Record Heat In California Claims Not Supported By Data

By Paul Homewood



I suspect we’re going to hear this lie a lot in the next few weeks.

The only problem is that it is not true:




In the midst of the state’s most destructive wildfire season, California shattered temperature records in August, September and October.

All three months were the state’s warmest on record, according to a new report by UCLA climate scientist Daniel Swain.

“The long-term warming trend during the peak of fire season in California has been especially pronounced,” Swain said on Twitter, “and 2020 really puts an exclamation point on that.”


The report linked gives this map showing that the £record heat” was principally along the coast in October:




However, when we check out monthly temperatures in Los Angeles and San Francisco, we find that none of the three months were anywhere near being a record:










There will of course have been several degrees of warming due to urbanisation since the 1930s, making current temperatures even less remarkable.

When we look at long term trends, it is often claimed that the time of observation has changed, which can affect monthly average trends very slightly. However, station metadata shows that the time of observation has remained the same throughout at both sites, which have measured at midnight every day.

I have little doubt that the official NOAA version will support Daniel Swain’s claims. If it does, it will simply reduce their credibility even further.

This is little better than fraud.
