yup...the rate of increase in atmospheric CO2 during the last 100 years appears to be unprecedented in earth history

Here are some CL images of zircons from the Fish Canyon Tuff from SW Colorado (Schmitz and Bowring 2001). Tuff, of course, being my second favorite rock after granite.

It amazes me how many geoscientific applications there are for zircons. The field would be hurting if they didn't exist!
