A tropical mechanism for Northern Hemisphere deglaciation by Rodgers, K, Lohmann, G, Lorenz, S, Schneider, R, Henderson, G

“…This implies that tropical SSTs could play a more important role in melting ice sheets in the Northern Hemisphere than in reforming them, possibly providing a mechanism which could help to explain the rapidity of deglaciation relative to glacial inception. © 2003 by the American Geophysical Union.…”

Evidence from U-Th dating against Northern Hemisphere forcing of the penultimate deglaciation by Henderson, G, Slowey, N

“…Milankovitch proposed that summer insolation at mid-latitudes in the Northern Hemisphere directly causes the ice-age climate cycles. …”

Recognition of non-Milankovitch sea-level highstands at 185 and 343 thousand years ago from U-Th dating of Bahamas sediment by Henderson, G, Robinson, L, Cox, K, Thomas, A

“…This is ≈8 ka prior to the date expected if this warm period were driven by northern-hemisphere summer insolation. © 2006 Elsevier Ltd. …”

Penultimate deglacial sea-level timing from uranium/thorium dating of Tahitian corals. by Thomas, A, Henderson, G, Deschamps, P, Yokoyama, Y, Mason, A, Bard, E, Hamelin, B, Durand, N, Camoin, G

“…The coral-derived age for the last deglaciation is consistent with climate change forced by Northern Hemisphere summer insolation (NHI), but the timing of the penultimate deglaciation is more controversial. …”

Increased seasonality in the Western Mediterranean during the last glacial from limpet shell geochemistry by Ferguson, J, Henderson, G, Fa, D, Finlayson, J, Charnley, N

“…These extra-tropical seasonal-resolution SST records for the last glacial suggest that the presence of large ice-sheets in the northern hemisphere enhances winter cooling. This result also indicates that seasonality in the Mediterranean is not well-represented in most palaeoclimate models, which typically show little change in seasonal amplitude, and provides a new test for the accuracy of climate models. © 2011 Elsevier B.V.…”

Moisture variability in the southwestern United States linked to abrupt glacial climate change by Wagner, J, Cole, J, Beck, J, Patchett, P, Henderson, G, Barnett, H

“…These changes probably arose from interactions between Northern Hemisphere ice sheets and circulation in the North Atlantic Ocean, but the rapid and widespread propagation of these changes requires a large-scale atmospheric response whose details remain unclear4-7. …”

Links between the East Asian monsoon and North Atlantic climate during the 8,200 year event by Liu, Y, Henderson, G, Hu, C, Mason, A, Charnley, N, Johnson, K, Xie, S

“…An abrupt cooling event in the North Atlantic region 8,200 years ago affected climate throughout the Northern Hemisphere. The event is well constrained in Greenland ice cores, but lack of resolution in records from other regions has challenged our understanding of the timing and nature of the associated teleconnections. …”

The sequence of events surrounding Termination II and their implications for the cause of glacial-interglacial CO2 changes by Broecker, W, Henderson, G

“…The synchronous change of atmospheric CO2 and southern hemisphere temperature thus preceded the melting of the northern hemisphere ice sheets. This observation, coupled with the fact that nutrient reorganization in the North Atlantic occurs with or after the sea level rise, eliminates many scenarios proposed to explain the CO2 rise, including those which rely on sea level change, conveyor-related nutrient redistribution, or North Atlantic cooling. …”

U-Th dating of carbonate platform and slope sediments by Henderson, G, Slowey, N, Fleisher, M

“…This date is ≈8 kyr before the peak in northern hemisphere insolation and suggests that deglaciation is initiated by a mechanism in the southern hemisphere or tropics. …”

Advection and removal of Pb-210 and stable Pb isotopes in the oceans: A general circulation model study by Henderson, G, Maier-Reimer, E

“…And the model suggests natural Pb concentrations in the Northern Hemisphere an order of magnitude higher than in the Southern Hemisphere. …”

Reconstructing past flow rates of southern component water masses using sedimentary 231Pa/230Th by Hickey, B

“…</p> <p>On millenial timescales, ²³¹Pa/²³⁰Th values in deep cores GeoB 2109 and GeoB 2112 (4010 m) indicate enhanced production of AABW during northern hemisphere stadials, when variations in ²³¹Pa/²³⁰Th records are of opposite sign between hemispheres, supporting a possible bipolar seesaw relationship in deep water formation between hemispheres. …”
