Hot dry summer, warm wet autumn

The hot dry summer is over, and warm autumn begins. Last year we had a wet warm winter. Seasons are changing, hot dry humid summers with wet warmer winters or colder. As temperature increases, heatwaves become common. The climate models show possible consequences but not everything. Once in a lifetime, extreme weather events are becoming more common. Volatility in the climate system has far-reaching impacts. Less water means lower rivers that impact shipping routes, higher sea levels mean ports need to move. The security of water and food comes into question rather quickly. 

The most obvious example is food crops, irregular rain means lower yields or floods or ruined farmland. Long periods of dry conditions are also a threat, the result is irrigation. With less water supply that causes a huge strain on what can be produced and how much. Suddenly water pollution looks rather important to and health of the water cycle. Everybody would need to use less water when water scarcity comes into question.  Humanity will have to adapt, be more efficient, find resistance crops or grow something else. A solution may be growing mixed fields over a single use. Old farming methods may be the answer. Tightly packed greenhouses use less water with a lower overall footprint could be the answer. Meat production requires livestock feed, less of that means less meat can be produced.

What worries me is nobody concerned about the scarcity of resources.
