Description: A longstanding question in biogeography is how long-lived plants such as trees kept pace with climate changes of the past. The question is also relevant today as climate change accelerates and habitats become fragmented. To help address this question, scientists have studied two facets of the problem: 1) How fast can plants disperse and 2) How fast are climates being displaced across landscapes? Here I review both facets of the problem. I will focus particularly on new approaches to quantifying the rate of climate change that account for climatic connectivity – the ability of landscapes to promote or hinder species movement in response to a changing climate.
