What happened to the carbon dioxide level in 1950?

Answer 1

In 2000 carbon dioxide emissions were 368 ppm (parts per million). This year (2013) they reached 400 ppm. At the beginning of the Industrial Revolution they had been 280 ppm for thousands of years.

Answer 2

Carbon dioxide levels began to increase in 1950 due to human activities such as the burning of fossil fuels, deforestation, and industrial processes, leading to an overall rise in atmospheric CO2 concentrations. This increase has been linked to climate change and global warming.

Answer 3

The carbon dioxide levels in the atmosphere have increased since 1958. Now there are more than 395 parts per million of carbon dioxide in the atmosphere.

Answer 4

it skyrocketed

from 1850 CO2 levels had risen excessively (which makes sense because the industrial revolution began in the 1850s) then in 1950 the CO2 levels rose even more

Answer 5

In 1990 it was 353 ppm. Today (2012) it is 393 ppm.

Answer 6

Carbon dioxide levels in the atmosphere in 1850 were around 290 ppm (parts per million). Levels now (2013) are approaching 400 ppm.

Answer 7

Levels have risen from 315 ppm (1960) to 392 ppm (in 2012).
