IMHO, every scientific idea has an impact on society. The
question then becomes - what constitutes 'far reaching'.
One could say that global warming has not had a far reaching
effect since society has not changed what they are
doing to mitigate its effects. Or you can say that it has
already had a far reaching effect given the damage being
caused by fires, tornados, rain, drought, etc. being effected by
global climate change.
