Climate Change Today
During the previous post, we discussed the major role that human activities, fossil fuels, and the associated carbon dioxide emissions play in the climate change being observed today. Now, you may look back at my last few posts and say, well the climate has changed for the Earth’s entire existence naturally, so the climate should continue…

Earth: The “Present” Day
In the previous posts, we discussed the climatic events that led to the rise of human civilization some 10,000-7,000 years ago. During the times prior to 20,000 years ago (when the last glaciers receded from North America), there have been several major swings in climate, allowing for many regions of life to become extinct. While these…

Earth: 360 Million – 250 Years Ago
At the end of the last discussion, we established the hot, flourishing world of the Devonian period. During that time, we saw life completely transform. I also mentioned that there was an event that brought the world out of this hotter period, which allowed for yet another extinction event. During this post, we will start off…

Earth: 720-360 Million Years Ago
In the previous post, we discussed the initiation of Earth’s atmosphere, and the first formation of life. We learned how microscopic life managed to extremely change the climate by altering the amount of greenhouse gases in the atmosphere. As a result, Earth entered its first ice age known as the Huronian, which was followed by…

Earth’s Early Atmosphere
As I discussed in my previous post, the Earth’s climate is not only changing today, but it has changed for billions of years and will probably continue to do so long after us humans are gone. Generally, Earth’s climate history shows that dramatic swings in climate occur over the course of tens of thousands, to millions…

Climate Change and Geologic Time: We Are Speeding the Process
-Imagine Life Five Years Ago… I know for me this seems like such a long-time ago. It may be the fact that I was preparing to enter my sophomore year in high school; a crucial point in trying to figure out what to do with my life. It may be the fact that back then,…
