Massive lightning storms resulted from the increased temperatures of the day.

The drastic changes to the atmosphere after G-Day led to the rapid increase of global warming and the concurrent onset of frequent thunderstorms.  

Storms often banded together to form squall lines, visible as clouds before a storm and bringing gale force winds which often proved just as devastating as the storm itself.

The drastic increase in ambient electrical activity sparked the imagination of the scientists of the day. They theorized the construction of a "Promethean Machine," able to tap into the supercharged atmosphere to harness the power of the storms.  Liz Butler was the first to construct such a machine, which she successfully tested in “The Promethean Engine.”  

In addition to the thunderstorms there occasionally came a beast hardly discussed for fear that mere mention might summon it: the thermal storm.  These waves of heat could reach such intensity that they would “burn the skin right off your bones.”

During the 2050s, the storms unbelievably became even more severe and many were afflicted with a new condition sometimes called storm-sickness. As storm-sickness disrupted communities with unpredictable violence and strife, scientists with their eyes on the skies feared that things would only get worse before they got better.
