That would be true if we had only two measurements. But it can't explain the trend over the last 40 years (neither can the introduction of digital thermometers in the 60s).
- lettergram 3y agoThere are a multitude of things simultaneously that need to be considered: 1. The sun naturally has cycles where it increases and decreases in temp 2. The measurement devices we use have changed over time 3. The location of our measurements have changed over time 4. We only have 120-160 datapoints total for yearly averages.. with the above issues associated. Because of those points it’s hard to make any absolute claims, besides the argument since 1960s the trend is slightly upwards in terms of temperatures , maybe.
