Doomsday Clock

[wee_blondie]

Can anybody tell me what this is and how they calculate what time to set it to? How long do the minutes represent??

This week its been quite high profile in the news as it was set forward (i think to 11:57) due to the war in the middle east and CO2 emissions. Just wondering how significant this is?
