Acting like Neanderthals

In modern times we know that the Earth is warming and most of us accept the blame lies squarely with ourselves. We release gasses from burning fossil fuels that slowly but surely build up in the atmosphere to trap more and more heat. Glaciers are melting, sea levels are rising and already creatures are becoming extinct. Yet this is not the first time the Earth has faced such changes. In the past, climate change may have been entirely natural but the ramifications of a rapidly warming planet were much the same, including the extinction of species. Except that, long ago, among the species that disappeared were archaic humans – Neanderthals. Could the same ever happen to us?
