Recently, 86 evangelical leaders signed an initiative urging the adoption of legislation to reduce carbon dioxide emissions (see Evangelical Leaders Join Global Warming Initiative).
As can be seen, only about half of carbon emissions can be found in the atmosphere. Originally, researchers had thought that all the extra carbon dissolved in the oceans.
Some of these changes include clearing the land for agriculture and burning carbon sources for heat.
As the human population began to increase rapidly, these "insignificant" changes began to have global impact. century began humanity's rapid addition of carbon into the atmosphere.
The extensive use of petroleum and natural gas after World War II has rapidly increased the amount of these carbon emissions within the last 50 years.
These data strongly suggest that the rapid increase of CO than is showing up in the atmosphere (Figure 3).
