The Nordic Bronze Age...

The Nordic Bronze Age from 1700 BC - 500 BC was a relatively warm period with good farming and a dense population. People had more energy and time to spend on things like art and other things related to their culture.

The Battle against Rome...

This is the English version of 'Kampf um Germanien - Die Varusschlacht' from 2009. A documentary made by Germany's ZDF (TV station) about Armenius or Hermann who led the Germanic tribes in the battle against Roman occupation of the land between the Rhine and Elbe rivers - the northern front of the Roman Empire.

The battle of the Teutoburg Forest in 9 AD ended the Roman advance north. This is a two episode series - each episode is about 45 minutes long.

Magnetic Storm - Earth's Invisible Shield...

A NOVA (PBS) film about magnetic reversal (when the magnetic north and south shift places)...

Like the plot of a sci-fi B movie, something weird is happening deep underground where the constant spin of Earth's liquid metallic core generates an invisible magnetic force field that shields our planet from harmful radiation in space. Gradually, the field is growing weaker. Could we be heading for a demagnetized doomsday that will leave us defenseless against the lethal effects of solar wind and cosmic rays? "Magnetic Storm" looks into our potentially unsettling magnetic future.

HAARP - Controlling the weather...

The High Frequency Active Auroral Research Program (HAARP) is an ionospheric research program jointly funded by the U.S. Air Force, the U.S. Navy, the University of Alaska, and the Defense Advanced Research Projects Agency (DARPA).

Built by BAE Advanced Technologies (BAEAT), its purpose is to analyze the ionosphere and investigate the potential for developing ionospheric enhancement technology for radio communications and surveillance. The HAARP program operates a major sub-arctic facility, named the HAARP Research Station, on an Air Force–owned site near Gakona, Alaska.

The most prominent instrument at the HAARP Station is the Ionospheric Research Instrument (IRI), a high-power radio frequency transmitter facility operating in the high frequency (HF) band. The IRI is used to temporarily excite a limited area of the Ionosphere. Other instruments, such as a VHF and a UHF radar, a fluxgate magnetometer, a digisonde, and an induction magnetometer, are used to study the physical processes that occur in the excited region.

Work on the HAARP Station began in 1993. The current working IRI was completed in 2007, and its prime contractor was BAE Systems Advanced Technologies. As of 2008, HAARP had incurred around $250 million in tax-funded construction and operating costs.

Global dimming...

Global dimming is the gradual reduction in the amount of global direct irradiance at the Earth's surface that was observed for several decades after the start of systematic measurements in the 1950s. The effect varies by location, but worldwide it has been estimated to be of the order of a 4% reduction over the three decades from 1960–1990. However, after discounting an anomaly caused by the eruption of Mount Pinatubo in 1991, a very slight reversal in the overall trend has been observed.

Global dimming is thought to have been caused by an increase in particulates such as sulfate aerosols in the atmosphere due to human action.

It has interfered with the hydrological cycle by reducing evaporation and may have reduced rainfall in some areas. Global dimming also creates a cooling effect that may have partially masked the effect of greenhouse gases on global warming.

Deliberate manipulation of this dimming effect is being considered as a geoengineering technique to reduce the impact of global warming.
