> If there is suddenly a shortage of water for irrigation, and of natural rainfall, most crops will fail. Are climate change scenarios predicting less rainfall

  That's a good point, and that's an area I don't understand. It's important to look at length of dry spells, which will kill crops, rather than just average precipitation.

    Anyway, it seems that for the time being the world is getting greener: https://www.thezip.org/wp-content/uploads/2019/07/20190722_115825.jpg https://www.thezip.org/wp-content/uploads/2019/07/20190722_1... Article: https://www.forbes.com/sites/trevornace/2019/02/28/nasa-says-earth-is-greener-today-than-20-years-ago-thanks-to-china-india/ https://www.forbes.com/sites/trevornace/2019/02/28/nasa-says... Some of it might be due to human intervention (India is mentioned in this sense) but much else obviously isn't: most of Siberia, Europe (especially souther Europe, Italy and Greece), Turkey, China and South & North Korea and Japan[1], the central US and Canada, and even Australia. [1] I stress these because the article claims the greening follows country borders and therefore it's due to active human intervention: in fact from the map it's clear that it doesn't, the whole pacific coast of Asia seems to be extremely greening.
