"There is a lot of inaccurate nonsense about climate science written in blogs and the media, whether exaggerating the effects of climate change or seeking to undermine the science behind it. This series checks the sources of these claims and shows how they have been misinterpreted or deliberately altered. I have no expertise in climatology, I am a former science journalist, so checking facts is what I do. And I always cite these sources so you can check them for yourselves. Along the way, I explain the real science as relayed by researchers in published papers, in a way that makes it easy to understand." - Potholer54

     Thumbnail         1. Climate Change -- the scientific debateby potholer54 279,128 views

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.…

    2. Climate Change -- the objections

    by potholer54 126,284 views

    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 i…

    3 - Climate Change -- Anatomy of a myth

    by potholer54 120,963 views

    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 …

    4 - Climate Change -- Gore vs. Durkin

    by potholer54 83,749 views

    This video, the fourth in my Climate Change series, looks at urban myths spawned by two iconic films -- An Inconvenient Truth and The Great Global Warming Swindle. Whatever you "believe" about climate change, there is no excuse for the kind of exaggerations, fallacies and fabrications we see in films like these…

    5. Climate Change -- isn't it natural?

    by potholer54 85,295 views

    More urban myths about climate change are busted as I look at the Earth's climate over the last 500 million years. What causes it to change? Since carbon dioxide was much higher in the past, why do climatologists say higher CO2 now poses a problem? And of course there's the familiar myth that CO2 can't inf…

    6. Climate Change -- Those hacked e-mails

    by potholer54 280,037 views

    Now that the conspiracy theorists have blown off steam, it's time for a more sober analysis of those e-mails and what they mean. I can't go through all of them, there are far too many, and . So I've taken the two that seem to be getting conspiracy theorists most worked up -- Phil Jones's e-mail about "Mike's Nature t…

    7. Climate Change - "Those" e-mails and science censorship

    by potholer54 60,000 views

    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 inan…

    8. Climate Change -- Has the Earth been cooling?

    by potholer54 76,788 views

    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 po…

    by potholer54 54,263 views

    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…

    12 - 'Doubled CO2 means just 1.64 degrees of warming...' or maybe not.

    by potholer54 33,419 views

    Last week a paper by researchers at NASA's Goddard Institute for Space Studies led to sensational headlines that the Earth will only warm by as much as 1.64 degrees centigrade -- in a couple of centuries. Sound too good to be true? Of course it does. …

    Monckton bunkum Part 5 -- What, MORE errors, my lord?

    by potholer54 44,733 views

    This will have to be the last video in the Monckton Bunkum series, because he's made so many mistakes in his presentations it will take at least three more videos to debunk them all, and I'm getting tired of having to correct him. So I've issued a challenge to Monckton fans in this video -- instead of finding things…

    This video looks at the scientific research to answer three basic questions: 1) Was the Medieval Warm Period global? 2) Was it warmer than today? 3) And what does this all mean anyway? I examine the internet feud over the hockey stick and the various myths and misinterpretations about the Medieval Warm …

    CORRECTION at 8:10 -- Solar output was around 4% weaker during the Cambrian-Ordovician 'greenhouse' period, not 6% (Ref "The faint young sun problem" - Georg Feulner, American Geophysical Union Review of Geophysics, 2012). This does not change the challenge to explain why the Earth was much hotter …
