After studying solar storms in great detail, we have come up with a unanimous response. NO, current technology could not withstand a solar storm similar to that of 1859. All the scientists and experts that we have contacted share this opinion.
Multiple major arguments have led us to this conclusion. Indeed, as explained in the impact tab, a solar storm would have damaging effects on technology. The different components of a solar storm, the solar flare, and the coronal mass ejection may cause malfunctions in the atmosphere (satellites), ionosphere (GPS), and on Earth (electrical grid).
Apart from the direct consequences of a solar storm, it is important to consider the indirect consequences. Indeed, the latter would be important, and in particular for the departments dependent on technologies. We can raise for example the banking and financial sector, the air transport as well as of numerous domains. Because of these failures, the world economy would be frozen for a few days, maybe even a few weeks: a total blackout is highly conceivable.
These impacts may take a considerable scale: in one of its reports, the OECD evaluate the overall cost of a Carrington-type event today in trillions of euros.
However, one must not liken this negative answer to an apocalyptic scenario. Humanity would only undergo very few consequences, as the magnetosphere protects us.
For a few years, several anticipation and protection measures have been set up by SWPC (Space Weather Prediction Centre), FEMA (Federal Emergency Management Agency), etc. Given the human and financial resources currently in place, there is no doubt these measures will improve over time, which would enable us to efficiently prepare our planet against such an important solar storm. It should also be noted that all countries do not have the same measures, some like the US, Canada and UK have much more advanced surveillance systems.
