LeClaire AM, Powell EN, Mann R, Hemeon KM, Pace SM, Sower JR, Redmond TE (2022) Historical biogeographic range shifts and the influence of climate change climate change
Climate change includes both global warming driven by human-induced emissions of greenhouse gases and the resulting large-scale shifts in weather patterns. Though there have been previous periods of climatic change, since the mid-20th century humans have had an unprecedented impact on Earth's climate system and caused change on a global scale.
