Based on ice core data and recent direct measurements, this graph provides conclusive evidence that atmospheric CO2 has increased well above the expected natural variation since the Industrial Revolution. (Source: NOAA)
Most scientists now agree that the increase in atmospheric CO2 and the associated warming in the last 100 years is due to human activities.
Focus should now be on the affects this change will have on our planet and us! How can we keep the climate from changing past “dangerous levels”? How can we minimise the impact associated with a changing climate?
More dedicated research is needed before we can properly address these questions.
