Another Cold Wave

Yet another cold wave hits Dallas, and I guess this time the precipitation point has not yet reached, so its all in rain and wind and temperatures in the -'ve celsius ranges...If you stay outside for a minute, you will be frozen to death. Dallas is supposed to be one of the hottest places in Texas (of course its winter now), but off late when I hear news like "It snowed in UAE", "Saudi Arabia has been getting too much rain in 2004" makes me think how close we are towards our own destruction due to Global Warming!!!!!!
