Arctic and Antarctic weekly sea ice extent from the US National Snow and … The study describes the ongoing climate change in the Arctic and its consequences: rising temperatures, loss of sea ice, unprecedented melting of the Greenland ice sheet, and many impacts on ecosystems, … Mark Serreze said “We’re heading for summers with no sea ice coverage at all.”. The average annual land surface air temperature north of 60° N for October 2019-September 2020 was the second highest on record since at least 1900. Every summer the Arctic ice cap melts down to what scientists call its "minimum" before colder weather begins to cause ice cover to increase. Red bars represent global temperature anomalies in El Niño years, with the red line showing the trend. Updated 11/1/2020. weather action zoom earth quake sheet. The tally in 2020 was a meagre 3.74 million square kilometres, the second-smallest measurement in 42 years, and roughly half of what it was in 1980.Each year, as the climate warms, the Arctic is holding onto less and less ice. This graph shows the annual Arctic sea ice minimum each September since 1979, derived from … Retrospective or Historical Data, Analyses and Indices Data and Analyses. It was the 11th-lowest maximum in the 42-year satellite record. Arctic Data Sets from the Polar Science Center at University of Washington/Applied Physics Laboratory ; Historical data from the First International Polar Year, 1881-1884 from NOAA ; Freshwater Switchyard of the Arctic Ocean - from the University of Washington Polar Science Center Every year, usually in September, the sea ice cover shrinks to its lowest level. This unambiguously exceeds the previous record of 1.88 °C observed in 2016. Antarctic monthly temperature change south of 50S. Annual surface air temperatures over the last 4 years (2016–2019) in the Arctic (60°–85°N) have been the highest in the time series of observations for 1936-2019. According to IPCC Sixth Assessment Report, in the last 170 years, humans increase the global temperature to the highest level in the last 2,000 years.Multi-century period warmer than the current period occurred more than 100,000 years ago. Record warm surface temperatures. The Arctic Weather Map below shows the weather forecast for the next 12 days. Though nowhere near a record low, it was well below the 1981–2010 average. This makes 2020 the second warmest year for the region since at least 1979; 0.5°C below the record of 2016. Surface air temperature operational data, 1985-1996 baseline. On the right side are the Euro-Russian seas already frozen over end of October. It is nearly always warmer in daylight than at night time. The graph above shows Arctic sea ice extent as of October 5, 2021, along with daily ice extent data for four previous years and the record low year. Temperature hovers around 23°c and at night it feels like 14°c. What puzzles me Tony is this: why is the volume of ocean ice in 2020 not higher compared to 2017, 2018, and 2019? Temperature change in the last 2,000 years. The concept of an average temperature for the entire globe may seem odd. In 2020, the Arctic minimum sea ice covered an area of 3.36 million square kilometers. Levels Graph. There is a large amount of variability in climate across the Arctic, but all regions experience extremes of solar radiation in both summer and winter. Temperature 1-day anomaly reanalysis data, 1981-2010 baseline. Arctic sea ice extent reached its apparent annual maximum on March 5, 2020. This sea ice grows dramatically each winter, usually reaching its maximum in March. After all, at this very moment, The graph above and data below are the average monthly temperatures. Other studies suggest that increased nutrient supply have also influenced overall production (Henley et al. Chart: NSDIC. Average January temperatures range from about −34 °C to 0 °C (−29 to +32 °F), and winter temperatures can drop below −50 °C (−58 °F) over large parts of the Arctic. Average July temperatures range from about −10 to +10 °C (14 to 50 °F), with some land areas occasionally exceeding 30 °C (86 °F) in summer. The DMI plotting model, seen here, comprises the “daily mean temperature and climate north of the 80th northern parallel, as a function of the day of year.”Note that this year, the temperature rise got off to a late start. Open the word processing document in which you pasted the Sea Ice Extent graph and paste your November Temperatures graph next to it. 3. Yearly minimum extents (2002-2020) are shown by the scatter points with color in reference to the magnitude. As discussed below, many territories saw record warm annual averages in 2020, with conditions in Northern Asia being particularly extreme. Climate Change Indicators: Arctic Sea Ice. 1).

Can you imagine the likes of The Guardian, for example, ever running with this? Temperature 7-day anomaly reanalysis … Sea surface temperature increased during the 20 th century and continues to rise. An analysis of satellite data by NASA and the National Snow and Ice Data Center (NSIDC) at the University of Colorado Boulder shows that the 2020 minimum extent, which was likely reached on Sept. 15, measured 1.44 million square miles … It melts just as dramatically each summer, reaching its minimum in September. Figure 2a. Individual years from 1958-2020 are shown by the sequential blue/purple to yellow lines. These are good for comparison purposes but a bit misleading when imagining what the climate in a location is like. The temperature in the years 2011-2020 was 1.09°C higher than in 1859-1890. The hidden crisis of 2020: Graph reveals 'brutal' climate event. From 1901 through 2020, temperature rose at an average rate of 0.14°F per decade (see Figure 1). Paleoclimate data indicate there was less Arctic sea ice during the pre-industrial period than in modern times, or when CO2 concentrations were 100 ppm lower than today (280 vs. 380 ppm). The seasonal sea ice melt cycle is driven by seasonal temperature changes. Retrieved from Climate Reanalyzer, developed by the Climate Change Institute at the University of Maine to provide an intuitive platform for visualizing a variety of weather and climate datasets and models. The Arctic's climate is characterized by cold winters and cool summers. Its precipitation mostly comes in the form of snow and is low, with most of the area receiving less than 50 cm (20 in). Despite its unusually high temperatures during the first three months, 2020 is still running behind 2016 in terms of year-to-date (Q1) temperatures. Calculation of the Arctic Mean Temperature. Describe the relationship you see between the 2 datasets. Arctic ice. Only January 2016 was warmer, at +4.3°C. ERA40 has been applied for the 1958-2002 climatology (white line), while the operational ECMWF is used for the current year. The daily mean temperature of the Arctic area north of the 80th northern parallel is estimated from the average of the 00z and 12z analysis for all model grid points inside that area. Figure 1. 2020 produced frightening signs of the precariousness of Arctic sea ice. 1990-1991. The first graph tracks the change in sea level since 1993 as observed by satellites. be seen! Retrospective or Historical Data, Analyses and Indices Data and Analyses. Latest daily Arctic sea ice extent (JAXA AMSR2) for 2020. Since 1979, satellites have monitored sea ice growth and retreat, and they have detected an overall decline in Arctic sea ice. This graph features atmospheric CO2 levels that combine measurements from as far back as 800,000 years up to the present day with an atmospheric temperature overlay option. However the two most widely used definitions in the context of climate are the area north of the northern tree line, and the area in which As discussed in an earlier post, a 2020 El Niño could be the catalyst to trigger feedbacks, including huge methane releases from the Arctic Ocean seafloor. Researchers from more than 100 universities, government agencies and conservation groups across 17 countries are involved in the archive, which is hosted by the Max Planck Institute . And this is NASA’s current graph, which now shows a strong warming trend during that period. Chart by Carbon Brief using Highcharts.. Both 2012 and 2020 were extraordinary when compared to the 30 year average from 1981-2010. 2020 Arctic air temperatures continue a long-term warming streak. As the image shows, the January 2020 anomaly is well above the blue trend. Layers of frozen seawater cap the Arctic Ocean. Carbon dioxide (CO 2) is an important heat-trapping (greenhouse) gas, which is released through human activities such as deforestation and burning fossil fuels, as well as natural processes such as respiration and volcanic eruptions.The first graph shows atmospheric CO 2 levels measured at Mauna Loa Observatory, Hawaii, in recent years, with the average … "What happens in the Arctic does not stay in the Arctic. The 1981 to 2010 median is in dark gray.
This is a free service, but we do ask for a donation if you find this useful. I personally like maps to get a spatial awareness of changes in ice extent, but this can be expressed in graph form too. The 2020 annual surface air temperature averaged over the whole Arctic was 2.2°C above the 1981‒2010 average, according to the C3S ERA5 dataset. We have a larger sea ice extent in 2020 compared to those years, and temperatures in the fall preceding the winter being lower. Weather in Arctic in June. Temperatures in the Arctic Circle are likely to have hit an all-time record on Saturday, reaching a scorching 38C (100F) in Verkhoyansk, a Siberian town.

Sea surface temperature has been consistently higher during the past three decades than at any other time since reliable observations began in 1880 (see Figure 1). Record warm temperatures in the Eurasian Arctic were associated with extreme conditions in the ocean and on the land. Humidity is close to 78%. The year 2020 follows the trend of the past decades and its spring months were the absolutely warmest since measurements started more than 100 years ago, a weather report from Russian meteorological service Roshydromet … These are the three areas that are most requested. The chart below shows the average Arctic sea ice extent for each week of the year for every year between 1978 and 2020, with 2020 to-date highlighted with a thick black line. September Arctic sea ice is now declining at a rate of 13% per decade, relative to the 1981 to 2010 average.
Sea level rise is caused primarily by two factors related to global warming: the added water from melting ice sheets and glaciers and the expansion of seawater as it warms. Blue bars depict La Niña years, and the blue line shows that trend. However, it is still not as big and strong as the Antarctica ozone hole due to cooler temperatures in the south and the presence of aerosols.
Sea Ice Same Thickness As 60 Years Ago. Between 1979 and 2015, the average monthly extent for September declined by 13.4 percent per decade. and unusually large ozone hole over Arctic Mean sea ice extents from the 1980s, 1990s, 2000s, and 2010s are also shown by the dashed lines. Every summer the Arctic ice cap melts down to what scientists call its "minimum" before colder weather begins to cause ice cover to increase. The first graph tracks the change in sea level since 1993 as observed by satellites. … Temperature Bad News Alarmists - Official Data Reveals Arctic Sea Ice ...
