There is an easier way of predicting long term climate change and it has nothing to do with carbon dioxide or man made “pollution” – it relies on observing solar activity such as sun spots etc to determine whether it is going to get hotter or cooler on the cosmic spec of dust we call earth.

The use of passive solar energy in housing involves the placement of the building for optimum benefit, the building design and position of suitable building components to make full use of sunlight for day lighting, passive heating, and/or passive cooling. Apart from saving energy, the primary benefit of a passive solar home is the improved comfort of its occupants.
