John Cook loves to quote the statistic that “there are more record highs than record lows” in recent years.
Well surprise, surprise surprise. Study after study has shown that urbanization keeps nighttime temperatures up. This has been understood for hundreds of years. Even in the tiny town of Barrow, Alaska – UHI keeps winter temperatures 2.2C above the surrounding regions.
During winter (December 2001–March 2002), the urban area averaged 2.2 °C warmer than the hinterland. The strength of the UHI increased as the wind velocity decreased, reaching an average value of 3.2 °C under calm (<2 m s?1) conditions and maximum single-day magnitude of6 °C

Phoenix has 4-7C nighttime warming
The average minimum May temperature at the urban locations displayed an apparent upward increase through the time series (1910 through 2000), which was attributed to the urban growth of the region. By the end of the series, there was a +4 to 7 ºC (7 to 13 ºF) difference between the urban minimum temperatures and the rural minimum temperatures
Of course there are fewer record lows, and the reasons are well understood. No need for alarmists to lie about it.
“no need for alarmists to lie about it” Umm, alarmist claims are based on lies. Lying is their default position.
“I could not help myself. It is my nature”, said the scorpion to the frog.
I have been preaching the UHI gospel for over twenty years, and those who heard me understood, it makes perfect sense. Only through massive global collaboration, deep deceit, and funding that Midas would envy, has this simple truth been buried.
Can’t stand the heat? Get out of the city. 😉
Only a climate scientist could miss the obvious fact that manmade structures help keep people warmer than sleeping in the open.
Even snakes can appreciate this obvious fact – I had a friend that used to collect snakes for venom extraction from some hilly bushland near Brisbane. Winter was the easiest time to do this – they were all on the asphalt road after sunset trying to keep warm so easy pickings.
We were stopped by police one night who thought we looked like typical young cannabis users. They searched the car and found a sack in the trunk. Despite a warning not to they opened it to find 3 death adders and a couple of brown snakes.
They were lucky as brown snake venom is one of the most toxic in the world with a LD50 figure placing it about number 3 in the world. Brown snakes can be aggressive and grow to five metres.
Death adders are usually placid but still make the top ten in LD50.
Lucky it was winter.
