The current concentration of CO2 in the atmosphere is about 415 ppmv. It has been estimated that annual anthropogenic additions to the atmosphere are about 30 gigatonnes (Gt), of which about 15 Gt are removed into oceans and the terrestrial environment. a) Use these values to estimate the yearly net increase in atmospheric carbon dioxide mixing ratio, in ppmv. (note that 1 Gt = 1015g)
The three images below are snapshots of the atmospheric CO2 concentration in May, July, and September of a year. To interpret the CO2 concentration: blue/green/yellow indicates lower to medium CO2 concentrations and red/maroon/pink indicates medium-high to highest CO2 concentrations.

Mercury Emissions by Continent By weight, coal does not contain much mercury, but we burn a lot of it. Several industries besides coal-fired power plants contribute substantially to atmospheric mercury pollution. FIGURE 2.13 shows mercury emissions by industry from different regions of the world in 2010. FIGURE 2.13 Global mercury emissions by sector, 2010. About how many metric tons of mercury were released in total from these regions?
