Saving Earth – time for a new cooperative framework
.... Although such a major event is predicted to occur only every 150 years or so, this is not to suggest that destructive coronal mass ejections are rare events. A geomagnetic storm in March 1989, the so-called ‘Montreal event’, took out power between...

Growing space agency dilemma
... threats we need to start taking quite seriously. In a very real sense we are dealing with cosmic fire. A spectacular coronal mass ejection (CME) erupts from the Sun’s solar corona releasing plasma and magnetic field. The National Intelligence...

Big science from small spacecraft
... The Sun is a massive, roiling, dynamic object at the centre of our solar system. Energetic solar flares, known as Coronal Mass Ejections, shoot out beams of high-energy electrons that can go out far into interplanetary space. As they interact...

In thrall to a star: understanding the Sun will help us understand our own climate and environment
... Earth’s space environment. Of particular concern are the transient sudden-onset events, the solar flares and coronal mass ejections, which release huge amounts of energy in a short time, imparting much of this to the Earth’s magnetic environment and...

Humanity is moving towards a new reality
... space hazards can threaten global prosperity. A study by Lloyd’s of London, for example, has suggested that a massive coronal mass ejection (CME) from the Sun could result in a two trillion dollar hit to the North American electrical power...

URBOCOP: saving planet Earth
.... Among these, I categorise the following seven as the most dangerous threats: Solar storms and flares, known as coronal mass ejections. Changes in Earth’s magnetosphere which result in the destruction of the protective shield that could deflect...
