Does one not think for a moment that vehicle emissions aren't getting trapped, warming the atmosphere? I do. Did the ice packs melt many years ago like they'reare doing now? I've never heard/read anything about it if they did.
Actually, there was something on the Science Channel a few weeks ago that showed we are in the 4th or 5th cycle like this. Previous ones may have been caused by volcanoes, meteors,fires,or God (show didn't mention The Lord), but it has happened before and will happen again.
