As this year and decade come to a close, the World Meteorological Organization (WMO) paused and considered some inconvenient truths. Namely, that it has been the hottest decade on record, and that 2019’s experienced the second- or third-highest temperatures ever recorded.
According to the WMO’s report, not only have temperatures for the past 10 years been higher than any prior decade, but the concentration of greenhouse gas in the atmosphere has continued to rise in 2019 from the eye-watering level of 407.8 parts per million in 2018.
