30 May 2018 (NOAA) – NOAA’s Annual Greenhouse Gas Index (AGGI), which tracks the warming influence of long-lived greenhouse gases, has increased by 41 percent from 1990 to 2017, up 1 percent from 2016 — with most of that attributable to rising carbon dioxide levels, according to NOAA climate scientists.

By Josh Gabbatiss 3 February 2018 (The Independent) – Toxic nitrogen dioxide emissions around major ports and sea routes in the UK are four times higher than previously suggested, according to a report for the Government. Levels of sulphur dioxide, another harmful pollutant, are three times higher. Experts say shipping pollutants, which are concentrated around […]
4 January 2018 (Smithsonian Environmental Research Center) – In the past 50 years, the amount of water in the open ocean with zero oxygen has gone up more than fourfold. In coastal water bodies, including estuaries and seas, low-oxygen sites have increased more than 10-fold since 1950. Scientists expect oxygen to continue dropping even outside […]
4 January 2018 (SERC) – In the past 50 years, the amount of water in the open ocean with zero oxygen has gone up more than fourfold. In coastal water bodies, including estuaries and seas, low-oxygen sites have increased more than 10-fold since 1950. Scientists expect oxygen to continue dropping even outside these zones as […]
30 October 2017 (WMO) – Concentrations of carbon dioxide in the atmosphere surged at a record-breaking speed in 2016 to the highest level in 800 000 years, according to the World Meteorological Organization’s Greenhouse Gas Bulletin. The abrupt changes in the atmosphere witnessed in the past 70 years are without precedent.Globally averaged concentrations of CO2 […]
By Sam Lemonick 17 October 2017 (Forbes) – A years-long study of Minnesota farm fields has found that emissions of nitrous oxide—a more dangerous greenhouse gas than carbon dioxide—will likely increase as our planet gets warmer. And our climate models aren’t ready.Like carbon dioxide, nitrous oxide (yes, the same stuff as laughing gas) traps heat […]
By Tim Schröder 3 August 2017(Helmholtz-Zentrum Geesthacht) – Nitrogen compounds are an important factor in the production of algal biomass. The team led by biologist Kirstin Dähnke from the Institute of Coastal Research at the Helmholtz-Zentrum Geesthacht has been carrying out extensive Elbe nitrogen measurements for this reason.These measurements have shown that regions upstream from […]
12 August 2017 (AFP) – The Earth set a series of dire records in 2016, including hottest year in modern times, highest sea level and most heat-trapping gases ever emitted, a global climate report said yesterday. A range of key climate and weather indicators show the planet is growing increasingly warm, a trend that shows […]
By Matt McGrath 7 August 2017 (BBC News) – Potent, climate warming gases are being emitted into the atmosphere but are not being recorded in official inventories, a BBC investigation has found. Air monitors in Switzerland have detected large quantities of one gas coming from a location in Italy. However, the Italian submission to the […]
11 July 2017 (NOAA) – NOAA’s Annual Greenhouse Gas Index, which tracks the warming influence of long-lived greenhouse gases, has increased by 40 percent from 1990 to 2016 — with most of that attributable to rising carbon dioxide levels, according to NOAA climate scientists.
