The first class that I took which dove deeply into understanding climate change and its routes was AP Environmental Science my junior year of high school. I took that course in 2018 and have not taken many classes since that contain the same overlapping topics. Because it has been a few years since I learned deeply about the climate change, I focused my research for this blog post about how green house emissions have altered since then and whether or not climate change is reversible. In my readings, I learned that before the Paris Climate Agreement of 2014, it was expected that the Earth’s average temperature would increase by roughly 4.2* celsius by the end of the century would which would have proven to be catastrophic. However, with the advanced focus on saving our planet, the curve has shifted downwards in the last few years projecting a 3* increase, which still is dangerous but there is more room still for the curve to shrink. A huge reason for the positive trend in the temperature curve is due to the increasing availability of save and renewable energy sources such as electric cars, solar, and wind options. The worlds average ocean temperature is roughly 17* F which is one of the main sources of projecting the climate change curve. A shift in that temperature of even .25% either direction will reverse the positive shift in the curve. Water temperature as well as temperature on land again is all directly correlated to green house gas emissions and an abundance od CO2 in the atmosphere.
