You know, this guy is onto something. This is a logical conclusion of the Al Gore version of Global Warming. Clearly life is a recent occurrence, so maybe the Creationists and/or Intelligent Design people are onto something. Either there was a creation event, after CO2 dropped to “reasonable” levels or life evolves much faster than we previously believed.
From Real Science:
CO2 levels were 10-20X higher for most of the last 600 million years.
Based on the expert testimony of our top climate
morons scientists, we can be certain that all life forms were destroyed as quickly as they were created – because the weather was so extreme that no life could possibly survive. Sea levels must have been hundreds or thousands of feet higher than they are now, and hurricanes and tornadoes must have roared continuously across a drought and flood covered hot/cold landscape.

There was no oxygen.
Oxygen makes up 21% of the Earth’s atmosphere, and we need it to breathe. But early organisms would have found this environment toxic. Ancient bacteria evolved protective enzymes that prevented oxygen from damaging their DNA, but what evolutionary incentive did they have to do this? Researchers have discovered that ultraviolet light hitting the surface of glacial ice can release molecular oxygen. Bacteria colonies living near this ice would have needed to evolve this protective defense. They were then well equipped to handle the growth of atmospheric oxygen produced by other bacteria that would normally be toxic.
Here’s the whole thing: How Did Early Bacteria Survive Poisonous Oxygen?
I’ve made jokes about the news reports in The Bacterial Times regarding the toxic Oxygen that was appearing in the atmosphere. No doubt the UBN (United Bacterial Nations) was discussing ways to reduce their oxygen footprint…
Early bacterium discovers that its clone is an O2 denier…
