Centennial-scale climate change from decadally-paced explosive volcanism: A...
Northern Hemisphere summer cooling through the Holocene is largely driven by the steady decrease in summer insolation tied to the precession of the equinoxes. However,...- publication PDF

Climate data guide spurs discovery and understanding
Highly accurate and stable observations -- beyond those provided by routine weather monitoring -- are essential for understanding the behavior of the climate system, developing...- publication PDF

Climate response to large, high-latitude and low-latitude volcanic eruptions...
Explosive volcanism is known to be a leading natural cause of climate change. The second half of the 13th century was likely the most volcanically perturbed half-century of the...- publication PDF

Comparing the impacts of tropical SST variability and Polar stratospheric...
Westerly wind trends at 850 hPa over the Southern Ocean during 1979-2011 exhibit strong regional and seasonal asymmetries. On an annual basis, trends in the Pacific sector...- publication PDF

Improved clouds over Southern Ocean amplify Antarctic precipitation response...
Increasing precipitation on the Antarctic Ice Sheet (AIS) in a warming climate has the potential to partially mitigate Antarctica's contribution to sea level rise. We show that...- publication PDF
