SPLATS about catastrophes
The principles of catastrophes
- Catastrophism was an attempt to give a place to Noah's flood in the shaping of a world believed to be just 6000 years old, but the model is badly flawed.
- Occasionally, catastrophic events do shape the Earth, and these include asteroid strikes, volcanic eruptions, polar reversals and sudden changes in climate.
- In 1980, Luis and Walter Alvarez, Frank Asaro, and Helen Michel proposed that a giant comet or asteroid may have struck the Earth about 65 million years ago.
- This comet, they argued, caused massive extinctions and enriched the iridium in the K-T (Cretaceous-Tertiary) layer, and in passing, killing all the dinosaurs.
- In 1986, a hole in the ozone layer was first reported. In Europe and America, it was dismissed as 'only a threat to a few penguins who sunbake'.
