Not all energy is heat. I think that's a problem with expressing the change in degrees Celsius. Wind velocity is another factor of increased energy in the climate that contributes to lower temperatures (wind chill). That's why scientists have been trying to make sure people call it "global climate change" rather than "global warming" because not all energy is heat and we need to stop giving the false impression that everything is just going to be hotter: more energy in the system will cause a lot of side effects that aren't just increased heat.

I think the lack of uniformity is a big part of many peoples' climate skepticism. Certainly it is a talking point. It seems like many people have too little imagination to comprehend climate science, much less the appetite to learn something inconvenient.
