Hi, I am a student at Brown University taking part to a class aiming to update Wikipedia articles based on the IPCC AR6. I recommend adding two paragraphs based on the assessed results from the IPCC AR6 report. The suggestions I make are the following:
I've cut out an outdated textblock from climate change and indigenous peoples. It might fit here although it's probably already here and with more up to date figures (?). This is the text block: ++++ According to satellite images, the Arctic region currently has the smallest area of ice in recorded history. [2] Climate change will lead to a faster rise in sea level, more frequent and increasingly intense storms and winds, and increased erosion from higher waves. [3] It additionally will lead to further decreases in the quantity of sea ice. [3] The albedo effect has had serious consequences with respect to the Arctic and the rest of the world. When ice melts, its light surface also disappears. [4] Lighter surfaces reflect more radiation, while darker surfaces absorb more radiation. [4] The conversion of sea ice to water makes more of the Earth's surface darker, further contributing to global warming as more radiation is absorbed. [4] This is known as a positive feedback loop. [4] Albedo is measured from a scale of 0 to 1, 0 corresponding to a perfect blackbody with absorbs all radiation and 1 corresponding to a body which reflects all incoming radiation. [5] From 1979 to 2011, the Arctic's overall albedo has decreased from 0.52 to 0.48, meaning it has overall had darker surfaces and absorbed more energy. [4] As of 2011, the Arctic ocean has received a further 6.4 +/- 0.9 W/m^2 of solar energy input. [4] Albedo is expected to decrease even further in the coming years. [6] Scientists have projected what is expected to happen should all of the Arctic summer sea-ice melted completely. If greenhouse gases are globally emitted as predicted, then the melting of the ice can potentially warm up the planet by approximately 0.2 °C. [6] +++ EMsmile ( talk) 13:50, 8 June 2022 (UTC)

There is still quite a long section on arctic sea ice decline in the article climate change in the Arctic. Should it perhaps be moved to here? Otherwise the two articles overlap too much? This article currently has higher pageviews than climate change in the Arctic. EMsmile ( talk) 13:57, 8 June 2022 (UTC)
Majority of sources are current. A few are over two decades old and could be possibly updated. SkyBrooke ( talk) 23:42, 24 January 2023 (UTC)
I don't have time to do it myself right now, so I am just putting it here: the lead should be expanded a bit to become a better summary of the entire article. In particular, it should have some summary statements from the sections about the impacts on humans and impacts on wildlife. The lead is currently still on the short side (288 words), so we do have space to expand it. I think it should be around 400 to 500 words long in the end. EMsmile ( talk) 09:10, 6 July 2023 (UTC)
The (currently 3rd) figure on the "death spiral" of Atlantic ice is misleading and should be removed. By plotting the linear data in a circular polar plot it (1) amplifies the perceived amount of decline, which perceivably correlates with the area instead of length in this figure, and (2) makes it very difficult to see the year-by-year changes.
In contrast the two lead images of the article (shown here too) are better, because they present the same information in a way that is more perceptively clear and follows standard conventions.
This is important because the literature discusses how sea ice decline has substantially reduced since 2007 (see https://www.science.org/doi/10.1126/science.adh5158, figure 1B). It is an important scientific question to understand this phenomenon, a phenomenon clearly visible in raw data, but obscured by the misleading graph.

@ RCraig09: Apols for the deletion, I was editing Kara Sea U-boat campaign and hadn't realied that I'd strayed into another article and disrupted it. Keith-264 ( talk) 22:47, 29 October 2023 (UTC)
Is this because sea ice extent is the same or higher than it was in 2004? NSIDC Figure 3, “Average Monthly Sea Ice Extent, 1979 - 2024”? 2603:9000:2500:C503:A12C:130A:E9EF:C982 ( talk) 02:05, 18 February 2024 (UTC)
