|Number One: Possibly an example of it being best to go with one's first instinct. Three concentric circles with a bulls-eye; Target Earth.|
Number Two: Same general theme. I thought the pointyness might suggest, you know, a threat or disaster.
|Number Three: A bit of a different variation; the six circles represent the six electrons in the carbon atom. This at least identifies the culprit.|
In thinking of what a universal greenhouse disaster symbol should be, even without Bruce's references one would first think of the universally-known radiation and biohazard symbols. Those two glyphs have several traits in common: they are symmetrical, they are effective in one color, they are easily reproducible (i.e. with a simple stencil) and are comprised of simple, geometric forms.Neither the radiation hazard nor biohazard glyphs have any real symbolic link to the dangers they warn of. The hardwired fight-or-flight sensation they can produce is the product of their universal, long-term use in the context of, "If you can read this, you're hosed." I hoped to put together a greehnouse glyph with at least some symbolic link to the dangers it warns of.
The greenhouse disaster glyph represents a shrinking Earth in the sense of a reduced area of habitability and carrying capacity. This is represented by the concentric green circles. The white crossbars can be inferred to represent the division and separation of habitable areas and ecosystems or just that this thing the glyph is attached to is/was in the bulls-eye. The white bars also provide anchors for a stencil pattern.
