JAKARTA – The latest data reveals temperature Greenland continues to increase, even to be hottest in 1,000 years this. Experts fear a catastrophe will occur in 2050.
New data has revealed that temperature Of Greenland is the hottest in 1,000 yearsunderscoring the growing impact of human-driven climate change on nature.
A study published in the scientific journal Nature on Wednesday (18/1/2023) found that temperature has increased 1.5 degrees Celsius (2.7 degrees Fahrenheit) over the 20th century average since 1995.
The data shows that the ice core Greenland – samples taken from deep ice sheets and glaciers – have warmed substantially.
“We continue to (see) improvement temperature between the 1990s and 2011,” said the study’s lead author Maria Hoerhold, a glaciologist at the Alfred Wegener Institute in Germany.
“We now have a clear sign of global warming.”
As consumption of fossil fuels releases carbon into the atmosphere and warms the planet, scientists have warned that governments have not made the necessary changes to prevent the worst effects of global warming.
In November, a United Nations report found that many of the world’s most famous glaciers could disappear by 2050 as the planet warms.
Of the more than 18,600 glaciers the organization monitors across 50 World Heritage Sites, about a third are expected to disappear by the middle of this century.
Another study found that two-thirds of the world’s glaciers are expected to disappear by 2100.

The data from the last core was updated in 1995 and previously showed that Greenland not warming as quickly as the rest of the Arctic.
However, the newly analyzed cores, taken in 2011, show a sharp increase over the past 15 years.
“This is an important finding and reinforces the suspicion that the ‘lost warming’ in the ice cores is due to the fact that the ice cores expire before intense warming occurs,” said climate scientist Martin Stendel of the Danish Meteorological Institute who was not involved in the study.
Hoerhold said that natural weather variability and undulations caused by occasional weather systems called “Blocks Greenland” previously hid the toll of human-caused climate change.
But in the 1990s, the changes became too big to ignore.
Past data shows warming Greenland at a lower rate than the rest of the Arctic, which is warming four times faster than the global average.
Now, Greenland seems to be catching up.
Ice cores are used to create forecast charts temperature Of Greenland for a period of more than 1,000 yearsfrom 1000 to 2011.
During the first 800 years, temperature slowly cooled, then fluctuated before a dramatic surge in the 1990s.
Hoerhold said that there was “almost zero” chance that the post-1995 spike was caused by factors other than climate change.
Another set of ice cores was retrieved in 2019, but Hoerhold says it’s still being studied.
The study also revealed that more water is released when it is ice Greenland melting, contributing to rising sea levels.
“We should be very concerned about warming Greenland North,” said Danish Meteorological Institute ice scientist Jason Box.
“Because that region has a dozen sleeping giants in the form of vast tidal glaciers and ice flows.”
