Russian Meteor, is neo-catastrophism coming of age?

9 March 2013

You'd think so when you read the piece at http://phys.org/print281961666.html … as there are a lot of people out there that have a career revolving around looking out for space rocks. Astronomers are keen on impactors but many geologists are luke-warm. Some of them don't even want to face the reality of 140 + known craters. Hopefully, the next generation of geologists will have a more grown-up attitude towards ne-catastrophism and realise punctuated uniformitarianism might just go hand in hand with punctuated biology (evolutionary changes brought about by neo-catastrophic events). There is something of this flavour in this piece, quoting Glimsdal et al (2007) on impacts and tsunamis, Mark Boslough (on Tunguska), Neil de Grasse Tyson (on the Russian meteor), the Shiva hypothesis, the Oort Cloud (Raup), and a team that in 2007 (unnamed) came up with the idea that the asteroid that brought the Dinosaur era to an end had entered into an Earth crossing orbit via resonances and asteroid 298 Baptistina is a fragment of it, still out there.
