A sad day for science, a good day for left wing eco terrorists!

“Science coverage does not simply lie in reflecting a wide range of views but depends on the varying degree of prominence such views should
be given.”
The Trust said that man-made climate change was one area where too much weight had been given to unqualified critics.
In April the BBC was accused of misleading viewers about climate change and creating ‘false balance’ by allowing unqualified sceptics to have
too much air-time.”

Through the late 1990′s and early 2000′s the conclusion that global warming is real was scientifically acceptable.
The next stage is usually peer review and scrutiny and this is where the theory runs into problems.
The standard scientific method goes:
Observations->Hypothesis->Experiment->Analysis
Observations: A warming/CO2 concentration correlation and CO2 absorbs IR spectra
Hypothesis: Emissions cause global warming
Experiment: Climate Model
Analysis: Model simulations comparison to observations

Global mean surface temperature over the past 20 years (1993–2012) rose at a rate of 0.14 ± 0.06 °C per decade (95% confidence interval).
This rate of warming is significantly slower than that simulated by the climate models participating in Phase 5 of the Coupled Model
Intercomparison Project (CMIP5). To illustrate this, we considered trends in global mean surface temperature computed from 117 simulations
of the climate by 37 CMIP5 models.
We find an average model simulated rise in global mean surface temperature of 0.30 ± 0.02 °C per decade (using 95% confidence intervals on
the model average).
The observed rate of warming is less than half of this simulated rate, and only a few simulations provide warming trends within the range of
observational uncertainty.
=======================================
seems the difference is prominent & “deserves plenty of air time”
anyhow, I’m glad the alarmists will have their air time reduced so the viewers aren’t misled.
