Overall, Europe's annual temperature has increased at an average rate of 0.22°F (0.12°C) per decade since 1910; however, it has almost quadrupled to 0.77°F (0.43°C) since 1981. The national average precipitation total was 48.5 mm (1.9 inches), which is 150% of June's normal. Members of the news media may also use the materials in this report for any new reporting purpose provided that Berkeley Earth is properly acknowledged, without concern for whether or not the CC BY-4.0 license is followed. After all, that shows exactly why all this is happening. By contrast, 2018 began with a weak-to-moderate La Niña event. Record warm temperatures were measured across much of Europe and the Mediterranean Sea, the Middle East, New Zealand and surrounding ocean, and across parts of Asia, the Atlantic Ocean and the western Pacific Ocean. In 2018, no places on Earth experienced a record cold annual average. The 1910–2018 trend for Oceania was +0.11°C (+0.20°F) per decade; however, the trend is twice that during the 1981–2018 period (+0.21°C / +0.38°F) per decade. Northern Hemisphere snow cover: According to NOAA data analyzed by the Rutgers Global Snow Lab, the average annual Northern Hemisphere snow cover extent for 2018 was 9.90 million square miles. Oceania, as a whole, had its third warmest year on record at 1.15°C (2.07°F) above average. A prolonged period of winter warmth in Antarctica is also visible. The annual global temperature from 2000 to 2009 was 0.61 °C (1.1 °F) higher than the average temperature for … The Gulf of Mexico and the Hawaiian region's 2018 temperature were both the third highest on record. Since 2018 was colder than 2015 by only 0.04 °C (0.06 °F), the ranking of 3rd versus 4th warmest year can reasonably be regarded as ambiguous. Though 2018 only ranks fourth overall, 2015 through 2018 still stand out as a period of significant warmth well above all previous years since 1850. Much-warmer-than-average conditions were present across Europe for most of 2018, with eight of 10 months ranking among the three warmest respective months on record. Meanwhile, Nacocolevu set a new February precipitation record of 727.4 mm (28.6 inches), exceeding the previous record of 576.6 mm (22.7 inches) set in 2017. The weather station data is combined with sea surface temperature data from the UK Met Office’s Hadley Centre (HadSST). Berkeley Earth gives you historical temperature data for your home town, state, and country. The year 1998 is the only year from the 20th century among the ten warmest years on record, currently tying with 2009 as the ninth warmest year on record. Managing Editor: Taking this into account, NASA estimates that 2018’s global mean change is accurate to within 0.1 degree Fahrenheit, with a 95 percent certainty level. Clim., 18, 2021-2036. This color-coded map displays a progression of changing global surface temperature anomalies from 1880 through 2018. Temperatures during March 2018 were 9.0°–12.0°C (16.2°–21.6°F) above average and were similar to temperatures observed typically at the end of May or early June. Global land surface temperature: For December, the globally averaged land surface temperature was 2.11°F (1.17°C) above the 20th century average and tied with 1939 as the eighth warmest December in the 1880–2018 record. Hong Kong, China also had warmer-than-average conditions during the month, with a temperature departure from average of 1.7°C (3.1°F) above average and ranked among the four highest March temperatures on record. Precipitation totals across the Island of Fiji were above average to well above average, with the exception of Rotuma which was the only station that had below-average precipitation during October 2018. Earth's global surface temperature in 2018 was the fourth warmest since 1880, according to independent analyses by NASA and the National Oceanic and Atmospheric Administration (NOAA). GISS (Goddard Institute for Space Studies). Precipitation totals across the Island of Fiji were average to well above average in February, with only 3 of 24 stations experiencing drier-than-average conditions. Keep current with the latest independent, non-governmental, and unbiased research. That exceptional El Niño boosted global mean temperatures in 2015 and 2016. The following chart compares Berkeley Earth’s analysis of global mean temperature to that of the other groups, though only Berkeley Earth and ECWMF data have been updated through 2018.

NASA uses the unique vantage point of space to better understand Earth as an interconnected system. Since the 1880s, the average global surface temperature has risen about 2 degrees Fahrenheit (1 degree Celsius). Globally, 2018's temperatures rank behind those of 2016, 2017 and 2015. This reflects the long-term trend towards global warming. Of note, Seoul broke a 111-year record with a monthly maximum temperature of 39.6°C (103.3°F). The national March 2018 precipitation total was 26.7% below the 1961–90 average. Headquarters, Washington According to the United Kingdom's Met Office, the national precipitation total for the month was 48% of June's normal value, with the most notable precipitation deficits across England and Wales. This report is based on such weather observations as had been recorded into global archives as of early January 2018. Antarctic sea ice extent: Antarctic sea ice during December was 3.49 million square miles, according to analysis by the National Snow and Ice Data Center. According to the World Meteorological Organization's Weather and Climate Extremes Archive, Africa's highest maximum temperature of 55.0°C (131.0°F) was set in Kebili, Tunisia in July 1931. The following map qualitatively categorizes local temperatures in 2018 based on how different they were from historical averages after accounting for the typical climate variability at each location. For more information about NASA’s Earth science missions, visit: Steve Cole In reconstructing the changes in global mean temperature since 1850, Berkeley Earth has examined 19 million monthly-average temperature observations from 46,000 weather stations. Though a transition to weak El Niño conditions had been predicted for the end of 2018, the temperature patterns in the Pacific at the end of the year remain weak and unconsolidated. The 2018 temperature for Asia as 1.26°C (2.27°F) above average and the seventh highest in the 109-year record. World map color-coded to show differences in average annual temperatures (in degrees Celsius) for 2000 - 2009 compared with 1951 - 1980. The national mean January 2018 temperature for New Zealand was 20.3°C (68.5°F), which is 3.1°C (5.6°F) above the 1981–2010 average. If the Paris Agreement’s goal of no more than 1.5 °C (2.7 °F) warming is to be reached, significant progress towards reducing greenhouse gas emissions must be made soon. Africa had its fifth warmest year on record at 1.01°C (1.82°F). Mexico had its driest July on record, receiving only 83.8 mm (3.3 inches), which is 60% of July's long-term average (1941—2018). However, according to NCEI's Global Historical Climatology Network - Daily, a higher minimum temperature of 43.3°C (110°F) occurred in Furnace Creek (formerly known as Greenland Ranch) located in California's (United States) Death Valley National Park on 5 July 1918. We conclude that 2018 was likely the fourth warmest year on Earth since 1850. Smith, et al (2008), Improvements to NOAA's Historical Merged Land-Ocean Surface Temperature Analysis (1880-2006), J. The slight decline in 2018 is likely to reflect short-term natural variability, but the overall pattern remains consistent with a long-term trend towards global warming. The record year was set in 2013 at +1.25°C (+2.25°F). During 2018, 11 of 12 monthly global land and ocean temperature departures from average ranked among the five warmest for their respective months, giving way to the fourth warmest year in NOAA's 139-year record. No land areas were record cold for the year. Vose, 1997: An Overview of the Global Historical Climatology Network Database. The 2018 temperature across South America was the eighth highest on record. A new study tracing the sources of carbon dioxide, the most significant human-generated greenhouse gas, reveals the unexpectedly large influence of vegetation in urban environments. The years 2015–2017 each had a global temperature departure from average that was more than 1.0°C (1.8°F) above the 1880–1900 average, which is a period that is commonly used to represent the pre-industrial conditions.
