CO2,
approx 5 x 8 x 30" Embroidery on silk 800,000 years of CO2 in Earth's atmosphere is embroidered on silk and emerges from an oil can. Emissions of human-caused (anthropogenic) greenhouse gases come primarily from burning fossil fuels: coal, hydrocarbon gas liquids, natural gas and petroleum. Scientists measure the amount of greenhouse gases in the atmosphere using satellites and other instruments, collecting samples of air from specific places. The levels of greenhouse gases that existed in the past are found in ancient air bubbles trapped deep in the ice of Greenland and Antarctica. For more info about CO2, look at NASA and CO2Earth. Other oil can graphs are here. CO2 started out in a 9x 9x3" wooden box for a Textile Study Group of NY show. |
