    An NOAA study has found that the amount of fossil fuel methane emissions have been underestimated, but they are also not the cause for the recent rise in methane emissions.

    It doesn't even have to be as yet self-reinforcing to any significant extent to make wrangling the problem more difficult.

    Does climate change, absolutely
    Is it changing today, yes
    Is it conclusive that the current climate change is caused by humans, no not by a long shot.

    There have been a number of prominent scientists of recent years that have resigned from their positions calling out studies and reports as pseudoscientific at best and a corporate fraud at worst.

    What like 10 out of 20,000?

    https://en.wikipedia.org/wiki/Harold_Lewis

    Harold Lewis resigned from the ASP in 2010 and passed away in 2011. He published a book in the 1990s warning of the dangers of technology. Based on his letter of resignation the ASP setup a committee to even further investigate the ethical standards of its members. Lewis declined their offer to be a member of the committee.

    Your argument that the current dramatic change to our planet's climate is not man made is absurd. Lewis himself warned of the dangers of rising CO2 levels leading to catastrophic warming of the planet. It's an exceptional claim that man isn't responsible when there's no other plausible explanation. Every other possible cause has been investigated and found lacking.

    If it wasn't anthropogenic then we're in even more dire straights. The consequences will be the same regardless of the cause but if our activity is the cause it'd be easier for us to deal with than if it was say due to an increase in solar activity.

    I do agree, there's quite a lot of "corporate fraud" going on. Lots of snake oil solutions being flogged to an uniformed public and with government subsidy. The great fraud is that this is an issue we can "science" our way out of and continue business as usual.

    20,000 is that a number you just made up, of course it is.
    But carry on regardless

    And here is Berkeley Earth's take on it..
    But imortantly..
    So putting it into perspective, 2016 was no more or less exceptional than 2014.

    For anyone who wants a dissenting science: http://www.ncpa.org/pdfs/ba337.pdf

    In brief the current temperature rise is within the range of variability over the past 10,000 years. It's also true that in the 1970s there was considerable alarm over global cooling.

    From the same paper we do see a significant rise in temperature in the recent period of Earth's history and at an unprecedented rate. The problem here is bore hole data is increasingly smeared (averaged) over time.

    Spare a thought for the 2 million people living in greater western Sydney, which makes any part of Adelaide almost antarctic by comparison.

    In the calendar month just gone, 8 days recorded above 40 degrees, and a mean maximum temperature of 34 degrees. The highest temperature this year was 45.1 degrees recorded at Penrith, which has recorded 46.5 a few years back, and as high as 48 degrees historically.

    But it's not only hot, it's humid too, to the point where evening dew point readings can rival those in coastal areas of far north Queensland.

    I personally know someone who moved from Mackay to Penrith for a year, and he moved back to Mackay to get some relief from the heat and humidity, which was in his words "unbelievable".

    Whether it's related to climate change or urbanisation, or some combination of the two, Greater Western Sydney is now hotter than any part of Perth, Adelaide or Brisbane, and is more humid than most of Brisbane too.

    Ftr, for the month gone in Mackay QLD, the highest maximum temperature was 33.6C, which is lower than the mean daily temperature in Sydney's west.

    That part of Sydney has always been hot. What makes it worse out there is the temperature doesn't drop during the night. Move further West up into the mountains and it does.
    As to why it's now such a noticeable issue, I'd say a combination of factors. By itself urbanisation does two things. Lots of black asphalt and dark roofs plus simply more people living in the area to notice it. On top of that the few that did live out there in the past lived in timber dwellings which don't have the thermal mass of brick. No doubt climate change is also a factor but it's influence is complex.

    "Dissenting Science": A 16 year old paper from a political think tank (summarising others' work) that claims there's no reliable way to quanitfy preindustrial climate data, then tries to anyway with a single proxy, a short timescale (a cherry picked starting point), and no attempt to quantify uncertainty.

    Ditto the last 17 years too.

    If the media is anything it's consistent.

    A: You post a rubbish quote.
    B: You don't post a source to the said quote.
    C: The quote has no factual, scientific or data evidence.
    D: The quote blames the media (okay?) and says climate change is hysteria.
    E: You're agreeing to said rubbish quote.

    It's from the political (not scientific) article RobRoySyd linked a few posts earlier

    If this is an ABC style fact check, you've just scored an 'F'.

    Perth is renowned for being in the 40's over summer, hell breaching 45 nearly every other year....

    I think it's been over 40 2 days so far?
