19:(born July 8, 1939) is an American ecologist and Professor of the Graduate School in the Energy and Resources Group at the University of California at Berkeley. His work includes investigation into a maximum entropy theory of ecology and long-term experiments on the effects of climate change on alpine ecology.

Harte has spoken out on the policy implications of his global warming research to the public on numerous occasions, notably in a filmed 2022 presentation to the
Central Colorado Humanists. With his wife, Mary Ellen (Mel) Harte, he co-authored the first free online book on climate change and policy in

The project used a linear array of 10 experimental plots that alternated between unheated (control) and heated plots, where the soil and vegetation of the latter were

Harte found that spring snowmelt occurred 2–3 weeks earlier in the heated plots. Heated subalpine meadow plots were greatly impacted and started transforming from non-woody flowering plants (forbs) towards more arid sagebrush habitat. Major findings included showing that this resulted in a loss of
