Big freeze to grip Britain before weekend downpour hits – 178 flood alerts still in effect

By Dan Keane 6 March 2020 (The Sun) – Temperatures are set to drop by another -6C before another weekend of rain hits the country after weeks of heavy rainfall. Flooding alerts are still in place, and this weekend could bring more wet weather with heavy wind also expected. This will be the fifth weekend in a […]

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 […]

Winter 2019/2020 warmest on record in Moscow, first winter to average above freezing – Temperature milestones set across Europe and North America – German ice wine harvest fails for first time on record

By Andrew Freedman 2 March 2020 (The Washington Post) – The meteorological winter of 2019-2020 shattered temperature records in Russia and France as well as other parts of Europe and the United States. In Moscow, this was the warmest winter in nearly 200 years of record-keeping, and the first winter there to have an average […]

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

Airborne nitrogen dioxide plummets over China as quarantine shuts down industry

By Kasha Patel 28 February 2020 (NASA) – NASA and European Space Agency (ESA) pollution monitoring satellites have detected significant decreases in nitrogen dioxide (NO2) over China. There is evidence that the change is at least partly related to the economic slowdown following the outbreak of coronavirus. At the end of 2019, medical professionals in […]

The “blue acceleration”: Study shows humans’ surging incursions into the sea

By Grace Dungey 13 February 2020 (Mongabay) – Humanity has depended on the ocean for millennia. Today, however, the rush to the sea is occurring with unprecedented diversity and intensity, propelled by population growth and demand for diminishing terrestrial resources. A study published in January in the new journal One Earth analyzed 50 years of data on 18 kinds […]

January 2020 was the warmest January on record for the globe

13 February 2020 (NCEI) – The globally averaged temperature departure from average over land and ocean surfaces for January 2020 was the highest for the month of January in the 141-year NOAA global temperature dataset record, which dates back to 1880. This monthly summary, developed by scientists at NOAA National Centers for Environmental Information, is […]

Map showing climate risk by country, 2017. The climate risk of each country is based on its ND-GAIN Index score for 2017. The ND-GAIN Index is a composite measure, with a range of 0-100, of a country’s vulnerability to climate change and its readiness to improve resilience. Vulnerability is quantified by the level of exposure, sensitivity and adaptive capacity of six life-supporting sectors (food, water, health, ecosystem services, human habitat and infrastructure). Readiness measures a country’s ability to realize adaptive actions in the economic, governance and social spheres.

U.N. warns that runaway inequality is destabilizing the world’s democracies – “Efforts to reduce inequality will inevitably challenge the interests of certain individuals and groups. At their core, they affect the balance of power.”

By Christopher Ingraham 11 February 2020 (The Washington Post) – Runaway inequality is eroding trust in democratic societies and paving the way for authoritarian and nativist regimes to take root, according to a dire new report from the United Nations. The findings note that solutions — including robust social safety nets, an active redistribution of wealth and […]

Image of the Day: Antarctica melts under its hottest days on record

By Kasha Patel 21 February 2020 (NASA) – On 6 February 2020, weather stations recorded the hottest temperature on record for Antarctica. Thermometers at the Esperanza Base on the northern tip of the Antarctic Peninsula reached 18.3°C (64.9°F)—around the same temperature as Los Angeles that day. The warm spell caused widespread melting on nearby glaciers. The warm […]
