founders Dr. Patrick Moore and covers a large

The Problem with Climate Change Politics

of hyping up climate change into a full-blown crisis
has become the consequence of a crowd psychology

The oceans absorb much more CO2 than assumed!

MWe. The reactor will be built in Wyoming, probably
on the site of a former coal power station.

report by Prof. Ole Humlum; this is a
report based on observations, not models! Just
one sentence of this outstanding report:
"Since 1979, lower troposphere
temperatures have increased over both land and
oceans, but most clearly over land areas. The most
straightforward explanation for this phenomenon is
that much of the warming is caused by solar
insolation, but there may well be several
supplementary reasons, such as changes in cloud
cover and land use."

Prof. Judith Curry:
"This redefinition of ‘climate change’ to refer only
to manmade climate change has effectively eliminated
natural climate change from the public discussion on

has become a dominant cause of societal
problems...This grand narrative misleads us to think
that if we solve the problem of manmade climate
