Climate change in the Arctic disrupts computer algorithms

Climate change in the Arctic disrupts computer algorithms

But it turned out that not a station came out of operation, but only changes in the climate.

Since 1979, when the first-year sea ice began to monitor the satellite, the average temperature in Utqiagvik from January to September rose by 1.9 degrees Fahrenheit. This is two times higher than in the lower 48 states of America.

Scientists from the National Oceanic and Atmospheric Administration (NOAA) said that climatic changes in the Northern Arctic are much faster than in other regions. Therefore, they are forced to rewrite the data correction algorithms, which purify the received observations from the emissions.

In Alaska, 514 km north of the Arctic Circle, there is a weather station in the most northern city of America - Utqiagvik (formerly Barrow), which collects temperature data since the 1920s.

In preparation for the US climate report this month, experts noted that they did not have enough data from Utqiagvik for 2017 and part of 2016. It turned out that the recorded temperature during this period was significantly higher than ever before. The data was so much above that the embedded algorithm, established to remove inconsistencies, marked the temperature data as unrealistic and excluded them from the report.

Scientists explained that the exact location of the weather station, temperature recording equipment, and necessary procedures were sometimes changed, which led to emissions in the data. Therefore, an algorithm was developed that filters noise. Also,  the temperature in the region is growing because of the shrinking of the Arctic ice volume, and this leads to a vicious cycle, from high temperatures to ice loss and again to a rise in temperature and even more significant ice loss, the weather station in Utqiagvik decided that something broke.

During the last 17 years, the average temperature in October, November and December increased sharply with a difference of 7.8, 6.9 and 4.7 degrees Fahrenheit respectively.
"The current rate of decline in sea ice and warming is significantly higher than at any other time in the past 1500 years, and probably even longer," the NOAA report says.

"  All the people of good will can take an active part in changing the current situation by changing the ideology of the world society from the consumer format of thinking to the spiritual and creative format, to the assertion in society of priorities of mutual help, friendship, and spiritual and moral relationships between people not in words but in deeds. People must cast away all the boundaries and conventions; they need to become consolidated here and now. Nature does not look at titles and ranks when it unleashes its millennial anger, and only a manifestation of true brotherhood between people based on human kindness can give humanity a chance for survival ".  ( From the report of the international community ALLATRA SCIENCE" On the Problems and Consequences of Global Climate Change on Earth. Effective Ways to Solve These Problems")
