It's damn hot in Texas

It is damn hot today. Hot enough to break a record in the temperature books for Dallas/Fort Worth, as well as many other places in Texas. Yesterday too. One hundred degress farenheight in mid-April. Already, just 3 1/2 months into 2006, we have experienced at least 6 record high temperature days.
If wonder if anyone is bothering to ask the simple question, why? Why is it so damn hot? What if it gets hotter this summer?
Unless you're a shill for the oil industry or a blind follower of our messianic president or enamored of Michael Crichton's Cartesian doubt on global warming, you might consider the topic of increased CO2 and other greenhouse gases in our atmosphere contributing to temperature extremes.
It's too bad our society has no concept of science to understand how greenhouses work, and the principles of global warming that are inevitable when we raise concentrations of greenhouse gases in our atmosphere.
Will it take more and more human deaths as a consequence of extreme weather for us to wake up to this reality?
