Global Signatures and Dynamical Origins of the Little Ice Age and Medieval Climate Anomaly
TLDR
The Medieval period is found to display warmth that matches or exceeds that of the past decade in some regions, but which falls well below recent levels globally, and the Little Ice Age is marked by a tendency for La Niña–like conditions in the tropical Pacific. Expand
Northern Hemisphere Temperatures During the Past Millennium: Inferences, Uncertainties, and Limitations
Building on recent studies, we attempt hemispheric temperature reconstructions with proxy data networks for the past millennium. We focus not just on the reconstructions, but the uncertaintiesExpand
Proxy-based reconstructions of hemispheric and global surface temperature variations over the past two millennia
TLDR
The results extend previous conclusions that recent Northern Hemisphere surface temperature increases are likely anomalous in a long-term context to at least the past 1,700 years, but with additional strong caveats. Expand
Reconstruction of solar irradiance since 1610: Implications for climate change
Solar total and ultraviolet (UV) irradiances are reconstructed annually from 1610 to the present. This epoch includes the Maunder Minimum of anomalously low solar activity (circa 1645-1715) and theExpand
Climate change and tropical Andean glaciers: Past, present and future
ARTICLE I NFO Observations on glacier extent from Ecuador, Peru and Bolivia give a detailed and unequivocal account of rapid shrinkage of tropical Andean glaciers since the Little Ice Age (LIA). ThisExpand
Global-scale temperature patterns and climate forcing over the past six centuries
Spatially resolved global reconstructions of annual surface temperature patterns over the past six centuries are based on the multivariate calibration of widely distributed high-resolution proxyExpand

Arctic Environmental Change of the Last Four Centuries
A compilation of paleoclimate records from lake sediments, trees, glaciers, and marine sediments provides a view of circum-Arctic environmental variability over the last 400 years. From 1840 to theExpand
Interannual climate variability in the Central Andes and its relation to tropical Pacific and Atlantic forcing
The main spatiotemporal modes of interannual temperature and austral summer (DJF) precipitation variability in the Central Andes are identified based on a two-way principal compo- nent analysis (PCA)Expand
Threats to Water Supplies in the Tropical Andes
TLDR
The climate models predict that greenhouse warming will cause temperatures to rise faster at higher than at lower altitudes, with potentially grave consequences for water supplies. Expand
