As human activities lead to rising greenhouse gas concentrations in Earth’s atmosphere, less incoming solar energy is released back into space, causing a net energy gain that increases global temperatures. Climate change will be an important driver of biodiversity loss into the foreseeable future. Habitat degradation, phenological shifts and ecosystem change are expected to result in an increasing number of...
