The average CO2 measured in the atmosphere in Hawaii now stands at over 400 ppm. This is the highest CO2 concentration measured in the atmosphere ever. Compare this with the CO2 measured from bubbles in ice core from Antarctica.
This is CO2 measured from bubbles trapped in ice aged 800,000 yrs in Antarctica. This is an historic event. This level of CO2 has been in our atmosphere for the last 800,000 years. See the Keeling curve: (courtesy of the Scripps Institution of Oceanography)
See below, the CO2 in the atmosphere measured by bubbles in ice core dated back 800,000 yrs. See the current level of CO2 at 400 ppm for 0 years on the time scale.
In the The world's oceans act as a huge buffer, absorbing CO2 from the atmosphere, but it cannot absorb it at the rate it is being produced in the atmosphere. It will continue to rise and if the world continues on its course to increase greenhouse gases into the atmosphere the Earth is headed for a runaway greenhouse effect. This is what is thought to have occurred on Venus. In the graph below, you can see the dramatic rise in CO2 caused by the man-made Industrial Revolution.
However, I believe it will not get this bad. Weather change and droughts will undoubtedly change politicians mind far before this... hopefully.
