That said, competitors have caught up to SteelSeries in terms of audio quality, offering larger 50mm drivers and more robust digital audio tweaks via software. The Arctic includes copious natural resources (oil, gas, minerals, fresh water, fish and, if the subarctic is included, forest) to which modern technology and the economic opening up of Russia have given significant new opportunities. The interest of the tourism industry is also on the increase. Vose, R. S. et al. Noaa’s merged land–ocean surface temperature analysis. Bull. Am. Meteorol. Soc. 93, 1677–1685 (2012). Upon ratification of the United Nations Convention on the Law of the Sea, a country has ten years to make claims to an extended continental shelf beyond its 200 nautical mile zone. [23] [28] Due to this, Norway (which ratified the convention in 1996), [29] Russia (ratified in 1997), [29] Canada (ratified in 2003) [29] and the Kingdom of Denmark (ratified in 2004) [29] launched projects to establish claims that certain sectors of the Arctic seabed should belong to their territories.

Because the sea ice loss is one of the main mechanisms causing AA, and given that up to 50% of the recent loss may be due to realization-dependent internal variability, a relevant follow-up question is whether the climate models are able to reproduce the magnitude of the observed AA over the past 40 years or so. Earlier studies have suggested that AA is indeed weaker in climate models than in observations 38, 39, 40, 41, but a comprehensive comparison between the observed and simulated AA ratio, using the most up-to-date observations and multiple climate model ensembles, has not yet been performed. The wireless dongle is actually a wired one instead of the USB drive-style dongle in most other wireless headsets. The dongle has a 3.4-foot USB Type-A cable, and the bottom of the unit has a PC/PlayStation switch and a pairing button. The Arctis 9 comes paired with the wireless dongle out of the box, making the unit mostly plug-and-play. I plugged it into my PC and was off to the races, no software installation required. The faster warming rate in the Arctic compared to the globe as a whole is nowadays considered a robust fact. The phenomenon, called Arctic or polar amplification (AA), can be seen in both instrumental observations 1, 2, 3 and climate models 4 as well as in paleoclimate proxy records 5.

The effects of doubling the CO 2 concentration on the climate of a general circulation model. J. Atmos. Sci. 32, 3–15 (1975). Previous studies have shown that CO 2-forced GCMs simulate similar advection of lower tropospheric warm anomalies from newly ice-free ocean regions in the Arctic to adjacent land regions: while summer season sea ice decline and ocean mixed layer warming in the Arctic directly cause (delayed) surface-amplified warming over the Arctic Ocean in fall and winter 7, warming over boreal land regions is primarily through warm air advection from the polar oceans 29. Therefore, when Antarctic orography is flattened, there is greater similarity between the poles in how advection of boundary layer air from newly ice-free ocean waters warms land areas in winter. Greater surface-amplified warming with flattened orography where L v is the latent heat of fusion, q is the specific humidity, C p is the specific heat of dry air at constant pressure, T is the temperature, g is the acceleration due to gravity, and Φ is the height relative to the geoid. When moist isentropes are flatter (as when Antarctic orography is flattened), air parcels gain less geopotential as they flow poleward, and therefore retain more moisture. This is also evident in the change in specific humidity with CO 2-doubling (Fig. 5, colors): the (poleward) gradient of this specific humidity change along a moist isentropic surface, ∇(∆ q) | θE, is greater with present-day Antarctic orography (panels a, c) than with flattened Antarctic orography (panels b, d), indicating that more moisture is lost along this trajectory with present-day orography than with flattened orography (compare, for example, the gradient of the change in specific humidity, denoted by the blue colors, along the 270 K moist isentrope in Fig. 5a, c with those in 5b, d).

The observations systematically indicate larger AA than CMIP6 models around the year. In all months, the observed AA 43 falls to the upper 25 % of the CMIP6 ensemble, and even to the top 5% in April, May, June, and August. The monthly comparison of observations to CMIP5 models indicate even more pronounced underestimation of AA, especially in the melting season (Fig. S 7). An interesting finding from Fig. 5 is the anomalously high observed AA in April. The high AA 43 in April is consistent in all four observational datasets (not shown), and has been reported also in the earlier studies 41, 50. However, while Hahn et al. 41 noted that the warming in April falls within the intermodel spread for CMIP6 in 1979–2014, we found that when normalized with global warming, the warming in April is distinctly outside the CMIP6 ensemble (Fig. 5). According to Hahn et al. 41, model biases in the reductions of spring snow cover may contribute to the discrepancy between observations and models in the melting season.

Due to the good agreement over the last 43 years, we next consider the average of these four datasets as an observational estimate. The observations indicate that, during 1979–2021, a large fraction of the Arctic Ocean was warming faster than 0.75 ∘C decade −1 (Fig. 1b), with a maximum warming in the Eurasian sector of the Arctic Ocean, near Svalbard and Novaya Zemlya. In this region, the temperature trend over 1979–2021 locally exceeds 1.25 ∘C decade −1 (Fig. 1b). In contrast, large continental regions in the North America and, to a lesser extent, in Western Siberia, do not manifest statistically significant trends in temperatures; however these regions are mainly located in mid-latitudes and are only indirectly affected by AA. The spatial patterns of temperature trends are broadly consistent across the individual observational datasets (Fig. S 2), with GISTEMP and HadCRUT5 showing somewhat less pronounced warming maxima near Svalbard and Bering Strait (Fig. S 2a and c) than BEST and ERA5.
