This article on Food & Wine reports on predictions by Sam Kass, a former White House chef.

I wouldn't normally rate a White House chef as an expert on this subject, but he was also the White House's first-ever senior adviser on nutrition, and he quotes some sources for his predictions that I do consider expert. These experts are saying that there could be significant shortages of:

• Coffee, with many growers being forced to replace arabica with robusta coffee plants (so, worse coffee);
• Cashews;
• Avocados;
• Wine;
• Chocolate;
• Shellfish;
• And rice.

These crops are all under threat by climate change.

I can add to the above list, with:

• Almonds, with much of the world supply grown in areas of California with drastic water shortages (also due, in part, to climate change, but also by bad water management);
• Olives (and therefore olive oil), where trees are being blighted by a virus which is drastically reducing crops in Italy, Corsica and Spain, and in Greece where orchards are being infected by another virus.

There is not a single item listed above that I do not consume, and shortages and the resulting price rises will impact my diet, my quality of life and my bank balance. I imagine that most readers will be similarly affected.
