This data set will be updated near the end of each month. This data set will contain the latest CO2 Data readings from the Mauna Loa, Hawaii Observatory. Our Start Point here at 40 North Latitude will be January of 2019. At the bottom of the table there are also 3 rows which cite the starting point in March of 1958 in which the Scripps Institute began collecting data. May of 1974 where NOAA began collecting CO2 data. Finally, the perceived baseline of CO2 in the Atmosphere as of 1800 is 282.98 PPM. However, there is a range of Numbers used by various sources in the amount 275 PPM of CO2 in the Atmosphere up to around 290 PPM +/- 40NL has calculated this number to be (282.98) as a useful basline, based on data from NOAA. According to NOAA Atmospheric CO2 rose by approximately 50.36 PPM between 1800 and 1974. There are links provided below to various data sets from NOAA.

At one point CO2 was measured in approximately 226 locations around the Globe. However, CO2 is currently collected in only a few location with The Mauna Loa Observartory in Hawaii being one of them.

Here at 40NL we have created our own Table in order to reference the Increase in CO2. While CO2 has increased it is unclear if CO2 is directly affects temperature or if the increase in temperature is a Rebound Effect from the Little Ice Age (LIA) Also, under dispute is wheter or not CO2 follows temperature or temperature follows CO2.

While it has been alledged that CO2 Forces or Drives Climate this has not been proven and not a factual statement. However, using the current data provided here one can make many different conclusions based on the current aount of CO2 in the Atmosphere. It is completely inappropriate that the IPCC and others claim that CO2 Drives Climate based on one data set. At 40NL and Rapid Cooling we will continue to study and analyize the data.
