Prof. Linzen listed the following topics which are often exploited by the panic brigade to win our attention:-

• ·         ‘the  97%’,
• ·         ‘warmest years on record’,
• ·         extreme weather ,
• ·         sea level rise,
• ·         Arctic sea ice,
• ·         polar bears,
• ·         ocean acidification,
• ·         coral reefs,
• ·         ‘global warming as the cause of everything’.

& says:-

‘The accumulation of false and/or misleading claims is often referred to as the ‘overwhelming evidence’ for forthcoming catastrophe. Without these claims, one might legitimately ask whether there is any evidence at all.'

He ends:-

I haven’t spent much time on the details of the science, but there is one thing that should spark skepticism in any intelligent reader. The system we are looking at consists in two turbulent fluids interacting with each other. They are on a rotating planet that is differentially heated by the sun. A vital constituent of the atmospheric component is water in the liquid, solid and vapor phases, and the changes in phase have vast energetic ramifications. The energy budget of this system involves the absorption and reemission of about 200 watts per square meter. Doubling CO2 involves a 2% perturbation to this budget. So do minor changes in clouds and other features, and such changes are common. In this complex multifactor system, what is the likelihood of the climate (which, itself, consists in many variables and not just globally averaged temperature anomaly) is controlled by this 2% perturbation in a single variable? Believing this is pretty close to believing in magic. Instead, you are told that it is believing in ‘science.’ Such a claim should be a tip-off that something is amiss. After all, science is a mode of inquiry rather than a belief structure.’
