2019 wasn't just the second-hottest year on record — the 2010s will go down as the hottest decade in human memory, per a new report.

Driving the news: The Copernicus Climate Change Service found "an unrelenting upward trend in temperatures as emissions of greenhouse gases trap heat in the atmosphere and change the climate," the N.Y. Times notes.

It's almost time to officially conclude that 2019 was the second-hottest year in temperature records that date back to the 1800s.

Driving the news: "It appears nearly certain (>99% likelihood) that 2019 will conclude as the second-warmest year since measurements began in 1850, behind only the exceptional warmth of 2016," the research group Berkeley Earth confirmed a few days ago.
