Based on 39 years working in the same remote environment, yeah we’re warming up. Why? Take a look at that big yellow marble in the sky. It breathes, we breathe. We’re not going to stop that.
For a little fun, take a look here.

NOAA data is NOT to be trusted. Too many of the weather stations are sited wrong or not maintained or both.
About 35-40 years ago I worked for a company that manufactured and installed electronic signs in airports. Those signs primarily provided flight arrival and departure information for passengers. Some were large TV monitors.
Although software engineers, the guys in my group made many trips to airports all over the world during installation or debugging those systems. We all noticed that airports all over the planet were moving those little white weather sensor housings from their original positions to places that were just plain lousy for those devices. The NOAA rules for those housings are very explicit. The sensors were moved from compliant positions to strongly non-compliant positions. Conspiracy indeed. We watched them do it.
