KGW first reported last week the Mauna Loa Observatory on the big island of Hawaii measured the highest level of carbon dioxide on record, back on May 9th.  The measurement surpassed 400 parts per million for the first time since records began back in 1958.  The Mauna Loa observatory has the oldest continuous CO2 record in the world.  Scientists have logged estimates or taken isolated readings by other means dating back 1000s of years.  In fact the rate of increase over the past 100 years is said to be more than 100 times faster than the increase that occurred when the last ice age ended.

Carbon dioxide pumped into the atmosphere by fossil fuel burning and other human activities is the most significant greenhouse gas contributing to global warming or climate change - according to NOAA.  To read the entire article:  researchmatters.noaa.gov/news/Pages/CarbonDioxideatMaunaLoareaches400ppm.aspx
