Al's Rantings

A view of the world from a hillbilly perspective.

Location: Virginia

I was born and went to school in the heart of the Appalachian mountains, in southern West Virginia. After graduating from college, I got married, and began working in Bristol, TN. I have have various jobs from Tennessee to up state New York and a few points between. Now I work in West Virginia. Some day, I want to live in Alaska.

Global Warming...

Well its definite. According to the Roanoke Times the "Study of tiny air bubbles in the ice confirm that current levels of CO2 are higher than anything experienced at least in the last 650,000 years." And "There can be no serious, reasonable doubt that this unprecedented increase is due to industrial activity that dumps billions of tons of greenhouse gases into the atmosphere every year."

But not all scientist agree. Look here at a report released by the National Center for Policy Analysis. This reports concludes "The Earth currently is experiencing a warming trend, but there is scientific evidence that human activities have little to do with it. Instead, the warming seems to be part of a 1,500-year cycle (plus or minus 500 years) of moderate temperature swings."

The authors did not look at a single item, instead "Evidence of the global nature of the 1,500-year climate cycles includes very long-term proxies for temperature change — ice cores, seabed and lake sediments, and fossils of pollen grains and tiny sea creatures. There are also shorter-term proxies — cave stalagmites, tree rings from trees both living and buried,
boreholes and a wide variety of other temperature proxies."

"Is the Earth currently experiencing a warming trend? Yes. Are human activities, including the burning of fossil fuel and forest conversion, the primary — or even significant — drivers of this current temperature trend? The scientifically appropriate answer — cautious and conforming
to the known facts — is: probably not."

Why? Because "During the past 20 years, scientists have been accumulating
strong physical evidence that the Earth consistently goes through a climate cycle marked by alternating warmer and cooler periods over 1,500 years (plus or minus 500 years)."

The earth goes through cycles. Not everyone agrees with the Roanoke Times about global warming. By the way, this report "The Physical Evidence of Earth’s Unstoppable 1,500-Year Climate Cycle" was released in September 2005.
