Albedo evolution of seasonal Arctic sea ice
TLDR
In this paper, the authors examined the impact of seasonal ice cover on sea ice albedo and found that the shift from a multi-year to seasonal cover has significant implications for the heat and mass budget of the ice and for primary productivity in the upper ocean.Abstract:
[1] There is an ongoing shift in the Arctic sea ice cover from multiyear ice to seasonal ice. Here we examine the impact of this shift on sea ice albedo. Our analysis of observations from four years of field experiments indicates that seasonal ice undergoes an albedo evolution with seven phases; cold snow, melting snow, pond formation, pond drainage, pond evolution, open water, and freezeup. Once surface ice melt begins, seasonal ice albedos are consistently less than albedos for multiyear ice resulting in more solar heat absorbed in the ice and transmitted to the ocean. The shift from a multiyear to seasonal ice cover has significant implications for the heat and mass budget of the ice and for primary productivity in the upper ocean. There will be enhanced melting of the ice cover and an increase in the amount of sunlight available in the upper ocean.read more

Changes in Arctic Melt Season and Implications for Sea Ice Loss
Julienne Stroeve,Julienne Stroeve,Thorsten Markus,Linette N. Boisvert,Jack M. Miller,Andrew P. Barrett +5 more
TL;DR: In this article, the authors observed that the Arctic-wide melt season has lengthened at a rate of 5 days dec-1 from 1979 to 2013, dominated by later autumn freeze-up within the Kara, Laptev, East Siberian, Chukchi and Beaufort seas between 6 and 11 days dec(exp -1).

Ozone depletion and climate change: impacts on UV radiation

TL;DR: The Montreal Protocol is working, but it will take several decades for ozone to return to 1980 levels, and the phase-out of CFCs is currently tending to counteract the increases in surface temperature due to increased GHGs.

TL;DR: In this article, key observational indicators of climate change in the Arctic, most spanning a 47-year period (1971-2017) demonstrate fundamental changes among nine key elements of the Arctic system.

TL;DR: In this paper, the changes in sea ice are happening faster than models have projected and substantial uncertainties in the exact timing and high interannual variability will remain as sea ice decreases.

Seasonal evolution of the albedo of multiyear Arctic sea ice : The surface heat budget of arctic ocen (SHEBA)
TL;DR: In this paper, the authors measured spectral and wavelength-integrated albedo on multi-year sea ice from a 200m survey line from April through October and observed changes in the evolution of albedos.

Accelerated decline in the Arctic sea ice cover
TL;DR: For example, the extent and area of the Arctic sea ice reached minima on 14 September 2007 at 4.1 × 106 km2 and 3.6 × 106 cm2, respectively as discussed by the authors.

Arctic sea ice decline: Faster than forecast
TL;DR: In this paper, a multi-model ensemble mean time series provides a true representation of forced change by greenhouse gas (GHG) loading, 33-38% of the observed September trend from 1953-2006 is externally forced, growing to 47-57% from 1979-2006.

Perspectives on the Arctic's Shrinking Sea-Ice Cover
TL;DR: Although the large scatter between individual model simulations leads to much uncertainty as to when a seasonally ice-free Arctic Ocean might be realized, this transition to a new arctic state may be rapid once the ice thins to a more vulnerable state.

TL;DR: In this article, the decline of sea ice thickness in the Arctic Ocean from ICESat (2003-2008) is placed in the context of estimates from 42 years of submarine records (1958-2000) described by Rothrock et al. (1999, 2008).

A younger, thinner Arctic ice cover: Increased potential for rapid, extensive sea-ice loss

TL;DR: In this article, satellite-derived estimates of sea-ice age and thickness are combined to produce a proxy ice thickness record for 1982 to the present, showing that in addition to the well-documented loss of perennial ice cover as a whole, the amount of oldest and thickest ice within the remaining multiyear ice pack has declined significantly.
