“We may be closer than we thought to dangerous climate thresholds”
A new study identifies an extra 0.1°C of human-caused warming. It turns out that 2015 was the first year on record that passed the 1°C (1.8°F) mark. It means that 2016 was approximately 0.1°C (0.2°F) warmer than we had thought relative to the pre-industrial time period. To put this in perspective, it is almost an extra decade of warming.
