Humans have been affecting the earth’s atmosphere for at least 2,000 years.
I was looking over Science Daily’s website and found so many articles about man’s involvement with global warming. It seems humans have affected the environment for thousands of years. The Little Ice Age and Medieval Warming period all the nay sayers like to brandish as proof that global warming happened before and is a natural occurrence just ain’t so.
Man has been affecting the environment for thousands of years. The sad thing is this article is almost 3 years old. Have these findings been censored from the general public because I’ve been arguing with people who have brought up the ice ages and warming periods of the past, while the whole time science has had proof that: “Humans have been tinkering with greenhouse gas levels in Earth’s atmosphere for at least 2,000 years and probably longer, according to a surprising new study of methane trapped in Antarctic ice cores conducted by an international research team.”
Read more about it and browse around because there is a plethora of articles and findings that substantiate we are indeed causing what we call global warming.
