WMO Greenhouse Gas Bulletin (GHG Bulletin) - No.15: The State of Greenhouse Gases in the Atmosphere Based on Global Observations through 2018
Measurements of the content of radiocarbon (14C) in atmospheric carbon dioxide (CO2) provide a unique way to discriminate between fossil fuel combustion and natural sources of CO2. Simultaneous observations of CO2 and 14C demonstrate the decline of 14C content in atmospheric CO2 caused by CO2 addition from fossil fuel combustion. This finding illustrates the importance of long-term measurements of atmospheric composition by laboratories involved in the WMO Global Atmosphere Watch (GAW) Programme in helping identify greenhouse gas emission sources.

Guidance on Environmental Flows : Integrating E-flow Science with Fluvial Geomorphology to Maintain Ecosystem Services
Fluvial systems provide a wide range of necessary services for human society to thrive on. These are the so-called ecosystem services: food, drinking water, natural flood mitigation, energy and so forth. Such services are linked to an appropriate level of functionality of fluvial processes, which can be accounted for in terms of ecological objectives. These ecological objectives in watercourses can be reached only if appropriate flow and sediment regimes and related quality of channel morphology are guaranteed. The establishment and maintenance of such flow regimes, namely environmental flows ...

WMO Greenhouse Gas Bulletin (GHG Bulletin) - No.14: The State of Greenhouse Gases in the Atmosphere Based on Global Observations through 2017
The latest analysis of observations from the WMO GAW Programme shows that globally averaged surface mole fractions(1) calculated from this in situ network for carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) reached new highs in 2017, with CO2 at 405.5 ± 0.1 ppm(2), CH4 at 1859 ± 2 ppb(3) and N2O at 329.9 ± 0.1 ppb. These values constitute, respectively, 146%, 257% and 122% of pre-industrial (before 1750) levels. The increase in CO2 from 2016 to 2017 was smaller than that observed from 2015 to 2016 and practically equal to the average growth rate over the last decade. The influence ...
