The Scientific Debate on Climate Change: Part 7, 8, 8a

7. Climate Change – “Those” e-mails and science censorship

Are climatologists censoring scientific journals and silencing alternative hypotheses on climate change? This is the second part of my look at the hacked/stolen e-mails from the Climatic Research Unit in the UK. I welcome intelligent opinions in the forum, but please refrain from posting the same inane comment a dozen times. Debates in science aren’t settled by those who argue the longest or the loudest, but by the accuracy of facts and the consistency of hypotheses with the facts.


8. Climate Change — Has the Earth been cooling?

This video also looks at whether other planets are also warming, and an Internet myth that NASA is now attributing warming to the sun. In this video I examine the importance of sources — tracking information back to a source and making sure the source is credible. My sources are cited in the video, but I’ll also post them here. Sources are also cited throughout my climate change series. These videos are not a personal opinion or a theory of my own; I’m not a climate scientist or a researcher and I have no qualifications to do anything other than report on what real climate scientists have discovered through their research. So there’s no point in disagreeing with me. If you dislike their conclusions, take it up with the researchers I cite. If I’ve made a mistake in reporting their conclusions, please point out the mistake and I will happily correct it. If you think you know better than the experts, write a paper and have it published in a respected, peer-reviewed scientific journal.


8a. Climate Change – supplement

The perfect example of what I was saying in my last video appeared soon after it was uploaded. The Internet was abuzz with a quote from Professor Phil Jones that there has been no global warming since 1995.
But is that what he actually said? Once again, we need to go to the source — Jones’s own words — rather than Internet gossip based on an interpretation of what he said. If we check the primary source, it’s a very different story. In fact, Jones and his team did detect warming since 1995. In this video I go to the source, and find out why the tabloid press got things so wrong. I have to correct part of the video where I gave an example of what an 80% statistical significance would mean (for the statisticians out there, this is a p-value of 20%). I said this would mean 80% confidence that global warming was a real, underlying trend, and not the result of background fluctuations.
While some statisticians accepted this as a broad explanation for the layperson, others felt it deviated too far from the precise meaning, which is this: =If global warming was not happening, there is only a 20% chance we would see this result.= A 90% statistical significance (if that’s what Jones achieved) of the 1995-2009 temperature data would mean If global warming was not happening, there is only a 10% chance we would see this result.

Greenland Glacier 4X Size of Manhattan Breaks Loose

This really struck me as a fascinating piece of science news: A University of Delaware researcher reports that an “ice island” four times the size of Manhattan has calved from Greenland’s Petermann Glacier. The last time the Arctic lost such a large chunk of ice was in 1962. “In the early morning hours of August…Read More

Climate Change: The Scientific Debate

Quite interesting, even handed, and intelligent:

Part 1 Climate Change — the scientific debate

A basic look at how climate scientists infer that man-made carbon gases are changing the climate, and how this view is contradicted by other climate scientists who are skeptics.
I am a former science correspondent with an interest in reporting the facts, not the media hype. My thanks to 9thgate for checking my script for errors.


Part 2: Climate Change — the objections

This video, the second in the series, looks at alternative hypotheses explaining global warming. I am only looking at alternative hypotheses put forward by real, professional climate researchers, and the findings of real, professional climate researchers who disagree with them. Yes, I’ve left a lot of the detail out. This is a 10-minute video summarizing the arguments and counter-arguments, not a PhD thesis. The comments forum will be free and open, as always, but if you disagree with what real, professional climate scientists say, please take it up with them and dont expect me to defend their point of view. If you have a stunning piece of scientific evidence that disproves one side or the other, dont waste time on my channel, write a paper, and get it peer-reviewed and published in a reputable journal.


Part 3 – Climate Change — Anatomy of a myth

I had planned to put several myths in this video, but discovered such an appalling web of deceit and fabrication in this first one that I felt I had no choice but to thoroughly debunk it. Like many ingrained myths, this one is so ubiquitous that it takes an awful lot of hard evidence to convince true believers that it’s been fabricated.

How Bad is BP Deepwater Horizon?

Here is a decidedly contrarian viewpoint, from University of Alabama Professor Dr. Roy Spencer. Prof Spencer notes that the general commentary regarding the BP spill as “the worst environmental disaster in history” is wildly overblown. His graph below is designed to put this spill into perspective. Now, before you wail that he is a global…Read More
