"Sub-Saharan Africa had the highest cold-related excess death rate"<p>That's an interesting choice. It conflates cold-related excess deaths in the equatorial lowlands (which struggle to ever get below 70F/20C) and the southern highlands (like Lesotho, which routinely goes below freezing in June/July). Both are sub-saharan.<p>Of course, that may just be a bad summary, but it puts it onto the "should probably verify the results before I trust it" pile of papers, something that's sadly growing at an ever-increasing pace.
