In reading the article "Undies demonstrate a fun way to learn science," I just had to make a comment to those pushing cap and trade/climate control. Please read paragraphs 3 and 4 of that article.
Seems to me, in early school years, it was taught that carbon was necessary for plant life. Researchers and scientists have repeatedly affirmed that car emissions, etc., are not causing global warming/climate change.
It is a normal cyclical occurrence.
It appears that blocks to the truth refuse to be removed.
