Approximate depths of subsurface activities. Median (31 m) and 95th (130 m) percentile of water wells (Jasechko & Perrone, 2021); minimum depth of CCS in sedimentary basins (800 m) (Benson & Cole, 2008); shallow limit of oil and gas development (including injection and disposal; 600 m) (Lemay, 2008); geothermal (>2,000 m) (Nardini, 2022). The upper temperature limit for life (80–121°C) (Bar-On et al., 2018; Magnabosco et al., 2018) approximately corresponds to the lowest temperatures required for geothermal power generation (Nardini, 2022; Tester et al., 2021). Circulation of meteoric water occurs up to depths of a few km (McIntosh & Ferguson, 2021) but fluxes are small below 500 m and residence times range from tens of thousands to millions of years (Ferguson et al., 2023; Jasechko et al., 2017; Warr et al., 2021).

Human activities have an intense impact on Earth’s deep subsurface fluid flow – “We know more about the surface of Mars than we do about water, rocks, and life deep beneath our feet”

By Niranjana Rajalakshmi 23 April 2024 (University of Arizona) – The impact of human activities – such as greenhouse gas emissions and deforestation – on Earth’s surface have been well-studied. Now, hydrology researchers from the University of Arizona have investigated how humans impact Earth’s deep subsurface, a zone that lies hundreds of meters to several […]

A new surge in power use is threatening U.S. climate goals – “I can’t recall the last time I was so alarmed about the country’s energy trajectory”

By Brad Plumer 17 March 2024 (The New York Times) – Something unusual is happening in America. Demand for electricity, which has stayed largely flat for two decades, has begun to surge. Over the past year, electric utilities have nearly doubled their forecasts of how much additional power they’ll need by 2028 as they confront […]

OPEC leader tells members to block any COP28 climate summit deal to curb fossil fuels – “Reject any text or formula that targets energy i.e. fossil fuels rather than emissions”

By Lisa Friedman 8 December 2023 (The New York Times) – The head of the OPEC oil cartel, alarmed that nations gathered at the United Nations climate summit in Dubai are considering an agreement to phase out fossil fuels, has directed the group’s members to scuttle any deal that would affect the continued production and […]

Video: Honest Government Ad: COP31 🇦🇺 and the Pacific – “Let this major fossil-fuel exporter that’s cockblocked climate action for decades co-host a crucial summit with the most climate-vulnerable nations in the world while ignoring their pleas to stop harming them”

1 August 2023 (The Juice Media) – Hello. Bonjour. Ciao stronzi. Namaste. Ham maadarachod hain. I’m from the Australien Government with a message to the world. As cities bake, fires rage, reefs die, jet streams weaken, and 6-Ligma events cause climate scientists to shit their dacks, many are wondering if we’ve finally broken our favourite […]

Map of ensemble mean trends in ocean temperature and ice-shelf basal melting in the West Antarctic Ice Sheet (WAIS) for the Paris 2°C scenario. Temperature is averaged over the depth range 200–700 m. Trends are calculated at each point using annually averaged fields from 2006–2100. White regions indicate no significant trend. The Amundsen Sea region visualized here (latitude–longitude projection) is outlined in red in the inset map of Antarctica (polar stereographic projection). The black dashed line shows the 1,750 m depth contour of the continental shelf break and the blue dashed line outlines the continental shelf region used for analysis. Labels denote ice shelves (G, Getz; D, Dotson; Cr, Crosson; T, Thwaites; P, Pine Island; Co, Cosgrove; A, Abbot). Graphic: Naughten, et al., 2023 / Nature

The climate contradiction that will sink us – “We already have a refugee crisis; I shudder to think what would happen if everyone living within two meters of sea level would be displaced.”

By Zoë Schlanger 10 November 2023 (The Atlantic) – You’d be forgiven for thinking that the fight against climate change is finally going well. The clean-energy revolution is well under way and exceeding expectations. Solar is set to become the cheapest form of energy in most places by 2030, and the remarkable efficiency of heat pumps is driving their own uptake […]

Primary energy global consumption (left) and share of global primary energy by source (right), 2000-2022. Primary energy demand growth slowed in 2022, increasing by 1.1 percent, compared to 5.5 percent in 2021, and taking it to around 3 percent above the 2019 pre-COVID level. Consumption increased in all regions apart from Europe (-3.8 percent) and CIS (-5.8 percent). Renewables’ (excluding hydro) share of primary energy consumption reached 7.5 percent, an increase of nearly 1 percent over the previous year. Fossil fuel consumption as a percentage of primary energy remained steady at 82 percent. Graphic: Energy Institute

World energy system struggled in face of geopolitical and environmental crises in 2022 – Coal production reached record high – CO2 emissions reached record level – “We are still heading in the opposite direction to that required by the Paris Agreement”

26 June 2023 (EI) – The Energy Institute (EI) and partners KPMG and Kearney today released the 72nd annual edition of the Statistical Review of World Energy, presenting for the first time full global energy data for 2022. Five key themes emerge from the data EI President Juliet Davenport OBE HonFEI said: “The EI Statistical Review […]

Shrinking Arctic glaciers are unearthing a new source of methane – “The amount of methane leaking from the springs we measured will likely be dwarfed by the total volume of trapped gas lying below these glaciers, waiting to escape”

By Catherine Martin-Jones 6 July 2023 (University of Cambridge) – As the Arctic warms, shrinking glaciers are exposing bubbling groundwater springs which could provide an underestimated source of the potent greenhouse gas methane, finds new research published today in Nature Geoscience. The study, led by researchers from the University of Cambridge and the University Centre in Svalbard, […]

Texas power struggle: How the top wind power state in the U.S. turned against renewable energy – State lawmakers push bills to support fossil fuel-burning power plants and restrict renewable energy development – “Right now, the wind blows strongly against renewables, and that’s where we are”

By Emily Foxhall, Kai Elwood-dieu, and Zach Despart 25 May 2023 (Texas Tribune) – State Rep. Jared Patterson disagreed with his Republican colleague that Texas should keep supporting the booming renewable energy industry here. Rep. John Smithee was arguing on the House floor in early May that certain solar and wind farms should be eligible […]

Solar power bails out Texas grid during major heat wave – “This is what’s happening with 1 degree Celsius of global average warming. And we’re on track for 3 degrees.”

30 June 2023 (Reuters) – The Texas power grid comfortably met record demand during this week’s heat wave with abundant power supply from wind and solar plants, data from the grid operator showed. The Texas grid is a focus in the United States whenever it is tested by extreme weather after a catastrophic failure in […]

On 27 June 2023, Texas once again braced for a record spike in electricity demand as 110F heat spurred air-conditioning usage. An early heat wave gripped the second most-populous US state, buckling highways, stressing oil refineries and pushing up natural gas prices. At least two deaths were attributed to the searing temperatures and it was only expected to get hotter as the week wears on. It was not a new problem for Texas: The Lone Star State broke power-demand records 11 times in the summer of 2022. Graphic: Bloomberg

Texas power demand again forecast to peak amid Summer 2023 heat wave – “Texas is running about 2 degrees Fahrenheit warmer than it did during the 20th century”

26 June 2023 (Reuters) – Texas’ power grid operator on Monday again projected electricity use would break records this week as homes and business cranked up air conditioning amid soaring temperatures. The Electric Reliability Council of Texas (ERCOT), which operates the grid for more than 26 million customers representing about 90% of the state’s power […]
