Just read that due to climate change, hotter than normal temps may be the new normal. In 2013, temps screamed up to 122 F. in Australia, which is frightening. But when you think about who really has the capacity to change this -- which is each individual -- it gets even more frightening. The primary cause of climate change is just too many people, full stop. I do not have much hope that people will stop procreating to save themselves, and this is the biggest tragedy of all.
