If you did that using the data collected by the various global warming of the largely disappears which is not what the catastrophists in the climate debate want. Their false warming is mostly caused by the Urban Heat Islanding effect which we are told by experts does not affect the global temperature readings and is fixed by small adjustments. Other experts peddling deaths by catastrophic city heating tell us UHI is a huge problem.
