I'm watching this at the moment.
I've never seen such a poor science program and such a blatant piece of propaganda.
For instance showing two screens showing actual weather data and modelled weather data. On its own very compelling: the real and modelled weather tracked almost exactly.
But:
(Lets ignore the warmist's argument that weather isn't climate and look at what we're being shown). Okay, the screen at the top is showing historical data. The lower screen is showing modelled data (also it can be assumed, historical as it runs at the same time as the top screen). Whats not clarified (as its key to the AGW argument) is how well the modelled data showed
future weather patterns. It only shows the correctly modelled historical data, without any mention of the number of data runs, tweaks to data or how far ahead of what really happened the data was modelled. Anyone can get it right with hindsight; the clever thing is to get it right and model weather several hours, days and months ahead of the fact.
Without the information behind the computer model, we can't make an objective decision. Instead we are asked blindly to accept the program's supposition that the weather model accurately predicts weather in real-time hours, days and even years into the future. Because that's what warmists want you to believe: that they can accurately predict the climate many years into the future.
Lets get down to the facts about global warming: yes, climate is changing BUT it has changed in the past and will continue to change in the future. It has been far cooler in the past, which we call Ice Ages. It has also been warmer in the past. Its been significantly warmer before the industrial revolution. So if the huge amounts of CO2 humans are producing is to blame, then how is warming without CO2 explained?
The science of man made global warming is one of observation: climate has been observed to warm up and CO2 levels are rising. But there is no link between the two: only because the two happen at the same time are we asked to believe there is a link. And you'd believe it, if you weren't in possession of the facts that climate has warmed without CO2 in the past.
The tone of the program is pure propaganda. When covering climategate, we're told Freedom of Information requests are "harrassment", when all thats being asked for is the raw data the scientists used to come to their conclusions. FOI requests aren't harrassment, they're perfectly legal and just means of requesting scientific data in order to corroborate findings. There is no scientific reason why the data wasn't released: in fact the only reason appears to be that the scientist in charge has a huge ego and didn't like oiks asking for his precious data.
There are so many apparent flaws in the program it can only be classed as propaganda. There was no debate, no balanced views from either side, instead all that was proffered is the usual warmist line that the science is settled, there is no dissent, man made global warming is real, we can predict future weather and climate accurately because our computer models are so good, despite failing to predict successive cold winters, we understand fully what is happening, the mechanism causing global warming is identified, man made CO2 is causing global warming, despite it having been far warmer before the industrial revolution..
I used to enjoy BBC scientific documentaries when I was a kid. Sadly tonight I was reminded why I don't watch them any more.
