Statistical Insignificance?

I seem to remember from statistics class that anything less than 95 percent probability is junk science. This is an editorial from the most recent issue of GEO, a Norwegian magazine about earth sciences

it is useful to remember that the IPCC concludes that there is only a 90% chance of a connection between global warming and the burning of fossil fuels. In other words, there is a 10% chance – which I consider significant – that there is no connection between the two.

In honor of the 33rd International Geological Congress being held in Oslo this summer, GEO’ 04/08 issue is published in English, so the editorial is legible for people other than the maybe 5 million that speak Norwegian.
