GLOBAL WARMING!!!!!

hai take a look at the picture below.how true is this one.i just saw an advertisement recently.it was an ad for an ac.it said even if the temprature is 48 degrees outside ur room would be very cool.it is ofcourse true.but the same ac which keeps u cool would become a cause for the rise of the temprature in the earth.so the ad should go like this: even if it is 48 degrees outside ur room will be cool and after sometime the world would be hotter.
