Earth Heat, Salty Seas

The heat beneath: harvesting and recharging Earth subsurface heat, to heat and cool buildings, without heating Earth’s atmosphere. And, the wind blows, the sun shines … rivers flow. Wherever they flow into salty seas, power can be generated – just like that. A special GPM edition about geothermal, geoexchange and salinity gradient energy.



Land & People

Clinging to the walls of a fertile valley beneath the city of Bethlehem, a half dozen kilometers south of Jerusalem, alienated from the holiest of Palestinian towns by walls, barbed wire and a string of mega-colonial settlements, boxed in by settler-only roads and militarized checkpoints, Mazin and Jessie Qumsiyeh and their friends are planting native Palestinian seeds, growing fruits and vegetables, raising chickens, rabbits and fish, and offering up habitat for birds, insects and other wildlife. Rescuing their beloved landscape cruelly scarred by land thieves without true roots.


Tipping Points
