The trend has been clear for some time: Our planet is getting warmer. The latest piece of evidence comes from the European Union's Copernicus Climate Change Service, or C3S, which announced Friday that 2020 tied with 2016 for the hottest year on record on a global scale.
The entire past decade has been unprecedented for global temperatures. "This makes the last six years the warmest six on record," C3S said in a statement. Last year was also the warmest on record for Europe, topping the previous record from 2019. According to NASA, "global temperature records start around 1880 because observations did not sufficiently cover enough of the planet prior to that time."
NOAA and NASA usually release an assessment of the previous year's temperatures in January as well, so we can expect those agencies to weigh in soon. Global temperatures are tracked using satellite data, climate models and statistical analysis.
