Previous year was fourth hottest on record: outlook sizzling - United Nations

"The global average temperature between now and 2023 is predicted to remain high, potentially making the decade from 2014 the warmest in more than 150 years of records".

Two US agencies, the United Kingdom Met Office and the WMO have analysed global temperatures in slightly different ways, but each came to the same conclusion on Wednesday: 2018 was the fourth-warmest year on record behind 2016, 2015 and 2017.

The average global temperature during 2018 was 1.42 degrees F above the 20th-century average. Nine of the 10 warmest years on record have all occurred since 2005.

Due to the dynamic character of global weather patterns, not every place of the Earth experiences the same levels of warming.

The strongest warming trends are seen in the Arctic region with continued loss of sea ice in 2018. NASA adds that the melting of Greenland and Antarctic ice sheets contributed to a rise in sea level.


The United Nations says the world is now on track for a temperature rise of 3C or more by 2100.

The polar vortex event last month that saw record lows across the American Midwestern states, leading to several deaths, is a result of a weakening of the jet stream and the kind of weather event that scientists fear will become more frequent as the temperature in the Arctic continues to rise.

Schmidt attributes this warming to be largely driven by increased emissions into the atmosphere of carbon dioxide and other greenhouse gases caused by human activities.

"The impacts of long-term global warming are already being felt - in coastal flooding, heat waves, intense precipitation and ecosystem change".

NASA's data takes temperatures from 6,300 weather stations along with ship and buoy-based observations of sea surface temperatures along with measurements from Antarctic research stations.
