The Last Millennium Reanalysis (LMR) utilizes an ensemble methodology to assimilate
paleoclimate data for the production of annually resolved climate field reconstructions of the …

Megadroughts are notable manifestations of the American Southwest, but not so much of the
European climate. By using long-term hydrological and meteorological observations, as well …

Despite increased Atlantic hurricane risk, projected trends in hurricane frequency in the
warming climate are still highly uncertain, mainly due to short instrumental record that limits …

Attribution and prediction of global and regional warming requires a better understanding of
the magnitude and spatial characteristics of internal global mean surface air temperature …

Understanding the response of tropical cyclone precipitation to ongoing climate change is
essential to determine associated flood risk. However, instrumental records are short-term …

Large uncertainties exist in climate model projections of the Asian summer monsoon (ASM).
The El Niño‐Southern Oscillation (ENSO) is an important modulator of the ASM, but the …

Using an assemblage of four ice cores collected around the Pacific basin, one of the first
basinwide histories of Pacific climate variability has been created. This ice core–derived …

Reconstructing hydroclimate over the Common Era is essential for understanding the
dominant mechanisms of precipitation change and improving climate model projections …

We describe a new El Niño–Southern Oscillation (ENSO) index that we call the Ensemble
Oceanic Niño Index (Ensemble ONI). Ensemble ONI uses monthly sea surface temperature …

The American West exemplifies drought-sensitive regions with growing populations.
Paleoclimate investigations have documented severe droughts in this region before …
