Scientists at Northwestern University have made an astonishing discovery beneath Earth’s surface: a massive water reservoir about 700 km deep, locked inside mantle rock. Using data from 2,000 seismographs and seismic waves from 500 earthquakes, the team noticed the waves slowed down — a clear indication that water is being absorbed deep within the Earth. This hidden reservoir, stored in minerals within the mantle, could contain up to three times more water than all of Earth’s surface oceans combined. This revelation is transforming our understanding of Earth’s water cycle, showing that our planet’s oceans stretch far deeper than previously thought. This discovery not only reshapes how we view Earth’s geology, but it also raises new questions about the distribution of water within the planet and its potential impact on future studies of the Earth’s composition.

The publication of A prudent planetary limit for geologic #carbon storage in Nature is an important moment in the conversation about carbon capture and storage (#CCS). For decades storage has been discussed as if it were an almost limitless global sink, with estimates running from 10,000 to 40,000 gigatons of #CO₂ in sedimentary basins alone. Industry reports spoke confidently of 14,000 gigatons of capacity. Policy models often assumed that storage was effectively infinite and treated it as a backstop for both prolonged #fossilfuel combustion and for reversing overshoot scenarios later in the century. The new work cuts through that optimism by applying a risk-based filter to the entire map of global sedimentary basins. What emerges is a prudent planetary limit of about 1,460 gigatons of CO₂, or about 90% less than the technical figures that have dominated the discourse. The #methodology matters. Rather than counting pore space, the team layered in seismic risk, depth limits between 1 and 2.5 km, shallow water constraints of less than 300 m, 25 km buffers around projected urban areas, protected zones, polar circles, and contested maritime regions. The exercise moved CCS from the abstract world of geological potential to the real world of safety, environmental protection, governance, and public acceptance. It also revealed that only some countries retain significant safe storage potential after these exclusions are applied. The #UnitedStates, #Russia, #SaudiArabia, and #Australia remain robust. #Europe, #India, #Norway, and #Canada see sharp reductions. That uneven distribution has clear equity and #geopolitical implications. This is where I need to offer a mea culpa. In earlier writing I argued that the main limits to storage were likely to come from reservoir collapse, injection pressure, and permeability constraints. I was focused on injectivity and #geomechanics. Those concerns are real, but they represent only one slice of the risk picture. At the time I overstated them and did not account for the broader set of social, environmental, and governance filters that now define the prudent limit. The new paper has corrected the framing. It shows that while injectivity remains a rate constraint, the bigger story is that vast portions of the theoretical map are simply off limits if we take harm prevention and long-term safety seriously. The implications are significant. At best the full prudent limit of 1,460 gigatons could deliver about 0.7 °C of cooling if every molecule stored were dedicated to durable removals. If instead storage is allocated to offsetting continued fossil fuel combustion, the amount of achievable cooling falls proportionally. Most 2 °C pathways already use up to 2,000 gigatons of storage this century, which overshoots the prudent ceiling. Even some of the 1.5 °C scenarios that rely heavily on removals exceed it. This means that CCS cannot be both the lifeline for fossil fuels and the safety valve for overshoot.

Coersive Natural Chemical Reactions Natural chemical reactions can occur through coercion under various environmental conditions and factors that exert significant heat, pressure, or other influences that drive these reactions. Here are several natural factors that create the coercive conditions necessary for chemical reactions in nature: 1. Temperature - Geothermal Heat: https://lnkd.in/eFEEbav3 - Volcanic Activity: https://lnkd.in/e5RqXvCw 2. Pressure - Tectonic Activity: https://lnkd.in/eJBqgtC6 - Deep Earth Conditions: https://lnkd.in/ewi3Brjj 3. Concentration of Reactants - Nutrient Cycling: https://lnkd.in/ejV3mci9 - Atmospheric Composition: https://lnkd.in/exu4kdZ3 4. Catalysts and Environmental Factors - Lightning: https://lnkd.in/emUMBiJE - Biological Catalysts: https://lnkd.in/ejrvNPP7 5. Water Activity - Hydrothermals: https://lnkd.in/euSBmjUu - Soil Saturation: https://lnkd.in/esFAYKhB 6.

Natural Events: - Natural Disasters: https://lnkd.in/eXbw3BnE As seen above, Coercion in natural chemical reactions is driven primarily by physical and environmental conditions, including temperature, pressure, concentrations of reactants, and specific geological or biological catalysts. The interplay between these natural factors facilitates a wide range of significant geological, biological, and atmospheric processes that shape the Earth and its ecosystems. Understanding these factors provides insight into natural resource formation, nutrient cycling, and the dynamics of various ecological systems. While coercive natural chemical reactions are fundamental to maintaining ecological balance and supporting life on Earth, they can also have damaging effects on the environment, particularly under certain conditions. These reactions are complex and often interrelated, influencing various biogeochemical cycles and affecting climate change, air and water quality, and ecosystem health. The challenge lies in understanding and managing these natural processes to mitigate harmful impacts, especially in the context of anthropogenic climate change and environmental degradation. Integrating knowledge of these processes into conservation and environmental management strategies is crucial for promoting a more sustainable relationship between natural systems and human activity.

Expanding CO2 mineralization : more opportunity to scale permanent CO₂ storage. Geomar’s recent expedition explores how vast basalt formations beneath the seafloor in Norway can permanently mineralize CO₂, just as Carbfix has been proving on land in Iceland for over a decade. The potential is enormous: offshore basalt could theoretically store 40,000 gigatons of CO₂. Advanced geophysics, AI-driven analysis, and strong international collaboration are accelerating progress. For Carbfix, this is a natural extension of our journey, the same proven mineralization process, now with the possibility of scaling offshore. Collaboration between science and industry will be key to turning this potential into real climate impact. https://lnkd.in/dtvYAfxg #CarbonCapture #CarbonMineralization #MineralStorage #CarbonStorage #CCS #CCUS #ClimateAction #CleanTech #Sustainability #NetZero #Innovation #EnergyTransition #GreenTech #ClimateSolutions #Norway #Iceland #Germany #Klimawandel #Nachhaltigkeit #Netzwerken #Energiewende #Karbonfangst #Klimahandling #Nullutslipp #Bærekraft #Energiovergang

Volcanoes that blast gases high into the atmosphere not only change global temperatures but also influence flooding in unusual ways, Princeton researchers have found. Article in the journal Nature Geoscience, the researchers reported that major eruptions create distinct patterns of flooding depending on the location of the volcano and the dispersal of its plume. The patterns mostly divide along the line of the equator. When a volcano’s plume is generally contained in one hemisphere, flooding decreases in that hemisphere and increases in the other hemisphere. The pattern most strongly affects the tropical regions and demonstrates little to no effect on other regions. Volcanoes that create plumes affecting both hemispheres show a different pattern. These eruptions decrease flooding in the tropics in both hemispheres, while increasing flooding in arid regions.
