- Coupled, decoupled, and abrupt responses of vegetation to climate across timescales.

We developed a spectral analysis-based approach that provides detailed estimates of the timescales at which vegetation tracks climate change, from 10 to 10 years. We report dynamic similarity of vegetation and climate even at centennial frequencies (149 to 18,012 year, that is, one cycle per 149 to 18,012 years). A breakpoint in vegetation turnover (797 year) matches a breakpoint between stochastic and autocorrelated climate processes, suggesting that ecological dynamics are governed by climate across these frequencies. Heightened vegetation turnover at millennial frequencies (4650 year) highlights the risk of abrupt responses to climate change, whereas vegetation-climate decoupling at frequencies >149 year may indicate long-lasting consequences of anthropogenic climate change for ecosystem function and biodiversity.
