Abstract

For the first time in several years, the El Nino-Southern Oscillation did not dominate regional climate conditions around the globe. A weak La Niña dissipated to ENSO-neutral conditions by spring, and while El Nino appeared to be emerging during summer, this phase never fully developed as sea surface temperatures in the eastern equatorial Pacific uncharacteristically returned to neutral conditions. Nevertheless, other large-scale climate patterns and extreme weather events impacted various regions during the year. A negative phase of the Arctic Oscillation from mid-January to early February contributed to frigid conditions in parts of northern Africa, eastern Europe, and western Asia. A lack of rain during the 2012 wet season led to the worst drought in at least the past three decades for northeastern Brazil. Central North America also experienced one of its most severe droughts on record. The Caribbean observed a very wet dry season and it was the Sahel's wettest rainy season in 50 years. Overall, the 2012 average temperature across global land and ocean surfaces ranked among the 10 warmest years on record. The global land surface temperature alone was also among the 10 warmest on record. In the upper atmosphere, the average stratospheric temperature was record or near-record cold, depending on the dataset. After a 30-year warming trend from 1970 to 1999 for global sea surface temperatures, the period 2000-12 had little further trend. This may be linked to the prevalence of La Niña-like conditions during the 21st century. Heat content in the upper 700 m of the ocean remained near record high levels in 2012. Net increases from 2011 to 2012 were observed at 700-m to 2000-m depth and even in the abyssal ocean below. Following sharp decreases in global sea level in the first half of 2011 that were linked to the effects of La Niña, sea levels rebounded to reach records highs in 2012. The increased hydrological cycle seen in recent years continued, with more evaporation in drier locations and more precipitation in rainy areas. In a pattern that has held since 2004, salty areas of the ocean surfaces and subsurfaces were anomalously salty on average, while fresher areas were anomalously fresh. Global tropical cyclone activity during 2012 was near average, with a total of 84 storms compared with the 1981-2010 average of 89. Similar to 2010 and 2011, the North Atlantic was the only hurricane basin that experienced above-normal activity. In this basin, Sandy brought devastation to Cuba and parts of the eastern North American seaboard. All other basins experienced either near- or below-normal tropical cyclone activity. Only three tropical cyclones reached Category 5 intensity-all in the Western North Pacific basin. Of these, Super Typhoon Bopha became the only storm in the historical record to produce winds greater than 130 kt south of 7°N. It was also the costliest storm to affect the Philippines and killed more than 1000 residents. Minimum Arctic sea ice extent in September and Northern Hemisphere snow cover extent in June both reached new record lows. June snow cover extent is now declining at a faster rate (-17.6% per decade) than September sea ice extent (-13.0% per decade). Permafrost temperatures reached record high values in northernmost Alaska. A new melt extent record occurred on 11-12 July on the Greenland ice sheet; 97% of the ice sheet showed some form of melt, four times greater than the average melt for this time of year. The climate in Antarctica was relatively stable overall. The largest maximum sea ice extent since records begain in 1978 was observed in September 2012. In the stratosphere, warm air led to the second smallest ozone hole in the past two decades. Even so, the springtime ozone layer above Antarctica likely will not return to its early 1980s state until about 2060. Following a slight decline associated with the global financial crisis, global CO2 emissions from fossil fuel combustion and cement production reached a record 9.5 ± 0.5 Pg C in 2011 and a new record of 9.7 ± 0.5 Pg C is estimated for 2012. Atmospheric CO2 concentrations increased by 2.1 ppm in 2012, to 392.6 ppm. In spring 2012, for the first time, the atmospheric CO2 concentration exceeded 400 ppm at 7 of the 13 Arctic observation sites. Globally, other greenhouse gases including methane and nitrous oxide also continued to rise in concentration and the combined effect now represents a 32% increase in radiative forcing over a 1990 baseline. Concentrations of most ozone depleting substances continued to fall.

Abstract

Several large-scale climate patterns influenced climate conditions and weather patterns across the globe during 2010. The transition from a warm El Niño phase at the beginning of the year to a cool La Niña phase by July contributed to many notable events, ranging from record wetness across much of Australia to historically low Eastern Pacific basin and near-record high North Atlantic basin hurricane activity. The remaining five main hurricane basins experienced below- to well-below-normal tropical cyclone activity. The negative phase of the Arctic Oscillation was a major driver of Northern Hemisphere temperature patterns during 2009/10 winter and again in late 2010. It contributed to record snowfall and unusually low temperatures over much of northern Eurasia and parts of the United States, while bringing above-normal temperatures to the high northern latitudes. The February Arctic Oscillation Index value was the most negative since records began in 1950. The 2010 average global land and ocean surface temperature was among the two warmest years on record. The Arctic continued to warm at about twice the rate of lower latitudes. The eastern and tropical Pacific Ocean cooled about 1°C from 2009 to 2010, reflecting the transition from the 2009/10 El Niño to the 2010/11 La Niña. Ocean heat fluxes contributed to warm sea surface temperature anomalies in the North Atlantic and the tropical Indian and western Pacific Oceans. Global integrals of upper ocean heat content for the past several years have reached values consistently higher than for all prior times in the record, demonstrating the dominant role of the ocean in the Earth's energy budget. Deep and abyssal waters of Antarctic origin have also trended warmer on average since the early 1990s. Lower tropospheric temperatures typically lag ENSO surface fluctuations by two to four months, thus the 2010 temperature was dominated by the warm phase El Niño conditions that occurred during the latter half of 2009 and early 2010 and was second warmest on record. The stratosphere continued to be anomalously cool. Annual global precipitation over land areas was about five percent above normal. Precipitation over the ocean was drier than normal after a wet year in 2009. Overall, saltier (higher evaporation) regions of the ocean surface continue to be anomalously salty, and fresher (higher precipitation) regions continue to be anomalously fresh. This salinity pattern, which has held since at least 2004, suggests an increase in the hydrological cycle. Sea ice conditions in the Arctic were significantly different than those in the Antarctic during the year. The annual minimum ice extent in the Arctic-reached in September-was the third lowest on record since 1979. In the Antarctic, zonally averaged sea ice extent reached an all-time record maximum from mid-June through late August and again from mid-November through early December. Corresponding record positive Southern Hemisphere Annular Mode Indices influenced the Antarctic sea ice extents. Greenland glaciers lost more mass than any other year in the decade-long record. The Greenland Ice Sheet lost a record amount of mass, as the melt rate was the highest since at least 1958, and the area and duration of the melting was greater than any year since at least 1978. High summer air temperatures and a longer melt season also caused a continued increase in the rate of ice mass loss from small glaciers and ice caps in the Canadian Arctic. Coastal sites in Alaska show continuous permafrost warming and sites in Alaska, Canada, and Russia indicate more significant warming in relatively cold permafrost than in warm permafrost in the same geographical area. With regional differences, permafrost temperatures are now up to 2°C warmer than they were 20 to 30 years ago. Preliminary data indicate there is a high probability that 2010 will be the 20th consecutive year that alpine glaciers have lost mass. Atmospheric greenhouse gas concentrations continued to rise and ozone depleting substances continued to decrease. Carbon dioxide increased by 2.60 ppm in 2010, a rate above both the 2009 and the 1980-2010 average rates. The global ocean carbon dioxide uptake for the 2009 transition period from La Niña to El Niño conditions, the most recent period for which analyzed data are available, is estimated to be similar to the long-term average. The 2010 Antarctic ozone hole was among the lowest 20% compared with other years since 1990, a result of warmer-than-average temperatures in the Antarctic stratosphere during austral winter between mid-July and early September.

14. Modelling and measurement of carbon emissions under Arctic snow

Abstract

Arctic carbon dioxide emissions during the winter months are frequently omitted from global carbon budgets, due to prior assumptions that their contribution is largely insignificant compared to other sources and seasons. This paradigm has recently been challenged, amid a growing awareness of the impact snow-ecosystem interactions have on respiration from high-latitude soils and overall carbon budgets. Through field measurements at Trail Valley Creek, NWT, Canada, and simulations using the Community Land Model 5.0, here we: consider how the representation of snow thermal conductivity in a Terrestrial Biosphere Model impacts simulated near-surface soil temperatures and net ecosystem exchange,report on new low-cost in-situ measurement techniques that aim to quantify carbon dioxide concentrations and fluxes within Arctic snowpacks.We anticipate new measurement techniques will help evaluate rates of production of carbon dioxide from frozen soils during winter months and address discrepancies between observed and simulated carbon dioxide emissions. Increased confidence in future simulations is important in a region that is highly characteristic of the high latitude critical zone, susceptible to permafrost thaw, and is warming two to three times as fast as the global average since the late twentieth century., The 28th IUGG General Assembly (IUGG2023) (Berlin 2023)

15. Impact of vegetation and climate on simulated snowpack properties along a 4000-km latitudinal transect across eastern Canada

Author

Vionnet, V., Fortin, V., Dominé, F., Royer, A., Mazzotti, G., Woolley, G., Abrahamowicz, M., Lafaysse, M., Rutter, N., Wake, L., Derksen, C., and Bélair, S.

Abstract

The current development of spaceborne missions to retrieve snow water equivalent requires state-of-the-art modelling systems able to provide accurate estimation of snowpack properties across large areas with contrasted climate and vegetation. In the context of the Terrestrial Snow Mass Mission under development at the Canadian Space Agency, the detailed snowpack model Crocus has been implemented in the Soil Vegetation and Snow (SVS) model. For each grid cell, SVS simulates the snowpack evolution (i) over ground without standing vegetation, (ii) in shrub vegetation and (iii) below trees. For each tile, the model includes the representation of the main snow/vegetation interaction processes. In this study, the ability of SVS/Crocus to simulate snowpack properties is tested along a 4000-km latitudinal transect (47°N to 83°N) in northeastern Canada covering a transition from the boreal forest to arctic ecosystems. Crocus is run at 10-km resolution along this transect over a 13-year period (2007-2019) driven by a meteorological reanalysis recently developed at Environment and Climate Change Canada. A unique dataset of detailed snowpits at multiple sites along the transect is used to evaluate the ability of the model to simulate snowpack properties (SWE, depth-hoar fraction, density and SSA profiles). Results highlight the sensitivity of model results to key physical processes (wind-induced compaction, effect of basal vegetation). Systematic errors were found in snowpack properties and may be explained by missing physical processes in the model such as water vapour fluxes. This work constitutes the first step towards the development of a new pan-Canadian snow modelling system.

16. New recommendations for snow water equivalent products: results from the international snow products intercomparison and evaluation exercise (SnowPEx+)

Author

Mudryk, L., Mortimer, C., Derksen, C., Cho, E., and Vuyovich, C.

Abstract

The SnowPEx+ initiative is a continuation of the original International Snow Products Intercomparison and Evaluation Exercise (SnowPEx), an international effort carried out under the umbrella of Global Cryosphere Watch / WMO and funded by the European Space Agency. We present the latest results concerning historical snow water equivalent products (SWE), which characterize climatological snow mass and snow mass trends.We assess a wide variety of products ranging from those based strictly on remote sensing information, blended Earth-observation products that include assimilation of ground measurements, reanalysis products of varying complexity, and snow models forced by reanalysis meteorology. We first provide a statistical assessment of product performance using two fully independent reference data sets. We demonstrate that we can robustly validate SWE product estimates in non-mountain regions where the evaluation statistics are comparable for both reference datasets. In mountainous regions, validation is complicated by systematic elevation-related biases between reference data and the assessed products, but we demonstrate that we can partially account for these biases in order to provide consistent product rankings. Secondly, we perform an intercomparison of product snow mass trends for various Northern Hemisphere subregions over the 1981-2020 period. We demonstrate good agreement among selected products. For blended Earth-observation products in particular, their agreement depends strongly on the period analyzed and is suggestive of discontinuities (related to both satellite and surface measurements) occurring during 1987 and 2008. Based on the combined validation and intercomparison results, we make recommendations for appropriate use for individual products on a case by case basis., The 28th IUGG General Assembly (IUGG2023) (Berlin 2023)

17. Exploiting optical remote sensing of tundra snow cover in evaluating climate models

Author

Essery, R., Derksen, C., Marsh, P., Nagler, T., Schwaizer, G., Tutton, R., and Walker, B.

Abstract

Seasonal snow cover extent is an essential climate variable that is, in principle, easy to measure with optical remote sensing because of the high contrast in albedo between snow and snow-free ground. In practice, however, the amount of information is severely limited by cloud cover globally and seasonal darkness at high latitudes. The European Space Agency snow cci project has now generated long-term global, daily snow cover products from AVHRR (1982-2018 at 5 km resolution) and MODIS (2000-2020 at 1 km resolution). To investigate the information content of these products and the level of uncertainty in gap filling with data assimilation for Arctic tundra snow, we take advantage of newly available in situ 1991-2022 meteorological time series for Trail Valley Creek, Northwest Territories, Canada. As a contribution to the ESM-SnowMIP project, we evaluate the ability of snow cover observations with and without gap filling to discriminate between climate model simulations submitted for CMIP6., The 28th IUGG General Assembly (IUGG2023) (Berlin 2023)

18. Winter CO2 emissions at an Arctic tundra site under bias-corrected NA-CORDEX RCP4.5 and RCP8.5 conditions

Author

Wake, L., Rutherford, J., Rutter, N., Cannon, A., Qu, B., Dutch, V., Mann, P., Derksen, C., Walker, B., Gosselin, G., Sonnentag, O., Roy, A., Voigt, C., Marsh, P., and Boike, J.

Abstract

Arctic permafrost soils are estimated to contain 1700 Gt of carbon and a warming climate signals more rapid release of CO2 from these environments, further exacerbating the warming effect of greenhouse gases. CO2 emissions from Arctic soils during the cold season were previously thought to be negligible; this is not the case and their contribution to the overall annual carbon budget is expected to increase in a warming world.Few observational and modelling studies have been directed at Arctic cold season carbon cycling processes, ultimately making any future projections of CO2 release unreliable. This unreliability is compounded by uncertainty in (1) the land component of Earth System Models regarding the parameterizations of biogeophysical and biogeochemical processes driving CO2 release during winter and (2) projections of future climate in the Arctic.Here, we use the CLM5.0 model in point mode for Trail Valley Creek near Inuvik NT, forced by ERA5 reanalysis to evaluate the performance of CLM5.0 for present-day conditions using flux tower measurements of net ecosystem CO2 exchange as model constraints. We then apply a bias-corrected NA-CORDEX ensemble of RCP4.5 and RCP8.5 scenarios to quantify the variability in future winter CO2 emissions due to (1) model uncertainty in future climate conditions and (2) parameter uncertainty in CLM5.0 relating to the temperature sensitivity of soil respiration (Q10), the moisture threshold for soil decomposition and the thermal conductivity scheme for the snow layer. The latter is a strong control on the thermal evolution of soil temperature, and therefore soil respiration during the winter., The 28th IUGG General Assembly (IUGG2023) (Berlin 2023)

The landscape freeze/thaw (FT) state has an important impact on the surface energy balance, carbon fluxes, and hydrologic processes; the timing of spring melt is linked to active layer dynamics in permafrost areas. L-band (1.4 GHz) microwave emission could allow the monitoring of surface state dynamics due to its sensitivity to the pronounced permittivity difference between frozen and thawed soil. The aim of this paper is to evaluate the performance of both Aquarius and Soil Moisture and Ocean Salinity (SMOS) L-band passive microwave measurements using a polarization ratio-based algorithm for landscape FT monitoring. Weekly L-band satellite observations are compared with a large set of reference data at 48 sites across Canada spanning three environments: tundra, boreal forest, and prairies. The reference data include in situ measurements of soil temperature (Tsoil) and air temperature (Tair), and Moderate Resolution Imaging Spectroradiometer (MODIS) land surface temperature (LST) and snow cover area (SCA) products. Results show generally good agreement between Lband FT detection and the surface state estimated from four reference datasets. The best apparent accuracies for all seasons are obtained using Tair as the reference. Aquarius radiometer 2 (incidence angle of 39.6) data gives the best accuracies (90.8), while for SMOS the best results (87.8 of accuracy) are obtained at higher incidence angles (55- 60). The FT algorithm identifies both freeze onset and end with a delay of about one week in tundra and two weeks in forest and prairies, when compared to Tair. The analysis shows a stronger FT signal at tundra sites due to the typically clean transitions between consistently frozen and thawed conditions (and vice versa) and the absence of surface vegetation. Results in the prairies were poorer because of the influence of vegetation growth in summer (which decreases the polarization ratio) and the high frequency of ephemeral thaw events during winter. Freeze onset and end maps created from the same algorithm applied to SMOS and Aquarius measurements characterize similar FT patterns over Canada. This study shows the potential of using L-band spaceborne observations for FT monitoring, but underlines some limitations due to ice crusts in the snowpack, liquid water content in snow cover during the spring freeze to thaw transition, and vegetation growth.

Abstract

Background and Purpose Although onset-to-treatment time is associated with early clinical recovery in acute ischemic stroke (AIS) patients treated with intravenous tissue plasminogen activator (tPA), the effect of the timing of tPA-induced recanalization on functional outcomes remains debatable. Methods We conducted a multicenter, prospective observational cohort study to determine whether early (within 1-hour from tPA-bolus) complete or partial recanalization assessed during 2-hour real-time transcranial Doppler monitoring is associated with improved outcomes in patients with proximal occlusions. Outcome events included dramatic clinical recovery (DCR) within 2 and 24-hours from tPA-bolus, 3-month mortality, favorable functional outcome (FFO) and functional independence (FI) defined as modified Rankin Scale (mRS) scores of 0–1 and 0–2 respectively. Results We enrolled 480 AIS patients (mean age 66±15 years, 60% men, baseline National Institutes of Health Stroke Scale score 15). Patients with early recanalization (53%) had significantly (P
