According to evidence, is the climate changing right now?
- What does evidence say about humans’ roles in the changing climate?
- How is climate change likely to affect our society and our world?
The weather changes everyday. One day could be scorching, and the next day will have a light breeze, enough to make you wear a sweater. We know weather changes, but what about the global temperature of the earth?
According to the scientists at NASA's Goddard Institute for Space Studies the average global temperature from 1951-1980 was apporximately 57 degrees Fahrenheit. In the years that followed the global temperature rose. Global warming, a warming of the earth's global temperature, is a phenomena that can be scientifically attributed to human activities. According to studies done by the National Academy of Sciences and its affiliates, the global temperature has increased about 1.4 degrees Fahrenheit over the past 100 years, that increase was seen mostly in the past thirty years.
What has happened in the past thirty years? Let's take a look around the world. In the past thirty years the Chernobyl nuclear disaster took place, the first Gulf War occured, the release of Nelson Mandela, and the death of Michael Jackson. Quite and eventful 30 years. What has also occured is an increase in the burning of fossil fuels. The industrial revolution took place within the last three decades, and the Earth is having a negative reaction to industry.
Human activity, along with natural occurences, have caused a change in the permanent climate of the Earth.
This was a great blog that you did Sam. I agree that there is more usage in the burning of fossil fuels.
ReplyDeleteTotally in agreement. The nuts use of industry and fossil fuels are having quite a negative reaction. I am still sad that Riverside has one of the poorest air qualities...and I run in it all the time *insert whining here*.
