2020 in a dead heat for world's warmest year

New data from EU satellites shows that 2020 is in a statistical dead heat with 2016 as the world's warmest year.
The Copernicus Climate Change Service says that last year was around 1.25C above the long-term average.
The scientists say that unprecedented levels of heat in the Arctic and Siberia were key factors in driving up the overall temperature.
The past 12 months also saw a new record for Europe, around 0.4C warmer than 2019.
