As far as this historic period is concerned, the reconstruction of past temperatures based on deep boreholes in deep permafrost is one of the best past temperature proxies we have (for the global regions with permafrost — polar regions and mountainous regions)-- as a signal of average temperatures it's even more accurate than historic direct measurements of the air temperature, since the earth's upper crust acts as a near perfect conservator of past temperatures — given that no water circulation takes place, which is precisely the case in permafrost where by definition the water is frozen.

The solutions they considered were: setting up a rural water supply program providing poor communities in Africa with deep boreholes and public hand pumps; developing campaigns that raise awareness of disease transmission, health costs, and the social benefits of sanitation; ensuring affected communities have access to technology to remove contaminants in raw water supplies; building reservoirs in some parts of Africa, such as the sparsely inhabited Blue Nile gorge in Ethiopia.
