March 30, 2020 was
30th anniversary
of the publication
by Roy Spencer
and John Christy
in Science Magazine.
From the abstract:
“Passive microwave
radiometry from
satellites provides
more precise atmospheric
temperature information
than that obtained from
the relatively sparse
distribution of thermometers
over the earth's surface.
Accurate global atmospheric
temperature estimates
are needed for detection
of possible greenhouse warming,
evaluation of computer models
of climate change, and for
understanding important
factors in the climate system."
Monthly data go back
to December 1978.
Data are independently
verified by temperature
trends measured by
different instruments
on weather balloons.
These are the only
global temperature
trends existing.
A goal in measurement
is to measure as directly
as possible.
Surface air
temperature
measurements
are non-global,
and affected
by changes
in land use,
particularly
urbanization.
“As the years went by, we would learn that the lack of substantial warming in the satellite data was probably hurting NASA’s selling of ‘Mission to Planet Earth’ to Congress."
The bigger the perceived problem, the more money a government agency can extract from Congress to research the problem.
At one point a NASA HQ manager would end up yelling at us in frustration for hurting the effort.”
“In 2001, after tiring of being told by NASA management what I could and could not say in congressional testimony, I resigned NASA and continued my NASA projects as a UAH employee in the Earth System Science Center, for which John Christy serves as director (as well as the Alabama State Climatologist).”
NASA management
filters information
to promote a climate crisis,
for which they need money
to understand and fix.
The top “climate crisis”
promoter is the UN
Intergovernmental Panel
on Climate Change IPCC).
