Sea ice volume was the fourth lowest on record in 2020, and there has been a clear downward trend in sea ice volume over the past few decades. Annual temperatures between 1979 and 2019 are shown in black for each record, while the likely range (95% confidence interval) of the 2020 annual temperature based on the first six months of the year is shown by the red bar (see methodological note at the end for details). Months that were the warmest or tied for the warmest on record are highlighted in green. Arctic sea ice extent was at record low levels for much of the summer and the summer minimum clocked in as the second lowest on record after 2012. The year 2016, with a temperature deviation of 0.94°C, is considered to be the hottest year on record.

The year 2015 set the record for the warmest in the average world temperature by 0.90° Celsius above the average 20th Century temperature of 13.9° Celsius. Average temperatures for the five-year (2015-2019) and ten-year (2010-2019) periods were the highest on record. All rights reserved. While 2016’s warmth was buoyed by a super El Niño event that faded later in the year, 2020 has been remarkable in that its exceptional early year warmth happened during El Niño-neutral conditions. Burt and Herrera have called out similar issues with the Death Valley and Kebili readings from the 1910s and 1930s. Increased industrialization and cases of deforestation may lead to increased greenhouse gases. 2010 had a temperature deviation of 0.7°C. How hot was it at the Furnace Creek visitor center at Death Valley national park on 16 August 2020? This marked the third consecutive year reaching a new record temperature, the first time since the current warming trend began in the 1970s that three years in a row were record highs. While competing events jostle for our attention, the machinery driving the climate crisis lumbers onward. The only readings hotter than Sunday’s that are recognized by WMO are 134F (56.7C) at Death Valley on 10 July 1913, and 131F (55C) at Death Valley on 13 July 1913, and at Kebili, Tunisia, in July 1931. 2019 was the second warmest year since record-keeping began in 1880, and the 2010s were by far the warmest decade. North Carolina, with an average temperature of 49.7 F so far this year, tied a record set in 1990. Earth’s 2016 surface temperatures were the warmest since modern recordkeeping began in 1880, according to independent analyses by NASA and the National … By entering your email address you agree for your data to be handled in accordance with our Privacy Policy. Arctic sea ice extent was at extremely low levels for much of the summer of 2020, setting new records every day during the month of July. Scientific American is part of Springer Nature, which owns or has commercial relations with thousands of scientific publications (many of them can be found at, How the Senate Race Could Shape Future U.S. NOAA in particular went from 2020 only having around a 43% chance of setting a new record to having a 61% chance (NOAA’s own model gives their dataset a slightly higher 65% chance).

July 2020 was the hottest … (Note: at the time of writing, September data was not yet available for the Hadley/UEA or Cowtan and Way temperature records.). While predicting the course of La Niña and El Niño events is challenging, it does make it likely that 2021 will be at least modestly cooler than 2020. This year there was only half as much sea ice during the September minimum in 2020 than there was in the late 1970s and early 1980s. Parsing the planet’s highest temperature by degrees, or tenths of degrees, may seem like a pedantic task in the face of a global climate crisis with vast consequences. This year has been especially warm in Eastern Europe and Asia, where average temperatures were at least 7.2 F above the historical average, NOAA reported. If CO2 and N2O emissions remain flat, on the other hand, atmospheric concentrations would continue to increase. By Rolando Y. Wee on April 25 2017 in Environment.
