solar flares and the electric grid

I think the scientists interpret it in the worst case scenario intentionally, so we're ready for whatever might happen.

Yeah right. That is why the reality of climate change effects usually are happening above the projected impacts coming out of climate science. (e.g.: http://www.sciencedaily.com/releases...0818132221.htm)
But yes of course - scientists will usually tell what will happen if nothing is done - because obviously the goal is to make people do something. The reason why the predictions of biologists in the 1980ies that the forests of Europe will die from acid rain did not come true was that people acted upon that and stopped making acid rain. With climate change, this is not happening. I dont know if upon these predictions about the soalr flares people will come and create safeguards for their technology that could protect it - maybe but maybe not.
