Add CommentFrom what I gather, the amount of CO2 in the atmosphere has risen, during the past couple of hundred years, or shall we say since the beginning of the Industrial Revolution, from about 1/4th of 1/10th of 1 percent to the present levels of about 2/5ths of 1/10th of 1 percent, that is from 250ppm to 400ppm, which is an increase of 150ppm or 0.00015%.
Reply | Report Abuse | Link to thisIf we assume this effect, of increasing levels ofCO2 reducing the resistance to fracture in pure ice, is a linear effect, then on the basis that a 2% increase causes a 38% drop in the resistance to fracture, a 0.00015% increase in CO2 should result in a (38 x 0.00015/2) percentage drop in cracking resistance, or a resistance to fracture which is lower by 0.00285% as a result of our irresponsible emissions of CO2.
Maybe I've got my maths wrong. If so, please correct me.
You forgot the other equation: 0.00285% * ("Co2 is bad paper" constant) = lots of funding. That might throw some light on this mankind's next amazing scientific achievement.

Now let us see if the word damage occurs in the scientific literature.

Why yes it does. Fancy that! And look here the disappearance of glacier results in local communities losing access to traditional water sources:

But I am guessing that you think local communities losing water resources is not "damage".
