Uncertainties in tree-ring-based climate reconstructions probed
Uncertainties tree-ring-based climate reconstructions
2016/2/22
Current approaches to reconstructing past climate by using tree-ring data need to be improved on so that they can better take uncertainty into account, new University of Otago-led suggests.Tree growth...
Past temperature reconstructions from deep ice cores: relevance for future climate change
deep ice cores future climate change
2008/11/11
Ice cores provide unique archives of past climate and environmental changes based only on physical processes. Quantitative temperature reconstructions are essential for the comparison between ice core...
Paleoclimatic reconstructions in western Canada from boreholetemperature logs: surface air temperature forcing and groundwater flow
paleoclimatic western Canada boreholetemperature
2008/11/10
Modelling of surface temperature change effect on temperature vs.~depth and temperature-depth logs in Western Canada Sedimentary Basin show that SAT (surface air temperature) forcing is the main driv...
Selection of borehole temperature depth profiles for regional climate reconstructions
borehole temperature regional climate
2008/11/6
Borehole temperature depth profiles are commonly used to infer time variations in the ground surface temperature on centennial time scales. We compare different procedures to obtain a regional ground ...
The skill of proxy-based reconstructions of Northern hemisphere temperature is reassessed. Using an almost complete set of proxy and instrumental data of the past 130 years a multi-crossvalidation is ...
Numerical reconstructions of the Northern Hemisphere ice sheets through the last glacial-interglacial cycle
Northern Hemisphere ice glacial-interglacial cycle
2008/11/4
A 3-dimensional thermo-mechanical ice-sheet model is used to simulate the evolution of the Northern Hemisphere ice sheets through the last glacial-interglacial cycle. The ice-sheet model is forced by...
