Map showing rainfall anomalies (percentage) for seasons of 2020 in the UK. This was the fifth wettest year for UK in a series from 1862, and the wettest year since 2000. It was a particularly wet year across parts of north-west England and south-west Scotland which received more than 125% of average fairly widely, and some locations recorded more than 135% of average. Winter refers to the period December 2019 to February 2020. Note that winter 2021 (December 2020 to February 2021) will appear in State of the UK Climate 2021. Graphic: Met Office

Western Monarch butterfly abundance at 149 overwintering sites in California, 2017-2021. These critically low numbers follow two years with fewer than 30,000 butterflies—the previous record lows, indicating that the western monarch butterfly migration is nearing collapse. Sites were visited during both the Thanksgiving and New Year’s Counts during the 2020–2021 count season. Graphic: Xerces Society
