Electrification or hydrogen? Both have distinct roles in the European energy transition

Posted by in categories: climatology, economics, sustainability

A study, published in One Earth, is the first to analyze the interplay of electrification and hydrogen in EU climate neutrality scenarios at greater sectoral detail. The analysis shows higher potential for electrification and identifies a more confined deployment range for hydrogen-based energy than earlier studies.

“Previous research has shown that our power system can be transformed to renewable sources like wind and solar at low cost and low environmental impact. However, the next question is how this renewable electricity can be used to substitute in the buildings, industry and transport sectors. Our analysis shows that the direct use of electricity, for example, via and , is critical for a broad range of sectors, while the conversion of electricity to hydrogen is important only for few applications,” says Felix Schreyer, PIK scientist and lead author of the study.

Using the energy-economy model REMIND, PIK-scientists investigated plausible combinations of both strategies in EU energy system transformation pathways under different scenario assumptions.

Astrobiologists Suggest the Earth Itself May Be an Intelligent Entity

Posted by in categories: alien life, climatology, sustainability

A group of researchers have posed a fascinating — and downright mind bending — thought experiment: If a planet like Earth can be “alive,” can it also have a mind of its own?

The team published a paper exploring this question in the International Journal of Astrobiology. In it, they present the idea of “planetary intelligence,” which describes the collective knowledge and cognition of an entire planet.

Though it seems like something ripped off the screen of a Marvel movie, they believe that the concept might actually help us deal with global issues such as climate change, or even help us discover extraterrestrial life.

Vanadium research makes key advance for capturing carbon from the air

Posted by in categories: chemistry, climatology, sustainability

A chemical element so visually striking it was named for a goddess shows a “Goldilocks” level of reactivity—neither too much nor too little—that makes it a strong candidate as a carbon scrubbing tool.

The element is , and research by Oregon State University scientists, published in Chemical Science, has demonstrated the ability of vanadium peroxide molecules to react with and bind —an important step toward improved technologies for removing carbon dioxide from the atmosphere.

The study is part of a $24 million federal effort to develop new methods for , or DAC, of carbon dioxide, a that’s produced by the burning of fossil fuels and is associated with climate change.

Tesla Cybertruck to be featured at 2024 Chicago Auto Show

Posted by in categories: climatology, sustainability

The Tesla Cybertruck, together with its stablemates, will be displayed at the 2024 Chicago Auto Show, one of the United States’ most prolific automotive events. Updates from the organizers of the 2024 Chicago Auto Show indicate that the Cybertruck has arrived at the event’s venue, and it is ready for some visitors.

The Chicago Auto Show is held every February at the McCormick Place convention center, and it is generally regarded as the largest auto show in North America. The 2024 Chicago Auto Show will be held from February 10 through February 19, though a press preview is scheduled to start February 8. A “First Look for Charity” Gala is also scheduled on February 9, 2024.

Considering the prolific nature of electric vehicles in the United States today, it is no surprise that the 2024 Chicago Auto Show would be featuring a number of EVs. These include electric cars from veteran automakers such as the 2025 BMW i5, the 2025 Cadillac Escalade IQ, and the Ford F-150 Lightning Switchgear, to EVs from newcomers like the Lucid Air.

SpaceX launches NASA’s PACE mission, Earth’s climate guardian satellite

Posted by in categories: climatology, satellites

The SpaceX Falcon 9 rocket successfully launched NASA’s newest Earth-observation satellite, the PACE (Plankton, Aerosol, Cloud, Ocean Ecosystem) mission.


The rocket lifted off from Florida’s Cape Canaveral Space Force Station on Thursday, February 8, at 1:33 a.m. EST.

A volcano in Iceland is erupting again, spewing lava and cutting heat and hot water supplies

Posted by in category: climatology

GRINDAVIK, Iceland (AP) — A volcano in southwestern Iceland erupted Thursday for the third time since December, sending jets of lava into the sky, triggering the evacuation of the popular Blue Lagoon geothermal spa and cutting heat and hot water to thousands of people.

The eruption began at about 600 GMT (1 a.m. EST) along a three-kilometer (nearly two-mile) fissure northeast of Mount Sýlingarfell, the Icelandic Meteorological Office said. Several communities on the Reykjanes Peninsula were cut off from heat and hot water after a river of lava engulfed a supply pipeline.

SpaceX launches billion-dollar environmental research satellite for NASA

Posted by in categories: biological, climatology, education, satellites, sustainability

SpaceX launched an environmental research satellite for NASA early Thursday, a nearly $1 billion spacecraft that survived multiple cancellation threats and is now poised to shed new light on climate change and the complex interplay of heat-trapping carbon, aerosols and sea life on global scales.

The Plankton, Aerosol, Cloud, ocean Ecosystem mission — PACE — “will dramatically advance our understanding of the relationship between aerosols and clouds, and the global energy balance,” said Karen St. Germain, director of NASA’s Earth sciences division. “This is one of the biggest sources of uncertainty in our ability to model the climate.”

Solar geoengineering could start soon if it starts small

It’s possible to start a subscale deployment in just a few years. The climate effects would be tiny, but the geopolitical impact could be significant.

How a ‘bomb cyclone’ helped fuel California’s deadly storm

Posted by in category: climatology

The deadly storm that is walloping California with hurricane-force winds and record amounts of rainfall was fueled in part by the powerful weather phenomenon known as a “bomb cyclone,” according to the National Weather Service office in Monterey, Calif.

“For those keeping score, it also looks like it reached ‘bomb’ status,” a weather service forecast issued Sunday evening said.

The meteorologists who took over on Monday morning clarified that their colleagues were talking about “Bomb, meaning the intensity of the low pressure, not bomb meaning awesome.”

Algae Growth Linked to Atmospheric Dust: Insights from Pioneering Research

Posted by in categories: climatology, computing, sustainability

Dr. Janice Brahney: “Only recently have we started to see troubling outbreaks of toxic algal blooms in mountain environments. So, these changes are happening fast and are really concerning. It’s important we get to the bottom of this.”


What impact does atmospheric dust have on algae? This is what a recent study published in Global Change Biology hopes to address as a team of researchers from Utah State University (USU) investigated how increased dust concentrations in the Earth’s atmosphere could lead to larger algae blooms, impacting life on both land and in the oceans. This study holds the potential to help scientists better understand the acceptable amounts of dust and algae on the Earth and their impact on aquatic life, specifically in mountain ranges across the globe. The reason mountain headwater regions were the focus of the study was because they provide approximately 50% of the world’s population with fresh water.

“Only recently have we started to see troubling outbreaks of toxic algal blooms in mountain environments,” said Dr. Janice Brahney, who is an associate professor in the Watershed Sciences Department at USU and a co-author on the study. “So, these changes are happening fast and are really concerning. It’s important we get to the bottom of this. Toxic blooms in mountain lakes like the ones we’ve seen recently in remote mountain lakes are unprecedented.”
