The year 2020 was one of the three hottest years on record, marked by wildfires, droughts, floods and melting glaciers, a United Nations report said on Monday, prompting the UN Secretary-General to say the world stands "on the verge of the abyss". “Whether one year is a record or not is not really that important; the important things are long-term trends. Earth’s warming trends are most pronounced in the Arctic, which the GISTEMP analysis shows is warming more than three times as fast as the rest of the globe over the past 30 years, according to Schmidt. The satellite surface temperature record from the Atmospheric Infrared Sounder (AIRS) instrument aboard NASA’s Aura satellite confirms the GISTEMP results of the past seven years being the warmest on record. Temperature averages across the last five years, and across the last 10-year period, "are also the warmest on record", it added. Satellite measurements of air temperature, sea surface temperature, and sea levels, as well as other space-based observations, also reflect a warming, changing world. Almost all land surfaces on the planet experienced unusually warm temperatures. The values represent surface temperatures averaged over the entire globe for the year. Tracking global temperature trends provides a critical indicator of the impact of human activities—specifically, greenhouse gas emissions—on our planet. NASA/SASKIA MADLENER By Maria Temming February 10, 2021 at 6:30 am Pandemic stay-at-home orders may have … The GISS temperature analysis (GISTEMP) is accurate to within 0.1 degrees Fahrenheit, with a 95 percent confidence level for the most recent period. In turn, the Arctic Ocean absorbs more heat and causes temperatures to rise further still. Earth’s average temperature has risen more than 1.2°C (2°F) since the late 19th century. Heat 2019 previously held this record, where observed temperatures were 0.4 degrees Celsius higher than the same period. A separate, independent analysis by the National Oceanic and Atmospheric Administration (NOAA) concluded that 2020 was the second-warmest year in their record, behind 2016. Temperatures are increasing due to human activities, specifically emissions of greenhouse gases, like carbon dioxide and methane. Flight Center, NASA Goddard Institute for Space Studies (2021), NOAA National Centers for Environmental Information (2021, January 14), NASA Earth Observatory (2018, October 19), NASA Earth Observatory (2015, January 21). The 2020 GISS values represent surface temperatures averaged over both the whole globe and the entire year. Science Editor: The animation below shows the seasonal cycle in global temperature anomalies for every month since 1880. In contrast, global shutdowns related to the ongoing coronavirus (COVID-19) pandemic reduced particulate air pollution in many areas, allowing more sunlight to reach the surface and producing a small but potentially significant warming effect. Each line shows how much the global monthly temperature was above or below the global mean of 1980–2015. Image of the Day Extreme weather combined with COVID-19 in a double blow for millions of people in 2020. Part II: From the vantage point of space, NASA’s fleet of Earth-observing satellites investigates connections between ecosystems that are continents apart, or right next door. At the same time Arctic sea ice has been declining by about 13 percent per decade, which causes the region to reflect less sunlight (lower albedo). The record-warm July continued a streak of ten consecutive months that have set new monthly high-temperature records. Like all scientific data, these temperature findings contain a small amount of uncertainty—in this case, mainly due to changes in weather station locations and temperature measurement methods over time. Remote Sensing. Warmer waters melt more ice off Greenland and Antarctica, raising sea levels. The Australian bush fires during the first half of the year burned 46 million acres of land, releasing smoke and other particles more than 18 miles high in the atmosphere, blocking sunlight and likely cooling the atmosphere slightly. Annie Mac's listeners voted in their thousands for 2020's Hottest Record of the Year: Bring Me the Horizon and YUNGBLUD's 'Obey'. 2020 as ranked by other scientific organizations. Hottest decade. The New UN Climate Report in One Sentence. The largest source of year-to-year variability in global temperatures typically comes from the El Nino-Southern Oscillation (ENSO), a naturally occurring cycle of heat exchange between the ocean and atmosphere. Managing Editor: While the long-term trend of warming continues, a variety of events and factors contribute to any particular year’s average temperature. 2020 is just two-hundredths of a degree cooler than 2016, the hottest year ever recorded. This phenomenon is known as Arctic amplification. NASA scientists, who conducted a separate but similar analysis, have determined that 2020 ties 2016 as the warmest year on record, sharing the first-place spot.. Scientists from Copernicus also have 2020 tying with 2016 as the warmest year on record, while the United Kingdom Met Office ranked 2020 as the second-warmest year on … Throughout the year, temperature records were shattered worldwide. Scientists from Europe’s Copernicus program also have 2020 tying 2016 as the warmest year on record, while the UK Met Office ranked 2020 as the second-warmest. Randal Jackson The team assembles its analysis with publicly available data from roughly 6,300 meteorological stations, ship and buoy-based observations, and Antarctic research stations. While the year has ended in a negative (cool) phase of ENSO, it started in a slightly positive (warm) phase, which marginally increased the average overall temperature. Land. Heat Credits: NASA’s Scientific Visualization Studio/Lori Perkins/Kathryn Mersmann NASA shares this unique knowledge with the global community and works with institutions in the United States and around the world that contribute to understanding and protecting our home planet. The six warmest years on record have all been since 2015 and decade of 2011-2020 was the warmest decade on record. A separate, independent analysis by the National Oceanic and Atmospheric Administration (NOAA) concluded that 2020 was the second-warmest year in their record, behind 2016. Satellite measurements of air temperature, sea surface temperature, and sea levels, as well as other space-based observations, also reflect a warming, changing world. The cooling from the negative phase is expected to have greater influence on 2021. The warmest six years have all been since 2015, with 2016, 2019 and 2020 being the top three. 2020 Earth’s global average surface temperature. 2020 was warmest year on record for Earth’s oceans Ocean waters may have absorbed enough heat to boil 1.3 billion kettles of water Earth’s oceans are heating up. 2011-2020 was the warmest decade on record. GISS Surface Temperature Analysis (GISTEMP). These seasonal anomalies are drawn from the Modern-Era Retrospective analysis for Research and Applications, version 2 (MERRA-2), a model run by NASA’s Global Modeling and Assimilation Office. NASA Earth Observatory images by Joshua Stevens, based on data from the NASA Goddard Institute for Space Studies. The Corona pandemic brought the economies of the world to their knees over the past year, but it has hardly helped the climate. Parts of Earth are warming faster than others, with warming trends most pronounced in the Arctic. But that would be a false conclusion, because 2020’s heat rose in a year when the world was experiencing a La Niña weather pattern, which normally means lower temperatures. These raw measurements are analyzed using an algorithm that considers the varied spacing of temperature stations around the globe and urban heating effects that could skew the conclusions if not taken into account. Climate records have fallen like dominos in the past decade, so notching up merely the third hottest year on record may seem to suggest some respite. Heat. The largest source of year-to-year variability in global temperatures typically comes from the El Nino-Southern Oscillation (ENSO), a naturally occurring cycle of heat exchange between the ocean and atmosphere. They noted that 2020 was the 44th consecutive year with global land and ocean temperatures above the 20th-century average. These shutdowns also appear to have reduced the amount of carbon dioxide (CO2) emissions last year, but overall CO2 concentrations continued to increase, and since warming is related to cumulative emissions, the overall amount of avoided warming will be minimal. 2020 has tied with 2016 as the hottest year on record, marking the end of the hottest decade in the books as the world grapples with global climate change, according to a study released Friday. NASA’s analysis incorporates surface temperature measurements from more than 26,000 weather stations and thousands of ship- and buoy-based observations of sea surface temperatures. The six years since 2015 have been the warmest on record. NOAA scientists use much of the same raw temperature data in their analysis, but have a different baseline period (1901-2000) and methodology. NASA’s full 2020 surface temperature data set and the complete methodology used to make the temperature calculations are available online. 2020 was Earth’s second hottest year, just behind 2016. Story derived from NASA and NOAA press releases by Michael Carlowicz. Earth’s global average surface temperature in 2020 tied with 2016 as the warmest year on record, according to an analysis by NASA. The cooling influence from the negative phase is expected to have a larger influence on 2021 than 2020. Temperature Extremes. Earth’s global average surface temperature in 2020 tied with 2016 for the warmest year on record, according to an analysis by NASA. Heat “The lack of a similar assist from El Niño this year is evidence that the background climate continues to warm due to greenhouse gases.”. Rising temperatures are causing phenomena such as loss of sea ice and ice sheet mass, sea level rise, longer and more intense heat waves, and shifts in plant and animal habitats. Daniel Bailey. Globally, 2020 was the hottest year on record, effectively tying 2016, the previous record. According to NOAA, parts of the continental United States experienced record high temperatures in 2020, while others did not. The tool will help people, including resource managers and other officials, address increasing concentrations of methane and carbon dioxide in the atmosphere. “The last seven years have been the warmest seven years on record, typifying the ongoing and dramatic warming trend,” said GISS Director Gavin Schmidt. Less carbon dioxide was released in 2020. But that doesn’t change the long-standing trend: 2019 and 2020 are both virtually the hottest year on record. The GISS temperature analysis (GISTEMP) is accurate to within 0.1 degrees Fahrenheit with a 95% confidence level for the most recent period. Image of the Day “The previous record warm year, 2016, received a significant boost from a strong El Niño,” Schmidt said. The Northern Hemisphere saw its hottest year on record at 2.30 degrees F (1.28 degrees C) above the 20th-century average. Earth’s global average surface temperature in 2020 tied with 2016 as the warmest year on record, according to an analysis by NASA. The WMO said 2020 seemed on course to be the second-hottest year ever. Image of the Day A separate, independent analysis by the National Oceanic and Atmospheric Administration (NOAA) concluded that 2020 was the second-warmest year in their record, behind 2016. The bar chart below shows this year in the context of the past 140 years in the modern temperature record. Unlike NASA, NOAA also does not infer temperatures in polar regions lacking observations, which accounts for much of the difference between NASA and NOAA records. The year was slightly warmer than 2016 but within the margin of error of the analysis, making the years effectively tied. In the long term, parts of the globe are also warming faster than others. Scientists at NASA report each year on the long-term trend of rising air temperatures over Earth’s land and sea surfaces. This warmng also supercharges tropical storms. 2020 was Australia's fourth-hottest year on record, 1.15°C above Australia's 1961-to-1990 average, according to the Bureau of Meteorology. NOAA scientists use much of the same raw temperature data in their analysis, but have a different baseline period (1901-2000) and methodology. 2020 Was the One of the Hottest Years on Record Officials from NASA and NOAA say the warming of both the planet’s air and water are driving weather disasters. July 2017 was statistically tied with July 2016 as the warmest month in 137 years of modern record-keeping. 2020 was the warmest year on record in Europe, coming 1.6 degrees Celsius above the average temperature from 1981 to 2010, according to the Copernicus analysis. “The last seven years have been the warmest seven years on record, typifying the ongoing and dramatic warming trend,” said GISS Director Gavin Schmidt. The average land and ocean surface temperature across the globe in 2020 was 1.76 degrees F (0.98 of a degree C) above average — just 0.04 of a degree F (0.02 of a degree C) cooler than the 2016 record. Overall, Earth’s average temperature has risen more than 2 degrees Fahrenheit since the 1880s. This phenomenon, known as Arctic amplification, is driving further sea ice loss, ice sheet melt and sea level rise, more intense Arctic fire seasons, and permafrost melt. Teams are headed out by land, water, and air to collect data that will be used to forecast land gain and loss in the Mississippi River Delta as a result of sea level rise. According to Schmidt, the region has been warming more than three times as fast as the rest of the globe over the past 30 years. Like all scientific data, these temperature findings contain a small amount of uncertainty – in this case, mainly due to changes in weather station locations and temperature measurement methods over time. Science Editor: Lee esta historia en español aquí. NOAA scientists use much of the same raw temperature data in their analysis, but have a different baseline period (1901-2000) and methodology. NASA measures Earth's vital signs from land, air, and space with a fleet of satellites, as well as airborne and ground-based observation campaigns. Bring Me The Horizon and YUNGBLUD have beat the likes of Billie Eilish and Phoebe Bridgers to win the title of Annie Mac’s Hottest Record of the Year 2020.. 2020 edged out 2016 by a very small amount, within the margin of error of the analysis, making the years effectively tied for the warmest year on record. It does not show absolute temperatures; instead, it shows how much warmer or cooler each region of Earth was compared to the baseline average from 1951 to 1980. A NASA study has confirmed with direct evidence that human activities are changing Earth's energy budget, trapping much more energy from the Sun than is escaping back into space. 2020 ties record for the hottest year ever, NASA analysis shows By Chelsea Gohd 15 January 2021 While 2020 was technically hotter than 2016, the two years have effectively tied. Continuing the planet’s long-term warming trend, the year’s globally averaged temperature was 1.84 degrees Fahrenheit (1.02 degrees Celsius) warmer than the baseline 1951-1980 mean, according to scientists at NASA’s Goddard Institute for Space Studies (GISS) in New York. A separate, independent analysis by the National Oceanic and Atmospheric Administration (NOAA) concluded that 2020 was the second-warmest year in their record, behind 2016. The climate crisis continued its relentless march in 2020, as the year has tied with 2016 as the warmest year on record. Atmosphere NOAA scientists use much of the same raw temperature data in their analysis, but have a different baseline period (1901-2000) and methodology. With these trends, and as the human impact on the climate increases, we have to expect that records will continue to be broken.”, Get NASA's Climate Change News: Subscribe to the Newsletter ».
