CO₂ 2008 - There is something going on!

Ernst-Georg Beck, Dipl. Biol. 4-2008

During the last two years several CO₂ measuring stations in the northern hemisphere accessible at WDCGG (World Data Center of Greenhouse gases) and NOAA show a change in trend observed trough the years.

An investigation of several updated graphs available reveals, that this changes are currently especially noticable for the northern hemisphere (April 2008). Following a selection of inspected charts for mostly continental stations:

1. Mauna Loa (Hawaii) 19,5N 155W, which is the worlds reference:

2. Park Falls USA, 45N 90W

3. Summit, Greenland; 72 N 38 W

4. Schauinsland Germany 48 W 7,9 E

5. Hegyhatsal Hungary, 47 N 16,6 E

6. Pallas-Sammaltunturi, Finland 68N 24 E

7. Ulaan Uul, Mongolia 44N, 111E

8. Anmyeon-do Korea, 37N 126 E.

This is most interesting because of the temperature trend at the moment which indicates some sort of a turning point, peaking about 2003.

If we assume temperature will further drop down and has passed the peak and the current CO2 trend will go on and indicate a turning point too then the following calculations will give us an impression whats going on at the moment.

Retired physicist Horst Bochert, Mainz (Germany;  Bcht01@aol.com ) calculated a time lag of two years from current data:

My own analysis of historical data according to my E&E paper Vol 18/3, 2007 and http://www.biokurs.de/treibhaus/180CO2_supp.htm indicate a turning point within 5 years. This is confirmed by all CO2 peaks in the last 200 years especailly the larger ones: about 1825, 1857 and 1942.

I have further analysed the the change of the seasonal variability  of CO₂ measured at several stations. Here are the results out a dozen inspected:

Changes in seasonal variation at different stations:

a) Marine stations , Polar stations –Remark: reaching ahigher turning point from a lower level

b) Continental stations –Remark: reaching a  lower turning point from a higher level

It seem that a variation turning point will be achieved within the next years.

As a consequence and when my analysis hold we are facing a further CO₂ turning point in history within the next years.
