English, 51, married with two teenage children. Engineering background with interests in physics, the environment and astronomy, also modelmaking, painting and music. When I first became interested in Yahoo Answers, I anticipated spending time hanging around R&S, hence the name Darwinist! However, I find the real problems of this world far more compelling and potentially, they don't get any bigger than global warming, so this is where I spend my time. Some of my better questions: http://answers.yahoo.com/question/index;_ylt=Ap2RjCAWFi.3uyBwblPSXNHty6IX;_ylv=3?qid=20090906163450AAc4iun http://answers.yahoo.com/question/index;_ylt=AtRThonHSPzTsIC9steQarHty6IX;_ylv=3?qid=20090408140153AAWx4qm http://answers.yahoo.com/question/index;_ylt=AlSgz4ZewDKwWbW46_jpUfXty6IX;_ylv=3?qid=20090424114058AAGvM0k I don't get on here as much as I used to - my life in the real world is rather complex these days and demands much of my time.

  • Will 2020 be the warmest year of the instrumental record?

    Normally a record year is as a result of a strong El Nino as well as the underlying warming trend.  Whilst we have seen a  weak event in recent months, I wouldn't have expected this to be sufficient to break the record.

    Yet the year is running warm so far, with a new record a distinct possibility.

    https://www.noaa.gov/news/june-2020-tied-as-earth-...

    So could there be something else going on?  Could there have been a reduction in Global Dimming from aerosols, as a result of reduced emissions during lockdowns; dimming that would normally offset some of the warming?

    Of course, one warm year is neither here nor there; it's the underlying warming that gives cause for concern.  But for those who are interested in the detail ...

    How warm do you think 2020 is likely to be and, if it does break the record, what do you think the main factors will have been?

    Thanks in anticipation ...

  • Who's still out there?

    Just wondering where the regulars have all gone.

    So, proponents and skeptics; if you see this, just feel free to say "Hi" and add anything about what you're doing now, your view on the current state of this place, what would have to change if you were to come back, anything really; if I recognize you I'll put you in the draw for best answer.  Thanks in anticipation ...

  • Global Warming regulars; how happy are you with your government's response to the Coronavirus pandemic?

    What are they doing and, if you are not happy with that, what else would you like to see done?

    Thanks in anticipation; I see this as a neutral question and will keep this in mind when picking best answer.

  • Global Warming and Climate Change: What should I read next?

    Life is getting rather busy and will continue be so well into this year, so I need to take a break from here for a while. Hopefully there will still be a YA/GW section to come back to; if there is, then I would like to return as a more effective contributor.

    To that end, what should I be reading to broaden my knowledge of climate change?

    All I have really looked at in depth is the greenhouse effect itself. My knowledge of other areas; feedbacks, climate sensitivity, weather changes etc, is less good; just what I have picked up here.

    To give you an idea of the level, the last book I read was GW Petty's, A First Course In Atmospheric Radiation; an excellent book, aimed at undergraduate students of Meteorology and climatology.

    So, with that level in mind, any recommendations?

    Thanks in anticipation; hope to be back in the summer.

  • Which source of global temperature data do skeptics prefer these days?

    When I first took an interest here about 11 years ago, skeptics were quite content with GISTEMP, since they could, by picking the 1997/98 El Nino as a starting point, draw a flat trendline to the most recent data and claim that the warming had stopped. But, as the underlying trend continued upwards, this ceased to be possible, so they switched to the RSS satellite data and continued with their claim of a pause. But RSS made some changes and the pause floundered. Luckily, UAH also made some changes and the pause was back on, eventually lasting for around 18 years, providing UAH was used. But now, with the underlying trend continuing upwards, they are unable to coax a pause out of any of the data.

    So do they stick with UAH as the last one in favour, also the one that shows the least warming?

    Do they have another one that better suits their purposes?

    Or do they now reject all of them as being somehow untrustworthy, flawed or dishonest?

  • Is there any reason to be skeptical of the greenhouse effect itself?

    Leaving aside the question of the consequences of warming and what we should do about it; is there any reason to be skeptical of the greenhouse effect itself?

    Is there any reason to be skeptical of the GHE as the reason Earth's surface temperature is around 33C higher than it needs to be for equilibrium, and for the increase in greenhouse gasses to be the main, if not the only reason, for the current warming?I

    If there is, then exactly what is it you are skeptical of and what alternative explanation(s) do you think more credible?

  • Is there any reason to believe that the current warming is a continuation of the recovery from the Little Ice Age?

    Question repeated due to the activities of the troll.

    I would be interested to see any evidence to support the idea that the current warming is a recovery from the LIA. Looking at the instrumental record, temps were fairly flat in the second half of the 19th century and early 20th, so isn't it likely that any recovery was over by then?

    http://woodfortrees.org/graph/hadcrut4gl/mean:12/p...

    Also, if the current warming is not due principally to increasing GHG's, then what IS it due to?

    Or is increasing GHG's the best; indeed the only reasonable explanation?

  • What can you tell me about wildfires. ...?

    ... in the context of global warming?

    Question repeated due to the activities of the troll.

    So what can you tell me about them?

    Whatever you call them; wildfires, brushfires, bushfires etc. Why do they occur and why, (assuming they are) are they expected to increase in a warming environment? Is there any evidence, so far, that they are increasing, either in number or intensity?

    Looking at the news, in California, the Amazon and currently Australia, it certainly seems that way ...

  • Global average temperatures; What do you think will happen over the next couple of decades?

    As this decade draws to a close, it is clear that it will be warmer than the 2000 s, and by a similar margin to that of the 2000 s over the 1990 s. (Still no sign of the imminent cooling that some on the "skeptics" side have been predicting)

    But what about the next couple of decades?

    Assuming things continue more or less as they have been, regarding GHG emissions, volcanic activity etc, (probably a reasonable assumption for a couple of decades of so) what do you expect to happen to the rate of warming?

    ... continue more or less as it has been for the last few decades? ... increase? ... decrease, stop or reverse? (cooling)

    What do you think is most likely and what do you see as the main factors?

    Finally, whatever your politics, religion and global warming views, please accept my best wishes for the season and for a prosperous 2020.

    Thanks everyone.

  • Now that it's over, what is your view on "The Pause" ...?

    By "The Pause" I mean that period, starting around 1997, in which it was possible to draw a flat trendline, which some people interpreted as meaning Global Warming had stopped.  Depending on the data set selected, this could be done for a period of about 18 years.

     "Skeptics" sometimes claim that the pause was somehow got rid of, but they are wrong.  It is still there in the data, only now you need to carefully select the end point as well.

    http://woodfortrees.org/plot/uah6/plot/uah6/from:1...

    So what is your view on this;  Did global warming stop?  Has it now resumed?  Or was there insufficient evidence to make the claim in the first place?  Was there no pause to explain?

    On what evidence do you base your view?

  • How wrong was climate change "skeptic" Didier Drogba .... ?

    ... who also, if memory serves, went by the name of Randall.

    I came across this question more or less by chance. It was penned about 10 years ago at a time when "the pause" was taking root in the fertile soil of "skeptic" imagination. But how accurate did it turn out to be? And what does it say about "skeptics" and their understanding of statistical significance?

  • What do you make of this post from the climate change skeptic, Roy Spencer?

    Not directly to do with Global Warming, but of interest since skeptics sometimes try to claim that the Earth s speed of rotation explains some of all of its elevated temperature.

    https://www.drroyspencer.com/2016/09/the-faster-a-...

    Now my first instinct was that he was wrong but, having read and considered it, I m no longer sure.

    So what do you think; does rotation speed have an effect? Or if not, then in what way is he going wrong?

    I know it doesn't trip off the tongue quite so well, but wouldn't "slightly below average solar minimum" be more accurate?

    Are they trying to "big up" something that, in the context of global warming, is a relatively minor event?
