IPCC 'science' is based on 7 mistakes, as any competent physicist can work out..
1. Pyrgeometers measure a temperature signal: 'back radiation' does not exist.
2. There is next to zero GHG emission IR from the earth's surface – standard physics.
3. There can be no direct thermalisation of residual IR in the atmosphere.
4. There can be no cooling by polluted clouds because Sagan got the physics wrong.
5. Houghton wrongly claimed lapse rate warming is the GHE so Hansen wrongly claimed 33 K.
6. The models are a perpetual motion machine: there is no CO2-AGW or positive feedback.
7. Subtle physics means terrestrial instruments measure a much higher IR signal than reality.
To summarise; no independent, competent professional accepts the 'consensus'. They are drifting away, sick and tired of fake science being used to enrich carbon traders.
