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

Recent Antarctic sea ice trends in the context of Southern Ocean surface...
This study compares the distribution of surface climate trends over the Southern Ocean in austral summer between 1979-2011 and 1950-1978, using a wide variety of data sets...- publication PDF

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

No consistent simulated trends in the Atlantic Meridional Overturning...
The Atlantic Meridional Overturning Circulation (AMOC) is a key feature of the North Atlantic with global ocean impacts. The AMOC's response to past changes in forcings during...- publication PDF

Artifacts in century-length atmospheric and coupled reanalyses over...
Enabled by advances in data assimilation and the digitization of historical observations, atmospheric reanalysis products that span the entire twentieth century provide valuable...- publication PDF

Pattern recognition methods to separate forced responses from internal...
Ensembles of climate model simulations are commonly used to separate externally forced climate change from internal variability. However, much of the information gained from...- publication PDF

Antarctic and Southern Ocean surface temperatures in CMIP5 models in the...
This study examines the biases, intermodel spread, and intermodel range of surface air temperature (SAT) across the Antarctic ice sheet and Southern Ocean in 26 structurally...- 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

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

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

COVID‐19 crisis reduces free tropospheric ozone across the Northern Hemisphere
Throughout spring and summer 2020, ozone stations in the northern extratropics recorded unusually low ozone in the free troposphere. From April to August, and from 1 to 8...- publication PDF
