    The EPA page on the Heat Island Effect…

    The term “heat island” describes built up areas that are hotter than nearby rural areas. The annual mean air temperature of a city with 1 million people or more can be 1.8–5.4°F (1–3°C) warmer than its surroundings. In the evening, the difference can be as high as 22°F (12°C). Heat islands can affect communities by increasing summertime peak energy demand, air conditioning costs, air pollution and greenhouse gas emissions, heat-related illness and mortality, and water pollution.

    Alarmists are always yapping about higher night time lows, as if it were a CO2 driven thing. And exactly what is the UHI adjustment from the team?

    Just an average summer day here in North Texas. The average high temp on this day is 97 degrees F. The low is usually in the high 70s to low 80s depending on whether a high pressure system is in place. Suck it up weenies from the Northeast.

    Most summers on the East coast of Australia have 40 to 42 degree days, often with night time temperatures in the high thirties. People don’t suddenly start dying every summer. There’s the occasional day when it’s around 45 degrees when people are either at work, or shut themselves inside with the house closed up and air-conditioning on. That’s why us humans developed all of this technology, so we can adapt.
