hottest years on record
NASA also found that 2010-2019 was the hottest decade ever recorded. The years 1998, 2005, 2009, 2010, 2012, and 2013 also recorded high temperatures. This kind of record-breaking heat poses substantial risks to human health—particularly to the most vulnerable members of society. High ocean-heat content can contribute to sea-level rise. As per metrological records around the world, global temperatures have shown variations with some years recording higher temperatures as compared to others. Through instrumental temperature record, earth’s climatic system temperatures are obtained whereby both oceanic and surface air temperatures are recorded. The global numbers are in, and 2019 was the 2nd warmest year on record—wrapping up the hottest decade ever recorded. By Rotich Kiptoo Victor on May 25 2018 in World Facts. The annual globally averaged sea surface temperature was the second highest on record at 1.39 degrees F (0.77 of a degree C) above the 20th-century average and just behind 2016. As a result, it is considered the fifth hottest year on record and is followed by the year 2013, which recorded a temperature deviation as high as 0.66°C, making it the sixth warmest year on record. 2014’s temperature deviation of 0.74°C made a constant rise in global temperatures from 2014 to 2016. Nine of the 10 warmest years have occurred since 2005, with the last five years comprising the five hottest.
Since a significant rise in temperatures have been recorded in recent years, it can be concluded that there is a high probability of higher temperatures in future. Ocean heat content, which describes the amount of heat stored in the upper-levels of the ocean, was the highest ever recorded. Read More, Members of the Climate Central staff and board are among the most respected leaders in climate science. 2010 had a temperature deviation of 0.7°C. 2015 and 2017 came close in second and third respectively with temperature deviations of 0.9°C and 0.84°C respectively. Higher temperatures can also increase the risk of wildfires, which flared up across the globe from closer to home in Alaska and California, to Siberia and Indonesia. December 2019 was near-record warm: The month was in fact Earth’s second-hottest December on record, logging an average temperature 1.89 degrees F (1.05 degrees C) above the 20th-century average. (NOAA NCEI and NOAA Climate.gov). The global numbers are in, and 2019 was the, The 2016 Paris Agreement set a commitment to keep the global average temperature well, Seemingly small increases in long-term average temperatures lead to a rise in the, Warmer temperatures can have a range of other impacts, such as, To keep warming below 2°C will necessitate a global effort to drastically reduce emissions. Continents baked: Parts of central Europe, Asia, Australia, southern Africa (including the island of Madagascar), New Zealand, Alaska, Mexico and eastern South America had record-high average land temperatures in 2019. Title: JPG • PNG | No Title: JPG • PNG. Another factor which leads to the rise in global temperatures is the natural conditions of volcanic eruptions and El Nino. Climate Central compares temperatures to an earlier 1880-1910 baseline to assess warming during the industrial era. Increased industrialization and cases of deforestation may lead to increased greenhouse gases. The other years include 2005, 2009, 1998, and 2012, which are considered as seventh, eighth, ninth, and tenth hottest years on record. In order to examine 2019 global temperatures in the context of this goal, we compare them to an earlier 1880-1910 baseline. Read More. It was also the 43rd consecutive year with global land and ocean temperatures, at least nominally, above average. Estimates of the area burned vary from 15 million to 27 million acres. The declining state of sea ice: Polar sea ice coverage continued its downward trend in 2019. NASA also found that 2010-2019 was the hottest decade ever recorded. An independent organization of leading scientists and journalists researching and reporting the facts about our changing climate and its impact on the public. The year 2016, with a temperature deviation of 0.94°C, is considered to be the hottest year on record. Both the Arctic and Antarctic oceans recorded their second-smallest average annual sea-ice coverage during the 1979–2019 period of record.
The globally averaged sea surface temperature was 1.19 degrees F above average, while the land surface temperature was 2.02 degrees above average, both the fourth highest on record. Top 10 Warmest Years on Record Published: January 15th, 2020 The global numbers are in, and 2019 was the 2nd warmest year on record—wrapping up the hottest decade ever recorded . Among the significant factors behind the rising temperatures on earth are the greenhouse gases. Small differences in their calculations arise as NASA’s calculations are extrapolated to account for polar locations with poor station coverage, while NOAA relies more heavily on the polar station data. The temperature deviations of these years, 2005, 2009, 1998, and 2012, was 0.65°C, 0.64°C, 0.63°C, and 0.62°C respectively. The UK data adds to a global picture of a planet that’s heating up, with this July on track to be the hottest month ever recorded on Earth, and 2019 expected to be the second hottest year. In January 2017, several scientific agencies around the world, including NASA and the NOAA in the United States and the Met Officein the United Kingdom, named 2016 the warmest year recorded. The last ten years have seen a rise in global temperatures.
While it’s important to note that a warming world will have year-to-year variations due to natural variability (so not every year will be warmer than the one before) 2019 was 1.22°C (2.19°F) above the pre-industrial baseline temperature. It is estimated that greenhouse gases raise global temperatures by about 15°C; thus, the absence of these gases would have resulted to an average temperature on the earth’s surface at -18°C, which is 0°F. National Oceanic and Atmospheric Administration, National Centers for Environmental Information, NASA scientists, who conducted a separate but similar analysis, concurred with NOAA’s ranking, NOAA NCEI’s 2019 climate report and images, Earth just had its hottest September on record, Northern Hemisphere just had its hottest summer on record. Such conditions will lead to global warming which is a condition of excess heat all over the world and has adverse effects on life. Leaving behind the warmest decade on record reminds us of the challenge ahead, but also of the opportunity in the years to come. The IPCC report stated that to limit warming to 1.5°C would require roughly, Calculations of average annual global temperature are performed independently at, below 2°C (3.6 °F) above pre-industrial levels, Could Kennedy Space Center launch pads be at risk as climate changes? Greenhouse gases are responsible for the absorption of heat from the atmosphere and retain it over long periods. Also, solar activity may affect the rise in global temperatures since heat emitted by the sun may vary according to earth’s position to that of the sun. The last slide shows the departure from average for the entire year. The average temperature across the globe in 2019 was 1.71 degrees F (0.95 of a degree C) above the 20th-century average and just 0.07 of a degree F (0.04 of a degree C) cooler than the 2016 record. Australia experienced its hottest and driest year on record, contributing to the devastating wildfires. Only December 2015 was warmer. METHODOLOGY: Calculations of average annual global temperature are performed independently at NASA and NOAA.
