All of this must come as surprise to anybody old enough to remember the killer heatwaves of the 1930s and 50s in the State.

From NOT A LOT OF PEOPLE KNOW THAT

According to NOAA, Texas has just had its second warmest summer; only 2011 was hotter. And it’s a similar story in Dallas, which uses data from the Dallas Love Field FAA Airport:

All of this must come as surprise to anybody old enough to remember the killer heatwaves of the 1930s and 50s in the State.

So step forward the small city of Corsicana, which has a population of 25000 and is located 50 miles from Dallas:

The weather station at Corsicana has been part of the high quality U.S. Historical Climatology Network (USHCN) since 1880, which for years was used to quantify national and state temperature trends. By and large, USHCN sites were in small towns and rural areas, for obvious reasons. All USHCN stations had to meet high standards of equipment, siting and recording practices, to ensure the data was reliable.

Lo and behold, when we check the data there, we find that this summer was a long way from being the second warmest. Not only was it hotter in 2011, it was also in 1925, 1934, 1954 and 1998:

For instance, the summer of 1954 averaged 87.3F, compared to 86.7F this year, a difference of 0.6F. But in Dallas the comparative figures were 88.9F and 89.6F, a difference of 0.7F.

Overall since 1954 therefore, temperatures in Dallas have increased by 1.3F in comparison to Corsicana, (0.6 + 0.7F).

Obviously there can be no climatological reason for this, as the two locations are so close. And metadata confirms that there have been no significant location changes at Corsicana, or any changes in time of observation.

The only possible cause of the discrepancy is, of course, UHI.

Further evidence that the Corsicana data is telling the real story lies in the number of days over 100F. Clearly the 1930s and 50s stand out for their heat:

Meanwhile, the correct climate trends have been adjusted away by GISS, homogenised to agree with all of the big city and airport temperature data:

According to NOAA, Texas has warmed by 1.5F since the start of the 20thC, but their own data indicated that nearly all of this “warming” has been due to UHI:

Some people would call this outright fraud!
