Last year was officially the second hottest year ever recorded, shocking figures reveal.
Data from European scientists at Copernicus Climate Change Service (C3S) also shows 2019 was the warmest ever in Europe, as many regions suffered heatwaves and drought.
The data confirms the worst forecasts from previous research at the end of last year, which predicted that 2019 would be either the second or third hottest on record.
New data now reveals that the average temperature around the world was just 0.04°C lower than in 2016, which was the hottest year on record.
This was due to the once-in-a-century 'El Nino' phenomenon in 2016, which inflated the Earth's average surface temperature by 0.12°C.

Last year was officially the second hottest year ever recorded, shocking figures from European scientists at Copernicus Climate Change Service (C3S) reveal
Greenhouse gases have continued to increase and reached record highs in 2019, helping make this year one of the hottest on record. Ongoing computer models it will likely be the second or third hottest year ever, behind the freakishly warm year of 2016
The last five years have been the hottest on record, and the period of 2010-2019 was the hottest decade since records began, C3S said.
Globally temperatures in 2019 were 0.6°C warmer than the 1981-2010 average.
Earth's temperature over the last five years was 1.1°C-1.2°C warmer than pre-industrial times.
'2019 has been another exceptionally warm year, in fact the second warmest globally in our dataset, with many of the individual months breaking records,' said Carlo Buontempo, head of C3S.
CO2 concentrations are now also officially the highest they have been for at least 800,000 years.
The United Nations said last year that man-made greenhouse gas emissions needed to tumble 7.6 per cent each year to 2030 in order to limit temperature rises to 1.5°C - the more ambitious cap nations signed up to in the landmark Paris climate deal.
Current pledges to cut emissions put Earth on a path of several degrees warming by the end of the century.

The analysis of satellite data indicates that carbon dioxide concentrations have continued to rise in recent years, including in 2019
