Summary
| Description |
English: Selected paleoclimate and glacial-advance proxies from western Canada. Top: July and January insolation at 50°N, expressed as difference from today's values. Middle: Summer temperature reconstructed from fossil chironomid assemblages. Points indicate the temperature anomaly from a 0–2 kyr base period, and the smooth line shows a locally weighted (loess) smoothing in a 600-yr window (Gavin et al. 2011).[1] Bottom: The LOI index is the Z score of the first principal component of the loss-on-ignition of sediments from four glacial-fed lakes in southwest British Columbia (Menounos et al. 2008).[2] High values correspond to more clastic input and times of glacier advances. Times and relative magnitude of five glacial advances on Mount Baker, Washington, are overlaid on the LOI index (Osborne et al. 2012).[3] Blue bars indicate time of regional glacial advances (Menounos et al. 2008).[2] YDC=Younger Dryas Chronozone.
