Several Decades Ago Science Warned Of 'Global Cooling'
Actually global cooling (which is not currently taking place) poses a real danger. Unlike global warming, global cooling would actually be something to worry about. Life can and has thrived in much hotter conditions than now. When the planet starts getting cold again (and there's no reason to think it won't someday) it will pose a serious danger. An Ice Age is always catastrophic. I lived in Nevada for years and even in the desert in120°F heat we grew lush gardens every summer. Nothing grew in winter.
