Climate Change

Open Email to Sen. Cruz (TX):

Dear Sen. Cruz,
I have read your form letter on climate change.
  You say you are opposed to the proposals of President Obama, the Environmental Protection Agency (EPA), and some in Congress to limit greenhouse gases without regard to jobs and the economy.
Congratulations on being partially correct. However, you appear to be confused on greenhouse gases and climate change.
Carbon dioxide has been called a greenhouse gas and limitations on its submission to the atmosphere from the burning of carbon containing fuels, has been promoted.
The fact is that carbon dioxide is a greenhouse gas, as are also nitrogen and oxygen, which are major components of the atmosphere. We need greenhouse gases to control Earth temperatures in a range to support life. Carbon dioxide can be considered as an addition to that desirable outcome, but it's concentration in the atmosphere of only 0.05%, which makes its contribution insignificant. For those who want to look at it from a negative aspect of carbon dioxide increasing global temperatures, it is a ridiculous proposal, but it can be answered with the same fact that at 0.05% concentration, it has no significant effect on climate.
