The Evidence for a Changing Previous HitClimateNext Hit Recorded in Ice Sheets and Mountain Glaciers

Glaciers are sensitive to numerous aspects of Previous HitclimateNext Hit, but their strongest relation is to summer temperatures. Through this connection, observations of glacier length can be used to reconstruct temperature history for the last few centuries, and this confirms the pattern and magnitude of 20th century warming inferred by other methods. Ice cores taken from high-altitude low-latitude glaciers provide - via their isotopic composition - an objective measure of Previous HitclimateNext Hit variability that suggests recent Previous HitclimateNext Hit is anomalous. These data also reveal connections between Previous HitclimateNext Hit and solar variability. In some places, retreat of glaciers is currently exposing organic material and sediments that were last exposed millennia ago. Current, ongoing changes of the polar ice sheets are related to increased air and ocean temperatures. These changes provide information about how polar land ice will be reduced as Previous HitclimateTop warms.
