Soils emitting more Carbon Dioxide from Nature.com

Unknown cause

The extra soil emissions could come from two types of sources: microbes and plants. If plant roots are emitting more carbon dioxide, the additional flux could be balanced by increasing rates of photosynthesis, resulting in no net increase in atmospheric carbon dioxide.

In contrast, warming soils could prompt microbes to break down old sources of carbon that have been locked away for a long time. This would cause a net increase in the atmosphere's store of carbon dioxide.

Although the study shows an increase in respiration, it can't distinguish between the two potential causes.

Would it be too much to speculate as to whether another possibility exists, which is that vegetation is dying back at an accelerating rate from exposure to toxic greenhouse gases, rotting into the soils, and this could account for the detection of higher rates of CO2 emissions?

No....never mind...just watch the movie.
