Climate change is already having a profound effect on vulnerable ecosystems worldwide.  If nothing is done to reduce the rate of global warming, researchers estimate that nearly two thirds of the world's most common species of plants, and one-third of animal species will lose half their climatic range by 2080 , resulting in declining biodiversity and profound impacts on human populations that depend upon them.  Sequoia utilizes a multidisciplinary scientific approach to study the early warning indicators of climate change in order to inform community decision-making and adaptive responses.  Since 2001, Sequoia has pioneered projects to advance innovative laboratory techniques, study changes in species affected by climate change, and collect and synthesize data on habitat modification.
