There is no better eye catcher in your family if you are wearing a Keeling Curve T-shirt, which is printed in San Francisco, CA with upcycled CO2 emissions. Check out Carbon Upcycling Technologies for more.

The design on this t-shirt is based on an abstracted and repeated image of the Keeling Curve, a graph depicting the changes in atmospheric carbon dioxide concentrations first recorded in 1958 by Dr. Charles David Keeling at the Mauna Loa Observatory in Hawaii. It has been printed with ink made from CO2-enriched graphitic nanoplatelets mixed into a transparent ink base. The t-shirt is a white unisex poly-cotton crew neck shirt.
