From an archeological point of view, we know that there have been civilizations that have arisen, only to parish from the climate changes. One example of this is the Fremont Culture that existed almost 2,000 years ago in North America's southwest region, whose eventual outcome was favored by a climactic shift that occurred around 800 CE. As the weather changed due to this climactic shift, the staple crops that were grown for food became more abundant. This abundance was brought on by the number of crops that actually survived becoming greater creating higher yields, due to a change in the weather patterns. From a greater abundance in food, brought on by greater harvests, the Fremont people were able to become more sedentary. There was a rise in population and population density among the people who lived by the Fremont way of life. As the climate changed, the culture changed as well. The Fremont people, whose way of life had gone on for centuries, became a precursor to the great Anasazi Culture, that produced what could be the finest examples of ancient Native American architecture and fine art ever known in North America. Yet, sadly, after only several hundreds of years of progress brought on by a favorable climate, their culture declined due to another climactic shift, one that returned the weather patterns to what they had been during the era when the Fremont Culture existed. As the dry and arid lands yielded less, populations declined and the political stability among the Anasazi's dense population centers might have fallen apart. As food became more scarce, the competition for resources probably also brought attacks from outside groups trying to seize the resources of the people who lived in those larger population centers. With the weather slowly changing back to being hot and inhospitable, we know from the architecture that remains that locations of cities and towns shift toward environments that are more safe and secure as well ones that favor greater crop abundance or have a continual source of water.
Will we as a planetary culture, be able to manage the resources available to us as climate change becomes a crisis for us all? Will the world civilization that we know today fail to achieve success and survive the new climate change that we are seeing? All of these question and more pop up as I think of the climate crisis and the long strange summer it's been. However, with summer over in North America, I for one cannot wait to see what the winter holds for us. Is there any greater crisis in our lives than the climate crisis? We'll just have to wait and see what the future holds.
