...Well it depends on whether you wish to believe what you read... In general, almost every article I see suggests that cold is a much worse problem than heat. To all aspects of life.
The perceived imminent heat problems are generally limited to tropical diseases (malaria, etc) where the link is stronger to wealth and public health instead of location, etc.
Are we talking about climate changes and weather systems and how it is threatening our habitat?
If yes, I have not come across article that say we are experiencing a colder weather globally. I only have the chance to read about global warming and its catastrophic consequences on living beings.
If you are talking about the preferred living conditions and health conditions in cold and hot regions, then I think I am off topic
By the way, I have heard people sharing habitat with the polar bears, but have not read about people living in Sahara desert.
