Report on Space Weather impacts to finance published

Publication date:

UCL researchers have been applying their knowledge of “space weather” to help the the finance sector build their resilience to this natural phenomenon. Space weather refers to changes in the near-Earth space that are caused by the Sun. Huge explosions and eruptions in the Sun’s atmosphere reach out and cause changes in the Earth’s magnetic field and atmosphere, and this ultimately has knock-on effects to much of our modern technology, for example electricity distribution, satellite services and communications. A new report led by UCL lays out guidance on how to factor space weather risks into business resiliency planning for the finance sector, and discusses how businesses might be impacted.
