Global warming may seem to some people like just a little recycle symbol on your water bottle or some blue bins, but really global warming is a global event that is occurring as I write this. Everyday our environment becomes warmer and warmer and is at its warmest point today than it has been in the past four thousand years. It has been recently predicted that our earth is getting so warm that in the next few decades it will become the hottest temperature levels ever seen on earth. Unfortunately, even with the lowest possible human activity we could do, the temperature will still increase and be warmer than hottest time of the Holocene, or the modern geological era. Scientists like Shaun Marcott of Oregon State University and other earth scientists, have studied the global temperatures over the past nearly 10,000 years, nearly the whole Holocene period. The climate change of earth is not all because of human as the temperature depends on the distribution of sunlight, the earths orbit and other events that have happened in the past and are out of our reach. However, we are definitely to blame for a portion of global warming. Interestingly, without humans the Northern Hemisphere probably would have frozen over in the next few thousand years but the large amounts of greenhouse gases from people might stop that. However, graphs of the climate change that scientists are studying show that the modern rise has recreated old temperatures and on the time scale, temperatures like in the Holocene time are expected to be felt again. Even though there are geological affects on global warming, humans still have their part. You should still recycle your bottles and take care to follow all of the rules we now have had hammered into us for years, such as walking when you can to avoid gas and using public transportation, because what you do, no matter how little for climate change, can still matter.
Life is affected by global warming and how global temperatures are rising and are at their heights since thousands of years in the past is frightening. With high climate change comes struggle for life as plants and other types of species will be injured from the changes in temperature. Also mentioned in the article is how past climate changes have been steady and slow allowing different organisms to evolve and adjust to the new climates, but the new changes in temperature expected will be fast and put tension on numerous species including humans as we are a part of nature as well. Plants and animals we eat or use for food goods or other material might die out due to these severe changes in climate and ultimately there is no good to come out of these fast climate changes.
I found the article to be fairly clear and concise which I praise. It is definitely hard for a scientist or someone who is familiar with a scientific study to put it into terms the every day person could understand as you need to put it into words that make sense and also make sure the topic makes sense. This article mostly did this well as I was able to follow along with the article and understand what it was talking abut but eventually the article moved too quickly and started jumping around with what it was talking about. An example of this is when it mentions the Northern Hemisphere and how it is destined to freeze over again, which seems like a very big topic someone could study for years and is just passed by in a few sentences. I feel like the author should have elaborated more on this as well as when the article mentioned at the end how life would be affected. I feel the biggest reason why most people would stop and read this article is because they know it will affect life and change our environment and this article really only mentions that as an afterthought which somewhat leaves the reader hanging.
