American Supercritical, a startup founded by Simon Shuham and others, emerged from stealth with $8 million in funding for technology that uses supercritical carbon dioxide to boost the efficiency of gas turbines powering data centers. The company plans to retrofit simple-cycle turbines—common at data centers but far less efficient than combined-cycle plants—so they generate more electricity without increasing fuel use, though the turbines will still emit carbon pollution from burning gas.

A new analysis by Suhrhoff et al. published in Nature examined water chemistry across the Mississippi River basin and found that agricultural liming, long classified by the IPCC as a greenhouse-gas source, has actually removed more CO2 from the atmosphere than it released. US farmers apply over 30 million tonnes of lime annually to manage soil pH, and the reaction was previously assumed to emit CO2 directly.

A new UN Environment Programme report concedes that global warming will surpass the 1.5-degree Celsius threshold set by the Paris climate accord within the next few years, driven by continued burning of coal, oil and gas. Current temperatures already sit around 1.4°C above pre-industrial levels based on 20-year averages, and scientists say there is no longer a realistic path to staying under the limit.

The UN Environment Program's new Limiting Overshoot report acknowledges that global temperatures will rise past the Paris Agreement's 1.5°C threshold, and instead focuses on how to minimize the severity and duration of that overshoot. The plan calls for nations to simultaneously cut greenhouse gas emissions to net-zero and deploy large-scale carbon dioxide removal, treating the latter as a supplement rather than a substitute for emissions cuts.

A survey of recent research consolidates evidence on how electrical double layers at charged interfaces behave when driven away from equilibrium, drawing on decades of double-layer theory alongside newer studies of cation effects in CO2 reduction and fuel-cell electrocatalysis. The compiled literature spans classic Gouy-Chapman-Stern-Grahame models through modern spectroscopic and computational probes of interfacial water and ion behavior under applied current.
