Land Use Change over the years

According to the Woods Hole Research Center, about 100 Pg (one petagram = 1 billion metric tons) of carbon (not carbon dioxide, petagram 1 billion metric tons) of carbon (not carbon dioxide, which is much heavier) were released into the atmosphere from changes in land use world‐wide between 1860 and 1990.

US Emissions

A regional measurement‐based model for CO2 emissions in the US

The map shows annual emissions in 2002 (in kilotons of carbon, with 1 kiloton equivalent to about two million pounds) from urban centers (larger red patches), widely scattered point sources like remote power stations or smelters (small red
