What caused carbon dioxide levels to fall?
What caused carbon dioxide levels to fall? Formation of sedimentary rocks As the oceans formed, carbon dioxide dissolved to form soluble carbonate compounds so its amount in the atmosphere decreased. What problems do CO2 emissions cause? They cause climate change by trapping heat, and they also contribute to respiratory disease from smog and air pollution. Extreme weather, food supply disruptions, and increased wildfires are other effects of climate change caused by greenhouse gases. What will happen if CO2 increases? Rising carbon dioxide concentrations will increase plant growth. Rising carbon dioxide concentrations will decrease leaf stomatal conductance to water vapor. This...
