Climate science should be less political, while climate policies should be more
scientific. Scientists should openly address uncertainties and exaggerations in
their predictions of global warming, while politicians should dispassionately
count the real costs as well as the imagined benefits of their policy measures
Natural as well as anthropogenic factors cause warming
The geological archive reveals that Earth’s climate has varied as long as the
planet has existed, with natural cold and warm phases. The Little Ice Age
ended as recently as 1850. Therefore, it is no surprise that we now are expe
riencing a period of warming.
Warming is far slower than predicted
The world has warmed significantly less than predicted by IPCC on the basis
of modeled anthropogenic forcing. The gap between the real world and the
modeled world tells us that we are far from understanding climate change.
Climate policy relies on inadequate models
Climate models have many shortcomings and are not remotely plausible as
policy tools. They do not only exaggerate the effect of greenhouse gases, they
also ignore the fact that enriching the atmosphere with CO2 is beneficial.
CO2 is plant food, the basis of all life on Earth
CO2 is not a pollutant. It is essential to all life on Earth. More CO2 is favorable
for nature, greening our planet. Additional CO2 in the air has promoted growth
in global plant biomass. It is also profitable for agriculture, increasing the
yields of crops worldwide.
Global warming has not increased natural disasters
There is no statistical evidence that global warming is intensifying hurricanes,
floods, droughts and suchlike natural disasters, or making them more frequent.
However, there is ample evidence that CO2-mitigatiion measures are as damag-
-ing as they are costly.
Climate policy must respect scientific and economic realities
There is no climate emergency. Therefore, there is no cause for panic and
alarm. We strongly oppose the harmful and unrealistic net-zero CO2 policy
proposed for 2050. Go for adaptation instead of mitigation; adaptation works
whatever the causes are.
OUR ADVICE TO THE EUROPEAN LEADERS IS THAT SCIENCE SHOULD
STRIVE FOR A SIGNIFICANTLY BETTER UNDERSTANDING OF THE CLIMATE
SYSTEM, WHILE POLITICS SHOULD FOCUS ON MINIMIZING POTENTIAL
CLIMATE DAMAGE BY PRIORITIZING ADAPTATION STRATEGIES BASED OR
PROVEN AND AFFORDABLE TECHNOLOGIES
To believe the outcome of a climate model is
to believe what the model makers have put
in. This is precisely the problem of today’s
climate discussion to which climate models
are central. Climate science has degenerated
into a discussion based on beliefs, not
on sound self-critical science. Should not
we free ourselves from the naive belief in
immature climate models?
