Space weather is a ubiquitous, but little known, natural hazard. Though not as tangible as a volcanic eruption, storm or tsunami wave, space weather has the potenital to cause huge economic losses across the globe. In Europe alone, the interaction of solar wind with our planet’s magnetosphere, ionosphere and thermosphere, could lead to disrutions to space-based telecommunications, broadcasti ...[Read More]

Many of the issues that society currently faces are complex and research on just one angle or area does not provide sufficient information to address the problem. These challenges are compounded when more than one region (or even the entire planet) is impacted. Many of the decisions and legislations passed by governments today will go on to impact how these issues either develop or are resolved ye ...[Read More]

Collapsing dams are a staple of disaster films, but the form that these take in natural systems is also surprisingly varied. Streams and rivers can be blocked by a range of rapid and gradual inputs. One of the lesser-known causes of stream blockage is through the accumulation of large woody debris – tree trunks and large branches – to form a log jam. The impact of these jams on river geomorphology ...[Read More]
