If they were talking about maximum recorded temperatures, your argument would've made sense.
However, they're talking about average temperatures, for which a 30 year range is certainly not meaningless.
- busymom0 7y agoHere’s the same data for the minimum temperature records broken: https://www.ncdc.noaa.gov/extremes/scec/records/all/tmin https://www.ncdc.noaa.gov/extremes/scec/records/all/tmin Around 10 were broken in the last 3 decades which is more than the around 7 broken for the max temperatures. If more min records are broken, then I would expect the average to be going down not up.

You would expect so but the data about temperature anomalies suggests the opposite: Annual 2019 Average Temperature Anomalies in USA: https://www.ncdc.noaa.gov/sotc/national/201913/supplemental/page-2 https://www.ncdc.noaa.gov/sotc/national/201913/supplemental/...

- piva00 7y agoMinimum records being broken can mean more variance causing outliers more frequently, wouldn't necessarily mean that they push the average down as they might be short events followed by a different weather pattern. The disruption of the polar vortex drops temperature significantly across Northern Europe but it can be caused by the warming of the atmosphere so even though it can cause record lows it is a short lasted event and on average the temperature is still going up. That is also a side-effect of climate change, more powerful bursts of extreme weather.
