Resilience and vulnerability to solar events
How to Watch the Sun (and why we do it)
Well researched and visually fascinating, this documentary takes you through the satellite tracking data which any of us can look at, with explanations about what
the data represent, and how a 'Carrington event', (or very powerful impact of charged material from the sun), could completely alter things on earth. Last time it happened in the late 19th century, telegraph offices burst into flames. A few years ago Sweden had major problems from power disruption caused by a solar event. If it happens again on a large scale everything that depends on electricity could be affected, maybe for a long time. Power supply companies are trying to build as much protection as possible into systems, recognising this vulnerability. Emergency services worldwide are investing in equipment in preparation for just such an event.
In the past, we know that these events happened but they did not pose such a threat to infrastructure in a world which did not depend so totally on electricity. The earth's magnetic fields were also stronger than they are now (it is scientifically proven that earth's defences are fading). This overview will make you think carefully about how vulnerable we are and what we can do to build more resilience into our designs.
