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.
Drought is a natural climatic feature of below-average precipitation, which can last for months or years, while water scarcity results from a long- ...

GAW Report, 226. Coupled Chemistry-Meteorology/ Climate Modelling (CCMM): status and relevance for numerical weather prediction, atmospheric pollution and climate research
Online coupled meteorology atmospheric chemistry models have undergone a rapid evolution in recent years. Although mainly developed by the air quality modelling community, these models are also of interest for numerical weather prediction and climate modelling as they can consider not only the effects of meteorology on air quality, but also the potentially important effects of atmospheric composition on weather. This report provides the main conclusions from the Symposium on “Coupled Chemistry-Meteorology/Climate Modelling: Status and Relevance for Numerical Weather Prediction, Air Quality and ...
WCDMP, 84. Eighth Seminar for Homogenization and Quality Control in Climatological Databases and Third Conference on Spatial Interpolation Techniques in Climatology and Meteorology
The 8th Homogenization Seminar and the 3rd Conference on Spatial Interpolation were organized together considering certain theoretical and practical respects. Theoretically there is a strong connection between these topics since the homogenization and quality control procedures need spatial statistics and interpolation techniques for spatial comparison of data. On the other hand the spatial interpolation procedures (e.g. gridding) need homogeneous data series with high quality. Practically the CARPATCLIM project that was launched in 2010 and ended in 2013 is a good example for this problem. Th ...

Attribution of Weather and Climate-Related Extreme Events
Unusual or extreme weather and climate-related events are of great public concern and interest, yet there are often conflicting messages from scientists about whether such events can be linked to climate change. There is clear evidence that climate has changed as a result of human-induced greenhouse gas emissions, and that across the globe some aspects of extremes have changed as a result. But this does not imply that the probability of occurrence (or, given a fixed damage, risk) of a specific type of recently observed weather or climate event has changed significantly as a result of human in ...

Global sea-level rise update
Sea level is higher now and is rising much more rapidly than at any other time in the past 3 000 years. We know that sea level will continue to rise for many centuries, even after global temperatures are stabilized, as it takes that long for the ocean and ice sheets to respond fully to a warmer climate. Unchecked global warming is likely to raise sea level by several metres in coming centuries, leading to the loss of many coastal cities and entire island states. This longer-term threat is already being exacerbated by increased frequency of short-term extreme sea levels due to the superposition ...
Role of NMHSs in adaptation to climate variability and change : (Analysis report of a survey)

WCRP, 132. SPARC Report on the Evaluation of Chemistry-Climate Models
Three-dimensional climate models with a fully interactive representation of stratospheric ozone chemistry otherwise known as stratosphere-resolving chemistry-climate models (CCMs) are key tools for the attribution and prediction of stratospheric ozone changes arising from the combined effects of changes in the amounts of greenhouse gases (GHG) and ozone-depleting substances (ODS). These models can also be used to infer potential effects of stratospheric changes on the climate of the troposphere. In order to know how much confidence can be placed in the results from the CCMs, both individually ...
