Explosions in the sky February 16, 2013Posted by WorldbyStorm in Science.
Ironically, or perhaps not, this came out the day before the Russia meteorite came down…
There was this line in it which I think was useful:
(Only a full-scale nuclear war with Russia might approach the damage of a large asteroid, and that’s not what the billions spent on radiation scanners at container ports, and similar measures, are meant to avert.)
And if that intrigues you you may find this of interest….
I’ve got to admit that the footage of the meteor as it descended is fairly chilling to me, particularly in the shots where it is moving in the general direction of the cameras (by the way, for an explanation as to why there was so much excellent footage consider this).
The big problem is that broadly speaking of all the potential extinction level threats we face this is one of the very few we can actually do something about with contemporary, or practically foreseeable, technology. Tellingly it was only in the 1980s that the threat actually was recognised. But to date the response is a patchwork quilt of essentially ad-hoc organisations (and a nod from the US government) with no clear international effort to combine both the surveillance aspect – which remains partial, and the means to fend off such threats – which remains as of now non-existent.
Indeed the situation has hardly moved on since this was written back in the early days of this blog.
Though this from the Guardian was a bit entertaining yesterday.
