Never explained is why volcanic eruptions suddenly began globally, then quickly and continuously distributed nuclei throughout the atmosphere for up to 40 days. Volcanic eruptions, rather than contributing to the flood, require special conditions that seem to be a consequence of the flood. 13 The Greenhouse Problem. While sunlight can pass through glass into a greenhouse, heat in a greenhouse has more difficulty radiating back out through the glass. This greenhouse effect traps heat inside the greenhouse, raising its temperature.
All canopy theories have a greenhouse problem.
Also, if temperatures under a canopy rose, more water would evaporate from the earth's surface, especially its oceans. More water vapor in the air means a greater greenhouse effect, a warmer atmosphere, and even more evaporation. For example, Venus' atmosphere has experienced a runaway greenhouse effect. Venus is about 700 F hotter than one would otherwise expect for a planet that near the Sun. Because of our atmosphere, earth is about 60 F warmer than it would be if there were no greenhouse effect.
