Arctic recorded record high temperatures in 2020, NOAA report finds


Last summer, Russia reached 100.4 degrees Fahrenheit. This is the highest temperature ever measured in the Arctic, according to the US National Oceanic and Atmospheric Administration’s annual climate report released Wednesday. With the help of record carbon dioxide concentrations on Earth, surface temperatures in the Arctic broke the 121 record in 2020.

“Today, scientists have warned again about the climate crisis,” said Eddie Bernice Johnson, chairman of the House Science and Technology Commission. statement Regarding the report. “Unfortunately, without swift action, we can expect to set such a new record each year.”

31st annual Climate report statusPublished by the American Meteorological Society and led by NOAA, is based on the work of more than 530 scientists in more than 60 countries. 2020 has been identified as one of the warmest three years in recorded history. Despite a 6% to 7% reduction in carbon dioxide emissions as a result of the pandemic outage, carbon dioxide emissions have reached the highest levels on Earth’s surface in at least the last 800,000 years.

“This clearly reminds us that the factors that lead to climate change are determined by a much longer time range than a year and have an inertia that requires considerable effort over a much longer period of time to stop. ..

The report found that the year-on-year increase in global carbon dioxide levels over the last half century has tripled, resulting in above-average temperatures around the world.

In Siberia, just north of the Arctic Circle, record temperatures have led to rapid snowmelt. In fact, the entire Eurasian continent had the fourth-lowest snowfall in May last year and the lowest-record snowfall in June.

Siberia, which is usually one of the coldest regions in the world, Worst fire year, Measured by the amount of carbon dioxide released into the atmosphere. Wildfires have become more common in the region over the last five years, and the number of fires is increasing each year. a few weeks ago, Smoke from wildfire It reached the North Pole for the first time in history.

Meanwhile, the report found that “extreme warmth” reached Antarctica in 2020 as atmospheric rivers brought unprecedented temperatures to the continent.

On February 6, 2020, Esperanza Base on the Antarctic Peninsula reached a record high of 64.94 degrees Fahrenheit. The heat brought about the greatest end of summer surface melting in 43 years, which affected more than half of the peninsula.

In 2020, we also saw the world’s highest sea level, the highest average ocean calorie, and most of the tropical cyclones ever recorded.

Earlier this month, the United Nations Intergovernmental Panel on Climate Change Impact of climate change Is “extreme” and “unprecedented” and is expected to worsen “unless significant reductions in carbon dioxide (CO2) and other greenhouse gas emissions in the coming decades”.

UN Secretary-General Antonio Guterres said the report was “Code Red for Mankind” and called for “immediate action on energy.”

“The alarm bells are deafening and the evidence is irrefutable. The burning of fossil fuels and the emission of greenhouse gases from deforestation choke our planet and put billions of people in imminent danger. We are exposed, “Guteres said. statement Early this month. “The heating of the earth affects every part of the globe, and many of the changes are irreversible.”
