Annual 2021 National Climate Report
The increase in annual temperatures has not been linear, which means that there has not been a continuous increase in temperature over the past 70 years. There is a basic variation from year to year, but there are also some temperature "shifts" that can be seen when looking at the long record. In the late 1970s, there was a well-documented increase in temperature across the state corresponding to a warm change in sea surface temperature. A later shift occurred in 2014, which was also linked to warmer ocean temperatures and less sea ice off the west coast of Alaska. After 2014, Alaska had six consecutive warmer-than-normal years, including the warmest year on record in 2019 and the second warmest year on record in 2016. All climate stations in the Parks recorded Arctic change in 2014, along with a corresponding change. increase in ground temperature measured at those locations (see How we monitor). Rising ground temperatures in the Arctic mean that the frozen ground (permafrost) can begin to melt, causing numerous ecological changes to the landscape. In 2020, the climate pattern has changed. 2020 and 2021 were significantly cooler than the previous six years, but still in the near-normal range (below).
Average annual temperatures (1950–2021) from Bettles, Kotzebue, and Nome near the Arctic National Parks. The dashed black line shows the trend over time and the red lines show the average temperature before and after the 1976 and 2014 temperature changes.
Sea ice affects temperature and precipitation in arctic fields. The ice-free ocean provides available moisture for rain and snow, while the dark water absorbs solar radiation and warms the land nearby. The white ice layer reflects heat back into the atmosphere and locks in available moisture.
Rain and Snow The amount of annual precipitation and snow is much more variable and less spatially coherent than temperature, but all Arctic Parks have become wetter over the past 70 years. The seasonality of this increase, whether it falls as snow in winter or rain in summer, is ecologically important in arctic fields. Data from Kotzebue and Nome near the parks in northwest Alaska show a significant increase in winter snowfall or "cold" season (October-April) precipitation. At Bettles, near Gates of the Arctic NP&P, precipitation increased significantly in the warm and cool seasons, although the trend is stronger for the warm season (May–September).
The Weather And Climate In Iceland
In the Bettles, total annual rainfall has increased by 114 mm over the last 70 years. Warm season rainfall, summer rainfall as well as low season rainfall in May and September increased by 76 mm over this period. Cold season precipitation increased by 38 mm, a good indicator of seasonal snow cover. On average, Bettles receives 371 mm of rain per year. Summer precipitation accounts for 42% of the annual total.
In Kotzebue, annual rainfall has increased by 105 mm since 1950. Almost all of this increase has occurred during the cold months of the season, with a significant increase of 96 mm over the past 72 years. On the contrary, there was only the increase in the warm season
8 mm, no trend. Kotzebue has relatively low annual precipitation and, like most Alaskan communities, the rainy season is during the summer. Precipitation in June, July and August accounts for more than half of the total precipitation total.
Nome is also wetter in the cold season. In Nome, there was a significant increase in precipitation totals for October, December and February. There is no trend in warm season precipitation, and summer precipitation totals have not increased over the past 70 years. The total annual rainfall for Nome is 415 mm, about 60% of which falls during the warm season between May and September, with August being the wettest month of the year.

Why Climate Matters Climate is the most important large-scale factor affecting ecosystems. Because global climate models suggest that climate change and diversity will be greatest at high latitudes, climate data from these northern parks will help us understand the changing conditions of park ecosystems. Monitoring is critical to understanding the impact of changes in warming and precipitation on park ecosystems, resources and communities now and in the future. Possible consequences in Arctic fields include reduced snowpack, earlier ice breakup on lakes, warmer winters and wetter summers. These changes can affect the distribution, abundance, growth and productivity of plants and animals. What we want to know about vital signs
Location of Arctic Network climate stations in Arctic National Parks. Bering Land Bridge National Preserve (BELA), Cape Krusenstern National Monument (CAKR), Noatak National Preserve (NOAT), Kobuk Valley National Park (KOVA), and Gateway to the Arctic National Park and Preserve (GAAR).
How We Monitor Climate The Arctic Network has 21 climate stations (17 Arctic Network Remote Weather Stations [RAWS], 3 Fire RAWS, and 1 Snotel [an automated data collection network that provides hydroclimate data from mountain regions in the western US] ). fields that continuously record temperature, summer precipitation, wind speed and direction, soil temperature, relative humidity, and solar radiation. Snow depth is measured at some of the more sheltered locations. Many of these locations are located in exposed windy locations where accurate snow measurements are difficult. These rare high-latitude weather stations, as well as stations in nearby communities (Nome, Kotzebue, and Bettles), provide critical quantitative data for current and future research and management decisions.
How climate monitoring can help park managers Climate monitoring is critical to understanding the changing conditions of park ecosystems. The consequences of our warming climate on Alaska's park resources can be dramatic in the form of melting glaciers and permafrost, more frequent fires, and changes in vegetation. Data and information collected from Alaska's parks provide an important piece of the puzzle in understanding the causes and impacts of climate change at local and regional (even global) levels.

Sunshine In Anchorage, the average is 7.6 hours of sunshine in September. UV Index The average daily maximum UV index in September in Anchorage is 2. A UV index estimate of 2 and below indicates a low health risk to the general public from hazardous UV exposure.
Climate Change Transforming Arctic Into Warmer, Wetter Region
Long exposure to the sun is not a problem for most. Children, infants and fair-skinned people must always be protected. The most intense and therefore most harmful UV radiation from the Sun during daytime hours should be reduced by minimizing exposure and seeking shade. On clear days, you should wear sunglasses that block both UVA and UVB rays. A wide-brimmed hat is very useful because it can prevent about 50% of UV rays from reaching the eyes. Attention! The reflection of snow can almost double the intensity of the sun's UV radiation.
