The dissolved calcium carbonate then reacts with the CO2 in the water to form bicarbonate salts, locking the CO2 away. Adkins says that with a full-scale reactor, he aims to capture and store about half of a ship’s CO2 emissions. BAR Technologies/Cargill French company Airseas has developed the Seawing, which it says could help ships cut their carbon emissions by an average of 20%. A British company called Seabound, for example, makes a device that captures between 25% and 95% of a ship’s CO2 emissions. “We think that ships are actually going to be able to compete with underground CO2 storage,” he said.

CNN —Lunar dust collected by Apollo 17 astronauts in the 1970s has revealed that the moon is 40 million years older than previously believed. After landing on the moon on December 11, 1972, NASA astronauts Eugene Cernan and Harrison Schmitt collected rocks and dust from the lunar surface. A new analysis of that sample detected zircon crystals and dated them to 4.46 billion years old. “When the surface was molten like that, zircon crystals couldn’t form and survive. A lunar zircon grain is shown under a microscope.

☆ ‘Underground climate change’ is deforming the ground beneath buildings, study finds

CNN —A phenomenon that scientists have called “underground climate change” is deforming the ground beneath cities, a study conducted in Chicago has found. Technically known as “subsurface heat islands,” underground climate change is the warming of the ground under our feet, caused by heat released by buildings and subterranean transportation such as subway systems. “Deformations caused by underground climate change are relatively small in magnitude, but they continuously develop,” he said. “Calling it climate change seems like a bit of a coattail thing,” Archer, who was not involved with the study, said. The term “underground climate change,” however, was not coined for this study — it has been in use, and the phenomenon a subject of research, for some time.

☆ How an oil fracking boom to bust startup plans to thrive in the climate change era

And in a way, Duncan thought the science wasn't a good match for the blunt process of oil and gas drilling. The Covid downturn in 2020 capped close to a decade of a bear market for oil and culminated in the negative spot prices in the oil market in May 2020. Oil and gas was changing from a growth business to a value business, and oil company management were much more focused on fiscal discipline. That concentration of equipment and infrastructure's resulting reduced costs was not good for an oil services company. And there have been a lot of surprises along the way – how the shale boom became its biggest business, followed by how quickly the science became commoditized in the oil market.
