I

Layers # 1 and 2/3 from Section 1; Layer # 1 from Section 2

Cold and rainy

A cold and dry climate between 40,000 and 50,000 yr BP in Salitre [2] .

51,780 ± 400 ¹⁴C yr BP.

II

Layers # 4 and 5 from Section 1; Layer # 1 from Section 3

Cold and wet

An increase in moisture at low temperatures as from 45,000 yr BP in Salitre and Serra Negra [1] [2] .

Between 34,700 ± 5000 and 48,333 ± 370 ¹⁴C yr BP.

III

Layers # 6, 7 and 8 from Section 1; Layers # 2 - 15 from Section 2; Layers # 2 and 3 from Section 3

Seasonal and gradually warming

A slow decrease in vegetation as from 36,700 yr BP in São Paulo [8] ; Seasonality during this period in Serra Negra [1] ; Stable water levels in the Salitre basin between 33,000 and 40,000 yr BP [2] . However, both records [1] [2] reported an increase in temperature during this period. A more seasonal climate is suggested from 28.300 to 32,000 yr BP in Cromínia [3] [4] .

Between 27,500 ± 4000 and 34,700 ± 5000 yr BP.

IV

Layers # 9-14 from Section 1; Layers # 16 from Section 2; Layers # 4 - 13 from Section 3

Cold and wet

Expansion of the Atlantic forest and high humidity in the period between 28,225 and 30,400 yr BP, in the region of São Paulo [8] ; Presence for the Cromínia deposit of a shallow lake surrounded by open countryside with a wetter and probably cooler period between 20,000 and 27,000 yr BP, when compared to the present [3] [4] ; The same was indicated for Águas Emendadas between 21,000 and 24,000 yr BP [6] . Higher rainfall in a slightly cooler and less seasonal climate between 26,206 and 28,166 yr BP [27] .

<27,500 ± 4000 yr BP.

V

Layers # 15 - 18 from Section 1
