Author(s): Pistone, K; Eisenman, I; Ramanathan, V | Abstract: ©2019. American Geophysical Union. All Rights Reserved. During recent decades, there has been dramatic Arctic sea ice retreat. This has reduced the top-of-atmosphere albedo, adding more solar energy to the climate system. There is substantial uncertainty regarding how much ice retreat and associated solar heating will occur in the future. This is relevant to future climate projections, including the timescale for reaching global…

An Estimate of the Surface Pollution of the Arctic Sea Ice
The Arctic sea ice represents an important energy reservoir for the climate of the northern hemisphere. The shrinking of the polar ice in the past decades decreases the stored energy and raises
Arctic sea ice and snow cover albedo variability and trends during the last three decades
Abstract The aim of the present study is to assess the full effect on the albedo of both sea ice extent decrease and snowline retreat in the Arctic during the last three decades. Averaged over the
Recent strengthening of snow and ice albedo feedback driven by Antarctic sea-ice loss
The decline of the Arctic cryosphere during recent decades has lowered the region’s surface albedo, reducing its ability to reflect solar radiation back to space. It is not clear what role the
Less climatic resilience in the Arctic
Abstract Twenty years ago the Arctic system was more resilient than now as sea ice was three times thicker than today. Heavier and more persistent sea ice provided a buffer against the influence of
Unraveling driving forces explaining significant reduction in satellite-inferred Arctic surface albedo since the 1980s
TLDR
It is shown that the decrease in snow cover fraction is primarily driven by the increase in surface air temperature, followed by declining snowfall, soot heating has not been the driver of changes in the Arctic snow cover, ice cover, and surface albedo since the 1980s.
Sustaining the Arctic in Order to Sustain the Global Climate System
The unraveling of the Arctic is bad enough for the Arctic itself, but it will have enormous consequences for the entire planet since the Arctic is a crucial component of the global climate system.
Identifying the Causal Role of CO2 during the Ice Ages
We investigate past climate variability over the Ice Ages, where a simultaneous-equations system is developed to characterize land ice volume, temperature and atmospheric CO2 levels as non-linear
How Should a Global Carbon Budget be Estimated?
The Intergovernmental Panel on Climate Change (IPCC), the authority for estimating a carbon budget for keeping to the Paris Agreement’s 1.5—2°C target for limiting global warming, has indicated a
Optimal combination of Arctic sea ice extent measures: A dynamic factor modeling approach
Abstract The diminishing extent of Arctic sea ice is a key indicator of climate change as well as being an accelerant for future global warming. Since 1978, Arctic sea ice has been measured using

Observational determination of albedo decrease caused by vanishing Arctic sea ice
TLDR
This analysis directly quantifies how much the Arctic as viewed from space has darkened in response to the recent sea ice retreat, finding that this decline has caused 6.4 ± 0.9 W/m2 of radiative heating since 1979, considerably larger than expectations from models and recent less direct estimates.
The Global Radiative Impact of the Sea-Ice-Albedo Feedback in the Arctic
[1] A simple method for estimating the global radiative forcing caused by the sea ice–albedo feedback in the Arctic is presented. It is based on observations of cloud cover, sea ice concentration,
Sea Ice Trends in Climate Models Only Accurate in Runs with Biased Global Warming
AbstractObservations indicate that the Arctic sea ice cover is rapidly retreating while the Antarctic sea ice cover is steadily expanding. State-of-the-art climate models, by contrast, typically
Assessment of Sea Ice Albedo Radiative Forcing and Feedback over the Northern Hemisphere from 1982 to 2009 Using Satellite and Reanalysis Data
AbstractThe decreasing surface albedo caused by continuously retreating sea ice over Arctic plays a critical role in Arctic warming amplification. However, the quantification of the change in
Ice-free Arctic projections under the Paris Agreement
TLDR
Sea-ice projections under stabilized global warming with an Earth System Model correct biases in mean sea-ice coverage by constraining with observations, and suggest that the benefits of going from 2.0 °C to 1.5‬C stabilized warming are substantial.
Observed Arctic sea-ice loss directly follows anthropogenic CO2 emission
TLDR
A robust linear relationship between monthly-mean September sea-ice area and cumulative carbon dioxide (CO2) emissions allowed Notz and Stroeve to infer the future evolution of Arctic summer sea ice directly from the observational record.
Recent and future changes in Arctic sea ice simulated by the HadCM3 AOGCM

Geographic muting of changes in the Arctic sea ice cover
The seasonal cycle in Arctic sea ice extent is asymmetric. Its amplitude has grown in recent decades as the ice has retreated more rapidly in summer than in winter. These seasonal disparities have
Do Climate Models Underestimate the Sensitivity of Northern Hemisphere Sea Ice Cover
AbstractThe sensitivity of Northern Hemisphere sea ice cover to global temperature change is examined in a group of climate models and in the satellite-era observations. The models are found to have
