The anatomy of past abrupt warmings recorded in Greenland ice

Nature Communications, 2021
Palaeodata resolution and dating limit the study of the sequence of changes across Earth during past abrupt warmings. Here, the authors show tight decadal-scale coupling between Greenland climate, North Atlantic sea ice and atmospheric circulation during

Factors controlling the bifurcation structure of sea ice retreat [PDF]

, 2012
The contrast in surface albedo between sea ice and open ocean suggests the possibility of an unstable climate state flanked by two separate stable climate states. Previous studies using idealized single-column models and comprehensive climate models have

The impact of Arctic sea ice loss on mid-Holocene climate. [PDF]

, 2018
Mid-Holocene climate was characterized by strong summer solar heating that decreased Arctic sea ice cover. Motivated by recent studies identifying Arctic sea ice loss as a key driver of future climate change, we separate the influences of Arctic sea ice ...

Response of Pacific-sector Antarctic ice shelves to the El Niño/Southern Oscillation. [PDF]

, 2018
Satellite observations over the past two decades have revealed increasing loss of grounded ice in West Antarctica, associated with floating ice shelves that have been thinning.

The impact of a seasonally ice free Arctic Ocean on the temperature, precipitation and surface mass balance of Svalbard [PDF]

, 2012
The observed decline in summer sea ice extent since the 1970s is predicted to continue until the Arctic Ocean is seasonally ice free during the 21st Century. This will lead to a much perturbed Arctic climate with large changes in ocean surface energy flux.

Measurement report: Comprehensive seasonal study of the composition and sources of submicron aerosol during the JULIAC campaign in Germany [PDF]

Atmospheric Chemistry and Physics
The seasonal variations of aerosol sources and their atmospheric evolution are investigated using observations from the year-long JULIAC (Jülich Atmospheric Chemistry Project) campaign (January–November 2019) in Jülich, Germany.

An optimization-based approach to track the Asian summer monsoon anticyclone across daily and interannual variability [PDF]

Atmospheric Chemistry and Physics
The definition of the boundary of the Asian summer monsoon anticyclone (ASMA) in the upper troposphere-lower stratosphere (UTLS) (350–410 K) is a known challenge that highly impacts the information about the anticyclone's behavior and affects the results

Ice-sheet mass balance and climate change [PDF]

Nature, 2013
Since the 2007 Intergovernmental Panel on Climate Change Fourth Assessment Report, new observations of ice-sheet mass balance and improved computer simulations of ice-sheet response to continuing climate change have been published. Whereas Greenland is losing ice mass at an increasing pace, current Antarctic ice loss is likely to be less than some ...

Taking stock of arctic sea ice and climate [PDF]

, 2009
The relationship among the cause-and-effect of the Arctic atmosphere, sea ice, and ocean is discussed. The increased vulnerability of the Arctic system to anomalous atmospheric forcing can be argued from the perspective that recent ice loss is the result

Temperature-dependent rate coefficients for the reactions of OH radicals with selected alkanes, aromatic compounds, and monoterpenes [PDF]

Atmospheric Chemistry and Physics
The rate coefficients of the reaction of hydroxyl radicals (OH) with 12 different volatile organic compounds (VOCs), namely methane, ethane, propane, n-butane, methyl vinyl ketone (MVK), γ-terpinene, Δ3-carene, myrcene, toluene, o-xylene, m-xylene, and ...
