Carbon dioxide (CO2) is a greenhouse gas that has a significant impact on climate. Human activities, such as the combustion of fossil fuels and deforestation, have inadvertently put more CO2 into the atmosphere than was present before these activities became widespread. Because matter cannot be destroyed, it must be cycled out of the atmosphere and it was long thought that the oceans and vegetation would have the capacity to do so. Regular measurements of atmospheric CO2 levels have been taken at Mauna Loa, Hawaii since the end of the 1950’s, providing a substantial amount of historical data with which we can track the concentration of CO2 in the atmosphere over time.
Carbon dioxide concentrations in the atmosphere are measured in parts per million (ppm). To see how these concentrations have been rising or falling in recent times, create a graph showing the monthly average of carbon dioxide concentration in parts per million (ppm) between January of 2012 and January of 2014. Using the drop down menus, you can select the time frame for the data set you would like to display.gnMmGMlTiNF5yvi0QuUUDNzsYwn6OUjI33SGyJdK9jm/OtJgGjoqmB9VSr2lroj2C0o2bK7Wr8dKUQQErlo4dADgPgXApir/TuhcKwy2JM93te5EEwRt7I/u1F9K528n4hegZRabdMOFybovfWjiF8+OoaZYt2Bbp+E8CbM/lv+nMTswRvYJj4pV1XQeEYqTmxZFEkffg4GbV/bBxrZIoinI/LAftcWfNbuaUYhsrMBjxWGz
Now create a graph showing the monthly average of carbon dioxide in parts per million (ppm) between January of 1970 and January of 1972.bTnCCu5ITeawn4OnSviXhZfRnaPO4OSJZk+H7RMUZlkDyGnkhZvmwXC2FsjEyI0h6tGwiE9TsWeG+dANtQUegam5pYIM4TedaLFshxjyWTiKZPPI5UwTKQG3xf79+ljrqW3OJLXQcHfQmoUddPMak1xkHtGb6NVLfHcBIgB+zFmUstqWlEfvN5MmYNeMFa1sduFghJlaNUBasAmwncE9Xm/g5FHdetis8nc6PMMoantDOK5Xo9LGIk3kWIuyTZGKl+7ceqhFKyZ3O2AlIfjfJ+lacnNN6iMuD5hFF4G5iAlaX4gaP9epLw==
