Snow cover stats for last month are also shown. Trend lines have been added. Reconstructed historical estimates are used to extend the time series back to 1922. Snow cover extent in the Northern Hemisphere has declined significantly over the past 90 years, with most of the reductions occurring since 1980.

The second important influence on both snow cover and land surface temperature is elevation. This web portal provides information on all adaptation activities of the European Commission. It also looks at society’s vulnerability to these impacts and at the development of adaptation policies and the underlying knowledge base. Snow influences the climate and climate-related systems because of its high reflectivity, insulating properties, effects on water resources and ecosystems, and cooling of the atmosphere. Snow influences how hot or cold the land feels to the touch, and it can chill the air that sits next to the surface. of this website is provided through the National Oceanic Land surface temperature influences whether or not snow remains on the ground or melts away. It differs from air temperature (the temperature given in weather reports) because land heats and cools more quickly than air. Knowledge Basis for Climate Change Adaptation Updated in 2015) [in Norwegian]. Snow cover stats for last month are also shown. 2012: Final Report. Specific regional studies suggest significant reductions in snow mass in, for example, the Alps in general [viii], Switzerland [ix], the alpine range of Italy [x], the Pyrenees [xi], Norway [xii], the Turkish mountains [xiii] and the Balkan mountains [xiv].

Snow mass in the Northern Hemisphere is estimated to have decreased by 7 % in March from 1982 to 2009; snow mass in Europe has decreased more rapidly than the average for the Northern Hemisphere, but with large interannual variation. Snow cover, 19 Nov 2012 - Climate-ADAPT has been developed jointly by the EC and the EEA to share knowledge on (1) observed and projected climate change and its impacts on environmental and social systems and on human health, (2) relevant research, (3) EU, transnational, national and subnational adaptation strategies and plans, and (4) adaptation case studies.

The cryosphere which are areas covered by ice, snow, glaciers, or permafrost is an extremely dynamic part of our global system. The most obvious connection between land surface temperature and snow cover is the way they both change with the seasons. The strategy aims to make Europe more climate-resilient. In November 2013, the European Parliament and the European Council adopted the 7th EU Environment Action Programme (7th EAP) to 2020, ‘Living well, within the limits of our planet’. 6 (March 2015): 2136–53, doi:10.1175/JCLI-D-14-00558.1. World Wide Daily Snow and Ice Cover Map. Projcted changes in snow cover extent up to 2100 are available from the CMIP5 ensemble of climate models for different climate forcing scenarios (RCPs). In April 2013, the European Commission adopted an EU strategy on adaptation to climate change, which has been welcomed by the EU Member States. RUGSL (2011) Fall, Winter, and Spring Northern Hemisphere Snow Cover Extent. Despite the projected decrease in long-term mean snow mass in the Northern Hemisphere, model simulations indicate occasional winters of heavy snowfall, but these become increasingly uncommon towards the end of the 21st century. 46 (2016): 339–53, doi:10.1007/s00382-015-2587-0. ‘In 2050, we live well, within the planet’s ecological limits. Over the period 1967–2015, snow cover extent in the Northern Hemisphere has decreased by 7 % on average in March and April and by 47 % in June; the observed reductions in Europe are even larger, at 13 % for March and April and 76 % for June. 1 (18 June 2015): 137–42, doi:10.5194/essd-7-137-2015. Trend in snow cover extent over the Northern Hemisphere and in Europe, Trend in March snow mass in Europe (excluding mountain areas), Projected change in Northern hemisphere spring snow cover extent. ranks as the 17th least extensive cover EEA Plone KGS 20.10.13. Heat we can send you a new one. The multi-model mean from the CMIP5 modelling exercise projects changes in March/April snow cover extent in the Northern Hemisphere during the 21st century ranging from 7 % for a low emissions scenario (RCP2.6) to 25 % for a high emissions scenario (RCP8.5) (Figure 3). [click for more information]. This report is an indicator-based assessment of past and projected climate change and its impacts on ecosystems and society.
It highlights that ‘Action to mitigate and adapt to climate change will increase the resilience of the Union’s economy and society, while stimulating innovation and protecting the Union’s natural resources.’ Consequently, several priority objectives of the 7th EAP refer to climate change adaptation. Snow cover extent in the Northern Hemisphere has declined significantly over the past 90 years, with most of the reductions occurring since 1980. The warmest temperatures are pale yellow, while the coldest temperatures are dark blue. Daily image maps show the extent of snow and ice over the contiguous United States, Alaska, or the whole Northern Hemisphere. This website has limited functionality with javascript off.

[v] Vaughan et al., ‘Observations: Cryosphere’. Gray indicates land areas with no snow, darkest blue represents minimal snow cover, and solid white indicates 100 percent snow cover. We also include other data, such as the SWE (snow-water equivalent). Changes in seasons & climate bring great changes to the Earth's cryosphere. GlobSnow. Adaptation means anticipating the adverse effects of climate change and taking appropriate action to prevent or minimise the damage they can cause, or taking advantage of opportunities that may arise. Support for the development and maintenance Satellite observations of monthly snow cover extent in the Northern Hemisphere are available from 1967 onwards [i].

This edition aims to support the implementation and review process of the 2013 EU Adaptation Strategy, which is foreseen for 2018, and the development of national and transnational adaptation strategies and plans.
If you have forgotten your password, Satellite observations on the monthly snow cover extent in the Northern Hemisphere are available since November 1966 from the Rutgers University Global Snow Lab. (2013): An analysis of present and future seasonal Northern Hemisphere land snow cover simulated by CMIP5 coupled climate models. Snow cover values range from medium blue (greater than 0 percent) to white (100 percent). As air temperatures warm, snow begins to melt, and the exposed darker ground can cause a positive feedback to the melting process by absorbing more of the Sun's warmth.
3 (September 2011): 113–23, doi:10.1016/j.coldregions.2011.06.011. To a lesser degree, the same is true of the Andes Mountains in South America. Snow cover extent in the Northern Hemisphere has declined significantly over the past 90 years, with most of the reductions occurring since 1980.

Technical. Model simulations project widespread reductions in the extent and duration of snow cover in the Northern Hemisphere and in Europe over the 21st century. Northern Hemisphere snow cover will continue to shrink and snow seasons shorten as temperatures rise [v], although in the coldest regions snowfall can also increase in the middle of winter [vi].
