When scientists talk about the cryosphere, they mean the places on Earth where water is in its solid form, frozen into ice or snow. Read about the data and other problems which occasionally occur in near-real-time data. The 10-year average line includes estimates from before 1978 on the left edge of the graph.Credit: X. Fettweis, Université of Liège, Belgium/MARv3.11 regional climate modelHigh-resolution image. This can be compared to the major melt and ice loss years of 2012, 2019, and others in the last decade with values between 225 and 325 billion tons below average (Figure 5b). Based on weather reports collected during 1985–2015. To pry climate clues out of the ice, scientists began to drill long cores out of the ice sheets in Greenland and Antarctica in the late 1960s. The Greenland melt images here are updated daily, with a one-day lag. Credit: Programme for Monitoring of the Greenland Ice Sheet (PROMICE) High-resolution image. The total aerial extent of surface melting (total melt-day extent) through October 31 is slightly above the 1981 to 2010 average at 23.10 million square kilometers (8.92 million square miles) for 2020 versus 22.00 million square kilometers (8.49 million square miles) for the 1981 to 2010 average. Access hourly, 10 day and 15 day forecasts along with up to the minute reports and videos from AccuWeather.com Greenland Climate Greenland has two different climates and is dominated by ET. Interactive Map Select study locations by region, proximity to a point, or text-based attributes. Learn about update delays. Data for the diffusion of the water molecules in the individual annual layers in the Greenland ice cores has thus made it possible to calculate the temperature in the layers with compressed snow 19,000 years back in … Greenland Ice Sheet Today is produced at the National Snow and Ice Data Center by Ted Scambos, Julienne Stroeve, and Lora Koenig with support from NASA. 14-08 presents weatherdata for Greenland from 1958 to 2013. Long temperature series shows a clear trend: We’re getting warmer. We are working to improve the ice sheet mask. Responses include narrowing of fast flow regions, rerouting of ice flow, and abandonment of some glacier outlets. Scientists blog from Antarctica and provide a glimpse of what it's like to do research in the field. Dr. Jason Box, Geological Survey of Denmark and Greenland (GEUS), Greenland melt season model simulations We post analysis periodically as conditions warrant. Tedesco, M. and X. Fettweis. Melt extent was greater than any year prior to 2002, with about 70 percent of the ice sheet experiencing some melting. Greenland Surface Melt Interactive Extent Chart, Greenland melt data spreadsheets, and more tools for Greenland melt analysis. There were two later melt events of note, on August 20 when extensive areas in northwestern Greenland melted totaling just over 20 percent of the ice sheet, and a late event on October 17, limited to the southwestern ice sheet totaling under 3 percent of the ice. It is very cold all year long. Due to Gulf Stream influences, Greenland's winter temperatures are very mild for its latitude. Nuuk, the capital of Greenland on the central southwestern coast, had summer temperatures very close to average for that region. The Climate Change Knowledge Portal is a hub of information, data and reports about climate change around the world. Mote, University of Georgia High-resolution image, Figure 2. Polar Portal: Monitoring ice and climate in the Arctic The peak melt day for 2020 was on July 10, when 551,000 square kilometers (213,000 square miles), or 34 percent of the ice sheet surface, melted. Cumulative degree days (the sum of the difference between the freezing point, 0 degrees Celsius, and the maximum temperature each day for the spring-summer melt season for two automatic weather stations in Greenland, at Nuuk (NUK_L) and Thule (THU_L). Figure 6. Greenland’s 2020 summer melting: a new normal? While thinning ice and retreats from the ice edge change the ice sheet, the shape of the land beneath the ice remains mostly unchanged. Researchers also see evidence for ice flow rerouting and even abandonment of some glacier outlets. Moon, T. A., A. S. Gardner, B. Csatho, I. Parmuzin, and M. A. Fahnestock.

Greenland - Climate data - Climate information and average monthly temperature, humidity, rainfall, snowfall, daylight, sunshine, UV index, and sea temperature for all cities and towns. The 2020 Greenland Ice Sheet SMB simulated by MARv3.5.2 in real time, Polar Portal’s Greenland surface conditions, Programme for Monitoring of the Greenland Ice Sheet (PROMICE), Jason Box, Geological Survey of Denmark and Greenland (GEUS) in Copenhagen, Denmark, Xavier Fettweis, Université of Liège in Belgium, providing the MARv3.11 model results, Twila Moon, National Snow and Ice Data Center. 2020.  Climate is the statistics of weather, usually over a 30-year interval. Learn how the World Bank Group is helping countries with COVID-19 (coronavirus). In Greenland, an autonomous territory of the Kingdom of Denmark, the climate is arctic along the north-central coasts (zone 1 on the map), where the temperatures of the warmest months are around freezing (0 °C or 32 °F) and subarctic on the south-central coasts (zone 2 on the map), where the average temperatures in the summer months are above freezing, but still below 10 °C (50 °F). What both of these temperature curves show is that virtually all of the past 10,000 years has been warmer than the present. Annual Weather Averages in Thule Air Base. Home | Contact Us In Nuuk, the average daily temperature varies over the seasons from −5.1 to 9.9 °C (23 to 50 °F) The total area of Greenland is 2,166,086 km 2 (836,330 sq mi) (including other offshore minor islands), of which the Greenland ice sheet covers 1,755,637 km 2 (677,855 sq mi) (81%) and has a volume of approximately 2,850,000 km 3 (680,000 cu mi). 14-07 is a guide on how to read and use of the climate data. By Dr. Xavier Fettweis, University of Liège. The thickness of the ice is approximately 1500 meters (59 055 inch). The new results show that during the Eemian period 130,000 to 115,000 years ago the climate in Greenland was around 8 degrees C warmer than today. A look at weather station data along Greenland’s west coast reflects the regional temperature trends (Figure 4). Air temperatures above Greenland were generally near average over the summer months this year (Figure 3).
