Today the World Meteorological Agency @WMO held a press conference in the lead up to the COP26 summit, which addressed water, and the importance of measures to address adaptation measures. media.un.org/en/asset/k17/k…

@WMO A new report has been issued which contains some very interesting slides on changes in climate so far (last 20 years) plus what is expected to happen.

In the above slide you can see now very clearly that Sub-Saharan Africa (particularly the Sahel & East Africa) and the Middle East are expected to get substantially wetter as the climate warms, while South America is expected to get drier.

These two slides try to quantify the amount of damage that is being done already by global warming. In terms of economic damage. Bear in mind that damage in poorer countries in numeric terms is understated due to its economic costs being numerically lower.

This slide locates particular areas which are already stressed due to climate change in terms of water availability.

These two slides address the core area of business of the @WMO forecasting, data and early warning systems.

@WMO The WMO's Prof. Petteri Taalas informed the conference that COP26 is going to include announcement of significant investment in improving forecasting, data and early warning systems for the developed world - as this is a particularly important need in climate adaptation.

@WMO Finally here are WMO's recommendations from their report. [Prof. Taalas is the Secretary-General of the WMO]

Maxx Dilley, Director, Climate Services Dept of WMO emphasised the need for better information about the benefits of better forecasting on outcomes.

P.S. FWIW: I have some doubts about this part of the accepted climate prediction narrative - Reduced precipitation in the Tropical Atlantic and the Mediterranean. It seems counter-intuitive, and its not what we are currently seeing.
