Each point on the line represents the total amount of CO2 released into the atmosphere during that particular year, providing a visual representation of how human activities have impacted our planet's climate system. Description of the Chart Starting from the left, we observe that in 1990, global...

Mountain uplift and erosion have regulated the balance of carbon between Earth’s interior and atmosphere, where prior focus has been placed on the role of silicate mineral weathering in CO2drawdown and its contribution to the stability of Earth’s climate in a habitable state1,2,3,4,5. Howev...
A demand of empty calories found in products like refined cereals, refined sugars, alcohol, and oils was another of the global changes. Finally, the total per capita caloric demand increased as well [2]. New food habits and dietary changes have affected the amount of CO2 in the atmosphere,...
“Considering the fact that present human activities, primarily through fossil fuel burning, are releasing vast quantities of carbon into the Earth’s atmosphere and oceans at a rate never before seen in the geological past, it appears that the world is racing toward another major mass extinction...
By linking different stages of industrialization and income level with the complex structure of the environment, the EKC hypothesis unveils the concentration of toxic substances in the atmosphere of a nation as it prospers economically. Due to its apparent importance, the EKC hypothesis has been ...
in atmosphericCO2level and then a long slow decline once equilibrium between theatmosphereand oceans was reached. This matches what is shown in the chart. Thus, while it would take tens of thousands of years to get back down to the historical level of ~280ppmfrom where we are now there ...
Although our model included the most significant carbon reservoirs, it omitted other real-world elements such as marine biota interaction within the surface ocean, sediment deposit within the deep ocean and weathering within the atmosphere. Our model will not have perfect parity with historical data;...
In 2017, the concentrations of the three major GHGs, namely carbon dioxide, methane, and nitrous oxide in the atmosphere were 405.5 ppm, 1859 ppb, and 329.9 ppb, respectively2, which were approximately 46%, 157%, and 22% higher, respectively, than the levels before widespread industrialization...
Over the past decade, concern over potential global warming has focused attention on the emission of greenhouse gases into the atmosphere, and there is an ... TM Selden,Douglas and Holtz-Eakin - 《Nber Working Papers》 被引量: 1734发表: 1995年 Determinants of CO2 emissions in a small open...
