New Study Finds 25-45% Of The Instrumental Warming Since The 1950s Is Due 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 from roofs, asphalt, machines, vehicles…artificially enhances the post-1950s 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, the land surface temperatures rose substantially more, suggesting nearly half of the land temperature increase is non-climatic.
