Climate change: Our time really is running out

This video features Professor Peter Wadhams, leading Arctic scientist Cambridge University, interviewed by Judy Sole, the University of Earth. It is very topical and very important.

Professor Wadhams argues that politicians are dragging their feet on the climate change issue. The approach of trying to limit CO2 emissions just won’t work. We have to put serious money into research methods of removing CO2 from the atmosphere and countering methane emissions from seabed permafrost.

He discusses the radical reduction of arctic ice due to global warming and warns that this is leading to release of methane gas from underwater seabed permafrost and this could have relatively rapid effects on global warming.

Thanks to Richard for bringing my attention to this video.

  2. Hi Ken

    You might think me a luddite for even questioning, but I’m still reading to figure out where I sit with man-made climate change. I put the above Youtube out to the skeptic community, and they came back with the below link in refutation of the claims in this clip … wondering if you care to comment on it?

  5. Mark, that blog page does not link to their source. However, the figure they use take just 2 points over 6 years so it looks like an extreme case of cherry-picking. That seems to happen a lot with wishing to discredit the climate change science on arctic ice.

    In short, have a look at the data over a long term period and evaluate the trends. Be very waryof people who use just 2 data points, and refuse to provide a citation.

  10. It’s worth pointing out that Wadham’s views on the fate of the sea ice and the seabed methane “emergency” are considered to be out on the fringe by his peers in the Arctic science community. That doesn’t mean he’s wrong to be concerned, just that informed opinion considers the rapid retreat of the sea ice (and rapid melt of Greenland) to bad enough without having to overstate the case.

  14. The “CO2 drives climate” hypothesis – causing warming which produces a catastrophic climate condition or net disease state – predicted that BOTH the Arctic and Antarctic areas would lose sea ice via “Polar amplification” – with increasing CO2 acting in like manner in both Polar areas.

    But the Antarctic has slowly increased its sea ice extent over ~the same time period measured for the Arctic’s decrease*. Therefore, the whole prediction itself is wrong, regardless of what the Arctic does….as are ALL of the “CO2-Climate Change” predictions: “the science”, as they call it and which they think must work in the real world “because CO2 is a greenhouse gas”, hasn’t got a prediction right yet! Therefore the hypotheses claiming “CO2 drives climate” are Scientifically Falsified.

    In other words, “mainstream” Climate Science has been unable to find any of its predicted empirical effects from an increasing CO2 concentration which have then occurred in the real world.

    Therefore there is something seriously wrong with “the science” of mainstream Climate Scientists.

  15. Goodness me. Last post, because I can’t debate with people like Richard: that attitude is toxic.

    But a funny thing Richard; I have, merely, a healthy scepticism regarding all matters re climate (and this mainly because the scientists did not help their cause by originally manipulating their figures in the opening ambit: that was the real damage here, as they politicised the science).

    I have an equivalent scepticism, as you do following your name-link, on many aspects of our political and legal system. Like you I think Peter Ellis has to be exonerated and compensated. (My piece that mentions Ellis is here: http://lifebehindtheirondrape.blogspot.co.nz/2015/01/retrieving-roger-suttons-corpse-from_22.html ) The portion on Peter Ellis starts about half way down that piece, at the heading with his name in it.

    I am trying to understand the science around climate in mind of that original manipulation raising questions of ‘alarmist panic’, every bit as valid as the nonsensical ‘moral panic’ you note around the Ellis case.

    With that, great blog Ken. I won’t stick around on this thread anymore to inflame a senseless ego war.

  17. Mark, your retreat after making unsupported claims of fraud is hardly honest.

    Please support your claim that scientists did not help their cause by “manipulating their figures in the opening ambit.” Manipulation of data is scientific fraud which is strongly condemned in the scientific world. The deniers may get away with it but scientists usually lose their jobs for this and become unemployable.

    Is this of the same level as the image you posted relying on 2 data points? You really should not retreat after among such charges.

    Seems to me that while you claim to be open-minded or undecided in this climate issue you are uncritically buying into, and repeating, propaganda produced by deniers.

    From what you have written here your “healthy scepticism” is pretty one-sided. It really doesn’t deserve the word “scepticism” and your uncritical acceptance of such serious charges certainly is not “healthy.”

  18. Sorry Ken, but what? ‘My retreat’ (What are you talking about?)

    Jesus you guys: must you demonise everyone you ‘think’ doesn’t agree with you? Read my first linked piece above on what I think of this BS.

    I am undecided. Your and Richard’s attitude, however, puts me ’emotionally’ with the deniers out of pure pigheadedness (not science). So what do you hope to achieve with that? I hope Richard holds no public position or power over people, because, to repeat myself, he a cynical, toxic tyrant in his bearing, who must belittle those who don’t agree wholeheartedly with his every word.

    Here’s the deal:

    I have no expertise in climate science – never said I did (let’s debate philosophy, politics, or economics some time.) On my own blog I have only two posts that even broach it.

    I found the Youtube clip compelling, so I asked the question of the sceptic community and brought that back here to see the rebuttal and if I agreed with it. Because this is an important debate. Though I wasn’t trying to even start a debate, here: just how easily it could be defended.

    You replied, Ken, with your own graph, and I largely accepted your point. At that point, there was no need for me to carry on.

    But if you wanted to carry on, then you might want to look at my Twitter TL for today: you’ll see there is much debate around this, the summary of which is, quote:

    “NSIDC Clearly thought there was LESS Ice in the 60’s and 70’s… why start at 1979 all the time??”

    That is to make the ‘withdrawing ice’ argument work you have to start your graphs at 1979, but you get a differing interpretation if you start earlier at 1974.

    Who is right?

    I still don’t know.

    I remain on the fence (perhaps tilted slightly to ‘your’ argument, intellectually, but hating the way you go about it.).

    So, whatever the Truth is, with this inquisitorial zeal of your post above, giving me a position I don’t even hold, then using that to call me dishonest … with that attitude you can go to hell. I’m gone.

  19. Mark, you made an unsupported claim of scientific fraud. That is a serious claim and I have asked you to back it up. Now you reply without even referring to it!

    If you refuse to stand by your claim of scientists manipulating their figures then why not apologise and withdraw it? If you do stand by it then provide some evidence – don’t leave it as a statement we should all assume. It isn’t.

    You claim to be sitting on some sort of fence – if that is so then surely claims of scientific fraud are not warranted. Especially as you also claim to have no expertise in that subject.

    As a scientist I welcome critical assessment of the science. But slanderous claims of fraud without any evidence really do make me angry. It makes rational discussion impossible.

    And it doesn’t help for you to pretend you have not been slanderous by accusing me of “inquisitorial zeal” when I request you back up a serious charge with some evidence. That is simply avoidance and refusing to face up to the need to support such claims.

    It’s pretty simple – just provide evidence for your claim. I welcome evidence, it’s unsupported slander I object to.

  20. Are we reading the same comments?

    You say I am accusing someone (who, you?) of scientific fraud. And that an open questioning is ‘slanderous’, I must back myself up with evidence. When I have said from the get-go I am a ‘luddite’ and have no expertise in climate science (but I am well read enough to know there is active scepticism to the claims of climate science, such as on this clip.)

    Let me repeat my very first comment, quote:

    “You might think me a luddite for even questioning, but I’m still reading to figure out where I sit with man-made climate change.

(Which will not doubt have you obsessing on if I have just called you insane – no, I haven’t, but the climate responses here fit the template of what is so objectionable about this entire debate.)

    But evidence? You have the data (I’m not the scientist): post the graph you put up above, but with data points starting at least at 1974, or better, 1970. Let’s have a look at that, and let’s start with that. If it shows similar downward trend, the ‘science’ is right (and I hope it would be).

    There would still be a downward slope, however, much more gradual, from 1971, plus, the ice volume from 2008 appears to be at least constant, if not increasing … only future data will show where that ends. Agreed?
