> What if our interments for measuring temperature were improving over the last century? Thermometers have been around pretty much unchanged for a long time. We don't need particularly high precision measurement for an overall trend on the measurement scale of tenths of degrees Celsius. > What if the locations of the measurements changed slightly? Then we'd expect momentary level and trend shifts whenever the location changes. > And finally, what if we’re exiting an ice age (we are still technically in one)? We are, but much much faster than would occur without human activity.
