2018 was fourth hottest year on record: researchers
Update:: The last four years have been the world's hottest since record-keeping began, with 2018 the fourth warmest on record, according to data published Thursday by US research group Berkeley Earth. Temperatures in 2018 were around 1.16 degrees Celsius (2.09 degrees Fahrenheit) above the average temperature of the second half of the 19th century, from 1850-1900, often used as a pre-industrial baseline for global temperature targets. The European Union's Copernicus Climate Change Service published its own data on January 7 that also found 2015-2018 to be the hottest years on record.
