Insolation values for the climate of the last 10 million years

Rapid early Holocene deglaciation of the Laurentide ice sheet

“…In particular, the behavior of terrestrial ice sheets under climates warmer than present affords potential insight into the future behavior of the Greenland Ice Sheet. During the early Holocene, enhanced boreal summer insolation 6 (Fig. 1a) warmed Northern Hemisphere summers by several degrees, presumably driving retreat of the Laurentide Ice Sheet (LIS) [7][8][9] .…”

Connecting local environmental sequences to global climate patterns: evidence from the hominin-bearing Hadar Formation, Ethiopia

“…The percentage of eolian dust from ODP sites 721/722 in the Arabian Sea was used as a proxy for East African climate change, specifically aridity and patterns in arid-humid climate cycles (deMenocal, 1995(deMenocal, , 2004. Eccentricity modulated precession and summer solar insolation (July, 15° N) were calculated from Berger and Loutre (1991).…”

“…D) Timescaled sequence of depositional environments of the pre-disconformity Hadar Formation. E) Summer (July) solar insolation record at 15° N. (Berger and Loutre, 1991). F) Record of eccentricity modulated precession (Berger and Loutre, 1991).…”

“…E) Summer (July) solar insolation record at 15° N. (Berger and Loutre, 1991). F) Record of eccentricity modulated precession (Berger and Loutre, 1991). G) Generalized pattern of climate variability between 2.9•3.45 Ma.…”

Quantifying paleoprecipitation of the Luochuan and Sanmenxia Loess on the Chinese Loess Plateau

“…In this study, MAP of LC S1 is 720 mm and is quite similar to the result above. (Petit et al, 1999) and Dome C (Siegenthaler et al, 2005); b)Benthic δ 18 O stack LR04 (Lisiecki and Raymo, 2005); c) 21st June insolation data at 65°N (Berger and Loutre, 1991); d) glacial (yellow) and interglacial (red) MAPs of LC; e) glacial (yellow) and interglacial (red) MAPs of SMX; f) MAP differences between LC and SMX; S5 is divided into three intervals. In both LC and SMX, reconstructed MAPs correlate well with corresponding maximum χ FD and ARM (Fig.…”
