Arctic has warmed three times faster than Earth since 1971: report

OSLO: The Arctic warmed three times faster than the entire planet between 1971 and 2019, a higher rate than before, a scientific report warned on Thursday.
There is a big difference in each degree of one degree: the probability of snow disappearing completely in summer – before freezing again in winter – is 10 times higher if the Earth’s temperature rises by 2 degrees Celsius if it is 1.5 Goals have been set if the degree Celsius rises. By the Paris Agreement.
The shocking data is part of a report by the Arctic Monitoring and Assessment Program (AMAP), which is published this week with a ministerial meeting of the Arctic Council in Reykjavik gathering countries bordering the region.
“An important update is that the increase in Arctic annual average surface temperature (land and ocean) between 1971 and 2019 was three times higher than the increase in the global average over the same period. This compared to the report in the previous AMAP assessment More, ”the report’s authors said.
A previous update, in 2019, stated the annual average warming in the Arctic was “more than double the global average, with higher increases in winter”.
According to the updated report, in less than half a century, from 1971 to 2019, the average annual temperature of the Arctic increased 3.1 ° C compared to 1 ° C for the entire planet.
The report states, “Under most (greenhouse gas) emission scenarios … the models offer the first example of a large-scale sea-ice-free Arctic to occur before 2050 in September.”
September is usually the month with the lowest sea ice.
“The probability of an ice-free Arctic summer is 10 times higher under a 2 ° C global warming scenario than under a 1.5 ° C scenario,” the researchers said.
According to the forecasts cited in the report, by the end of the century the average temperature in the Arctic is expected to rise between 3.3 and 10 degrees above the 1985–2014 period average, the final figure based on future greenhouse gas emissions.
