A presentation prepared to focus on the localized weather change. Also an effort to help people working in field/sites (like I) by showing that the amount of physical work on site/fields and effort that was put a decade ago [as constantly reminded by some of the seniors we are working with ;) ] cannot be expected in this situation anymore. Either efficiency/work or health/safety will have to be compromised. I'd prefer amount of work to be compromised. Yeah, sure, the obvious answer is, recruit more people, create more teams.
