Climate Warming Improves Oxygen Mixing in a High-Altitude Lake
Long term weather and lake data from a high elevation lake in the Alps demonstrate that climate warming may actually improve the ability of high-altitude deep lakes to mix their waters.

Southern California Climate Change over 100,000 Years
Researchers used a sediment core from a lake in California’s San Bernardino Mountains to track the effect of climate on vegetation, fire, and erosion between about 120,000 and 15,000 years ago.
