I just did a Google search on HAARP. I see the date "2020" appears to have some significance in that context as well:

"In 1994 the Air Force revealed its Spacecast 2020 master plan which includes weather control. Scientists have experimented with weather control since the 1940's, but Spacecast 2020 noted that "using environmental modification techniques to destroy, damage or injure another state are prohibited." Having said that, the Air Force claimed that advances in technology "compels a reexamination of this sensitive and potentially risky topic.""

And this page has some background information from the perspective of concerned citizens of Alaska ("a coalition of both conservative and liberal organizations") on the subject of HAARP
