This free online course provides the basis for understanding the underlying physical processes governing climate variations in the past, present and future.
In the course, we focus on explaining the main external forcing mechanisms such as the sun, volcanoes, and changes in greenhouse gasses and aerosols, which can contribute to changing the global energy budget and initiate climate variations.
We also describe the important role of internal feedback mechanisms and the energy transport in the atmosphere and ocean, in order to understand regional variations in climate.
Through this course, you will gain an in-depth understanding of the complexities of the climate system, and be able to put the recently observed, man-made changes in climate in the context of past natural changes.
That looks like an interesting course Trakar but I'm currently doing two FutureLearn courses (on earth observation satellites and Homo floresiensis) so I can't really fit it in.
I've signed up for another FutureLearn course on the causes of climate change which starts next month, and which others here might find of interest:

Ohai! I was searching around for something different, and noticed that you were talking about me, and wondered if you were misrepresenting me as much here as you are at the other place.I have one AGW proponent on another forum
Yep, turns out you are. I'm not claiming that current temperatures were projected by IPCC's FAR in 1990 in order to belittle the "crisis aspect" of climate change, I'm claiming that current temperatures were projected by IPCC's 1990 FAR because you've made claims that we're decades ahead of the IPCC's worst-case scenario, and your claims are demonstrably false, and quite obviously so to anyone with a working familiarity with the work of the IPCC, and with global temperature data. I agree with you that there's a climate crisis, but disagree with the strategy of telling hyperbolic lies that diminish the credibility of scientists doing work to accurately model what we're doing to the climate, such as this:who keeps belittling the "crisis aspect" by claiming this was all foretold by the 1990 IPCC projections.
Not only did I cite for you the exact page references of where you could find such projections, and reproduce the relevant projections in our discussion, but you yourself even posted IPCC charts showing accurate projections of current temperatures (although admittedly you misrepresented them - through either dishonesty or incompetence - as not doing so).I could not find any IPCC projections that got us over 1C before 2016.
Nope, that another misrepresentation. I've defended consensus climate science's ability to project temperatures. I haven't said we have the impacts of that warming "under control" - that's certainly not a direct quote, nor a conclusion that anyone could reasonably draw from my posting on the subject, as I've consistently argued that "the powers that be" by which I assume you mean various world governments, are doing far less than is required to avert serious impacts.Anyway - he implies that because it was projected ....it's all "under control" ...the powers that be have a handle on this......which I think is far from reality.
And yet your recent attack on me at the other place started when I said that I thought that the reaction of climate scientists to 2016's record warmth should have been "We told you so!" rather than "We're shocked!". Are you now coming around to my view?I AM glad to see more attribution from climate scientists and more agressive ...we were right ...attitude.
Again, in temperature terms, cliamte science has an excellent track record of accurate projection. That's not the same as predicting of local impacts, which I've explicitly agreed with you are more uncertain, and potentially severe based on the magnitude of current warming.Trakar ...a poster in another forum is claiming the collective we ...climate scientists...have a firm handle on what will unfold over the next decades.
Again, that's not a direct quotation, nor is it anything remotely resembling my position. It's a figment of your imagination: a worthless strawman.He claims we will not get into 1.5-2C before 2050 or so and is sorting of pattinghis readers on the head and saying "not to worry, we know what's coming"...
Again, that chart shows an almost unanimous view that the 3.0 TCR that Mann's projection of 2C by 2036 is based on is very unlikely to be accurate. In particular, such a TCR is not consistent with observed warming over the last few decades. Your casual reading does not accord with consensus climate science, for whatever reason that may be; perhaps you favour sources that tend towards the hyperbolic?My position is we DON'T have a handle on this they way he portrays.....we don't even know climate sensitivity as yet.....
[link removed as new posters like myself can't even quote links]
[link and image removed as new posters like myself can't even quote links or external images]
And from what I have seen in casual reading ...evidence seems to support the higher values of TCR over the last while.
Thoughts???
Hi Trakar, pleased to make your acquaintance in person, rather than just being a person you've talked about without introduction.In my consideration, you have a better handle on this material and the underlying science, than he appears to. That said, his statements are largely in accord with the 20+ year old reports and mainstream science understandings he is using as references. What he doesn't seem to understand is that the evidence and the science understandings have grown and evolved over the last 20+ years and his understandings are as dated as the sources he is referencing.
I wasn't dismissive of reports that current warming was unexpected, I provided numerous citations showing that current levels of warming were projected.Yeah ....I really did not want to bring him up to speed so was dismissive just as he was dismissive of the reports that the level of warming was not expected even taking El Nino into consideration.
Again, this is neither a direct quote, nor an honest or reasonable representation of my posts. I feel we'd be able to have a far more productive discussion (which contained far more agreement than disagreement) if you'd stop misrepresenting my position in order to have something to (patronisingly) disagree with.I don't care except some others accepted his "it's okay IPCC has it covered".
Anyway, nice to meet you all - there's some interesting discussion here, but I'm too busy to contribute to multiple fora at present. I may, however keep an eye on this thread to see if what I've written elsewhere recurs as a subject.
Apologies to those who have no idea what this is about, but Macdoc has imported a disagreement between the two of us elsewhere to this forum, and while I'm able to address his misrepresentations here, I don't yet have enough posts to link to the original context for this discussion, so for now, I've got little more to say than some straightening of the record for his benefit, and that of anyone who may have read his rather idiosyncratic take on our exchange that he posted here.
I have taken the course and can highly recommend it to others, primarily because it helps in communicating the concepts behind climate science to others. Nothing too in depth, but a very good basics with enough good sources for further study optional.Online course on climate science denial "Making Sense of Climate Science Denial," starts next Tuesday, Aug. 9.

Unfortunately not. I get my own information all over the place, and try to read actual papers when I have the time (and if they look interesting). But everywhere I know of that allows discussion has its share of denial and hyperenthusiasm.Run! Run away as fast as you can! Can you recommend a forum where AGW is dealt seriously?

Hi Trakar, pleased to make your acquaintance in person, rather than just being a person you've talked about without introduction...
"...current temperatures are far beyond what the IPCC's 1990 FAR projected. This is in fact demonstrably untrue,..."
I'm afraid that I can't really agree with your assessment that my understandings are stuck in the past. Macdoc was making very specific claims that current temperatures are far beyond what the IPCC's 1990 FAR projected. This is in fact demonstrably untrue, and to demonstrate it requires citation of both current data, and the decades-old projections whose accuracy is being contested. the IPCC FAR of 1990 is not my go-to source, but referencing it is required to substantiate a claim about its contents.
Please demonstrate that this statement is untrue.
Got something which includes and reflects the last 5-6 years of data and understanding?
It would be especially helpful if it were material actually looking at the issues under discussion as well.
My position, on the matters on which you passed judgement to Macdoc here - (so I presumed you wouldn't need it explained) is that Macdoc's claim (that current temperatures are decades in advance of the 1990 FAR's worst case projections) is not substantiable. I could be petty and say that the burden of proof is entirely on Macdoc to substantiate his claim, and given that he's made no effort to do so, I remain skeptical on that basis alone. But in fact, I'm reasonably conversant with the IPCC's work and the various temperature datasets, and know that this is not, in fact, true. aleCcowaN has provided a link to page including IPCC FAR charts that show the 1990 projections above pre-industrial temperatures. If you're not familiar enough with the data to instantly recognise that we're not decades ahead (I don't know about you, but the amount of warming observed over pre-industrial temperature seems to me like something that those interested in climate change should know without needing to look up), then you can look it up in the usual places (GISTEMP, HadCRUT, whatever floats your boat). Once I've got enough posts to post links, I can link you to where I walked Macdoc through how to do so.Nice to meet you. My discussion with MacDoc has been based entirely upon the arguments and discussions as presented by MacDoc. If you would care to state your position with regard to your understandings of anthropogenic climate change, and have clarifications, qualifications and/or references you would like to present to support your position. We can assess and discuss these issues a little more directly.
No kidding.From looking at your post, there do seem to be a few issues which should be clarified ahead of such a discussion:
The IPCC (Intergovernmental Panel on Climate Change) is an international public policy organization created by the World Meteorological Organization and the United Nations Environment Program (and largely at the behest of and under pressure from the Reagan administration).
The IPCC does not perform scientific research, it merely reviews submitted published science findings in various climate related fields, attempts to compare, relate and interpret these findings with respect to the individual fields and interactions between fields and then present this information in a manner that will help guide and define public policy decisions both within and between nations, with regard to Climate Change.
Again, no kidding. Frankly, all that sounds like a laundry list of excuses for why the IPCC could lowball warming projections, in line with Macdoc's claims that they've done so.While projections are a part of all IPCC reports, much of the information upon which these reports (and their projections) are based is both of limited selection and dated validity. This isn't to say that the underlying science or the reports themselves are invalid, merely that such analyses are based on a subset of data that is most often at least several years (and frequently a decade or more) old, in areas of science understanding that are rapidly changing and expanding.
Mainstream science, particularly published science, is inherently conservative in its assessments, analyses and projections. Thus, it should be expected(rather than surprising), that analyses, interpretations, and projections based on such tend to err on the conservative end of understandings.
To add to this, many of the assessments must also pass through the gauntlet of the groups representing the governmental interests of the nations cooperating in the IPCC and these agencies frequently require modifications in accord with their wishes before they are finalized into the official IPCC reports.
OK, now this is going to look a bit weird, because this forum doesn't allow nested quotes (something that's annoying me, as well as the need to constantly avoid more colourful expressions for my reaction to that due to the puritanical language rule), but you're asking me to demonstrate that the current temperatures are not far beyond the IPCC FAR's worst case projections.With regard to your reported claims, beyond any clarification you wish to make, please provide support and reference for:
Please demonstrate that this statement is untrue.
My original statement that Macdoc took exception to was:"far beyond" what? What the 1990 lead IPCC scientists actually believed were the most likely values and outcomes, or the worst case A1 scenarios which virtually none actually believed was the course we would actually follow?
