Barriers to Steel Decarbonization
Main identified barriers to steel decarbonization Carbon dioxide (CO2) emissions are a leading contributor to global climate change, necessitating urgent mitigation strategies. While various metrics—such as total national emissions, per‐capita output, and historical contributions—define responsibility, determining accountability remains complex ...

The impulsivity of solar flares: concepts and applications [PDF]
During the impulsive phase of solar flares a distribution of nonthermal electrons propagates from the site of energy release towards the lower layers of the solar atmosphere.

Abstract The F10.7 solar radio flux density, or F10.7, is a disk‐integrated measure of the Sun's total emission at 10.7 cm (2.8 GHz) and is a widely‐used proxy of solar activity. F10.7 emissions primarily originate from the Sun's upper chromosphere and lower corona. High‐frequency, transient “radio bursts” can dramatically increase the magnitude of F10.

The driving mechanism of solar flares and coronal mass ejections is a topic of ongoing debate, apart from the consensus that magnetic reconnection plays a key role during the impulsive process.

Cosmic Ray Anisotropy Generated by the June 22nd 2015 Interplanetary Events
Abstract On 22 June 2015, the near Earth interplanetary space was perturbed by a series of high‐speed streamers and interplanetary coronal mass ejections associated with an active region and two low‐latitude coronal holes. The interaction of these disturbances gave rise to the complex solar wind structure observed at 1 au.

Can Solar Cyclic Variability Mimic Extreme Solar Particle (Miyake) Events in Radiocarbon?
Abstract Rapid, strong enhancements in Δ14 ${{\Delta }}^{14}$C in the Earth's atmosphere, known as Miyake events, rarely occurred over the past millennia, pointing to major radiation storms affecting Earth. They are produced by extreme solar particle events (ESPEs) and are separated by an order‐of‐magnitude gap in the strength from directly observed ...

Uranus's Highly Nonaxisymmetric Magnetopause and Its Impact on Magnetic Reconnection
Abstract Mass and energy fluxes from the solar wind can access a planet's magnetosphere through dayside magnetic reconnection. The plasma and magnetic field conditions on either side of the magnetopause determine whether reconnection is suppressed. However, magnetosheath conditions are sensitive to the shape of the magnetopause, and deviations from ...
