Can Humans Affect our local Space Weather?

Very interesting article on the NASA blog about how human activity can affect Space Weather around our planet. From the article:

“A number of experiments and observations have figured out that, under the right conditions, radio communications signals in the VLF frequency range can in fact affect the properties of the high-energy radiation environment around the Earth,” said Phil Erickson, assistant director at the MIT Haystack Observatory, Westford, Massachusetts.

Another NASA video (screenshot below) explains how “Human Activity Impacted Space Weather“, based on results of experiments from Cold War nuclear tests.
