"An oversimplified picture
of the climate behavior
based on a single process
can lead to distorted
conclusions."

The paper is a summary
of the climate system
and history of climatology.
Atmospheric physicist
Dr. Richard Lindzen
summarizes the
“implausible”
claims made
about dangerous
anthropogenic
(man made)
global warming.
Dr. Richard Lindzen
is now retired
but his research
is still cited about
600 times per year.
Lindzen recently
published another
scientific paper
(Lindzen, 2020)
in The European
Physical Journal
criticizing the
current alarmism
in climate science.

"Highlights:
1. Doubling the atmospheric CO2 concentration from 280 ppm to 560 ppm results in just a 1-2% perturbation to the Earth’s 240 W/m² energy budget. This doubled-CO2 effect has less than 1/5th of the impact that the net cloud effect has. And yet we are asked to accept the “implausible” claim that change in one variable, CO2, is predominatly responsible for altering global temperatures.
2. A causal role for CO2 “cannot be claimed” for the glacial-to-interglacial warming events because CO2 variations follow rather than lead the temperature changes in paleoclimate records and the 100 ppm total increase over thousands of years produce “about 1 W/m²” of total radiative impact.
3. Climate science didn’t used to be alarmist prior to the late 1980s. Scientists were instead sufficiently skeptical about claims of climatically-induced planetary doom. That changed during the years 1988-1994, when climate research centered on CO2 and global warming received a 15-fold increase in funding in the US alone. Suddenly there was a great financial incentive to propel alarming global warming scenarios.
4. Concepts like
“polar amplification”
are “imaginary”.
“The change in equator-to-pole temperature difference was attributed to some imaginary ‘polar amplification,’ whereby the equator-pole temperature automatically followed the mean temperature. Although the analogy is hardly exact, this is not so different from assuming that flow in a pipe depends on the mean pressure rather than the pressure gradient.”
From Lindzen, 2020:
“The two most important greenhouse substances by far are water vapor and clouds. Clouds are also important reflectors of sunlight. These matters are discussed in detail in the IPCC WG1 reports, each of which openly acknowledge clouds as major sources of uncertainty in climate modeling. vi. The energy budget of this system involves the absorption and reemission of about 240 W/m2. Doubling CO2 involves a perturbation a bit less than 2% to this budget (4 W/m2) [33]. So do changes in clouds and other features, and such changes are common.”
