On the Las Vegas Temperature Increases

Yes, the average temperature in Las Vegas has gone up. But what these loathsome alarmists never reveal is that the increases have almost exclusively been obtained at night (http://wattsupwiththat.com/2014/06/24/why-would-climate-skeptics-hold-a-conference-in-hot-las-vegas/), MEANING that the increase is almost guaranteed to be a product of urbanization (Las Vegas being one of the faster growing cities in the country) and NOT CO2. HELLO!!!
