James Hansen’s March 2022 global average temperature still trending up (close to all-time record for the month) when temps normally drop
By Hansen et al., 15/04/2022 from Climate Science, Awareness and Solutions, Columbia Univ,
March was notably warm (Fig. 1), more than 1.3°C warmer than the average March in 1880-1920, despite continued La Nina cooling of the Pacific. Because of the present planetary energy imbalance – discussed in prior posts – we expect 2022 to be substantially warmer than 2021. [my emphasis] The imbalance is due to surging growth rates of GHGs (greenhouse gases), solar irradiance rising from its recent minimum, and perhaps the aerosol forcing becoming less negative, although the latter remains speculative given the absence of measurements of the global aerosol forcing.
The imbalance – excess energy coming in – is not enough to push the 2022 annual temperature above the 2020 record, but it will soon do that. Meanwhile, models forecasting the tropics favor continuation of the La Nina this summer, which favors strong tropical storms.Read the complete article….
Editors note: Hansen’s Climate Science, Awareness and Solutions Lab in the Earth Institute at Columbia University is an excellent source of graphics summarizing the current state of global warming and the climate emergency
