There is a weekly co2, which we have 4 times a month. For the first week of January 2011 we are at 391.65 ppm. January year--start-end 2010 388.02 to 389.58 2009 386.36 to 387.49 2008 384.37 to 386.59 ftp://ftp.cmdl.noaa.gov/ccg/co2/trends/co2_weekly_mlo.txt The new data for the 2nd week should be out within the next few days... This thread is to discuse the data and to watch the co2 rise. Not a thread to be discussing rather it has any effect on climate or historic co2.
