So sad discussions like this seem to be increasingly rare. She really touched on so many of the key variables in this science, the combined effects of which must be understood in order to understand global climate. At ~ 3:10 she notes that temperature increases result in releases of greenhouse gases (CO2). I would also offer that temperature increase would give rise to more water vapor. While she did not mention H2O specifically, maybe she included in under "greenhouse gasses". I find the question of how the elevated UV radiation levels during an active Sun could influence climate intriguing. It seems the more we look, the more we realize we do not know, at least to those who seek acts and truth. I respect scientists who take this approach, while those who insist "the science is settled" I find especially annoying!

So how does cooling "naturally" cause warming??? kzbin.info/www/bejne/oWbCq6OgmteEfNE Again the sun does and has not always led changes in CO2 eg the P-T extinction event where massive volcanoes and giant coal seams catching alight caused [CO2] to climb leading to GW. kzbin.info/www/bejne/fHOpZ3lqd85pick kzbin.info/www/bejne/mnnSq52Fjq2Emqc Water vapour is controlled by temp. CO2 controls temp so as [CO2] increases so does water vapour creating a feedback mechanism. We don't pump 10 billion tons of water vapour into the air each year as we do with CO2. Cosmic rays should also cause cooling as we warm. skepticalscience.com/cosmic-rays-and-global-warming-advanced.htm Clouds also show a net zero or slight +ve feedback. Also controlled by temp and CO2.

Hate to break it to you, she does show how CO2 is the cause of the current warming. Watch some of her other videos for more explanation. This just goes to show how little you understand the science. As for the solution it is to remove tax. Currently you pay a giant big government FF welfare tax they call "subsidies". $5.3 trillion a year to cause AGW when an INVESTMENT of 10% of that is required to address AGW. That is 10x the HANDOUTS to FF billionaires than the net worth of the entire RE sector (as of 2015). AGW effects the poor and kills 7 million a year and relies on constant wars for oil and genocide.

[@ColinMill1]

A wonderfully clear discussion of this aspect of the science. Thank you. I was interested to hear Joanna say at 15:39 that the radiometer instrumentation isn't quite there yet - a very important point to make in the face of those talking about the science being settled. Unfortunately there are many other areas where the instrumentation is, or has been, lacking. I did my Ph.D in cloud microphysics in the 1970s and spent some 20 years in cloud physics research. Clouds remain rather poorly understood while having the potential to massively modify the radiative balance of the Earth interacting, as they do, with both incoming and outgoing radiation over most of the solar spectrum (cf. CO2). Small changes to, for example, the Cloud Condensation Nucleus spectrum (CCN) could change the albedo and the lifetime of clouds that in turn could affect the radiative balance. Unfortunately, there are many problems on the question of CCN - a lack of any significant and reliable historical measurements combined with an incomplete understanding of the sources (especially those of organic origin that may have been modified by, for example, land usage, changes in vegetation type etc.). Certainly in my day you could depress yourself about your chances of doing meaningful work in cloud physics simply by running two notionally identical CCN counters side by side sampling the same air only to observe that they didn't agree by factors of 50% or more.

[@grindupBaker]

Yes cloud effect uncertainties make quantity uncertain and quantity is what it's about. Still, as you know as a physicist, the temperature changes by themselves are proof positive that increased so-called greenhouse gases (GHGs) are causing some warming the last few decades irrespective of whatever other things might or might not be simultaneously attempting to cool or warm.

[@gavinminion8515]

Yes, again I would like to point out that it is the natural effects which are not fully understood. Whilst the man made effect is not completely clear, what is clear is that our emissions are causing a temperature rise. To say otherwise is like saying : "You can't tell me EXACTLY what will happen if I pick a fight with a bear, so therefore it cannot be wrong to pick fights with bears"

@@gavinminion8515 The problem is that we are betting the farm on the belief that if we stop GHG emissions the warming will stop.

This may sound far-fetched but bear in mind that the IPCC have gradually shifted their stance over the last 30 years and, for example have, in the 2018 interim report, lowered their estimate of the warming rate from 0.3C/decade to 0.2C/decade (a value that, had you subscribed to say 25 years ago, would have earned you the “denier” tag). The assertion that the medieval or Roman warm periods were confined to Europe or moderate in duration or magnitude is not accepted by historians. I tried it on an Oxbridge medieval historian as I just happen to have one in my family and apparently there is documentary evidence from China and Japan along with masses of European evidence for an extensive MWP. So, it is entirely possible that we could go back to the conditions of the medieval warm period - CO2 at 300ppm but with a climate warmer that today and sea levels rising at about 1.5mm/year (as they have been for centuries). I have been working for the last decade on renewables and I agree completely with Bill Gates that the current renewables technology is totally incapable of replacing fossil fuels. Expenditure of huge effort to say nothing of huge CO2 emissions on creating renewables infrastructure that is simply not fit for purpose is madness.

@@ColinMill1 Hi Colin, the point of my analogy is that we should not be fighting the bear. To take it back to the debate, whilst I agree that a simple switch away from fossil fuels is simply not practical at present. We need to begin engineering away from them immediately. Continuing to spend vast amounts on consumerist waste, fritter away natural resources and make ridiculous claims like 'I have a god given right to burn oil any way I want' is simply picking a fight with a bear which is currently asleep, and us 'hystericals' just want it to stay that way.

@@gavinminion8515 I think we may be in agreement. I have always contended that we will need to transition to renewable energy sources eventually. I went into atmospheric physics in the early 70s when it was a largely forgotten backwater subject because I am passionate about the environment - a trait I share with many of the other scientist like Spencer and Heller who also have the offensive denier tag thrown at them. Like Heller I have done much to minimise my footprint on this Earth (and done so long before that term was coined) I'm on only my 3rd car since 1982 - all bought used (it would be fewer if someone hadn't T-boned the first in the side and written it off) and used them only when public transport is incapable of doing the job (I've tried carrying an 12ft long item on a bus - they chuck you off). We heat the house primarily from wood from our own land (not a solution open to many in a country with over 400 people /sq.km.) - I could go on. I and my co-workers in the renewables research are trying to make them a practical proposition but even with the exciting materials research that is going to come on line in the next 20 years it remains a massive task.

The best explanation i have heard. Good to hear about a serious grown up's research. instead of a climate alarmist informed by the main stream media.

[@GuitarDaddio]

This is fantastic. I am hearing that variations in the magnetosphere impact the solar radiation reaching the surface of the earth. I am hearing the idea that the magnetosphere weakens during times of low sunspot activity thereby allowing more radiation to reach the surface of the earth even though the sun, itself, is producing less radiation. I am also hearing that the hole in the ozone layer occurred during times of extreme cold weather at the southern pole, and that there is a significant hole in the northern polar regions now that we are seeing extreme cold weather at the North Pole. Finally, there is good research that shows the high temperatures in the northern hemisphere are closely related to the periodic variations of the ocean currents in the Atlantic. The currents vary on a 60 year cycle leading to warming trends that last 30 years and cooling trends that last 30 years. The current in the Atlantic could appear stable (linear), but most phenomena can become unstable. The biggest risk of man-made climate change could be that we do something to hasten the disruption of the Atlantic Ocean currents. When that happens--whether or not it is we who do it--all bets are off. I am not saying that I believe these hypotheses. I am saying that they are, indeed, potential parameters that need further investigation and incorporated into future models if found to be significant. Finally, we should all trust The Science before trusting The Consensus because The Consensus follows The Money and The Money follows The Power and The Power, currently, has lost The Plot.

Much of the cooling of the little ice age preceded the volcanic eruptions of the late 1700’s, but the volcanic eruptions did cause further cooling.
