My Dad...


I want to introduce you to my dad.

His name was Herman but went by his middle name, Leroy.

He's a fantastic father who always put his family first.

He's been gone for more than a decade but I still feel his presence...daily.

I hope to be as great a father to my kids as he was to his.

I can't imagine it being easy but I know I can do it!

He still loves me!

Thanks Dad!!!

Global Warming is Natural


There have been many ice ages in Earth's history.

Here is a chart that shows average global temperatures over the last 2 billion years. http://www.scotese.com/climate.htm During the Ice House periods the earth's climate could have been described as an ice age. There have been at least 4 major Ice House periods, but even within these there were cycles of colder and warmer climate. There is ample evidence to support these cycles of glaciation. There are a number of factors that affect Earth's climate.


The major factor that changes climate over time has been the pattern created by the variation in the Earth's orbit around the sun. The Earth changes in its distance from the sun and in its orientation to the sun as it orbits the sun. The three major variations are called eccentricity, obliquity, and precession. They produce cycles in climate that are on 400,000 years, 100,000 years, 41,000 years, and 19-23,000 year frequencies. As the earth moves further away from the sun, ice ages are initiated and continue until the earth has moved back towards the sun. To see some diagrams of these orbital cycles of Earth check these websites: http://www.uwsp.edu/geO/faculty/lemke/geol370/lecture_notes/16_causes_of_climatic_change.html and http://deschutes.gso.uri.edu/~rutherfo/milankovitch.html


So, even though I agree with taking steps to make the atmosphere a cleaner air to breathe, avoiding the highs and lows that this planet has gone thru and will continue to go thru, is unavoidable.


'nuf said! Have a great day!!!
