When did we switch from reporting the actual ambient air temperature to the heat index? I know why, it lets them post inflated temperatures to further the global warming agenda. I'm sure most people don't realize this and now think the temperature has taken a huge jump as weather liars get to report about 90+ even though in all the years past it was 80. We all know that the humidity makes it feel worse, but the actual temp is pretty standard when compared to previous years.
