(a) Annual mean temperature anomalies in the Arctic (66.5∘–90∘N) (dark colours) and globally (light colours) during 1950–2021 derived from the various observational datasets. Temperature anomalies have been calculated relative to the standard 30-year period of 1981–2010. Shown are also the linear temperature trends for 1979–2021. (b) Annual mean temperature trends for the period 1979–2021, derived from the average of the observational datasets. Areas without a statistically significant change are masked out. (c) Local amplification ratio calculated for the period 1979–2021, derived from the average of the observational datasets. The dashed line in (b) and (c) depicts the Arctic Circle (66.5∘N latitude).

Image of the Day: Satellite view of Lake Mead in 2000 and 2022 – “Declining water levels due to climate change and 20 years of ongoing drought have reshaped the park’s shorelines”

By Michael Carlowicz 20 July 2022 (NASA Earth Observatory) – Continuing a 22-year downward trend, water levels in Lake Mead stand at their lowest since April 1937, when the reservoir was still being filled for the first time. As of July 18, 2022, Lake Mead was filled to just 27 percent of capacity. The largest reservoir in the […]
