Carbon Dioxide Has Governed Earth's Climate Change for Nearly 500 Million Years, New Research Unveils Deep - time Climate Evolution Map
Recently, scientists from the United States have reconstructed the curve of Earth's average temperature changes over the past 485 million years. By integrating 150,000 paleoclimate records with model simulations, they found that extreme warming events on Earth are highly correlated with the increase in CO₂ concentration. This research was published in the journal Science.
Hydrogen Plasma - based Extraction of High - Purity Iron from Red Mud Drives Green Metallurgy
European scientists have developed a new method that uses hydrogen plasma to reduce iron oxide in red mud, capable of producing liquid iron with a purity of over 95% in just a few minutes. This process contains almost no harmful elements and is suitable for steel - making. Meanwhile, it can consume red mud, an industrial solid waste, and is expected to solve the environmental problem of 180 million tons of red mud produced annually.
Emerging Weapons Technologies to Reshape Battlefields Over Next 30 Years
Over the next three decades, several new weapons technologies will emerge on the battlefield. Beyond currently developing non-lethal and energy weapons, multiple nations are pursuing anti-access/area denial (A2AD) systems to block military operations. A2AD technologies include anti-ship ballistic missiles, precision-guided anti-vehicle and anti-personnel weapons, counter-rocket, artillery, and mortar (CRAM) systems, anti-satellite weapons, and electromagnetic pulse (EMP) devices.
