1,200 Years of Moisture Source Variability in Central America
Central American precipitation drives regional agricultural productivity and economic stability, yet poor constraints on past hydroclimate variability continue to restrict future forecasts, according to recent paleoclimate research. To understand these shifts, researchers examined a 1,200-year paleoclimate record from Lake Izabal in Guatemala, utilizing sedimentary plant wax hydrogen isotope ratios and XRF spectroscopy to reconstruct historic … Read more
