In case you missed it, the World Meteorological Organization brought together multiple entities, including United Nations-affiliated organizations and others, to publish their collective information on the latest climate science at the end of the summer. Each organization wrote one or more chapters. The overall messages from these chapters include that greenhouse gases continued to increase in 2020 from 2019 despite a small reduction in the increase because of the COVID-19 pandemic; Paris Agreement greenhouse has emissions goals are not being met; the sea level is rising faster than the long-term average; the period 2016-2020 will likely be the warmest five years on record; and the extent of Arctic sea-ice continues to decrease with warming over the next five years continuing at twice the overall rate elsewhere around the globe.
