@spudseven @tan123 2/ The paper uses rough estimates of population (ranges of 2x or 3x) plus even more speculative estimates of land use change to attribute 20-87% of the estimated 0.15∘C drop in surface air temp to anthro effects. As usual, no error bars.

#climatechange"This resulted in secondary succession of 55.8 Mha (IQR 39.0–78.4 Mha) of abandoned land, sequestering 7.4 Pg C (IQR 4.9–10.8 Pg C), equivalent to a decline in atmospheric CO2 of 3.5 ppm"
