Because almost everyone who remembers a global record cold month is dead. Compare to record global hot months where the only living people who don't remember several are young children.
Take a look at this NOAA report for August 2023 [1], and scroll down to the chart showing August temperature anomalies going back to 1850.
The last record low August was in 1911. We've had 45 consecutive Augusts that were above the 20th century average.
That's how it is for all months. E.g. for January the last record low was around 1895, and we've had 47 consecutive Januaries above the 20th century average.
We are currently up to 534 consecutive months above 20th century average.
The pattern is similar for years. The last global record cold year was 1904.
