“A fireball powerful as hundreds of Hiroshima atomic blasts scorched through the upper atmosphere...”
OK... This was in 1908. How come the rest of the planet didn’t suffer? Why didn’t we as a species go extinct? Why weren’t our skies darkened for months, killing the ozone layer and bringing on global warming?
Yet, this is the type of scenario they teach us is what killed off the dinosaurs...
maybe the one in the Yucitan was the size of...Yucitan?
The size of he Tungusku boloid was probably about 40 meters in diameter. The size of the Yucatan boloid was probably about 10 kilometers. “Since the 1908 comet was probably traveling in a direction opposite to that of earth...would give a speed of 60 kilometers per second.” The explosion had about the force of 700 Hiroshima bombs. “Vast amounts of fire debris arrived in California some two weeks later, noticeably depressing the transparency of the atmosphere over the Golden State.” In 1978 a Czech astronomer noted that comet Encke had changed its orbit in 1908 which could have been induced by losing a Tunguska object sized fragment. Microtectite spherules found at the Tunguska site have an iridium concentration as high as 56,900 parts per billion which is similar in content to an iron meteorite.

I highly recommend this book to anyone interested in extraterrestrial extinction events even though it was written just before the discovery of the 100 mile wide Yucatan crater site. The book covers the early development of earth sciences, and the dispute between uniformitarians and catastrophists. It does a very good job of showing the checks and balances of the scientific process which finally promoted the search for the missing crater. This discovery was a big boon for modern catastrophists.
I hope it is clear that the reason we did not go extinct is that there is a big difference between the blow from a 125 foot object, and one 7 miles in diameter.
