January 2020 is the hottest January on record

January was the hottest January on record, again highlighting the overall trend of climate change on Earth and raising concerns about declining sea ice cover, according tomedia Slash Gear. The study, published by scientists at the National Oceanic and Atmospheric Administration’s (NOAA) National Environmental Information Center, found that January 2020 was the 421st consecutive month to be higher than the average for the same month of the 20th century.

January 2020 is the hottest January on record

In fact, from NOAA’s 141-year record, the global surface temperature on land and sea in January 2020 was 2.05 degrees Fahrenheit higher than the average for the same month of the 20th century. The last time a record temperature was recorded was in January 2016. “The four hottest Januarys on record since 2016 and the 10 hottest Januarys since 2002 have been recorded,” NOAA said. “

NOAA observed not only unusually warm weather. For example, in most parts of Alaska and parts of western Canada, temperatures are at least 7.2 degrees Fahrenheit below average. In terms of average rainfall, Alaska’s January was also the driest since 2006 and the 14th driest on record.

This is different from much of the U.S., where most u.S. states receive above-average rainfall in January. The average rainfall was 2.7 inches, 0.39 inches more than usual, making the month one of the wettest Januarys on record. NOAA said the average rainfall was 4.99 inches over the 12 months from February 2019 to January 2020, the third wettest period on record.

Sea ice and climate change remain a huge problem

One of the most obvious aspects of climate change is Arctic sea ice. By January 2020, the measured area will be 5.27 million square miles. NOAA researchers point out that it is 297,000 square miles less than the 1981-2020 average. In addition, Antarctic sea ice is also below average, 9.8 per cent below the 1981-2020 average. It reached 1.74 million square miles. In addition, snow cover in the northern hemisphere hit a low in January, the 18th low in the same period in the past 54 years.

NASA recently marked observations that the Bovert vortex, the main arctic ocean current, is becoming increasingly turbulent as Arctic sea ice melts rapidly. It plays a huge role in polar balance, keeping fresh water free from melting glaciers, river runoff and general precipitation cycles around the western Arctic Ocean, northern Canada and Alaska, and helping to avoid melting sea ice.

Over time, it gradually released fresh water into the Atlantic Ocean, where it could be slowly dispersed. The problem is that large quantities of fresh water have accumulated due to man-made climate change, and scientists fear more fresh water will be released. Tom Armitage, a polar scientist at NASA’s JPL, explains: “If the Beaufort vortex releases excess fresh water into the Atlantic Ocean, it may slow down its circulation. This will have an impact on the climate of the entire hemisphere, particularly in Western Europe. “
