As a rising global population and increasing standard of living drive demand for freshwater......the only reason anyone reports about global thirst is to push the AGW agenda, rather than to actually save lives.
The sentence you quoted was talking about increasing population and standard of living. Neither of those mentions global warming. If large quantities of the oceans were to be converted to fresh water, we’d have deserts blooming, many more plants & food growing, converting CO2. Basically global warming would be a quirky thing of the past, like our ancestors worrying about not getting enough calories to survive winter.
