Huascaran δO as an indicator of tropical climate during the Last Glacial Maximum
The interpretation of the isotopic composition of Andes tropical mountain glaciers is reconsidered using a simple Rayleigh distillation model. It is shown that Andes snowline depression and Huascaran ice core δO are consistent with a 3C drop in sea surface temperature during the Last Glacial Maximum, accompanied by an increase from 40% at present to 60% during the LGM in the annual mean proport...
متن کاملThe tropical lapse rate steepened during the Last Glacial Maximum
The gradient of air temperature with elevation (the temperature lapse rate) in the tropics is predicted to become less steep during the coming century as surface temperature rises, enhancing the threat of warming in high-mountain environments. However, the sensitivity of the lapse rate to climate change is uncertain because of poor constraints on high-elevation temperature during past climate s...
متن کاملQuantifying the Effects of Lower Sea Level on Tropical Pacific Climate during the Last Glacial Maximum
ACKNOWLEDGEMENTS First and foremost, I wish to thank my research advisor and co-advisor, Dr. Kim Cobb and Dr. Emanuele DiLorenzo. They have put a tremendous number of hours into this project while teaching me that conducting research is challenging, tiring, but more importantly, fun and inspiring. I also wish to thank Dr. Yen, both who introduced me to the world of academia. Working in both of ...
متن کاملThe Last Glacial Maximum.
We used 5704 14C, 10Be, and 3He ages that span the interval from 10,000 to 50,000 years ago (10 to 50 ka) to constrain the timing of the Last Glacial Maximum (LGM) in terms of global ice-sheet and mountain-glacier extent. Growth of the ice sheets to their maximum positions occurred between 33.0 and 26.5 ka in response to climate forcing from decreases in northern summer insolation, tropical Pac...
متن کاملEarly local last glacial maximum in the tropical Andes.
The local last glacial maximum in the tropical Andes was earlier and less extensive than previously thought, based on 106 cosmogenic ages (from beryllium-10 dating) from moraines in Peru and Bolivia. Glaciers reached their greatest extent in the last glacial cycle approximately 34,000 years before the present and were retreating by approximately 21,000 years before the present, implying that tr...
