Chronicle with CCS criticism, replies

My chronicle "Om 10.000 år, hvem tar regningen for vår karbon­fangst og -lagring?" was published in the daily newspaper Stavanger Aftenblad November 16th. A reply, "Alt tilsier at lagring er trygt over et tidsrom på 10.000 år" by professors Helge Hellevang and Snorre Olaussen, was published November 25, to which I replied with "Om 100 år er alt glemt?", published December 2nd.
