This indicated a massive decrease in the clearing of forests by burning to create more land for crops. While the population recovered (remember, Europe lost 20-30 million people in the span of six years), abandoned land began to regrow. Whole new forests sprouted, sucking CO2 out of the atmosphere, effectively removing layers from the Earth's thermal blanket. Moreover, their data aligns nearly perfectly (or so they say) with other information (heavy/light carbon isotope ratios) detailing the drop in atmospheric CO2 at the same time.

This (above) is the point that I thought was supporting.
I think the dates for LIA in that link are way off, though.
But with the correct dates, it supports the idea even more--though I'm not sure "how" their data lines up with "which" dates....
...or words to that effect.
