Yes, the last decade has been 1 degree warmer, however, this could also just be a temprature flucuation. From decade to decade, even year to year, tempratures tend to flucuate. To get a more accurate picture of how much temprature has actually changed you would need a much larger sample. The media uses the 1 degree in the last year to help heighten awareness. Yes its happening. but we must look at the whole picture. Think of how much you waist personally per week. Everything you by is wraped in plastic, which is a processed oil.. the process takes energy, trucks to deliver, ect. Its much more than a vehicle problem. Its a consumption problem. Turn off lights, carpool, get paper bas instead of plastic, recycle your plastic. Lots of things can be done, the simple fact is a small percent of the population is willing to try.
