My interest in connections between climate and biology includes the terrestrial biosphere. Through collaborations with ecologists I have completed a study of the thermal impacts of climate change on the fitness of terrestrial ectotherms. By merging global patterns of climate variability and change with a body of work in empirical physiology we present simple models for the impact of climate change on species fitness and persistence across latitude. Our results have questioned the conventional wisdom that the high-latitude amplification of climate change should be reflected in demographic patterns of biological impact, suggestion instead that tropical species may be most susceptible to climate warming. This work connects to many broad questions about the relationships between global patterns of climate variability, biodiversity, and physiological adaptation to environmental change.
