Cloud and surface albedo feedbacks reshape 21st century warming in...
The relative importance of radiative feedbacks and emissions scenarios in controlling surface warming patterns is challenging to quantify across model generations. We analyze...- publication PDF

Is a bipolar seesaw consistent with observed Antarctic climate variability...
A bipolar seesaw of Arctic and Antarctic temperature anomalies has been reported to be evident in instrumental data on decadal timescales during the last century. This finding...- publication PDF

Potential for Southern Hemisphere climate surprises
Climate model results suggest that future climate change in Antarctica will be accompanied by continued strengthening and poleward contraction of the Southern Ocean westerly...- publication PDF

A twentieth century perspective on summer Antarctic pressure change and...
During the late twentieth century, the Antarctic atmospheric circulation has changed and significantly influenced the overall Antarctic climate, through processes including a...- 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

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

Tropically driven and externally forced patterns of Antarctic sea ice...
Recent work suggests that natural variability has played a significant role in the increase of Antarctic sea ice extent during 1979-2013. The ice extent has responded strongly...- 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

Anthropogenic and internal drivers of wind changes over the Amundsen Sea,...
Ocean-driven ice loss from the West Antarctic Ice Sheet is asignificant contributor to sea-level rise. Recent ocean variability in theAmundsen Sea is controlled by near-surface...- publication PDF

Seasonal Antarctic pressure variability during the twentieth century from...
As most permanent observations in Antarctica started in the 1950s, understanding Antarctic climate variations throughout the twentieth century remains a challenge. To address...- publication PDF

Surface-atmosphere decoupling limits accumulation at Summit, Greenland
Despite rapid melting in the coastal regions of the Greenland Ice Sheet, a significant area (~40%) of the ice sheet rarely experiences surface melting. In these regions, the...- publication PDF
