Drought and Water Scarcity (WMO-No. 1284)
World Meteorological Organization (WMO) ; IDMP expert panel with 14 experts from various IDMP partner organizations including UNCCD and FAO - WMO, 2022Driven by climate change, population growth, economic development, and poor water management, the increasingly limited availability of freshwater resources is a fundamental concern for societies worldwide. Drought and water scarcity – two major phenomena that challenge water security – know no national boundaries and affect all socioeconomic sectors of society, with a greater impact on the more vulnerable, poorer or marginalized populations.

World Meteorological Organization (WMO) ; IDMP expert panel with 14 experts from various IDMP partner organizations including UNCCD and FAO
Published by: WMO ; 2022Driven by climate change, population growth, economic development, and poor water management, the increasingly limited availability of freshwater resources is a fundamental concern for societies worldwide. Drought and water scarcity – two major phenomena that challenge water security – know no national boundaries and affect all socioeconomic sectors of society, with a greater impact on the more vulnerable, poorer or marginalized populations.
Drought is a natural climatic feature of below-average precipitation, which can last for months or years, while water scarcity results from a long-term, human-induced imbalance between water demand and supply.
Drought and water scarcity are often interrelated, and droughts can trigger or amplify water scarcity, while water scarcity can aggravate droughts.
This publication highlights the differences between drought and water scarcity and where they become blurred due to climate change and human activities. Coping strategies to both phenomena should be part of overall integrated drought and water resource management strategies.Language(s): English

WMO Guidelines on Multi-hazard Impact-based Forecast and Warning Services (WMO-No. 1150), Part II: Putting Multi-Hazard IBFWS into Practice
This publication, 1150 Part II follows WMO-No. 1150, Part I which was published in 2015. In the intervening years, as many NMHSs and their partner agencies developed impact-based forecast and warning services (IBFWS), understanding, experience and knowledge in this area has developed and grown significantly. The material presented in this “1150 Part II” seeks to distil and summarise that knowledge and to provide examples of good practices in IBFWS, illustrating and augmenting the insights contained in the original guidelines.

This Bulletin represents the latest analysis of observations from the WMO GAW Programme. It shows globally averaged surface mole fractions for carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) and compares them with the mole fractions during the previous year and with the preindustrial levels. It also provides insights on the change in radiative forcing by long-lived GHGs (LLGHGs) and contribution of individual gases to this increase.

Report on the Unexpected Emissions of CFC-11 (WMO-No. 1268)
The Report was written by the Scientific Assessment Panel to the Montreal Protocol on Substances that Deplete the Ozone Layer. CFC-11 (CCl3F) was reportedly fully controlled under the Montreal Protocol since 2010. However, a 2018 scientific paper revealed that instead of decreasing, CFC-11 emissions were increasing. In reaction, the Protocol parties agreed to Decision XXX/3: Unexpected emissions of trichlorofluoromethane (CFC-11). This Report addresses: current and past observations of CFC-11 atmospheric abundances; information on the CFC-11 global and regional emission increase and subsequent ...

WMO Open Consultative Platform White Paper #1 - Future of weather and climate forecasting
The demand for weather and climate forecast information in support of critical decision-making has grown rapidly during the last decade, and will grow even faster in the coming years. Great advances have been made in the utilization of predictions in many areas of human activities. Nevertheless, further improvements in accuracy and precision, higher spatial and temporal resolution, and better description of uncertainty are needed for realizing the full potential of forecasts as enablers of a new level of weather and climate-informed decision-making.

2020 State of Climate Services: Risk Information and Early Warning Systems
Between 1970 and 2019, 79% of disasters worldwide involved weather, water, and climate-related hazards. These disasters accounted for 56% of deaths and 75% of economic losses from disasters associated with natural hazards reported during that period. As climate change continues to threaten human lives, ecosystems and economies, risk information and early warning systems (EWS) are increasingly seen as key for reducing these impacts. The majority of countries, including 88% of least developed countries and small island states, that submitted their Nationally Determined Contributions (NDCs) to UN ...
