I thought warmer nights were a fingerprint of CO2 induced warming? John Cook has claimed that at least five times on his blog: The human fingerprint in the daily cycle. It’s also known as Diurnal Temperature Range, and the theory is that extra CO2 keeps us warm all night.
Now Excellent* (Alarmed) Climate System Experts are saying that UHI (Urban Heat Island) effects can cause warmer nights too, at least in the future. (Perhaps this only applies to future-bricks, not past ones — you think?)
City expected to feel heat as it expands
Parts of Sydney will be up to 3.7 degrees hotter by the year 2050, as urban expansion spawns ever more asphalt and concrete, new research suggests.
The ”urban heat island effect” – the build-up of heat in built-up areas – will amplify climate change, particularly in the outer fringes of Australian cities, according to University of NSW researchers.
”If you are living near the edge of a city today, you will notice the temperature change, mainly through the minimum temperature change at night,” said Daniel Argueso, the lead author of the study that was prepared at the Centre of Excellence for Climate System Science.
Just when you thought it couldn’t get worse for the cult of the carbon scare.
Now we need to ask if the world has even warmed? I’ve always said, “global warming is real”, but the recent exposés of shocking corruption in science have made me start to wonder whether even that is true.
Today a study by Joe D’Aleo and Anthony Watts, was announced by the Science and Public Policy Institute (SPPI).
From their media release:
An extensive survey of the literature and data regarding ground and sea surface temperature records uncovers deception through data manipulation, reports the Science and Public Policy Institute (SPPI).
Authors veteran meteorologists Joe d’Aleo and Anthony Watts analyzed temperature records from all around the world for a major SPPI paper, Surface Temperature Records – Policy-driven Deception? The startling conclusion that we cannot tell whether there was any significant “global warming” at all in the 20th century is based on numerous astonishing examples of manipulation and exaggeration of the true level and rate of “global warming”.
That is to say, leading meteorological institutions in the USA and around the world have so systematically tampered with instrumental temperature data that it [...]
The headline is tongue in cheek, but the message is serious.
Look at these pictures of NOAA’s U.S. temperature stations. These thermometers on the ground have recorded faster temperature rises than sensors on satellites and weather balloons.
Lucky heat doesn’t rise off asphalt…
