author and paleontologist.
he rambled about life on earth and how the fossil record indicated the crater impact. he presented the evidence for this. it ended up being interesting. he talked about the longevity of bacteria. especially green sulfur bacteria. H2S can be given to a mammal and turn it into a reptile. then cool the mammal.
he suggests that humans have a reaction that allows us to produce H2S and survive huge heights of CO2. this very hard to understand and believe.
the earth has never had any ice on it when CO2 has been above 1000ppm. we are now at 380 and rising.
Rare Earth. Whey complex life is uncommon in the universe
