Dr. Roy Spencer does outstanding work. His team is responsible for official satellite temperature recording in the US. He has a blog here that you should read if you are at all interested in climate science. (RS Blog)
Among Dr. Spencer’s interests has been the extent to which the US temperature record, and indeed that around the world, has been influenced by increased urbanization. Cities are hot, much hotter than the countryside. After a long struggle his team has finally gotten their work published in a peer-reviewed journal. The struggle tells you as much as the paper. Read his post on the paper to see how hard people fought to keep his research from being published or to force modifications. The reviewers mention the homogenization issue. You need to understand that the raw data on temperatures is typically put through a series of bullshit algorithms designed to support the climate hysteria narrative. They are called things like homogenization and time of observation adjustments but they are algorithms written by climate hysterics.
And when you read the paper itself, you see why the alarmists wanted to stop it. It finds that at least 65% of alleged warming is due to urban heat island effects. As noted above, there is other data and analytic mischief that the hysterics use to further corrupt the real data. At some point in the future, when and if the world becomes rational again, scientists will use the climate hysteria as the primary example of science being perverted for ideological and political reasons, supported by billionaires who just wanted to get even richer from the associated renewable energy scam.

The big city heat island effects are not rocket science. We all experience it.
Take driving for example, around the beltway, I-494/I-694.
Go south (or north) on Hwy 100 (or 169 or I-494) from I-694 to south of I-494 and you will see the 2, 3, 4F higher heat affects on your car’s outside temperature reporting.
If you live just north of Minneapolis, you’ll need to see the temperature in St. Cloud or Rochester to more closely match the temperature outside your house windows.
Have you noticed watching local TV weather reporters, Paul Douglas on radio and newspaper is a good example, act a bit sheepishly when they show the local temps on the TV?
Temperature reporting is an embarrassment; it’s obvious that Minneapolis is warmer than every surrounding city. Yet that is the temperature reference.
Yep, there they are screaming global warming!
This study reminds me of another study from 1, 2, 3 or so years ago.
Around the U.S. ( and Minnesota) there is a second set of temperature gauges set away from heat islands.
If I remember correctly, the study concluded there was no warming, indeed it appeared to have some overall cooling.
BTW, if what I see about cycles, sun especially, this year should experience a the final warming year before another cooling cycle begins.
Hot and dry. Then, ouch, grain crop production goes into reverse. 🙁

The historical australian temp records have similar issues with the adjustments. A regular commentator at climate etc dot com named Geoff Sherr—has commented on how the reported historical australian temps dont match up well with the raw temps.
