1% of the thickness of human hair, they have outsized impacts. For example, particles are the seeds of cloud droplets, and the abundance of the particles changes the reflectivity and the amount of clouds, rainfall and climate.

Similarities Between Mars Soils and Newfoundland’s Subarctic Climate

“This shows that you need the water there in order to form these materials,” said Dr. Anthony Feldman. “But it needs to be cold, near-freezing mean annual temperature conditions in order to preserve the amorphous material in the soils.”


What was ancient Mars like? Was it warmer and wetter than it is today or cold and icy like present day Mars? This is what a recent study published in Communications Earth & Environment hopes to address as a team of researchers comprised of NASA scientists and academics investigated whether past climates on Mars mirrored today’s climate or were much warmer and had liquid water. This study holds the potential to help researchers better understand the climate history of Mars and whether it had the necessary conditions to support life as we know it.

For the study, the researchers analyzed X-ray data of soil material, which the researchers refer to as “X-ray amorphous material”, obtained from NASA’s Curiosity rover in Gale Crater on Mars and compared it to similar material at sites on Earth located in Newfoundland, California, and Nevada using the same X-ray methods employed by the Curiosity rover.

Spectrum services restored across Texas, spokesperson says

Posted by in category: climatology

AUSTIN (KXAN) — Spectrum has restored an outage that impacted users across Texas for about seven hours Tuesday, according to a company spokesperson.

“As of 7:30 p.m. Spectrum services have been restored in parts of Texas that were affected by a third-party infrastructure issue caused by the impact of Hurricane Beryl. We apologize for the inconvenience,” a spokesperson said in the latest update KXAN received via email Tuesday evening.

KXAN has followed up with Spectrum, asking for more details about what exactly this piece of infrastructure is and if it has a backup or reinforcement element.

Predicted Weakening of Ocean’s Overturning Circulation

Posted by in categories: biological, climatology, sustainability

“My work shows that we need to look more carefully at how ocean biology can affect the climate,” said Dr. Jonathan Lauderdale.


How will climate change influence the ocean’s circulation in the future? This is what a recent study published in Nature Communications hopes to address as a researcher from Massachusetts Institute of Technology (MIT) investigated how could hinder the ocean’s mechanisms of transferring carbon between the ocean floor and the planet’s atmosphere. This study holds the potential to help researchers, climate scientists, and the public better understand the long-term impacts of climate change and what steps that can be taken to mitigate them.

For the study, Dr. Jonathan Lauderdale, who is a Research Scientist in the Program in Atmospheres, Oceans, and Climate (PAOC) at MIT used models to challenge previous studies pertaining to the transfer of nutrients, specifically carbon, between the ocean floor and the Earth’s atmosphere, with an emphasis on a specific class of molecules called “ligands”. These previous studies dating back 40 years have hypothesized that weaker ocean circulation results in reduced levels of carbon dioxide being transferred to the atmosphere.

9000-year-old ‘Stonehenge-like’ structure discovered at the bottom of Lake Michigan

Posted by in category: climatology

Dr. Mark Holley, a distinguished underwater archaeology professor at Northwestern Michigan University, recently unearthed a prehistoric structure in the bay that has drawn comparisons to England’s iconic Stonehenge. Located approximately 40 feet beneath Lake Michigan’s surface, this remarkable find is poised to transform our understanding of the region’s ancient history.

The submerged stones, although smaller than those at Stonehenge, appear to be meticulously arranged. These stones, varying in size from basketballs to compact cars, form a meandering line over a mile long. Among them, a particularly notable rock stands out. It measures three and a half to four feet tall and five feet wide, and features a carving of a mastodon—a testament to an era when these majestic creatures roamed the Earth.

The stones are estimated to be around 9,000 years old, predating Stonehenge by about 4,000 years. This period follows the end of the Ice Age and the formation of Grand Traverse Bay, when the lake bed had not yet been submerged.

Texas Dam Under ‘Potential Failure Watch’

Posted by in categories: climatology, sustainability

In addition to storm surge along the Texas coast, Hurricane Beryl is expected to bring flooding to rivers and creeks inland. That’s raising new concerns about a dam that’s already damaged from flooding earlier this year. Watch the video to see where the problem is and how it could impact drinking water for millions of people. — Videos from The Weather Channel | weather.com

Inside The Secret Deals Between Tech Companies And Nuclear Power Plants

Posted by in categories: business, climatology, economics, nuclear energy, robotics/AI

Tech companies, including Amazon Web Services, are striking deals with U.S. nuclear power plants to secure electricity for their data centers, driven by the skyrocketing demands of artificial intelligence. This move promises 24/7 carbon-free power but stirs controversy, as it could divert existing energy supplies, raise prices, and increase reliance on natural gas. These nuclear-powered data centers might accelerate the AI race, but they also spark debates over economic development, grid reliability, and climate goals. Could this be the future of tech or a risky gamble with unforeseen consequences?

As reported by WSJ, tech businesses searching the country for electrical supplies have focused on one important target: America’s nuclear power facilities.

The owners of about one-third of the United States’ nuclear power reactors are in negotiations with technology companies about providing electricity to new data centers needed to satisfy the needs of an artificial intelligence boom.
