Historic Day for CO2 Concentration in Atmosphere

rajendrashende‘s insight:

9 May 2013. The average daily temperature measured at weather station in Hawai touched 400 ppm. That level was never reached  for last 3 million years and defintely not for the the time since the reading started in Hawai. This is not a wake up call. It is wake up shock.
