It's looking very bad these last few weeks at the Mauna Loa carbon dioxide observatory.

4. Here's a graphic presentation

I used the same Mauna Loa data set as NNadir: http://www.esrl.noaa.gov/gmd/ccgg/trends/data.html

The first graph is a straight plot of annual CO2 increases. Note that both the linear trend and five year moving average clearly show an increasing rate of accumulation.



The next one shows only weeks whose annual increase was over 3.8 ppmv. Keeping in mind that 1998 was an anomalous year, the increasing frequency of such excursions is clear.
