Lesson 13: Personal Examples of Climate Change
The climate changes. It's what it does. We just learned this week about how the Earth has gone through many hot and cold shifts. Through ice cores, fossil pollen, tree rings, and other proxy data, scientists have concluded this much and the evidence for it is increasing.This graph to the right illustrates their findings. It shows the estimated average global temperature differences over the last 8 million years. You can see there has been times where the average temperature was much lower, and times where it is much higher. For us, we are in a time where the average global temperature is rising. While human processes may be causing this process to quicken, it is part of a natural cycle of heating and cooling. I can't say that I've seen noticeable changes in my lifetime as far as heat go, but this was a really cool website where you can look up temperature trends in your country, state, or even region. https://www.ncdc.noaa.gov/cag/time-series/us/10/9/tavg/ytd/12/1967-
