Saudi authorities have installed air-conditioned shelters and other cooling methods. But these are only available to pilgrims with official permits. Most of those who died did not have permits, meaning they could not access cool relief.
This is absolutely devastating, there's absolutely no doubt. When reading the article, though, I didn't understand why this is an article in this particular community. Maybe Saudi Arabia should provide more cooling methods, or not let too many people in?
Although climate change is, of course, caused by Western-style capitalism, it is by far not the only reason. China, a socialist country, is the world's largest coal producer and importer, and coal likely remains the bedrock of China's energy system for at least another decade.
I feel this is a well-researched article, but maybe the wrong community?
