What year saw the lowest extent of sea ice on record?
2012
The animated time series below shows the annual Arctic sea ice minimum since 1979, based on satellite observations. The 2012 sea ice extent is the lowest in the satellite record.
What has happened to the extent of Arctic sea ice since 1980?
Since 1979, scientists have observed a decrease in the extent of Arctic sea ice in all months of the year. The September minimum extent is 36.5 per cent smaller in the period 2010–2019 than it was in the 1980s.
How much of Russia is above the Arctic Circle?
Approximately one-fifth of Russia’s landmass is north of the Arctic Circle.
What is the warmest the earth has ever been?
The current official highest registered air temperature on Earth is 56.7 °C (134.1 °F), recorded on 10 July 1913 at Furnace Creek Ranch, in Death Valley in the United States.
How big is the ice in the Bering Sea?
The map above shows the extent sea ice in the Bering Sea on February 16, 2022, when it covered more than 846,000 square kilometers (327,000 square miles), exceeding the 1981–2010 mean. (Ice extent is the area with at least 15 percent ice cover, the minimum at which space-based measurements give a reliable measurement.)
How big was the Arctic sea ice in September 2019?
Arctic sea ice extent for September 2019 was 4.32 million square kilometers (1.67 million square miles). The magenta line shows the 1981 to 2010 average extent for that month. Sea Ice Index data. About the data Credit: National Snow and Ice Data Center High-resolution image Figure 1b.
Is the sea ice index increasing or decreasing?
Sea Ice Index data. Since the Antarctic maximum sea ice extent was reached on September 1, 2021, ice extent has been in a steep decline. Extent went from being above the interdecile (ninetieth percentile) range to being below the tenth percentile for most of October.
What’s happening to sea ice?
In the Arctic, where annual average temperatures have increased more than three times as fast as the global average, the sea ice extent is declining. This is true especially in summer, but also year-round, in nearly every region—except the Bering Sea, said Walt Meier, a sea ice researcher at the National Snow and Ice Data Center (NSIDC).
