"you seem to forget, that in return, the Europeans carried home the 'French Disease'"

You seem to forget this was about the effects of population collapse on global CO2 levels and temperatures. The paragraph after yours begins and ends with
"These episodes of abandonment and reforestation are reflected by reductions in CO2 levels recorded in ice cores".
It's a short paragraph.

If you had gone to the link, it was followed by


Population decreases and CO2 decreases recorded in ice cores from the Law Dome over the last 2000 years alongside global temperatures, Total Solar Irradiance, and major volcanic eruptions. Population and CO2 redrawn from Ruddiman 2014 " Earth Transformed" figure E-6 (W H Freeman), Temperature anomaly redrawn from Marcott et al 2013 figure S11(c), Volcanic sulfate redrawn from Sigl et al 2013, TSI redrawn from Steinhilber et al 2009 (0=1986 (1365.57 Wm-2)).

Calculations of the American population collapse suggest that about 37 billion tons of carbon was captured and sequestered from the atmosphere at that time. This is a staggering quantity of CO2 drawdown over such a short time, and likely contributed to the cooling of the Little Ice Age (see the figure above).
