Study: 25-45 Percent Of Warming Since 1950s Down To Urbanization, Not CO2
Why have sea surface temperatures and proxy temperature reconstructions so strongly diverged from the instrumental land record in recent decades?
Because “0.36 ± 0.04 °C” of non-climatic warming is from roofs, asphalt, machines, vehicles…artificially enhance the post-1950’s global temperature trend.
A new analysis (Scafetta, 2021) suggests:
• Urban Heat Island (UHI) effects can raise city temperatures 6-9°C above the temperatures in surrounding rural areas. These significant biases are not sufficiently removed from instrumental records.
• Sea surface temperatures and land temperatures showed matching variations and amplitudes from 1900 to 1980. After 1980, land surface temperatures rose substantially more, suggesting nearly half of the land temperature increase is non-climatic.
• Tree-ring temperature reconstructions showed a strikingly similar pattern of amplitude and oscillation prior to the 1980s. After the 1980s, the instrumental record claims more than twice as much warming as the proxy records.
• Between 25-45% of the warming from 1940-1960 to 2000-2020 appears to be artificial, or non-climatic.
• Climate models overestimate the 1940-1960 to 2000-2020 climatic warming by about 40% in hindcasts.

The title of this article is terrible. It completely defeats the purpose of the article itself. Be aware that most people don’t read/understand the body of the article. But they form firm conclusions based on their impression of what the article says about the the broader discipline. This title will leave the average person with the impression that science has a precise measurement of temperature and/or that tempeature calculation in general are highly deterministic. Both of which are absurd to anybody who actually understand and/or studies this subject.
