Thanks to those list readers who have replied offline. To be clear, I'm not being a data perfectionist or crank about this issue. I do think, however, that the substantial drawdown performed by photosynthesis each year highlights the possibility of reversing CO2 trends.
The un-corrected data look like this: http://d32ogoqmya1dw8.cloudfront.net/images/introgeo/interactive/examples/6yrco2.gif The challenge, then, is obviously to draw carbon into stable compounds in the soil which do not degrade and return to the atmosphere. Methods for making such sequestration work have been explored by many researchers and farmers, and are gaining credence. One influential Australian soil scientist, Dr. Christine Jones, describes a "liquid carbon pathway" by which plants in synergy with fungi can store humus (composed of large stable molecules) much deeper in soil than is generally appreciated. A good essay of hers on making agricultural land act as a carbon sink is at: http://www.amazingcarbon.com/PDF/JONES-SoilCarbon&Agriculture(18May10).pdf Brian Cartwright On Monday, December 8, 2014 8:02:50 AM UTC-5, Brian Cartwright wrote: > > http://climate.nasa.gov/vital-signs/carbon-dioxide/ > > CO2 levels here are "corrected for seasonal cycle".
