The BBC have been putting out a programme on Sundays at 9pm on BBC2 for the last two weeks on global warming. The final part is next Sunday. The programmes can be viewed online HERE. It seems clear to me that the series is propaganda in favour of the theory of man-made global warming. Three hour long programmes is rather tedious and the presenter, Dr. Ian Stewart, tries hard to give the impression that he is a neutral observer, while clearly steering us to one conclusion. Unfortunately for the BBC their programme clashes with a popular drama and viewing figures have been low (only 1.6 million).
In the first programme he reviews the history of the subject and in the second he seeks to demonstrate that the evidence clearly shows that man-made CO2 is the cause of the recent warming. His main "evidence" was the notorious hockey-stick graph of temperature over the past thousand years which has been discredited by many reviewers, see HERE and HERE.
In the programme he even concedes that there is strong evidence that Greenland was warmer during the medieval warm period than it is today, but then goes on to state that the Hockey Stick graph says it didn't happen. In other words he believes that a reconstruction using tree-rings is more reliable than actual written evidence.
The BBC would like us to believe that the "climate wars" are over and that the alarmists have won, but in fact they are just entering a new phase when the computer model prediction meet with the reality of climate, and this is a battle even the BBC may have trouble with.
Hi,
ReplyDeleteTree rings are certainly not the only proxies used in past climate reconstruction and I would be genuinely interested to know what the 'actual written evidence' of past Greenland temperature is please?
Yes' the BBC's 'Climate Wars' is predictably biased towards the Gore camp; Stewart simply dismissed the counter-evidence of Channel 4's 'The Great Global Warming Swindle' in 30 seconds flat!
ReplyDeleteAnd in the final programme we will get the full 'green' lobbyist propaganda about the economically masochist future they intend to impose on us.
To my first comment - For more on the evidence for Greenlands climate I will refer you to the website of John Daly.
ReplyDeleteTo the second comment - I fear you are right. I predict a tour of the Arctic and assorted glaciers in retreat and he will try to scare us into believing in apocalypse.
RE Greenland,
ReplyDeleteThanks for the reply but isn't the The whole point of using multi-proxy reconstructions (not just tree ring data) to find a hemispheric or global signal. I liked John Daly's research style but cannot conclude from the evidence in that link that global temperatures (and we're talking a global phenomena) were as elavated as Greenland's?
The John Daly site discusses many other examples around the world where there is good evidence of temperatures in the past thousand years being warmer than today. Use the link (above) and scroll down to find them. Today's temperatures are not exceptional.
ReplyDeleteThe Vostok Ice Core Data demonstrate that temperatures there were warmer than the current mean temperature as recently as 190 years ago.
ReplyDeleteAs I noted in this post, the propagandists (KNOWING that the science is NOT on their side) have skipped the scientific debate altogether. They have already moved on. Their current agenda is propagandizing on behalf of the utterly disastrous policy response.
Fortunately, cooler heads are beginning to prevail.

ReplyDeleteYour tactic of admitting Greenland was warmer thousands of years ago, but questioning the rest of the global data is a familiar one. The IPCC used it in their latest propaganda (er, sorry, “report”).
This tactic is a great way to keep the gravy train of easy research money flowing.
Tax payers have already been bilked for an estimated $50,000,000,000in researching this nonsense. I say the debate IS over, CO2 is NOT a problem and world monetary resources can be FAR better spent on FAR more pressing concerns!
