I am especially gratefull dear Mark for your focus on the risks, for the poorest. Overall; the absurdity in the midst of both - so many people more wealthy than ever before plus the hunegr alarms, and the climate beating records; to be beaten. We are I N the beginning of a global climateemergergency; and by now over 2 5 0 0 0 0 people evacuated in Spain and france; crops and wildlife lost each second... Yet still. ... Well. Earth Science and I declare CLIMATEEMERGENCY ! Ill share the part with the risks here, and join everyone who cares. : https://www.facebook.com/profile.php?id=61565699637497

The real problem is not ElNinio, but the fact that sufficient food stocks are not created as security for crises. A large volcanic eruption, like Krakatoa, could easily lead to a 50% crop loss in the following two years. And at some point something like this will happen again. It would cost just 1% of the gross national product if one were to build up a grain supply spread over 10 years that could feed everyone for a year (around 400 kg/person). We currently rely on derivatives and global trade to hedge risk. This can cushion small crises quite well. But since fewer reserves are held, this makes a major loss of production that much worse. And the world itself can produce more than enough food. But in agriculture the response time is typically at least a year! Therefore, you should take appropriate precautions. And then you can easily absorb regular events like ElNinio.
