New study finds Greenland hottest in 1,000 years

on 19 Jan 2023 Al Jazeera website Report a new study by a team of scientists who study glaciers. shows that Greenland’s Ice Core The northernmost land in the world in the arctic ocean It is currently experiencing its hottest temperature in 1,000 years, a ‘clear signature’ of human-caused global warming.

The new study took samples from Greenland’s deep ice sheets and glaciers. which is the largest island in the world It has an area of ​​regarding 2.17 million square kilometers. Published in the scientific journal Nature on Wednesday, January 18, the temperature of Greenland’s ice cores has risen by 1.5 degrees Celsius from the 20th-century average since 2007. 1995

‘We’re looking at rising temperatures between the 1990s and 2011,’ said study lead author Maria Hoerhold. ‘We have a clear signature of glaciation.global warming’

In November 2022, a United Nations report released that many of the world’s most famous glaciers might disappear by 2050 as the world warms. According to UN scientists tracking the situation of more than 18,600 glaciers in 50 World Heritage Sites, it is estimated that regarding one-third of these glaciers are glaciers. will disappear by the middle of this century. Another study estimates that two-thirds of the world’s glaciers will disappear by 2100, with the melting of Greenland’s glaciers likely to increase sea levels.

The report states that ice cores in Greenland can reveal information regarding long-term temperature changes which takes time to analyze Data from Greenland’s ice cores were last analyzed in 1995. Previously, it had indicated that Greenland’s temperatures were not warming as quickly as other regions. of the Arctic Ocean

However, a new study of the Greenland ice cores A study conducted in 2011 showed that ice cores have warmed significantly over the past 15 years, while scientists have taken the ice cores to chart the average temperature in Greenland over the 1,000 range. Years from the year 1000 until the year 2011.
