CO2 puts heavier stamp on temperature than previously thought, analysis suggests
By Royal Netherlands Institute for Sea Research | June 24, 2024

nalysis.html
A doubling of the amount of CO2 in the atmosphere could cause an increase in the average temperature on Earth from 7 to a maximum of 14 degrees. This is shown in the analysis of sediments from the Pacific Ocean off the coast of California, by researchers at NIOZ and the Universities of Utrecht and Bristol. Their results were published in Nature Communications.
"The temperature rise we found is much larger than the 2.3 to 4.5 degrees that the UN climate panel, IPCC, has been estimating so far," said the first author, Caitlyn Witkowski.
The researchers used a 45-year-old drill core extracted from the bottom of the Pacific Ocean. "I realized that this core is very attractive for researchers, because the ocean floor at that spot has had oxygen-free conditions for many millions of years," said Professor Jaap Sinninghe Damsté, senior scientist at NIOZ and professor of organic geochemistry at Utrecht University.
"As a result, organic matter is not broken down as quickly by microbes and more carbon is preserved," Damsté said. He was also the supervisor of Witkowski, whose doctorate thesis included this research.
"CO2 over the past 15 million years has never before been examined from a single location," Witkowski said. The upper thousand meters of the drill core correspond to the past 18 million years. From this record, the researchers were able to extract an indication of the past seawater temperature and an indication of ancient atmospheric CO2 levels, using a new approach.
Derived temperature
The researchers derived the temperature using a method developed 20 years ago at NIOZ, called the TEX86 method. "That method uses specific substances that are present in the membrane of archaea, a distinct class of microorganisms," Damsté explains.
"Those archaea optimize the chemical composition of their membrane depending on the temperature of the water in the upper 200 meters of the ocean. Substances from that membrane can be found as molecular fossils in the ocean sediments, and analyzed to this day."
CO2 from chlorophyll and cholesterol
The researchers developed a new approach to derive past atmospheric CO2 content by using the chemical composition of two specific substances commonly found in algae: chlorophyll and cholesterol. This is the first study to use cholesterol for quantitative CO2 and the first study to use chlorophyll for this time period. To create these substances, algae must absorb CO2 from the water and fix it via photosynthesis.
Damsté said, "A very small fraction of the carbon on Earth occurs in a 'heavy form,' 13C instead of the usual 12C. Algae have a clear preference for 12C. However, the lower the CO2 concentration in the water, the more algae will also use the rare 13C. Thus, the 13C content of these two substances is a measure of the CO2 content of the ocean water. And that in turn, according to solubility laws, correlates with the CO2 content of the atmosphere."
Using this new method, it appears that the CO2 concentration dropped from about 650 parts per million, 15 million years back, to 280 just before the industrial revolution.
Stronger relationship
When the researchers plot the derived temperature and atmospheric CO2 levels of the past 15 million years against each other, they find a strong relationship.

Three million years ago, the atmosphere’s carbon-dioxide levels weren’t so different from those of today, but sea levels were dozens of meters higher. Looking that far back presents a foreboding peek into the future, as satellite records show that melting Antarctic ice sheets are on their way to bulking up this epoch’s oceans, too. The puzzle for scientists is that the climate models they create can’t seem to match what they see with their own eyes.
“Lots of people have been scratching their heads trying to figure out what is missing from our ice sheet models,” said Alex Bradley, an ice dynamics researcher at the British Antarctic Survey, part of the United Kingdom’s Natural Environment Research Council.
This week, two new papers in the journal Nature added to the growing pile of evidence that scientists’ models aren’t capturing a complete picture of Antarctica’s rapid deterioration. One study, published on Thursday, found that more than twice as much meltwater could be weighing on the surface of ice shelves, extensions of glaciers that float on the sea, than scientists previously thought. The study published on Tuesday identified a new potential tipping point: Where the land-anchored ice meets the sea, warming ice is creeping underneath, melting it from the belly up.
From above and below, Antarctica’s vault of ice, holding back almost 60 meters of potential sea level rise, seems more imperiled than ever. But neither of the dynamics detailed by these recent studies are used in climate models — potentially leading to an underestimation of how high seas might rise in coming decades.

Using copper to convert CO2 to methane could be game changer in mitigating climate change
By Rowan Hollinger | July 4, 2024

Carbon dioxide from the atmosphere can be transformed into methane and once the methane is used, any carbon dioxide released can be captured and "recycled" back into methane. This would create a closed "carbon loop" that does not emit new carbon dioxide into the atmosphere.

They would need a source of hydrogen to convert CO2 to CH4.
So, where does this H come from? Water?
Are we talking about electrolyzing water, again?
And what is the conversion efficiency?
I wish the article had more detail, bc everybody likes to publish whizbang papers, but nobody like to repeat experiments to make sure that it works and determine if it is scalable.
MORE DETAILS, PLEASE.

Tesla detailed the average battery-capacity retention per distance traveled of the Model 3 and Model Y cars with Long Range battery packs. For both models, the average battery capacity loss after 200,000 miles is 15%. In other words, the average capacity retention after that distance is 85%.
Longer battery life means EV drivers will save money, as they won't have to purchase a new battery replacement. According to data estimates from Tesla, Americans stop driving a car once it reaches about 200,000 miles. With the battery capacities noted in the 2023 Impact Report, Tesla batteries should not need to be replaced during the life span of the car.

The world of electric vehicles (EVs) might be on the brink of a dramatic shift thanks to a recent discovery from Nyobolt, a promising British startup focused on batteries.
This innovation could make the inconvenience of extensive battery-charging durations a thing of the past, bringing electric vehicle convenience closer to that of traditional gas-powered cars.
Headquartered in Cambridge, Nyobolt has recently made headlines with their novel 35kWh lithium-ion battery. The first live demonstration indicated that it could charge from 10% to 80% in just over four and a half minutes.
This is a significant leap from the usual 20 odd minutes spent on fast chargers like Tesla's Supercharger, and it's well on the way to the average gasoline fill-up time of two minutes.
"Our extensive research here in the UK and US has unlocked a novel battery technology that is ready and scalable right now. We are enabling the electrification of new products and services currently considered inviable or impossible," said Nyobolt CEO Sai Shivareddy.

Natrium Reactor
Terrapower's Natrium Project and the ARDP Partnership
TerraPower is building its first plant through a public-private partnership with the U.S. Department of Energy's (DOE) Advanced Reactor Demonstration Program (ARDP).
This program authorizes a 50/50 cost share and authorizes up to $2 billion for the Natrium project. TerraPower and partners will match this investment dollar for dollar. The first-of-a-kind cost for the Natrium demonstration plant will include the reactor design and licensing, codes and methods development, fuel development and qualification, and the design, construction and operation of two supporting facilities: the Natrium Fuel Fabrication Facility and Sodium Test and Fill Facility. The sodium facility will be used to test and demonstrate the performance of first-of-a-kind equipment prior to operations in the reactor plant.
https://www.terrapower.com/natrium/
The U.S. Nuclear Regulatory Commission (NRC) is currently engaged in pre-application activities interactions for the Natrium reactor. The Natrium design combines features from the previous GEH PRISM and TerraPower Traveling Wave designs. The proposed Natrium reactor is a 345 MWe pool type sodium fast reactor using HALEU metal fuel.

Why Bill Gates’ New Natrium Reactor is a Big Deal

You covered the thermal storage pretty well but left out some of the more interesting parts/advantages.
Natrium is a low-pressure/high-temperature reactor, this is the most important aspect of this technology. Low-pressure means no expensive forgings and containment structures that high-pressure water reactors need. This saves a lot of money and improves safety at the same time.
High-temperature allows for thermal storage but also separates the power conversion side of the plant from the nuclear side. All the equipment is off-the-shelf stuff that doesn't need to be nuclear certified. This saves a lot of money and allows you to start construction early, like you see in the thumbnail. You can't do this with a LWR.
High-temperature along with fast neutrons means much higher efficiency and later
waste burning. High-temperature also means cheap industrial process heat, something neither LWRs or renewables can provide. The demand for process heat is double that of electricity alone. This is a huge deal.
