Problem: The primary source of rain in the Sahara is the equatorial low a continuous belt of low-pressure systems near the equator which bring the brief, short and irregular rainy season to the Sahel and the southern Sahara. The Sahara doesn't lack precipitation because of a lack of moisture, but due to the lack of a precipitation-generating mechanism. Rainfall in this giant desert has to overcome the physical and atmospheric barriers that normally prevent the production of precipitation. The harsh climate of the Sahara is characterized by extremely low, unreliable, highly erratic rainfall; extremely high sunshine duration values; high temperatures year-round; negligible rates of relative humidity, a significant diurnal temperature variation and extremely high levels of potential evaporation which are the highest recorded worldwide.

Problem: Greece was eventually occupied by the Nazis who proceeded to administer Athens and Thessaloniki, while other regions of the country were given to Nazi Germany's partners, Fascist Italy and Bulgaria. The occupation brought about terrible hardships for the Greek civilian population. Over 100,000 civilians died of starvation during the winter of 19411942, tens of thousands more died because of reprisals by Nazis and collaborators, the country's economy was ruined and the great majority of Greek Jews were deported and murdered in Nazi concentration camps. The Greek Resistance, one of the most effective resistance movements in Europe fought vehemently against the Nazis and their collaborators. The German occupiers committed numerous atrocities, mass executions, and wholesale slaughter of civilians and destruction of towns and villages in reprisals. In the course of the concerted anti-guerrilla campaign, hundreds of villages were systematically torched and almost 1,000,000 Greeks left homeless.
