American Meteorologicfal Society - 2018 4th-Hottest Year On Record, After 2016, 2015 And 2017

Global surface temperature anomaly, 1850-2018. In 2018, global surface temperature was near-record high. The globally averaged surface temperature was 0.30°C to 0.40°C above the 1981–2010 average, depending upon the dataset used. This places 2018 as having the fourth warmest annual global temperature since records began in the mid- to late 1800s. The four warmest years on record have all occurred since 2015. Data: NOAA.

12 August 2019 (NCEI) – A new State of the Climate report confirmed that 2018 was the fourth warmest year in records dating to the mid-1800s.

Last year was the fourth warmest year on record despite La Niña conditions early in the year and the lack of a short-term warming El Niño influence until late in the year. The report found that the major indicators of climate change continued to reflect trends consistent with a warming planet. Several markers such as sea level and greenhouse gas concentrations in the atmosphere once again broke records set just one year prior.

These key findings and others are available from the State of the Climate in 2018 report released online today by the American Meteorological Society (AMS).

The 29th annual issuance of the report, led by NOAA National Centers for Environmental Information, is based on contributions from more than 470 scientists from nearly 60 countries around the world and reflects tens of thousands of measurements from multiple independent datasets (highlights, full report). It provides a detailed update on global climate indicators, notable weather events, and other data collected by environmental monitoring stations and instruments located on land, water, ice, and in space.
