United States: 4,595,406.7(1970),4,984,066.7(1990),5,888,498.7(2005), 4,959,631.9(2017),4,853,780.2(2022) Fossil CO2 emissions (ktCO2/year) Millions of tons is a lot, but when the overall Fossil CO2 emissions are in trillions then it isn't really where we need to focus. I can't see how they're justified in saying it is a significant contributor. There are probably plenty of reasons aside from CO2 to maintain the lake.
