Spring 2020 in southern U.S. arrives earlier than ever recorded, adding to climate trend

By Cassidy Randall 6 March 2020 (The Guardian) – Across the south-eastern US, trees are unfurling their clouds of leaves after winter. Yet this picturesque and usually welcome development is this year cause for consternation.

Observational and modeled climatology (contours) and trends (shading) of the zonal component of the near ocean surface wind. (a) Ensemble trends of the zonal near ocean surface wind based on the NCEP/NCAR, NCEP/DOE and NERA‐Interim reanalysis data sets covering 1979–2018. Stippling indicates regions where the trends pass the 95 percent confidence level (Student's t test). (b) Zonal near ocean surface wind change in the doubled CO2 simulations relative to the pre‐industrial control simulation carried out by AWI‐CM. Stippling indicates areas where the magnitude of the trend is larger than the standard deviation of the local variability. The subpanel at the right side of each graph shows the zonally averaged climatology (blue) and trend (red) of zonal near ocean surface wind.

Major wind-driven ocean currents are shifting toward the poles – “Over the past 40 years, all eight wind-driven surface current systems had shifted poleward”

24 February 2020 (AWI) – In the course of the past 40 years, the major wind-driven current systems in the ocean have steadily shifted toward the poles. Experts at the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI), came to this conclusion after analysing long-term global satellite data on the ocean surface […]

The boreal winter season 19/20 was by far the warmest winter season ever recorded in Europe – “Europe has been experiencing its mildest winter on record”

4 March 2020 (C3S) – With persistent mild weather over Europe, particularly in the north and east, the past winter was 3.4 °C warmer than the average winter for the period 1981-2010. The temperature was almost 1.4°C higher than that of the previous warmest winter, 2015/16. Back in November C3S seasonal predictions provided strong indications […]

These maps show nitrogen dioxide (NO2) values across China from 1 January 2020 to 20 January 2020 (before the quarantine) and 10 February 2020 to 25 February 2020 (during the quarantine). The data were collected by the Tropospheric Monitoring Instrument (TROPOMI) on ESA’s Sentinel-5 satellite. A related sensor, the Ozone Monitoring Instrument (OMI) on NASA’s Aura satellite, has been making similar measurements. Graphic: Joshua Stevens / NASA Earth Observatory
