World Meteorological Organization (WMO) ; United Nations Educational, Scientific and Cultural Organization (UNESCO); Intergovernmental Oceanographic Commission (IOC); et al. - WMO, 2018The Paris Agreement will drive climate policy for many years to come. It establishes a science-based cycle of reporting (through the Transparency Framework), assessment (the Global Stocktake) and increasing ambition of action to address climate change (Nationally Determined Contributions, NDC). The Agreement has three main aims: to limit the global temperature increase, to increase the adaptive capabilities of the Parties, and to increase the making finance flows consistent with a pathway towards low greenhouse gas emissions and climate-resilient development.
The Paris Agreement covers ...
Understanding the IPCC Special Report on 1.5°C
In 2015 governments adopted the Paris Agreement to tackle climate change (see below) and invited the IPCC to prepare a special report in 2018 to assess the impacts and related pathways of warming of 1.5ºC. This brief provides context and explanation of key concepts for policymakers, media and others about the Special Report on 1.5°C, scheduled to be published, subject to approval, by the Intergovernmental Panel on Climate Change (IPCC) on 8 October 2018. This brief is produced prior to the release of the report and therefore does not contain results from the report itself.

GESAMP - Reports and Studies, 97. The magnitude and impacts of anthropogenic atmospheric nitrogen inputs to the ocean
World Meteorological Organization (WMO) ; Food and Agriculture Organization (FAO); United Nations Educational, Scientific and Cultural Organization (UNESCO); et al. - WMO, 2018The present global modelling study of the Nr atmospheric cycle and Nr deposition to the ocean is the first that evaluates past, present and future Nr atmospheric deposition accounting for ON primary sources as well as for secondary ON chemical formation as a N-dependent process. While the total Nr deposition to the ocean is not expected to change significantly by 2050, the relative importance of oxidized and reduced N is expected to change, with an increasing proportion of ammonium compared to nitrate, resulting from more efficient controls on terrestrial emissions of nitrogen oxides (NOx) com ...
